Azure doesn't directly bill based on the resource cost. Charges for a resource are calculated by using one or more meters. Meters are used to track a resource's usage throughout its lifetime. These meters are then used to calculate the bill.

For example, when you create a single Azure resource, like a virtual machine, it has one or more meter instances created. Meters are used to track the usage of the resource over time. Each meter emits usage records that are used by Azure to calculate the bill.

For example, a single virtual machine (VM) created in Azure may have the following meters created to track its usage:

Compute Hours, IP Address Hours, Data Transfer In, Data Transfer Out, Standard Managed Disk, Standard Managed Disk Operations, Standard IO-Disk, Standard IO-Block Blob Read, Standard IO-Block Blob Write, Standard IO-Block Blob Delete

Question 3

Your company plans to migrate all its data and resources to Azure.

The company's migration plan states that only platform as a service (PaaS) solutions must be used in Azure.

You need to deploy an Azure environment that supports the planned migration.

Solution: You create an Azure App Service and Azure SQL databases.

Does this meet the goal?

Answers


Explanation (click to expand)

Platform as a service (PaaS) is a complete development and deployment environment in the cloud, with resources that enable you to deliver everything from simple cloud-based apps to sophisticated, cloud-enabled enterprise applications. You purchase the resources you need from a cloud service provider on a pay-as-you-go basis and access them over a secure Internet connection.

Like IaaS, PaaS includes infrastructure-servers, storage and networking-but also middleware, development tools, business intelligence (BI) services, database management systems and more. PaaS is designed to support the complete web application lifecycle: building, testing, deploying, managing and updating.

PaaS allows you to avoid the expense and complexity of buying and managing software licenses, the underlying application infrastructure and middleware, container orchestrators such as Kubernetes or the development tools and other resources. You manage the applications and services you develop and the cloud service provider typically manages everything else.

Answers


Explanation (click to expand)

Elastic computing is the ability to quickly expand or decrease computer processing, memory, and storage resources to meet changing demands without worrying about capacity planning and engineering for peak usage. Typically controlled by system monitoring tools, elastic computing matches the amount of resources allocated to the amount of resources actually needed without disrupting operations. With cloud elasticity, a company avoids paying for unused capacity or idle resources and doesn't have to worry about investing in the purchase or maintenance of additional resources and equipment.

While security and limited control are concerns to take into account when considering elastic cloud computing, it has many benefits. Elastic computing is more efficient than your typical IT infrastructure, is typically automated so it doesn't have to rely on human administrators around the clock, and offers continuous availability of services by avoiding unnecessary slowdowns or service interruptions.

You plan to migrate a web application to Azure. The web application is accessed by external users.

You need to recommend a cloud deployment solution to minimize the amount of administrative effort used to manage the web application.

What should you include in the recommendation?

Answers


Explanation (click to expand)

IaaS (Information as a Service). IaaS is the most basic level of cloud-based solutions, which refers to renting an IT infrastructure as a fully outsourced service. In this category, the cloud provider lets you rent servers, VMs, storage, network and operating systems on a pay-as-you-go basis.

Examples: Amazon EC2 and S3, Google Compute Engine, Windows Azure.

PaaS (Platform as a Service). PaaS is the cloud solution where, apart from providing an infrastructure, cloud providers also issue an on-demand computing environment to develop, test, run and collaborate with components such as web servers, database management systems, and software development kits (SDKs) for various programming languages.

Examples: AWS Elastic Beanstalk, Heroku, Windows Azure, Force.com, Google App Engine.

SaaS (Software as a Service). SaaS providers offer fully functional web-based application softwares tailored to a variety of business needs such as project tracking, web conferencing, marketing automation or business analytics.

Examples: Google Apps, Microsoft Office 365, Gmail, Yahoo and Facebook.

Explanation (click to expand)

Private cloud is a type of cloud computing that delivers similar advantages to public cloud, including scalability and self-service, but through a proprietary architecture. Unlike public clouds, which deliver services to multiple organizations, a private cloud is dedicated to the needs and goals of a single organization.

As a result, private cloud is best for businesses with dynamic or unpredictable computing needs that require direct control over their environments, typically to meet security, business governance or regulatory compliance requirements.

There are three general cloud deployment models: public, private and hybrid.

A public cloud is where an independent, third-party provider, such as Amazon Web Services (AWS) or Microsoft Azure, owns and maintains compute resources that customers can access over the internet. Public cloud users share these resources, a model known as a multi-tenant environment.

By comparison, a private cloud is created and maintained by an individual enterprise. The private cloud might be based on resources and infrastructure already present in an organization's on-premises data center or on new, separate infrastructure. In both cases, the enterprise itself owns and operates the private cloud.

A hybrid cloud is a model in which a private cloud connects with public cloud infrastructure, allowing an organization to orchestrate workloads across the two environments. In this model, the public cloud effectively becomes an extension of the private cloud to form a single, uniform cloud. A hybrid cloud deployment requires a high level of compatibility between the underlying software and services used by both the public and private clouds.

When an organization properly architects and implements a private cloud, it can provide most of the same benefits found in public clouds, such as user self-service and scalability, as well as the ability to provision and configure virtual machines (VMs) and change or optimize computing resources on demand. An organization can also implement chargeback tools to track computing usage and ensure business units pay only for the resources or services they use.

Private clouds are often deployed when public clouds are deemed inappropriate or inadequate for the needs of a business. For example, a public cloud might not provide the level of service availability or uptime that an organization needs. In other cases, the risk of hosting a mission-critical workload in the public cloud might exceed an organization's risk tolerance, or there might be security or regulatory concerns related to the use of a multi-tenant environment. In these cases, an enterprise might opt to invest in a private cloud to realize the benefits of cloud computing, while maintaining total control and ownership of its environment.

However, private clouds also have some disadvantages. First, private cloud technologies, such as increased automation and user self-service, can bring some complexity into an enterprise. These technologies typically require an IT team to rearchitect some of its data center infrastructure, as well as adopt additional management tools. As a result, an organization might have to adjust or even increase its IT staff to successfully implement a private cloud. This is different than public cloud, where most of the underlying complexity is handled by the cloud provider.

Another potential disadvantage of private clouds is cost. A benefit of public cloud is cost mitigation through the use of computing as a "utility" -- customers only pay for the resources they use. When a business owns its private cloud, however, it bears all of the acquisition, deployment, support and maintenance costs involved.

Home / Microsoft / AZ-900 / Question 7

Question 7

You plan to deploy several Azure virtual machines.

You need to ensure that the services running on the virtual machines are available if a single data center fails.

Solution: You deploy the virtual machines to two or more scale sets.

Does this meet the goal?

Answers


Explanation (click to expand)

Azure virtual machine scale sets let you create and manage a group of identical, load balanced VMs. The number of VM instances can automatically increase or decrease in response to demand or a defined schedule. Scale sets provide high availability to your applications, and allow you to centrally manage, configure, and update a large number of VMs. With virtual machine scale sets, you can build large-scale services for areas such as compute, big data, and container workloads.

To provide redundancy and improved performance, applications are typically distributed across multiple instances. Customers may access your application through a load balancer that distributes requests to one of the application instances. If you need to perform maintenance or update an application instance, your customers must be distributed to another available application instance. To keep up with additional customer demand, you may need to increase the number of application instances that run your application.

A region is a set of datacenters deployed within a latency-defined perimeter and connected through a dedicated regional low-latency network. With more global regions than any other cloud provider, Azure gives customers the flexibility to deploy applications where they need to. Azure is generally available in 46 regions around the world, with plans announced for 8 additional regions.

Answers


Explanation (click to expand)

Azure Virtual Network (VNet) is the fundamental building block for your private network in Azure. VNet enables many types of Azure resources, such as Azure Virtual Machines (VM), to securely communicate with each other, the internet, and on-premises networks. VNet is similar to a traditional network that you'd operate in your own data center, but brings with it additional benefits of Azure's infrastructure such as scale, availability, and isolation.

VNet concepts:

Address space: When creating a VNet, you must specify a custom private IP address space using public and private (RFC 1918) addresses. Azure assigns resources in a virtual network a private IP address from the address space that you assign. For example, if you deploy a VM in a VNet with address space, 10.0.0.0/16, the VM will be assigned a private IP like 10.0.0.4.

Subnets: Subnets enable you to segment the virtual network into one or more sub-networks and allocate a portion of the virtual network's address space to each subnet. You can then deploy Azure resources in a specific subnet. Just like in a traditional network, subnets allow you to segment your VNet address space into segments that are appropriate for the organization's internal network. This also improves address allocation efficiency. You can secure resources within subnets using Network Security Groups. For more information, see Security groups.

Regions: VNet is scoped to a single region/location; however, multiple virtual networks from different regions can be connected together using Virtual Network Peering.

Subscription: VNet is scoped to a subscription. You can implement multiple virtual networks within each Azure subscription and Azure region.

Explanation (click to expand)

A VPN gateway is a specific type of virtual network gateway that is used to send encrypted traffic between an Azure virtual network and an on-premises location over the public Internet. You can also use a VPN gateway to send encrypted traffic between Azure virtual networks over the Microsoft network. Each virtual network can have only one VPN gateway. However, you can create multiple connections to the same VPN gateway. When you create multiple connections to the same VPN gateway, all VPN tunnels share the available gateway bandwidth.

A virtual network gateway is composed of two or more virtual machines that are deployed to a specific subnet you create, which is called the gateway subnet. The VMs that are located in the gateway subnet are created when you create the virtual network gateway. Virtual network gateway VMs are configured to contain routing tables and gateway services specific to the gateway. You can't directly configure the VMs that are part of the virtual network gateway and you should never deploy additional resources to the gateway subnet.

VPN gateways can be deployed in Azure Availability Zones. This brings resiliency, scalability, and higher availability to virtual network gateways. Deploying gateways in Azure Availability Zones physically and logically separates gateways within a region, while protecting your on-premises network connectivity to Azure from zone-level failures.

Question 22

Your company plans to move several servers to Azure.

The company's compliance policy states that a server named FinServer must be on a separate network segment.

You are evaluating which Azure services can be used to meet the compliance policy requirements.

Which Azure solution should you recommend?

Answers


Explanation (click to expand)

Azure virtual networks are similar to LANs on your on-premises network. The idea behind an Azure virtual network is that you create a network, based on a single private IP address space, on which you can place all your Azure virtual machines. The private IP address spaces available are in the Class A (10.0.0.0/8), Class B (172.16.0.0/12), and Class C (192.168.0.0/16) ranges.

Best practice: Create network access controls between subnets. Routing between subnets happens automatically, and you don't need to manually configure routing tables. By default, there are no network access controls between the subnets that you create on an Azure virtual network.

Detail: Use a network security group to protect against unsolicited traffic into Azure subnets. Network security groups are simple, stateful packet inspection devices that use the 5-tuple approach (source IP, source port, destination IP, destination port, and layer 4 protocol) to create allow/deny rules for network traffic. You allow or deny traffic to and from a single IP address, to and from multiple IP addresses, or to and from entire subnets.

When you use network security groups for network access control between subnets, you can put resources that belong to the same security zone or role in their own subnets.

Your company has an Azure environment that contains resources in several regions.

A company policy states that administrators must only be allowed to create additional Azure resources in a region in the country where their office is located.

You need to create the Azure resource that must be used to meet the policy requirement.

What should you create?

Answers


Explanation (click to expand)

Azure Policy is a service in Azure that you use to create, assign, and manage policies. These policies enforce different rules and effects over your resources, so those resources stay compliant with your corporate standards and service level agreements. Azure Policy meets this need by evaluating your resources for non-compliance with assigned policies. For example, you can have a policy to allow only a certain SKU size of virtual machines in your environment. Once this policy is implemented, new and existing resources are evaluated for compliance. With the right type of policy, existing resources can be brought into compliance.

There are a few key differences between Azure Policy and role-based access control (RBAC). RBAC focuses on user actions at different scopes. You might be added to the contributor role for a resource group, allowing you to make changes to that resource group. Azure Policy focuses on resource properties during deployment and for already existing resources. Azure Policy controls properties such as the types or locations of resources. Unlike RBAC, Azure Policy is a default allow and explicit deny system.

Lock resources to prevent unexpected changes!

As an administrator, you may need to lock a subscription, resource group, or resource to prevent other users in your organization from accidentally deleting or modifying critical resources. You can set the lock level to CanNotDelete or ReadOnly. In the portal, the locks are called Delete and Read-only respectively.

CanNotDelete means authorized users can still read and modify a resource, but they can't delete the resource.

ReadOnly means authorized users can read a resource, but they can't delete or update the resource. Applying this lock is similar to restricting all authorized users to the permissions granted by the Reader role.

Azure Policy is a service in Azure that you use to create, assign, and manage policies. These policies enforce different rules and effects over your resources, so those resources stay compliant with your corporate standards and service level agreements. Azure Policy meets this need by evaluating your resources for non-compliance with assigned policies. For example, you can have a policy to allow only a certain SKU size of virtual machines in your environment. Once this policy is implemented, new and existing resources are evaluated for compliance. With the right type of policy, existing resources can be brought into compliance.

There are a few key differences between Azure Policy and role-based access control (RBAC). RBAC focuses on user actions at different scopes. You might be added to the contributor role for a resource group, allowing you to make changes to that resource group. Azure Policy focuses on resource properties during deployment and for already existing resources. Azure Policy controls properties such as the types or locations of resources. Unlike RBAC, Azure Policy is a default allow and explicit deny system.

The Azure Activity Log provides insight into subscription-level events that have occurred in Azure. This includes a range of data, from Azure Resource Manager operational data to updates on Service Health events. The Activity Log was previously known as Audit Logs or Operational Logs, since the Administrative category reports control-plane events for your subscriptions.

Use the Activity Log, to determine the what, who, and when for any write operations (PUT, POST, DELETE) taken on the resources in your subscription. You can also understand the status of the operation and other relevant properties.

The Activity Log does not include read (GET) operations or operations for resources that use the Classic/RDFE model.

There is a single Activity Log for each Azure subscription. It provides data about the operations on a resource from the outside (the "control plane"). Diagnostic Logs are emitted by a resource and provide information about the operation of that resource (the "data plane"). You must enable diagnostic settings for each resource.

You attempt to create several managed Microsoft SQL Server instances in an Azure environment and receive a message that you must increase your Azure Subscription Limits.

What should you do to increase the limits?

Answers


Explanation (click to expand)

If you want to raise the limit or quota above the default limit, open an online customer support request at no charge.

Free Trial subscriptions aren't eligible for limit or quota increases. If you have a Free Trial subscription, you can upgrade to a Pay-As-You-Go subscription. For more information, see Upgrade your Azure Free Trial subscription to a Pay-As-You-Go subscription and the Free Trial subscription FAQ.

Quotas for resources in Azure resource groups are per-region accessible by your subscription, not per-subscription as the service management quotas are. Let's use vCPU quotas as an example. To request a quota increase with support for vCPUs, you must decide how many vCPUs you want to use in which regions. You then make a specific request for Azure resource group vCPU quotas for the amounts and regions that you want. If you need to use 30 vCPUs in West Europe to run your application there, you specifically request 30 vCPUs in West Europe. Your vCPU quota isn't increased in any other region--only West Europe has the 30-vCPU quota.

As a result, decide what your Azure resource group quotas must be for your workload in any one region. Then request that amount in each region into which you want to deploy. For help in how to determine your current quotas for specific regions, see Troubleshoot deployment issues.

Question 49

You need to identify the type of failure for which an Azure availability zone can be used to protect access to Azure services.

What should you identify?

Answers


Explanation (click to expand)

Availability Zones is a high-availability offering that protects your applications and data from datacenter failures. Availability Zones are unique physical locations within an Azure region. Each zone is made up of one or more datacenters equipped with independent power, cooling, and networking. To ensure resiliency, there's a minimum of three separate zones in all enabled regions. The physical separation of Availability Zones within a region protects applications and data from datacenter failures. Zone-redundant services replicate your applications and data across Availability Zones to protect from single-points-of-failure. With Availability Zones, Azure offers industry best 99.99% VM uptime SLA. The full Azure SLA explains the guaranteed availability of Azure as a whole.

An Availability Zone in an Azure region is a combination of a fault domain and an update domain. For example, if you create three or more VMs across three zones in an Azure region, your VMs are effectively distributed across three fault domains and three update domains. The Azure platform recognizes this distribution across update domains to make sure that VMs in different zones are not updated at the same time.

Build high-availability into your application architecture by co-locating your compute, storage, networking, and data resources within a zone and replicating in other zones. Azure services that support Availability Zones fall into two categories:

Zonal services – you pin the resource to a specific zone (for example, virtual machines, managed disks, Standard IP addresses), or

Zone-redundant services – platform replicates automatically across zones (for example, zone-redundant storage, SQL Database).

Solution: You modify a DDoS protection plan.

Does this meet the goal?

Answers


Explanation (click to expand)

You open a port, or create an endpoint, to a virtual machine (VM) in Azure by creating a network filter on a subnet or a VM network interface. You place these filters, which control both inbound and outbound traffic, on a network security group attached to the resource that receives the traffic.

The example in this article demonstrates how to create a network filter that uses the standard TCP port 80 (it's assumed you've already started the appropriate services and opened any OS firewall rules on the VM).

After you've created a VM that's configured to serve web requests on the standard TCP port 80, you can:

1. Create a network security group.

2. Create an inbound security rule allowing traffic and assign values to the following settings:

a. Destination port ranges: 80.

b. Source port ranges: * (allows any source port).

c. Priority value: Enter a value that is less than 65,500 and higher in priority than the default catch-all deny inbound rule.

Associate the network security group with the VM network interface or subnet.

Your company plans to deploy several web servers and several database servers to Azure.

You need to recommend an Azure solution to limit the types of connections from the web servers to the database servers.

What should you include in the recommendation?

Answers


Explanation (click to expand)

You can filter network traffic to and from Azure resources in an Azure virtual network with a network security group. A network security group contains security rules that allow or deny inbound network traffic to, or outbound network traffic from, several types of Azure resources. To learn about which Azure resources can be deployed into a virtual network and have network security groups associated to them, see Virtual network integration for Azure services. For each rule, you can specify source and destination, port, and protocol.

Network security group security rules are evaluated by priority using the 5-tuple information (source, source port, destination, destination port, and protocol) to allow or deny the traffic. A flow record is created for existing connections. Communication is allowed or denied based on the connection state of the flow record. The flow record allows a network security group to be stateful. If you specify an outbound security rule to any address over port 80, for example, it's not necessary to specify an inbound security rule for the response to the outbound traffic. You only need to specify an inbound security rule if communication is initiated externally. The opposite is also true. If inbound traffic is allowed over a port, it's not necessary to specify an outbound security rule to respond to traffic over the port. Existing connections may not be interrupted when you remove a security rule that enabled the flow. Traffic flows are interrupted when connections are stopped and no traffic is flowing in either direction, for at least a few minutes.

Explanation (click to expand)

Authentication is the process of determining whether someone or something is, in fact, who or what it declares itself to be. Authentication technology provides access control for systems by checking to see if a user's credentials match the credentials in a database of authorized users or in a data authentication server.

Users are usually identified with a user ID, and authentication is accomplished when the user provides a credential, for example a password, that matches with that user ID. Most users are most familiar with using a password, which, as a piece of information that should be known only to the user, is called a knowledge authentication factor.

Authorization is a security mechanism used to determine user/client privileges or access levels related to system resources, including computer programs, files, services, data and application features. Authorization is normally preceded by authentication for user identity verification. System administrators (SA) are typically assigned permission levels covering all system and user resources.

During authorization, a system verifies an authenticated user's access rules and either grants or refuses resource access.

Answers


Explanation (click to expand)

A High Availability system is one that is designed to be available 99.999% of the time, or as close to it as possible. Usually this means configuring a failover system that can handle the same workloads as the primary system.

A Fault Tolerant system is extremely similar to HA, but goes one step further by guaranteeing zero downtime. HA still comes with a small portion of downtime, hence the ideal of a perfect HA strategy reaching “five nines” rather than 100% uptime. The time it takes for the intermediary layer, like the load balancer or hypervisor, to detect a problem and restart the VM can add up to minutes or even hours over the course of yearly runtime.

Disaster Recovery goes beyond FT or HA and consists of a complete plan to recover critical business systems and normal operations in the event of a catastrophic disaster like a major weather event (hurricane, flood, tornado, etc), a cyberattack, or any other cause of significant downtime. HA is often a major component of DR, which can also consist of an entirely separate physical infrastructure site with a 1:1 replacement for every critical infrastructure component, or at least as many as required to restore the most essential business functions.

Pass-through authentication - A sign-in method that allows users to use the same password on-premises and in the cloud, but doesn't require the additional infrastructure of a federated environment.

Federation integration - Federation is an optional part of Azure AD Connect and can be used to configure a hybrid environment using an on-premises AD FS infrastructure. It also provides AD FS management capabilities such as certificate renewal and additional AD FS server deployments.

Synchronization - Responsible for creating users, groups, and other objects. As well as, making sure identity information for your on-premises users and groups is matching the cloud. This synchronization also includes password hashes.

Health Monitoring - Azure AD Connect Health can provide robust monitoring and provide a central location in the Azure portal to view this activity.

Question 58

You have an Azure Active Directory (Azure AD) tenant.

All administrators must enter a verification code to access the Azure portal.

You need to ensure that the administrators can access the Azure portal only from your on-premises network.

What should you configure?

Answers


Explanation (click to expand)

The security of two-step verification lies in its layered approach. Compromising multiple authentication factors presents a significant challenge for attackers. Even if an attacker manages to learn the user's password, it is useless without also having possession of the additional authentication method. It works by requiring two or more of the following authentication methods:

Something you know (typically a password).

Something you have (a trusted device that is not easily duplicated, like a phone).

Explanation (click to expand)

Azure Resource Manager is the deployment and management service for Azure. It provides a management layer that enables you to create, update, and delete resources in your Azure subscription. You use management features, like access control, locks, and tags, to secure and organize your resources after deployment.

When a user sends a request from any of the Azure tools, APIs, or SDKs, Resource Manager receives the request. It authenticates and authorizes the request. Resource Manager sends the request to the Azure service, which takes the requested action. Because all requests are handled through the same API, you see consistent results and capabilities in all the different tools.

Terminology:

resource - A manageable item that is available through Azure. Virtual machines, storage accounts, web apps, databases, and virtual networks are examples of resources.

resource group - A container that holds related resources for an Azure solution. The resource group includes those resources that you want to manage as a group. You decide which resources belong in a resource group based on what makes the most sense for your organization.

resource provider - A service that supplies Azure resources. For example, a common resource provider is Microsoft.Compute, which supplies the virtual machine resource. Microsoft.Storage is another common resource provider.

Resource Manager template - A JavaScript Object Notation (JSON) file that defines one or more resources to deploy to a resource group or subscription. The template can be used to deploy the resources consistently and repeatedly.

declarative syntax - Syntax that lets you state "Here is what I intend to create" without having to write the sequence of programming commands to create it. The Resource Manager template is an example of declarative syntax. In the file, you define the properties for the infrastructure to deploy to Azure.

You have an Azure DNS zone named adatum.com.

You need to delegate a subdomain named research.adatum.com to a different DNS server in Azure.

What should you do?

Answers


Explanation (click to expand)

You need to create a name server (NS) record for the zone.

The A Record points your hostname to an IP address. The record A specifies IP address (IPv4) for given host. This is one of the most frequently used records in the DNS Zones.

PTR records are used for the Reverse DNS (Domain Name System) lookup. Using the IP address you can get the associated domain/hostname. An A record should exist for every PTR record. The usage of a reverse DNS setup for a mail server is a good solution.

The SOA means Start Of Authority. The SOA record defines the beginning of the authority DNS zone and specifies the global parameters for the zone. The SOA record has the following structure: "Serial number", "Primary name server (NS)", "DNS admin e-mail", "Refresh Rate", "Retry Rate", "Expire time" and "Default TTL".

The NS records identify the name servers, responsible for your DNS zone. In order to have a valid DNS configuration, the NS records configured in the DNS zone must be exactly the same as these configured as name servers at your domain name provider.

Explanation (click to expand)

Verification methods:

You can choose the verification methods that are available for your users.

When your users enroll their accounts for Azure Multi-Factor Authentication, they choose their preferred verification method from the options that you have enabled. Guidance for the user enrollment process is provided in Set up my account for two-step verification.

Call to phone: Places an automated voice call. The user answers the call and presses # in the phone keypad to authenticate. The phone number is not synchronized to on-premises Active Directory.

Text message to phone: Sends a text message that contains a verification code. The user is prompted to enter the verification code into the sign-in interface. This process is called one-way SMS. Two-way SMS means that the user must text back a particular code. Two-way SMS is deprecated and not supported after November 14, 2018. Users who are configured for two-way SMS are automatically switched to call to phone verification at that time.

Notification through mobile app: Sends a push notification to your phone or registered device. The user views the notification and selects Verify to complete verification. The Microsoft Authenticator app is available for Windows Phone, Android, and iOS.

Verification code from mobile app or hardware token: The Microsoft Authenticator app generates a new OATH verification code every 30 seconds. The user enters the verification code into the sign-in interface. The Microsoft Authenticator app is available for Windows Phone, Android, and iOS.

You need to synchronize the files in Data to an on-premises server named Server1.

Which three actions should you perform? Each correct answer presents part of the solution.

NOTE: Each correct selection is worth one point.

Answers


Explanation (click to expand)

Use Azure File Sync to centralize your organization's file shares in Azure Files, while keeping the flexibility, performance, and compatibility of an on-premises file server. Azure File Sync transforms Windows Server into a quick cache of your Azure file share. You can use any protocol that's available on Windows Server to access your data locally, including SMB, NFS, and FTPS. You can have as many caches as you need across the world.

Step 1: Install the Azure File Sync agent on Server1. The Azure File Sync agent is a downloadable package that enables Windows Server to be synced with an Azure file share.

Step 2: Register Server1. Register Windows Server with Storage Sync Service. Registering your Windows Server with a Storage Sync Service establishes a trust relationship between your server (or cluster) and the Storage Sync Service.

Step 3: Create a sync group and a cloud endpoint. A sync group defines the sync topology for a set of files. Endpoints within a sync group are kept in sync with each other. A sync group must contain one cloud , which represents an Azure file share and one or more server endpoints. A server endpoint represents a path on registered server.

The WARNING state indicates one or more issues in VM's configuration that might lead to backup failures and provides recommended steps to ensure successful backups. Not having the latest VM Agent installed, for example, can cause backups to fail intermittently and falls in this class of issues.

The PASSED state indicates that your VMs configuration is conducive for successful backups and no corrective action needs to be taken.

The CRITICAL state indicates one or more critical issues in the VM's configuration that will lead to backup failures and provides required steps to ensure successful backups. A network issue caused due to an update to the NSG rules of a VM, for example, will fail backups as it prevents the VM from communicating with the Azure Backup service and falls in this class of issues.

Allow gateway transit: Check this box if you have a virtual network gateway attached to this virtual network and want to allow traffic from the peered virtual network to flow through the gateway. For example, this virtual network may be attached to an on-premises network through a virtual network gateway. The gateway can be an ExpressRoute or VPN gateway. Checking this box allows traffic from the peered virtual network to flow through the gateway attached to this virtual network to the on-premises network. If you check this box, the peered virtual network cannot have a gateway configured. The peered virtual network must have the Use remote gateways checkbox checked when setting up the peering from the other virtual network to this virtual network. If you leave this box unchecked (default), traffic from the peered virtual network still flows to this virtual network, but cannot flow through a virtual network gateway attached to this virtual network. If the peering is between a virtual network (Resource Manager) and a virtual network (classic), the gateway must be in the virtual network (Resource Manager).

Question 92

You are troubleshooting a performance issue for an Azure Application Gateway.

You need to compare the total requests to the failed requests during the past six hours.

What should you use?

Answers


Explanation (click to expand)

Azure Application Gateway is a web traffic load balancer that enables you to manage traffic to your web applications. Traditional load balancers operate at the transport layer (OSI layer 4 - TCP and UDP) and route traffic based on source IP address and port, to a destination IP address and port.

With Application Gateway, you can make routing decisions based on additional attributes of an HTTP request, such as URI path or host headers. For example, you can route traffic based on the incoming URL. So if /images is in the incoming URL, you can route traffic to a specific set of servers (known as a pool) configured for images. If /video is in the URL, that traffic is routed to another pool that's optimized for videos.

This type of routing is known as application layer (OSI layer 7) load balancing. Azure Application Gateway can do URL-based routing and more.

By using Azure Application Gateway, you can monitor resources in the following ways:

Back-end health: Application Gateway provides the capability to monitor the health of the servers in the back-end pools through the Azure portal and through PowerShell. You can also find the health of the back-end pools through the performance diagnostic logs.

Logs: Logs allow for performance, access, and other data to be saved or consumed from a resource for monitoring purposes.

Metrics: Application Gateway has several metrics which help you verify that your system is performing as expected.

Question 93

You have two subscriptions named Subscription1 and Subscription2. Each subscription is associated to a different Azure AD tenant.

Subscription1 contains a virtual network named VNet1. VNet1 contains an Azure virtual machine named VM1 and has an IP address space of 10.0.0.0/16.

Subscription2 contains a virtual network named VNet2. VNet2 contains an Azure virtual machine named VM2 and has an IP address space of 10.10.0.0/24.

You need to connect VNet1 to VNet2.

What should you do first?

Answers


Explanation (click to expand)

The virtual networks can be in the same or different regions, and from the same or different subscriptions. When connecting VNets from different subscriptions, the subscriptions do not need to be associated with the same Active Directory tenant.

Configuring a VNet-to-VNet connection is a good way to easily connect VNets. Connecting a virtual network to another virtual network using the VNet-to-VNet connection type (VNet2VNet) is similar to creating a Site-to-Site IPsec connection to an on-premises location. Both connectivity types use a VPN gateway to provide a secure tunnel using IPsec/IKE, and both function the same way when communicating.

The local network gateway for each VNet treats the other VNet as a local site. This lets you specify additional address space for the local network gateway in order to route traffic.

Answers


Explanation (click to expand)

All Azure resources are created in an Azure region and subscription. A resource can only be created in a virtual network that exists in the same region and subscription as the resource. You can however, connect virtual networks that exist in different subscriptions and regions. For more information, see connectivity. When deciding which region(s) to deploy resources in, consider where consumers of the resources are physically located:

Consumers of resources typically want the lowest network latency to their resources. To determine relative latencies between a specified location and Azure regions, see View relative latencies.

Do you have data residency, sovereignty, compliance, or resiliency requirements? If so, choosing the region that aligns to the requirements is critical.

Do you require resiliency across Azure Availability Zones within the same Azure region for the resources you deploy? You can deploy resources, such as virtual machines (VM) to different availability zones within the same virtual network. Not all Azure regions support availability zones however.

Answers


Explanation (click to expand)

You can connect virtual networks to each other with virtual network peering. These virtual networks can be in the same region or different regions (also known as Global VNet peering). Once virtual networks are peered, resources in both virtual networks are able to communicate with each other, with the same latency and bandwidth as if the resources were in the same virtual network.

NOTE: Each correct selection is worth one point.

Answers


Explanation (click to expand)

A VPN gateway is used when creating a VPN connection to your on-premises network.

Route-based VPN devices use any-to-any (wildcard) traffic selectors, and let routing/forwarding tables direct traffic to different IPsec tunnels. It is typically built on router platforms where each IPsec tunnel is modeled as a network interface or VTI (virtual tunnel interface).

Policy-based VPN devices use the combinations of prefixes from both networks to define how traffic is encrypted/decrypted through IPsec tunnels. It is typically built on firewall devices that perform packet filtering. IPsec tunnel encryption and decryption are added to the packet filtering and processing engine.

Point-to-Site connections do not require a VPN device or a public-facing IP address.

Resource group - A container that holds related resources for an Azure solution. The resource group includes those resources that you want to manage as a group. You decide which resources belong in a resource group based on what makes the most sense for your organization.

There are some important factors to consider when defining your resource group:

* A resource group can contain resources that are located in different regions.

* All the resources in your group should share the same lifecycle. You deploy, update, and delete them together. If one resource, such as a database server, needs to exist on a different deployment cycle it should be in another resource group.

* Each resource can only exist in one resource group.

* You can add or remove a resource to a resource group at any time.

* You can move a resource from one resource group to another group.

* A resource group can be used to scope access control for administrative actions.

* A resource can interact with resources in other resource groups. This interaction is common when the two resources are related but don't share the same lifecycle (for example, web apps connecting to a database).

You need to ensure that you can connect Client1 to VNet2.

What should you do?

Answers


Explanation (click to expand)

P2S VPN routing behavior is dependent on the client OS, the protocol used for the VPN connection, and how the virtual networks (VNets) are connected to each other.

Azure currently supports two protocols for remote access, IKEv2 and SSTP. IKEv2 is supported on many client operating systems including Windows, Linux, MacOS, Android, and iOS. SSTP is only supported on Windows. If you make a change to the topology of your network and have Windows VPN clients, the VPN client package for Windows clients must be downloaded and installed again in order for the changes to be applied to the client.

Your company registers a domain name of contoso.com.

You create an Azure DNS zone named contoso.com, and then you add an A record to the zone for a host named www that has an IP address of 131.107.1.10.

You discover that Internet hosts are unable to resolve www.contoso.com to the 131.107.1.10 IP address.

You need to resolve the name resolution issue.

Solution: You create a PTR record for www in the contoso.com zone.

Does this meet the goal?

Answers


Explanation (click to expand)

The Domain Name System is a hierarchy of domains. The hierarchy starts from the 'root' domain, whose name is simply '.'. Below this come top-level domains, such as 'com', 'net', 'org', 'uk' or 'jp'. Below these are second-level domains, such as 'org.uk' or 'co.jp'. The domains in the DNS hierarchy are globally distributed, hosted by DNS name servers around the world.

A domain name registrar is an organization that allows you to purchase a domain name, such as 'contoso.com'. Purchasing a domain name gives you the right to control the DNS hierarchy under that name, for example allowing you to direct the name www.contoso.com to your company web site. The registrar may host the domain in its own name servers on your behalf, or allow you to specify alternative name servers.

Azure DNS provides a globally distributed, high-availability name server infrastructure, which you can use to host your domain. By hosting your domains in Azure DNS, you can manage your DNS records with the same credentials, APIs, tools, billing, and support as your other Azure services.

The NS record set at the zone apex is automatically created with each DNS zone. It contains the names of the Azure DNS name servers assigned to the zone. You can add additional name servers to this NS record set, to support co-hosting domains with more than one DNS provider. You can also modify the TTL and metadata for this record set. However, you cannot remove or modify the pre-populated Azure DNS name servers.

Modify the Name Server (NS) record.
