Question 18

You are the IT administrator for an automobile dealership on the west coast of the United States. The dealership wants to take advantage of Microsoft Azure by first moving its website to the cloud. The dealership wants to use the lowest cost solution possible.

Business Requirements

One of the problems the dealership has been facing is website downtime. The dealership typically provides maintenance every Sunday and Wednesday at 2:00 A.M. Eastern Time. However, because the dealership wants to attract customers all over the world, it wants to ensure that the website is always available. During peak seasons, the dealership notices that the website responds slower. The dealership wants this bottleneck eliminated.

Technical Requirements

The website is currently hosted at the dealership's domain registrar. The dealership wants move the site to Azure on Windows Server virtual machines (VMs). Users must be able to use the same domain name to reach the website. The website must be hosted in only one Azure region. The VMs must use a four-gigabyte (GB) solid state drive (SSD). The dealership expects there be less hands-on maintenance and administration once the infrastructure is moved to Azure.





You should add an inbound port rule to the VM. This rule should allow traffic over an HTTP port, which by default is port 80. (For HTTPS, the port is 443.)

You should also add a DNS name label to the VM. This is a host (A) record that resolves to the public IP address assigned to the VM. The public IP address is dynamic by default, and this does not cost any more money. At the domain registrar, you can create a CNAME record that points your website domain name to Azure at [dnsnamelabel].[region].cloudapp.azure.net.

You should not add a VM extension. A VM extension is a small application that provides post deployment tasks. For example, an extension can automatically install anti-virus software whenever a VM is deployed through script.

You should not add an outbound port rule to the VM. The VM should allow all outbound traffic by default.

You should not assign a public static IP address to the VM. This causes the IP address assigned to it to always remain the same. However, this is not necessary and it costs more money. You can use a CNAME record at the domain registrar and a DNS name label in Azure.
