Azure Payroll System Business Continuity Solution
Question
You plan to deploy a payroll system to Azure. The payroll system will use Azure virtual machines that run SUSE Linux Enterprise Server and Windows.
You need to recommend a business continuity solution for the payroll system. The solution must meet the following requirements:
-> Minimize costs.
-> Provide business continuity if an Azure region fails.
-> Provide a recovery time objective (RTO) of 120 minutes.
-> Provide a recovery point objective (RPO) of five minutes.
What should you include in the recommendation?

A. B. C. D.C
If your storage account has GRS enabled, then your data is durable even in the case of a complete regional outage or a disaster in which the primary region isn't recoverable.
Note: The recovery time objective (RTO) is the targeted duration of time and a service level within which a business process must be restored after a disaster (or disruption) in order to avoid unacceptable consequences associated with a break in business continuity.
Incorrect Answers:
B: Azure Site Recovery would not protect against an Azure region failure.
Azure Site Recovery guarantees a two-hour Recovery Time Objective.
https://docs.microsoft.com/en-us/azure/storage/common/storage-redundancy-grs https://azure.microsoft.com/en-us/support/legal/sla/site-recovery/v1_0/Based on the requirements provided, the recommended solution should provide business continuity in case of an Azure region failure, while minimizing costs and adhering to the given recovery time and point objectives.
Option A: Microsoft System Center Data Protection Manager (DPM) Microsoft System Center Data Protection Manager (DPM) is a backup and recovery solution that provides protection for Windows-based workloads. However, DPM does not offer disaster recovery capabilities or support Linux-based workloads, so it is not a suitable solution for this scenario.
Option B: Azure Site Recovery Azure Site Recovery is a disaster recovery solution that provides automated replication and failover for virtual machines and physical servers. It is a cost-effective solution that can help to minimize downtime in case of an Azure region failure. Azure Site Recovery supports both Linux and Windows-based workloads and can provide a recovery time objective (RTO) of as low as 15 minutes, which is well within the given requirement of 120 minutes. Azure Site Recovery also supports a recovery point objective (RPO) of as low as 5 minutes, which meets the given requirement. Therefore, Option B is the recommended solution.
Option C: Unmanaged disks that use geo-redundant storage (GRS) Unmanaged disks that use geo-redundant storage (GRS) can provide geo-replication of data to a secondary Azure region, which can help to ensure business continuity in case of an Azure region failure. However, this solution does not provide disaster recovery capabilities for virtual machines, and it does not offer automated failover or replication. Additionally, unmanaged disks require more manual management and monitoring, which can increase operational costs. Therefore, Option C is not the recommended solution for this scenario.
Option D: Azure Backup Azure Backup is a backup and recovery solution that can protect data stored in virtual machines, physical servers, and cloud services. However, Azure Backup does not offer disaster recovery capabilities or support for automated failover, which are necessary to meet the given requirements. Therefore, Option D is not the recommended solution for this scenario.
In conclusion, Azure Site Recovery is the recommended solution for this scenario. It provides disaster recovery capabilities for both Linux and Windows-based virtual machines, supports automated replication and failover, and can meet the given recovery time and point objectives while minimizing costs.
