Microsoft Azure Architect Design (AZ-304) Practice Test

For a system that requires rapid disaster recovery with a maximum RTO of 120 minutes, which solution is best?

1. Azure Backup

2. Azure Site Recovery

3. Microsoft System Center DPM

4. Standard_LRS storage options

The correct answer is: Azure Site Recovery

Selecting Azure Site Recovery as the best solution for achieving a rapid disaster recovery with a maximum Recovery Time Objective (RTO) of 120 minutes makes sense due to its design and features tailored for business continuity. Azure Site Recovery is specifically built for disaster recovery scenarios. It orchestrates the replication of virtual machines and physical servers to a secondary location, which can be in another Azure region or a different cloud provider, ensuring that in the event of an outage, the systems can be quickly failed over to the standby site. This streamlined orchestration allows for quick recovery of workloads, enabling organizations to meet stringent RTO requirements effectively. In comparison, while Azure Backup provides essential backup services and allows for recovery of data, it is not optimized for rapid full-scale disaster recovery. It is more suited for data retention and restoration, which, while important, does not focus specifically on minimizing downtime like Azure Site Recovery does. Microsoft System Center Data Protection Manager (DPM) also offers backup solutions but lacks the automated failover and failback capabilities that Azure Site Recovery provides. DPM is more suited for on-premises environments and has limitations when dealing with large-scale, cloud-based recovery scenarios. Standard_LRS storage options refer to a type of replication for Azure Blob storage and
