Microsoft Azure Solutions Architect Expert AZ-305 Practice Question

Contoso runs two Windows Server virtual machines (VMs) in the Azure East US region and a business-critical SQL Server VM on a VMware host in its on-premises datacenter. The company has set these disaster-recovery objectives:

  • If East US becomes unavailable, the Azure VMs must start in West US with a recovery point objective (RPO) of no more than 15 minutes and a recovery time objective (RTO) of no more than 2 hours.
  • The on-premises SQL Server VM must be able to fail over to Azure within the same RPO and RTO targets.
  • Administrators must be able to perform failover tests at any time without disrupting production workloads.

You need to recommend a single Azure service or capability that meets all these requirements. Which option should you choose?

  • Read-access geo-redundant storage (RA-GRS) snapshots of the virtual disks

  • Azure Site Recovery replication for both Azure VMs and on-premises VMware VMs

  • Availability Sets for the Azure VMs combined with Azure Traffic Manager failover profiles

  • Azure Backup using a Recovery Services vault configured with geo-redundant storage
