Microsoft Certified: Azure Solutions Architect ExpertDesign business continuity solutionsMedium
A global manufacturing company uses Azure Virtual Machines to host its critical ERP system. The company requires a recovery point objective (RPO) of 4 hours and a recovery time objective (RTO) of 8 hours. The solution must provide disaster recovery capabilities to a secondary Azure region. Which Azure service should be used to meet these requirements?
- AAzure Backup for daily snapshots
- BAzure Site Recovery with replication policies
- CAzure Files with geo-redundant storage
- DAzure Traffic Manager with active-passive setup
Show answer & explanationAnswer & explanation
Correct answer: B. Azure Site Recovery with replication policies
Azure Site Recovery (ASR) is specifically designed for disaster recovery of virtual machines, supporting replication to another region and enabling RPO/RTO configuration to meet business continuity requirements.
Why the other options are wrong
- A. Azure Backup provides backups but is not primarily designed for continuous replication and rapid failover for disaster recovery scenarios.
- C. Azure Files with geo-redundant storage is for file shares, not for entire virtual machine disaster recovery.
- D. Azure Traffic Manager is a DNS-based traffic load balancer, not a disaster recovery solution for VM replication and failover.
Azure Site Recovery (ASR)
A disaster recovery service that orchestrates replication, failover, and recovery of workloads running on physical and virtual machines.
- Provides business continuity by replicating workloads to a secondary location.
- Supports various RPO/RTO targets.
- Can be used for on-premises to Azure, Azure to Azure, and VMware/Hyper-V to Azure scenarios.
Memory trick: Always Recover Systematically: ASR is your Go-To.
