AZ104-Q: choose regional disaster recovery
A business requires a VM workload to be replicated to a secondary region and needs an orchestrated failover during a regional outage. Which service is designed for this requirement?
- A) Azure Backup only.
- B) Blob versioning.
- C) An NSG.
- D) Azure Site Recovery. ✓
Answer: D. Azure Site Recovery provides replication and failover orchestration for disaster-recovery scenarios. Backup provides recoverable point-in-time copies but is not the same as active DR replication/failover.
Why not the others: Versioning and NSGs solve different problems. Backup alone does not meet the stated failover requirement.
