Single answerYou are an Azure Administrator for a large retail company. You have multiple Azure VMs running in the East US region for a mission-critical workload. Your company mandates a disaster recovery solution that replicates these VMs to the West US region for failover in the event of a regional outage. Which step must you perform first to enable replication for these VMs using Azure Site Recovery?
- A
Create a Recovery Services vault in the West US region to store replication data
- B
Install the Microsoft Azure Recovery Services (MARS) agent on each Azure VM
- C
Configure failover policies in the West US region
- D
Create an automation runbook to test failover processes
Show answer and explanation
Correct answer: A
Explanation
Before configuring Azure Site Recovery for Azure VMs, you must have a Recovery Services vault in the region you intend to replicate to. Creating the vault is the first step to set up and manage replication, recovery points, and failover processes.
- A. Correct.
A Recovery Services vault in the target region (West US) is required first to store and manage replication data for Azure Site Recovery. You cannot enable replication without a vault in place.
- B. Incorrect.
The MARS agent is typically used for physical or on-premises servers, or for backups, not for Azure VM to Azure VM replication, so it is not the correct first step.
- C. Incorrect.
While configuring failover policies is important, it occurs after creating the vault and enabling replication settings.
- D. Incorrect.
Automation runbooks for testing failover are useful, but they are not the first requirement for enabling replication.
