What is the purpose of a Test DR exercise in NetApp practice?

• A. Validate DR readiness and ensure SnapMirror and SnapVault configurations function properly
• B. To install a new feature
• C. To upgrade hardware firmware
• D. To test network encryption only

Answer: (A)

A Test DR exercise is about confirming disaster recovery readiness by validating that replication and recovery workflows work as intended. In NetApp practice, this means checking that data replication using SnapMirror and backups via SnapVault are healthy, up-to-date, and capable of being brought online at the DR site when needed. It also verifies that failover procedures can be executed without violating the defined recovery objectives, and that failback is possible once the primary site is restored. Beyond just the technical hookups, it tests the runbook, any automation, network paths, and application connectivity to ensure the entire DR process can be performed smoothly under real conditions. This reduces risk and downtime in a real disaster.

Installing a new feature, upgrading hardware firmware, or testing network encryption only do not capture this broader goal of validating the recovery process and data integrity across sites.
