Which option describes disaster recovery testing?

• A. SLA renegotiation.
• B. Backups verification only.
• C. Network topology redesign.
• D. Testing to verify disaster recovery procedures work under expected conditions.

Answer: (D)

Disaster recovery testing is about validating that the documented recovery procedures actually work when an outage occurs. It involves running through the DR plan under realistic incident conditions to confirm that the steps can be executed correctly, systems can fail over or be restored, and critical services come back within the defined time targets (recovery time objective and recovery point objective). This end-to-end exercise ensures the organization can recover operations as intended when a real disaster hits.

Backups verification focuses on data copies and their restorability, but by itself it doesn’t prove that the full recovery workflow, failover processes, and coordination between teams will work under actual outage conditions. SLA renegotiation is about service level terms, not testing the recovery procedures. Network topology redesign relates to changing infrastructure design, not validating the DR plan’s execution.
