Which steps are essential to validate HA failover readiness?

• A. Plan HA Topology, Test Failover, Verify Multi-Pathing, and Document Procedures
• B. Do Not Test Failover
• C. Only Test After a Year
• D. Disable Failover

Answer: (A)

Ensuring HA failover readiness means taking a practical, end-to-end approach that covers design, testing, path reliability, and documented guidance. You start by planning the HA topology to define which nodes participate, how interconnects provide redundancy, how failover will occur, and what resources must failover together. Then you validate by performing controlled failover tests to confirm the system can switch to the standby, maintain data integrity, meet expected recovery times, and resume service smoothly. Next, you verify multi-pathing to guarantee there are redundant paths from hosts to storage, that path failover happens automatically when a link fails, and that path policies align with performance and availability goals. Finally, you document procedures so operators have clear runbooks for performing failovers, validating success, and recovering if something goes wrong, including rollback steps and contact information. Taken together, this approach reduces risk, ensures predictable behavior during outages, and provides repeatable, auditable evidence of readiness. Not testing failover, delaying tests, or disabling failover would leave gaps and increase risk during a real outage.
