If the running, working, and certified directories of CMMA and CMMB are the same, what happens on a reload?

• A. The system will display a warning but continue to operate as before.
• B. All services will be interrupted while both CMMA and CMMB restart.
• C. The failover will occur but service will be temporarily degraded.
• D. A reload command will reboot CMMA and fail over to CMMB, CMMB will take over as primary without loss of service.

Answer: (D)

When CMMA and CMMB share the same running, working, and certified directories, the standby is already in sync and ready to take over. Rebooting CMMA triggers a failover to CMMB, which steps up as the primary without any service loss because its state matches the active configuration. The identical directories mean there’s no mismatch to resolve, so the switchover is seamless. If the directories weren’t in sync, you’d expect potential interruptions or mismatches, but with them identical, the transition is smooth and transparent to users.
