Question 440
A stack's standby control member cannot take over after a failover drill because the new member has incompatible firmware. Which result would best establish that the correction succeeded?
Explanation
Correct Answer
This is an operational test of the required outcome rather than merely proof a setting exists. It checks that control-member version mismatch prevents stable participation in the intended logical stack no longer prevents the service.
Incorrect Answers
This result may validate another network change, but it does not demonstrate recovery from the fault here: control-member version mismatch prevents stable participation in the intended logical stack.
That explanation does not distinguish this option. “A single-member failure leaves all required server VLANs reachable” is an alternative action, but it does not by itself establish the outcome required in this case.
That explanation does not distinguish this option. “Storm counters stabilize and normal unicast forwarding returns without unintended blocked infrastructure links” is an alternative action, but it does not by itself establish the outcome required in this case.
