Refer to the exhibit.
An administrator created a backplane stack with the plug-and-play method and did not alter the default backplane stacking settings. Later, two backplane stacking links failed as shown in the exhibit. The network administrator then restored the failed links.
When the stack is reformed, which switches become commander and standby?
When a stack re-forms after a split, the commander and standby in the active fragment retain their roles when the fragments are reconnected. Member 4, in this case, was the commander of the active fragment, and Member 5 was the standby. As per the typical behavior of stacking protocols like those from Cisco, upon restoring the failed links, the switches in the inactive fragment reboot and assume their new roles based on the active fragment's commander and standby. Therefore, Member 4 remains the commander, and Member 5 remains the standby.
Correct answer is A. When the two fragments are reconnected, the commander and standby of the active fragment retain those roles for the recombined stack. If the original commander was not in that fragment, then the stack will have a new commander when the stack is reformed. The switches in the Inactive fragment reboot and assume their new roles in the stack.
A is correct.
A is the right one.
