Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 824

An engineer adds a new switch to a Cisco StackWise stack. The switch that was active before the switch was added is elected as the active switch again. Which action does the active switch take?

Answer options

• A. It suspends traffic forwarding until the new switch is updated with the current running configuration of the stack.
• B. It checks the IOS and running configuration of the new switch and updates them if necessary to match the other switches in the stack.
• C. It removes any Layer 3 configuration on the new switch to maintain normal Layer 2 functionality on the stack.
• D. It clears the MAC table of the stack and relearns the attached devices.

Correct answer: B

Explanation

The correct answer is B because the active switch must ensure that the new switch's IOS and configuration are consistent with the existing stack to maintain functionality. Options A, C, and D are incorrect as they do not address the necessary synchronization of configurations between the switches in the stack.
