HPE Aruba Certified Campus Access Expert (ACAEX) — Question 27

You are proposing new CX 8360 VSX switches to replace a customer’s existing core switches. The customer is concerned about the possibility of a split-brain scenario between the VSX pair.
How is the VSX pair affected when the ISL is down and keepalive is down?

Answer options

• A. The VSX node with lower system-id continues forwarding.
• B. Both VSX nodes will automatically reboot and keep LAG interfaces shutdown.
• C. Both VSX nodes will still forward traffic.
• D. The VSX node with higher uptime continues forwarding.

Correct answer: A

Explanation

The correct answer is A because in a split-brain scenario, the VSX node with the lower system-id takes over forwarding duties to maintain network functionality. Option B is incorrect as the nodes do not reboot in this situation, and option C is wrong because traffic forwarding is not guaranteed for both nodes. Option D is also incorrect since the node with higher uptime does not automatically continue forwarding in the event of a split-brain situation.
