HPE Aruba Certified Campus Access Expert (ACAEX) — Question 38

Your customer currently has two (2) 5406 modular switches with MSTP configured as their core switches. You are proposing a new solution.

What would you explain regarding the AOS-CX VSX switch pair when the Primary VSX node is replaced and the system MAC is replaced?

Answer options

• A. Configure vMAC on the Primary VSX node under VSX to retain MAC after hardware replacement.
• B. During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID.
• C. VSX will select the MAC address from a node that is a higher ID.
• D. VSX will select the MAC address from a node that is the lower ID.

Correct answer: A

Explanation

The correct answer is A because configuring vMAC allows the Primary VSX node to maintain its MAC address even after a hardware replacement. Option B is incorrect as the system MAC is not fixed but rather can change under certain configurations. Options C and D are also incorrect because VSX does not select MAC addresses based on node IDs; it relies on the vMAC configuration to ensure continuity.
