HP Exam HPE7-A01 Topic 3 Question 14 Discussion

Actual exam question for HP's HPE7-A01 exam

Question #: 14
Topic #: 3

Your customer currently has Iwo (2) 5406 modular switches with MSTP configured as their core switches. You are proposing a new solution. What would you explain regarding the Aruba CX VSX switch pair when the Primary VSX node is replaced and the system MAC is replaced?

AVSX will select the MAC address from a node that is the lower ID.

BConfigure vMAC on the Primary VSX node under VSX to retain MAC after hardware replacement.

CVSX will select the MAC address from a node that is a higher ID.

DDuring the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID.

Show Suggested Answer

Suggested Answer: D

The system-mac command is used to configure a fixed MAC address for the VSX system. This MAC address is used as the source MAC address for all routed traffic from the VSX node.The system-mac command is highly recommended for preventing traffic disruptions when the primary VSX switch restores after the secondary VSX switch, such as during a primary switch hardware replacement or a power outage2. During the initial VSX configuration, the system-mac is assigned with a fixed MAC based on VSX ID.The system-mac command can be used to change this default MAC address if needed2. Therefore, answer D is correct.

I'm leaning towards option D, assigning a fixed MAC based on VSX ID during initial configuration.

Because configuring vMAC on the Primary VSX node will help retain MAC after hardware replacement.

Actually, I think option A is correct because VSX will select MAC from a node with lower ID.

But wouldn't it be safer to configure vMAC on the Primary VSX node to retain MAC after replacement?

VSX selecting the MAC address from a node with a lower ID, as mentioned in option A, seems like a straightforward approach.

Haha, good one! But I think you might be on to something there. The longer answers tend to have more details, which is usually a good sign.

Hold up, guys. Aren't we forgetting the golden rule of certification exams? 'When in doubt, choose the longest answer!' So I'm going with B.

Hmm, I'm not so sure. I was thinking the correct answer might be D, where the system MAC is assigned based on the VSX ID during initial configuration.

I think the correct answer is B. When the primary VSX node is replaced, we need to configure the vMAC on the new primary node to retain the system MAC address.

Yeah, I agree. The question is testing our knowledge of VSX behavior, which is an important concept for Aruba CX switches.

This question seems pretty straightforward to me. The key is understanding how VSX handles the system MAC address when the primary node is replaced.
