HPE7-A01 Exam - Topic 6 Question 45 Discussion

Actual exam question for HP's HPE7-A01 exam

Question #: 45
Topic #: 6

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.

A is definitely wrong, it’s all about the lower ID.

Wait, so the MAC can change just like that?

I vaguely remember that during the initial configuration, the system MAC is assigned based on the VSX ID, but I’m not clear on how that affects replacements.

I feel like configuring a virtual MAC on the Primary VSX node was mentioned in our study materials, but I’m not confident about when to do it.

I think I practiced a question where the MAC address was selected from the node with the lower ID, but I can't recall the exact details.

I remember something about how the system MAC is assigned based on the VSX ID, but I'm not sure if it's fixed or dynamic.

The key here is understanding the VSX behavior when the primary node is replaced. Option B about configuring the vMAC on the primary node seems like the most straightforward approach to retain the system MAC address. I'll focus on that as my strategy for this question.

I'm a bit confused about the specifics of VSX and how the system MAC is managed. I'll need to review the Aruba CX documentation to make sure I have a solid understanding of the VSX functionality before attempting to answer this question.

Based on the options provided, it looks like I need to focus on how the VSX system MAC is assigned and how it is retained after a hardware replacement. I'll need to carefully consider the differences between the answer choices.

Okay, let me think this through. The key is understanding how VSX handles the system MAC address when the primary node is replaced. I'll need to review the VSX configuration options to determine the best approach.

Wait, we're talking about MAC addresses? I thought this was a question about how to keep my coffee warm during the exam. Clearly, I need to start paying more attention in class.

C) Higher ID, eh? Guess the big cheese gets to keep the fancy MAC. Reminds me of that time I tried to upgrade my router and ended up with a new IP address. Not fun.

I see both points, but I think option A could also work well if we want the MAC address to be selected from a node with a lower ID.

D) Ah, that makes sense. The system-mac is assigned during the initial VSX configuration, so it should be consistent even after a hardware replacement.

B) seems like the best option to retain the MAC address after replacing the Primary VSX node. No one wants to deal with network disruptions due to a MAC change.
