HPE Aruba Certified Professional (ACP) – SD-WAN — Question 73

While troubleshooting a scenario in which the customer has created a new VLAN on a primary HPE Aruba Networking CX 8100 VSX switch, only part of the traffic from the connected access switch over a LAG is working.
Which troubleshooting methodology should you use to isolate the problem?

Answer options

• A. Replace the configuration using the previous checkpoint on the primary VSX.
• B. Divide and conquer by rebooting the secondary VSX switch.
• C. Follow the path and check the connectivity from the access to the primary VSX.
• D. Spot the difference by comparing the VSX switch configurations.

Correct answer: D

Explanation

The correct answer is D because comparing the configurations allows you to identify any discrepancies that may be causing the issue with traffic. Option A is incorrect as reverting to a previous checkpoint does not specifically target the issue at hand. Option B is not effective since rebooting the secondary switch does not address potential configuration problems. Option C, while useful, does not directly help in identifying configuration differences which are crucial in this scenario.
