HPE Aruba Certified Professional (ACP) – SD-WAN — Question 70

Your customer’s network experiencing a severe broadcast storm, which you suspect is caused by a loop somewhere at the network edge. You start by disconnecting all the switch downlinks from the aggregation switch, checking CPU utilization, and then reconnecting the downlinks one at a time.
Which troubleshooting methodology does this exemplify?

Answer options

• A. Top-down/Bottom-up
• B. Replace configuration
• C. Spot the difference
• D. Divide and conquer

Correct answer: D

Explanation

The correct answer is 'Divide and conquer' because this method involves isolating different components to identify the source of the problem. The other options do not appropriately describe the systematic approach of testing each downlink individually to locate the issue.
