HPE Aruba Certified Professional (ACP) – SD-WAN — Question 107

You recently made a configuration change on a switch, and shortly afterward, you noticed a spike in CPU utilization in the NAE dashboard. You are concerned that the high CPU could be affecting users. What should you do to restore services as quickly as possible?

Answer options

• A. Reboot the switch.
• B. Pause NAE monitoring.
• C. Revert the change.
• D. Disable debug logging.

Correct answer: C

Explanation

The correct option is C, as reverting the change will eliminate the configuration that likely caused the CPU spike. Rebooting the switch (A) might temporarily address the issue but won't resolve the underlying cause. Pausing NAE monitoring (B) does not address CPU utilization and might lead to missing critical alerts. Disabling debug logging (D) can help reduce CPU usage but may not be sufficient to restore service quickly.
