HPE Aruba Certified Professional (ACP) – SD-WAN — Question 86

You have enabled PIM and IGMP querier function on a pair of VSX switches, but noticed that the secondary switch is always elected as the querier for all VLANs. What could explain this behavior?

Answer options

• A. The primary switch has a higher MAC address.
• B. The primary switch has a lower uptime.
• C. The secondary switch has a higher VRRP priority.
• D. The secondary switch has a lower IP address.

Correct answer: D

Explanation

The correct answer is D, as the IGMP querier election process favors the switch with the lowest IP address. The other options do not impact the querier selection process, since MAC address, uptime, and VRRP priority are not factors in determining which switch becomes the querier.
