HPE Aruba Certified Mobility Professional (ACMP) — Question 90

AOS-Switch runs IGMP in data-driven mode. What behavior does it exhibit?

Answer options

• A. It drops multicasts destined to groups that have no members
• B. It preempts the querier role even if another device has higher priority
• C. It floods multicasts on all ports in the VLAN if the group has at least one member
• D. It disables automatic fast leave on ports that connect to a single device

Correct answer: A

Explanation

The correct answer is A because in data-driven mode, AOS-Switch only forwards multicast traffic to ports with active members, thus dropping traffic for groups without members. Option B is incorrect as it refers to the querier role which isn't relevant in data-driven mode. Option C is wrong because flooding occurs only if there are no members, and option D is unrelated to the data-driven operational mode.
