HPE Aruba Certified Network Security Expert (ACNSX) — Question 83

An administrator is implementing a multicast solution in a multi-VLAN network. Which statement is true about the configuration of the switches in the network?

Answer options

• A. IGMP snooping must be enabled on all interfaces on a switch to intelligently forward traffic
• B. IGMP requires join and leave messages to graft and prune multicast streams between switches
• C. IGMP must be enabled on all routed interfaces where multicast traffic will traverse
• D. IGMP must be enabled on all interfaces where multicast sources and receivers are connected

Correct answer: D

Explanation

The correct answer, D, is accurate because IGMP must be enabled on the interfaces where devices that send and receive multicast traffic are connected to ensure proper communication. Options A and C are incorrect as they misstate the requirements for IGMP snooping and routed interfaces, respectively. Option B, while true about IGMP's function, does not address the specific configuration requirement for interfaces.
