Designing Cisco Enterprise Networks (ENSLD) — Question 307

Which feature is used to optimize WAN bandwidth of IGMP network traffic among WAN Edge routers in the same VPN?

Answer options

• A. IGMPv2
• B. multicast RP
• C. multicast-replicator
• D. multicast service routes

Correct answer: C

Explanation

The multicast-replicator is designed specifically to optimize WAN bandwidth by efficiently handling multicast traffic among WAN Edge routers in the same VPN. The other options, such as IGMPv2 and multicast RP, do not focus on bandwidth optimization, while multicast service routes refer to routing rather than bandwidth efficiency.
