Deploying Cisco Service Provider Advanced Routing (SPADVROUTE, legacy) — Question 3

Which multicast routing protocol is most optimal for supporting many-to-many multicast applications?

Answer options

• A. PIM-SM
• B. PIM-BIDIR
• C. MP-BGP
• D. DVMRP
• E. MSDP

Correct answer: B

Explanation

PIM-BIDIR is optimal for many-to-many multicast applications as it allows for efficient shared tree usage, enabling multiple senders and receivers to join the same multicast group. In contrast, PIM-SM is primarily designed for one-to-many scenarios, while MP-BGP, DVMRP, and MSDP do not provide the same level of support for many-to-many multicast communications.
