Designing Cisco Enterprise Networks (ENSLD) — Question 12

An engineer is working for a large cable TV provider that requires multiple sources streaming video on different channels using multicast with no rendezvous point.
Which multicast protocol meets these requirements?

Answer options

• A. PIM-SM
• B. PIM-SSM
• C. any-source multicast
• D. BIDIR-PIM

Correct answer: B

Explanation

PIM-SSM (Protocol Independent Multicast - Source Specific Multicast) is designed for scenarios where the receivers know the specific source addresses and requires no rendezvous point. In contrast, PIM-SM (Sparse Mode) and BIDIR-PIM (Bidirectional PIM) involve rendezvous points, and any-source multicast does not limit sources to specific ones, which does not meet the given requirements.
