CCDE: Cisco Certified Design Expert (Practical) — Question 117

Which architecture does not require an explicit multicast signaling protocol, such as PIM or P2MP, to signal the multicast state hop-by-hop, but instead uses a link state protocol to advertise the multicast forwarding state?

Answer options

• A. Bi-Directional Implicit Replication
• B. Bit Indexed Explicit Replication
• C. Binary Intermediate Enhanced Routing
• D. Binary Indexed Explicit Routing

Correct answer: B

Explanation

The correct answer, Bit Indexed Explicit Replication, utilizes a link state protocol to manage multicast forwarding without requiring explicit multicast signaling. In contrast, the other options either rely on explicit protocols or do not align with the characteristics of link state protocols.
