Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 102

A network engineer needs to configure multicast in the network. The implementation will use multiple multicast groups and PIM routers. Which address provides automatic discovery of the best RP for each multicast group?

Answer options

• A. 224.0.0.13
• B. 224.0.0.14
• C. 224.0.1.39
• D. 224.0.1.40

Correct answer: D

Explanation

The correct answer is D, as 224.0.1.40 is the address used for the Auto-RP mechanism, which allows for automatic discovery of the best RP for multicast groups. Options A and B refer to the PIM Hello and Bootstrap messages, while option C is not used for RP discovery.
