JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing (2023) — Question 34

You have an IPv4 multicast network configured as PIM-SM.
What must be done before replacing your static RP with auto-RP?

Answer options

• A. Enable sparse-dense mode on each of the routers in the network.
• B. Configure auto-RP domains on each router in the network.
• C. Configure each router in the network as a candidate BSR.
• D. Enable each router in the network to forward multicast packets.

Correct answer: A

Explanation

The correct answer is A because enabling sparse-dense mode is necessary for routers to handle both sparse and dense mode multicast traffic. Options B and C are incorrect as configuring auto-RP domains and candidate BSRs are not prerequisites for replacing a static RP with auto-RP. Option D is also not a requirement for this transition.
