Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 53

Which statement about multicast RPs is true?

Answer options

• A. RPs are required only when using protocol independent multicast dense mode.
• B. RPs are required for protocol independent multicast sparse mode and dense mode.
• C. By default, the RP is needed periodically to maintain sessions with sources and receivers.
• D. By default, the RP is needed only to start new sessions with sources and receivers.

Correct answer: D

Explanation

The correct answer is D because the RP is primarily used to establish new multicast sessions, while existing sessions do not require continuous RP involvement. Options A and B are incorrect as they misrepresent the role of RPs in different multicast modes, and option C incorrectly states that RPs are needed to maintain sessions regularly.
