Ruckus Certified Network Integrator (RCNI) — Question 7

For multicast clients to stop receiving traffic using a leave request, which protocol must run on the local subnet?

Answer options

• A. IGMPv2
• B. IGMPv1
• C. PIM Dense
• D. IGMP Snooping

Correct answer: A

Explanation

IGMPv2 is the protocol that allows multicast clients to communicate their desire to leave a multicast group, effectively stopping the traffic. IGMPv1 does not support leave requests, PIM Dense is a routing protocol for multicast but does not handle client requests, and IGMP Snooping is a network switch feature for managing multicast traffic but does not directly process leave requests.
