NEW QUESTION # 80
IGMPv2 uses the timeout mechanism for group members leaving a group. Group members can only leave a group silently. Before the timeout period expires, multicast traffic is still forwarded by the multicast router, and this is a defect.

Answer: A

Explanation:
This statement isfalsebecauseIGMPv2 improves upon IGMPv1 by introducing the Leave Group message.
InIGMPv1, members leave silently, and the router waits for the timeout.
InIGMPv2, a host sends aLeave Groupmessage, prompting the router to send aGroup-Specific Queryto determine if other members are still present. If no responses are received, the group is pruned before timeout.
Reference from Huawei HCIP-Datacom-Core Technology Study Guide:
"IGMPv2 allows group members to actively send Leave messages, reducing unnecessary forwarding delays.
This improves efficiency over IGMPv1."
(Chapter: Multicast Protocols - Section: IGMP Versions)
