A LAN contains three hosts subscribed to 239.10.10.10 and one IGMPv2 querier. Host-A sends a Membership Report first. Host-B and Host-C receive that report before their response timer expires. Assuming default IGMP behavior and no packet loss, what occurs next?
Two multicast routers running IGMPv2 exist on the same subnet: R1 = 10.1.1.10 R2 = 10.1.1.20 Initially both send General Queries. After election stabilizes, which statement is correct?
An IGMPv2 host leaves group 239.1.1.1 and sends Leave to 224.0.0.2. Router immediately starts Last Member Query processing. Why is traffic not instantly removed?
A network engineer reduces Query Response Interval from 10 sec to 1 sec. What is the most likely operational effect?
A host joins 239.20.20.20 on an IGMPv2 LAN and sends Membership Report immediately. The router receives no Join messages from any other host afterward. Why does multicast forwarding continue?
A multicast capture shows General Query packets sent to 224.0.0.1 every 125 seconds. No Leave messages are observed. Which IGMP version most likely exists?
During troubleshooting, one engineer claims IGMPv1 elects a DR. Which statement is correct?
Host-A leaves a group. Router sends Group-Specific Query and Host-B still listens. What packet should Host-B transmit?
If Group-Specific Query receives no Membership Reports before expiration, router should:
A packet capture shows Membership Report destination equals 239.10.10.10 instead of 224.0.0.2. Which statement is correct?
