Hello,
IGMP is a communications protocol. It is not a routing protocol. You are also missing one correct answer which is IGMP snooping runs on Layer 3 routers. This is indeed correct. See link
http://en.wikipedia.org/wiki/Internet_Gr...t_Protocol
25. (QID:NG16) Which three statements are true about the Internet Group Management Protocol (IGMP)? (Choose three)
IGMP is used to register individual hosts with a multicast group.
IGMP is a multicast routing protocol that makes packet-forwarding decisions independent of other routing protocols such as EIGRP.
IGMP version 3 enables a multicast receiving host to specify to the router which sources it should forward traffic from.
IGMP messages are IP datagrams with a protocol value of 2, destination address of 224.0.0.2, and a TTL value of 1.
There are three IGMP modes: dense mode, sparse mode, and sparse-dense mode.
IGMP snooping runs on Layer 3 routers.
Correct Answer:
