Which three statements are true about the Internet Group Management Protocol (IGMP)? () A. There are three IGMP modes: dense mode, sparse mode, and sparse - dense modeB. IGMP is used to register individual hosts with a multicast groupC. IGMP version 3 enables a multicast receiving host to specify to the router which sources it should forward traffic fromD. IGMP messages a re IP datagrams with a protocol value of 2, destination address of 224.0.0.2, and a TTL value of 1E. IGMP is a multicast routing protocol that makes packet - forwarding decisions independent of other routing protocols such as EIGRPF. IGMP snooping ru ns on Layer 3 routers

Typically，an IP address refers to an individual host on a particular network. IP also accommodates addresses that refer to a group of hosts on one or more networks.Such addresses are referred to as multicast addresses，and the act of sending a packet from a source to the members of a （71）group is referred to as multicasting. Multicasting done （72） the scope of a single LAN segment is straight forward. IEEE 802 and other LAN protocols include provision for MAC-level multicast addresses. A packet with a multicast address is transmitted on a LAN segment.Those stations that are members of the （73）multicast group recognize the multicast address and （74）the packet.In this case,only a single copy of the packet is ever transmitted.This technique works because of the （本题）nature of a LAN:A transmission from any one station is received by all other stations on the LAN. A .multicastB. unicastC.broadcastD.multiple unicast
