A multicast router may receive thousands of multicast(71)every day for different groups. If a router has no knowledge about the membership status of the(72), it must broadcast all of these packets. This creates a lot of traffic and consumes(73). A better solution is to keep a list of groups in the network for which there is at least one loyal member.(74)helps the multicast router create and update this list. For each group, there is one router that has the duty of distributing the(75)packets destined for that group. This means that if there are three multicast routers connected to a network, their lists of groupids are mutually exclusive. A host or multicast router can have membership in a group.A．packetsB．errorsC．reportsD．alarms

Which two statements are true about Internet Group Management Protocol (IGMP) snooping?()
A. IGMP snooping and Cisco Group Membership Protocol (CGMP) can be used simultaneously on a switch.B. IGMP snooping a nd Cisco Group Membership Protocol (CGMP) were developed to help Layer 3 switches make intelligent forwarding decisions on their own.C. IGMP snooping examines IGMP join/leave messages so that multicast traffic is forwarded only to hosts that sent an IG MP message toward the router.D. IGMP snooping is an IP multicast constraining mechanism for Layer 2 switches.E. IGMP snooping is enabled with the ip multicast - routing global configuration command.

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
