is a protocol that a host uses to inform. a router when it joins or leaves an Internet multicast group。A．SMTPB．ICMPC．MIMED．IGMP
Which two multicast protocol statements are true?() A. Sparse mode multicast uses a pull model to send multicast traffic to where it is requestedB. Dense mode multicast uses a push model to flood traffic throughout the network and then prunes the unwanted trafficC. Dense mode multicast requires explicit join messa ges from their membersD. Sparse mode uses reverse path forwarding (RPF) to prune off redundant flowsE. The primary use of sparse mode multicast is for test labs and router performance testing
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
