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
考题
What are three methods that may be use d to allow a switch to determine which ports to forward IP multicast messages to?()
A. IGMPB. IGMP snoopingC. PIMD. CGMPE. static assignmentF. CDP
考题

A. acts as a meeting place for sources and receivers of multicast trafficB. used in PIM dense m ode to create a database of all multicast sourcesC. used in PIM dense and sparse mode to create a database of all multicast sourcesD. acts as the designated router for a broadcast segment when multicast routing is enabled
考题
Refer to the exhibit. IP multicast for group address 224.1.1.1 has been enabled on all router s in the network. Hosts on Network A receive the multicast traffic. However, hosts on Network B do not. On the basis of outputs provided, what could be the cause of the problem? （）A. The route to 224.69.15.0/24 will be out Ethernet 0B. The reverse path forwarding (RPF) for the route 224.2.0.1 failed to find the interface on which the multicast packet was rece ivedC. Multicast route to 224.69.15.0/24 was added to the mroute table and created by a source directly connected to the routerD. Multicast route to 10.16.0.0/16 was added to the mroute table and created by a source directly connected to the routerE. This router received an IGMP host report from a group member or a PIM join message
考题
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.
考题
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
