Refer to the exhibit. Which two conclusions can be drawn from the debug ip igmp output?() A. The router sent an IGMP version 2 query out interface Ethernet1 at multicast address 224.0.0.1.B. Router RTA received an IGMP report version 1 from host 192.168.9.1.C. Reverse Path Forwarding (RPF) is ena bled for 192.168.9.4.D. Reverse Path Forwarding (RPF) is enabled for 224.0.1.40.E. The IP multicast groups are 224.0.0.1, 224.0.1.40, and 239.255.0.1.F. IP PIM RP mapping is static.
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
