D. acts as the designated router for a broadcast segment when multicast routing is enabled
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 0
B. The reverse path forwarding (RPF) for the route 224.2.0.1 failed to find the interface on which the multicast packet was rece ived
C. Multicast route to 224.69.15.0/24 was added to the mroute table and created by a source directly connected to the router
D. Multicast route to 10.16.0.0/16 was added to the mroute table and created by a source directly connected to the router
E. This router received an IGMP host report from a group member or a PIM join message
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.
