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.
