Refer to the exhibit. What statement is true base d upon the configuration in the exhibit? ()
A. CGMP version 2 is being used.B. The switch will use sparse mode first, dense mode second.C. A rendezvous point must be configured in order for the interface to operate in sparse mode.D. IGMP version 2 is being used.E. The rendezvous point is IP address 172.16.4.16.F. If a rendezvous point is configured, the interface cannot operate in dense mode.

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

Refer to the network of Layer 3 switches in the exhibit. The RPI Multi cast Server only multicasts to hosts connected to multilayer switches 5 and 6. The CMU Multicast Server multicasts to hosts on multilayer switches 1 - 6. Given the number of configuration steps involved, what is the most efficient way to configure the net work while meeting the requirements for multicast data flow? （）A. Configure each switch with PIM sparse mode and a separate instance of PIM dense mode.Specify switch 1 as the root for the RPI Multicast Server. Specify switch 2 as the root for the CMU Multicast Server.B. Configure each switch with PIM sparse mode and a separate instance of PIM dense mode. Leave each multicast server as the root of its own multicast tree.C. Configure each switch with PIM sparse - dense mode. Configure switch 3 as a ren dezvous point for the RPI multicast stream.D. Configure each switch with PIM sparse mode and a separate instance of PIM dense mode.Allow the switches to elect their own root for each multicast tree.E. Configure each switch with PIM sparse mode.F. Configure each switch with PIM dense mode.

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
