A. Either PIM or IGMP

B. IGMP

C. Both PIM and IGMP

D. PIM

A. Customer group membership must be signaled by BGP A-D.

B. Customer group membership must be signaled by BGP A-D or PIM.

C. If the I-PMSI is signaled by BGP A-D, then the S-PMSI must be signaled by BGP A-D.

D. If the I-PMSI is signaled by PIM, then the S-PMSI must be signaled by BGP A-D.

A. The aim of multicast CAC is to maintain the quality of existing IPTV channels by rejecting new channel joins when required

B. Multicast CAC policy can be applied to VPLS SAP and SDP with IGMP-snooping

C. Multicast CAC allows a service provider to guarantee the availability of mandatory IPTV channels

D. Multicast CAC measures the current bandwidth utilization on the physical links and then decides whether to accept a new channel or not

A. Avoid the issue of shared-tree traffic concentration on a single RP in the network

B. Provide more optimal routing of the Shared Path Tree by allowing redundant RPs to be located closer to receivers

C. Used to support incongruent topologies

D. Provide RP redundancy in a PIM SM network

E. Provide more optimal routing of the Source Path Tree by allowing the receiver to connect to the closest multicast source

A. The customer is sending multicast traffic to group 239.1.1.1.

B. The I-PMSI group address is 232.10.10.0.

C. 192.168.1.2 is the IP address of the multicast source.

D. The S-PMSI is instantiated by GRE tunnels.

A. The PE sends an (S, G) PIM Join with no encapsulation.

B. The PE sends an (S, G) PIM Join with GRE encapsulation.

C. The PE sends a (*, G) PIM Join with no encapsulation.

D. The PE sends a (*, G) PIM Join with GRE encapsulation.

A. The router tears down either channel 239.1.1.1 or 239.1.1.2 first, and then establishes a new channel for 239.1.1.6.

B. No existing channel is torn down, and the new channel for 239.1.1.6 is established as there are enough resources.

C. The new channel 239.1.1.6 cannot be established, and a log is generated.

D. The router tears down channel 239.1.1.3 first, and then establishes a new channel for
239.1.1.6.

A. The customer is sending multicast traffic to group 239.1.1.1.

B. The S-PMSI group address range is 232.10.10.0/24.

C. The S-PMSI is instantiated by MPLS tunnels.

D. 192.168.1.2 is the system IP address of the source PE.

A. From the default gateway address of unicast frames

B. From the IGMP Queries received

C. From the IGMP Host Membership Reports received

D. The switch issues a message on all ports to which only routers respond

E. The same way as it identifies receivers

A. Only one, and S is PE1.

B. None, as RPonly maintains (*,G) state.

C. Only one, and S is the MC source server's IP address.

D. Three, and S is PE1, PE2 and PE3 respectively.
