（A）When PIM is used, the unicast routing topology has no impact on the multicast topology.

（B）Multicast traffic may follow a different path than unicast traffic between the same two points.

（C）A distinct multicast topology can be created instead of using the unicast topology.

（D）Multicast relies on an existing IP routing infrastructure.

（A）It is the path to the RP

（B）It is how receivers signal the source

（C）It is the multicast data forwarding path

（D）It is how PIM neighbors become aware of each other

（E）It is the path to the DR

（A）It issues an IGMP Group Specific Query,

（B）It sends a PIM (S, G) prune to the source.

（C）It issues an IGMP General Query.

（D）It sends a PIM (* G) prune to the RP, and a PIM (S, G) prune to the source,

（E）It sends a PIM (*, G) prune to the RP.

（A）The router will send a PIM (192.168.1.1,232.1.1.1) Join

（B）The router will propagate a (*, 239.1.1.1) join towards RP if it exists

（C）The router will randomly pick a source from 192.168.1.1 and 192.168.1.2 and send an (S, G)join towards the source

（D）The IGMPv3 report will be dropped and a log about misconfiguration will be generated

（A）Layer 7

（B）Layer 4

（C）Layer 2

（D）Layer 1

（E）Layer 3

（A）2 static RP's both with override cannot be configured on the same device

（B）10.10.10.24 will be RP for 230.1.1.1 and 10.10.10.66 will be RP for 234.1.1.1

（C）2 static RP's cannot be configured on the same device

（D）10.10.10.24 will be RP for 234.1.1.1 and 10.10.10.66 will be RP for 230.1.1.1

（A）MPLS encapsulation for multicast data traffic.

（B）GRE encapsulation for multicast data traffic.

（C）PIM in the service provider's core network.

（D）PIM in the VRF.

（A）Multicast traffic does not need a reliable transport.

（B）Reliability may be added with a higher layer protocol such as RTP (Real Time Protocol).

（C）UDP provides reliable transport for multicast traffic.

（D）TCP provides reliable transport for multicast traffic.

（A）Shared Path Tree

（B）Source Path Tree

（C）Switchover Path Tree

（D）Special Path Tree

（E）Spanning Tree

（A）1

（B）7

（C）2

（D）6

（A）Layer 7

（B）Layer 4

（C）Layer 2

（D）Layer 1

（E）Layer 3

（A）No. As the embedded-rp group-range is wrong

（B）No. As the "rpf6-table" command is missing

（C）No. The configuration of PIM is no problem, but the scope of the group address used to send traffic is wrong

（D）Yes. The configuration of PIM is correct and the receiver should get traffic from the source

（A）33:33:12:34:56:78

（B）33:33:FF:34:56:78

（C）33:33:FF:FE:56:78

（D）33:33:FE:34:56:78
