QUESTION 251

The ip pim autorp listener command is used to do which of these?

 

A.       enable a Cisco router to “passively” listen to Auto-RP packets without the router actively sending or forwarding any of the packets

B.       allow Auto-RP packets in groups 224.0.1.39 and 224.0.1.40 to be flooded in dense mode out interfaces configured with the ip pim sparse-mode command

C.       enable the use of Auto-RP on a router

D.       configure the router as an Auto-RP mapping agent

 

Correct Answer: B

 

 

QUESTION 252

In order to configure two routers as anycast RPs, which of these requirements, at a minimum, must be satisfied?

 

A.       Multicast Source Discovery Protocol mesh-groups must be configured between the two anycast RPs.

B.       The RPs must be within the same IGP domain.

C.       Multicast Source Discovery Protocol must be configured between the two anycast RPs.

QUESTION 253

Which two of these statements correctly describe classic PIM-SM? (Choose two.)

 

A.       The lOS default is for a last-hop router to trigger a switch to the shortest path tree as soon as a new source is detected on the shared tree.

B.       The lOS default is for every one of the routers on the shared tree to trigger a switch to the shortest path tree as soon as a new source is detected on the shared tree.

C.       The default behavior of switching to the shortest path tree as soon as a new source is detected on the shared tree can be disabled by setting the value in the ip pirn spt-threshold command to “infinity.

D.       The default behavior of switching to the s
hortest path tree as soon as a new source is detected on the shared tree can be disabled by setting the value in the ip pirn spt-threshold command to “zero.”
