D. The two anycast RPs must be IBGP peers.
Which two of these statements correctly describe classic PIM-SM? (Choose two.)
A. The IOS 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 IOS 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 pim spt-threshold command to “infinity.”
D. 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 pim spt-threshold command to “zero.”
In Layer 2 topologies, spanning-tree failures can cause loops in the network. These unblocked loops can cause network failures because of excessive traffic. Which two Catalyst 6500 features can be used to limit excessive traffic during spanning-tree loop conditions? (Choose two.)

B. storm control
C. storm suppression
D. broadcast suppression
E. BPDU guard

D. it is not timer-based
Under which two circumstances would an RSTP bridge flush its CAM table? (Choose two.)

B. upon receiving a topology change notification
C. when transitioning from discarding to forwarding
D. when transitioning from forwarding to discarding
E. only when changing from listening to discarding
F. when CAM resources have been completely used up
Which of these correctly identifies a difference between the way BPDUs are handled by 802.1w and 802.1D?

A. Be = 46320000 , Bc = 96000
B. Be = ,768000 Bc = 32000
C. Be = ,128000 Bc = 7680
D. Be = ,0 Bc = 96000
