QUESTION 384

Which two statements about a backup tunnel to avoid the SRLGs of its protected interface are true? (Choose two.)

 

A.

Tunnel is not created unless it avoids SRLGs on the protected interface.

B.

If it is not possible to avoid SRLG of the protected interface, backup tunnel will be created anyways.

QUESTION 386

Which two characteristics must be considered when implementing IP dampening on Cisco IOS? (Choose two.)

 

A.

C.

The reuse threshold defaults to 1000 penalties if it is not configured.

D.

IP dampening can track the individual subinterfaces on an interface.
