The ASBRs use MP-iBGP to peer with PE routers in their autonomous system and exchange VPN-IPv4 routes.

C.

The ASBRs maintain a mapping of labels for IPv4 routes exchanged between autonomous systems.

D.

Allows a PE router to load share traffic across routes learned from both direct CE-PE peerings and MP-BGP peerings.

Which of the following statements is considered best practice when changing a network policy that has been associated with an interface?

A.

The policy should be placed in a "shutdown" state before changes are made.

B.

A new network policy should be created and applied to the interface, overwriting the previous policy.

C.

The policy must first be removed from the interface, then modified and re-applied to the interface.

D.

Before the policy can be changed, it must be deleted with the no network qos command.

E.

Before any changes are made to the policy, all network interfaces where the policy is applied have to be shut down.

A queue is configured with the following attributes:

MBS = 10KB

CBS = 5KB

High-Priority-Only = 20%

Assume that there is no CBS overbooking and that the slope-policy is disabled. If the current queue depth is 3KB, what will happen to an out-of-profile packet arriving at an egress queue?

A.

It will be queued in the reserved portion of the buffer pool and remain out-of-profile.

B.

It will be queued in the reserved portion of the buffer pool if there are no in-profile packets already in the queue.

C.

It will be queued in the reserved portion of the buffer pool and be in-profile.

D.

It will be queued in the shared portion of the buffer pool but contend for shared buffer space with packets from other queues.

E.

It will be queued in the shared portion of the buffer pool but may be dropped if the buffer utilization exceeds the start-average value of the low slope.
