Click the exhibit button below. Given the output of the #show pools 1/2/2 network-egress command on a GigE port, what can the service provider deduce? (Choose two)

  1. QoS is not configured on the router.
  2. Packets in forwarding classes "be" and "12" are being queued.
  3. Traffic belonging to forwarding class "ef" is not experiencing queuing delays.
  4. Traffic belonging to forwarding class "11 "will never make use of the shared buffer pool.
  5. Out-of-profile traffic in the shared buffer pool is being dropped.

Answer(s): B,C



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?

  1. It will be queued in the reserved portion of the buffer pool and remain out-of-profile.
  2. It will be queued in the reserved portion of the buffer pool if there are no in-profile packets already in the queue.
  3. It will be queued in the reserved portion of the buffer pool and be in-profile.
  4. It will be queued in the shared portion of the buffer pool but contend for shared buffer space with packets from other queues.
  5. 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.

Answer(s): A
