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.

- C . Packet enters a node will be treated as per the local hop’s configured policy.
- D . Native IP packets entering a network port will be marked at the first network egress by default
- E . Native IP packets entering a network port will not be marked at the first network egress by default.
- F . Native IP packets entering a network port will be marked at the first network egress, regardless of the re-marking configuration.
