QUESTION: 71

A queue is configured with the following attributes:

MBS = 10KB
CBS = 5KB
High-Priority-Only = 30%

Assume that there is no CBS overbooking and that the slope-policy is disabled. If the current queue depth is 8KB, what will happen to an in-profile packet arriving in the queue?

It will be discarded because the high-priority-only threshold is exceeded.
It will be queued but re-marked as "out-of-profile."
It will be queued in the reserved portion of the buffer pool and remain "in-profile."
It will be queued in the shared portion of the buffer pool but contend for shared buffer space with packets from other queues.
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.

When the shared buffer utilization reaches 51%, in-profile packets might be dropped.
