A profile-mode queue is configured with MBS = 100 KB, CBS = 50 KB and High-Priority-Only = 40%. Assume there is no CBS overbooking, and the slope-policy is disabled. If the current queue depth is 70 KB, what will happen to an out-of-profile packet when it is transmitted to the queue?
Given the configuration of MBS = 100 KB, CBS = 50 KB, and High-Priority-Only = 40%, this means that once the queue depth exceeds 60% of 100 KB (i.e., 60 KB), only high-priority packets are allowed. Since the current queue depth is 70 KB, which is above the high-priority-only threshold, any out-of-profile packet transmitted to the queue would be discarded.
The correct option is D, the HPO is above (100K- 60K) of the queue debt, at 70K only high priority are allowed to go into the queue, low priority are discarded
