Question 33

Click the exhibit button below. Given the slope-policy (below), which of the following statements are TRUE? (Choose two)

All out-of-profile traffic will be dropped before that of any in-profile traffic.

The discard probability slope of an in-profile traffic is steeper than that of an out-of-profile traffic.

When the shared buffer utilization reaches 55%, both in-profile and out-of-profile packets may be dropped.

The maximum probability with which an out-of-profile packet can be dropped is higher than that of an in-profile packet.

When the shared buffer utilization is at 61%, only in-profile packets are currently in the shared buffer pool.
