You have a strict-high queue configured. You notice that under bursty traffic conditions, there are tail drops on
the strict-high queue.Which action would solve this problem?

A.
Assign a policer on ingress to assign a low packet loss priority to the strict-high queue.

B.
Decrease the buffer size of the strict-high queue.

C.
Assign a policer on egress to assign a low packet loss priority to the strict-high queue.

D.
Increase the buffer size of the strict-high queue.

Explanation:
A queue with strict-high priority is assured unlimited transmission bandwidth but is not actually assigned a large
delay buffer. Not configuring a transmit-rate or an explicit buffer-size on a strict-high priority queue only ensures
that the queue gets assigned a default minimum delay buffer, making it possible, under bursty conditions, to
see tail-drops on strict-high priority queues. Assigning a small transmit-rate or an explicit temporal or
percentage buffer-size to the queue ensures that the queue has a large enough buffer to hold bursts and
protect against tail-drops.
