D.  

All the network ingress ports on the same MDA share a buffer pool.

A.  

Limiting the maximum forwarding rate of each individual policer and, at the same time, marking, packets as in-profile or out-of-profile.

B.  

Putting packets in a buffer as they are received, and marking packets as in-profile or out-of-profile as they are removed from the buffer.

C.  

Rate-limiting the collective output of several policers, and to reallocate bandwidth that is not utilized by some policers to other policers that need to use it.

D.  

Rate-limiting the collective output of several policers towards each egress FFPC, while maintaining control of the maximum overall forwarding rate.

A.  

WRED monitors the shared buffer space utilization over a period of time.

B.  

WRED disables the TCP slow-start congestion control mechanism.

C.  

WRED uses two configurable slopes for each buffer pool: a high slope and a low slope.

D.  

WRED uses the shared buffer utilization, instead of the individual queue depth, to get a better picture of the average resource utilization of the shared buffer space.
