By default, how does a hybrid port on a Nokia 7750 SR share its allocated buffer space between access and network pools?

A.

A.

The primary contributors to latency are distance, scheduling, and congestion.

B.

The weighted round robin scheduling algorithm will result in more delay for high priority traffic than the regular round robin algorithm.
