Question 1

Which description describes the low latency queuing algorithm?

A. Empty queue 1. If queue 1 is empty, empty queue 2, then empty queue 3, unless a packet for a higher queue arrives.
B. An administrator defines the traffic classes based on match criteria, including protocols, access control lists, and input interfaces.
C. A flow-based algorithm that simultaneously schedules interactive traffic to the front of a queue to reduce response time and fairly shares the remaining bandwidth among high-bandwidth flows.
D. This feature brings strict priority queuing to CBWFQ.
E. Packets are placed into a single queue and serviced in the order they were received.


Answer: D
