How does LLQ ensure that voice traffic is always expedited?

A.
LLQ adds a strict priority class to CBWQF. The class allows delay-sensitive data such as voice
to be dequeued and sent first.

B.
LLQ uses CBWFQ to prioritize voice traffic and dequeue the voice packets so that they can be
handled first.

C.
The strict priority queue has a higher weight than the queues in CBWFQ. This weight allows the
delay sensitive data such as voice to be dequeued and sent first.

D.
The LLQ strict priority queue allows delay-sensitive data such as voice to be dequeued and
sent first (before packets in order queue are dequeued), giving delay sensitive data preferential
treatment over other traffic.
