Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Low Latency Queuing (LLQ)
Low Latency Queuing (LLQ) combines priority queuing with Class-Based Weighted Fair Queuing (CBWFQ) to provide strict priority for latency-sensitive traffic like video.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Weighted Fair Queuing (WFQ)
Why it's wrong here
WFQ does not provide the strict priority required for video traffic.
- ✗
Priority Queuing (PQ) only
Why it's wrong here
PQ can lead to starvation of other traffic; LLQ is preferred for better control.
- ✗
Random Early Detection (RED)
Why it's wrong here
RED is a congestion avoidance mechanism, not a queueing strategy.
- ✓
Low Latency Queuing (LLQ)
Why this is correct
LLQ is the industry standard for handling real-time video/voice traffic.
