Designing Cisco Enterprise Networks (ENSLD) — Question 302

Which queuing structure is used on SD-WAN Edge routers?

Answer options

• A. FIFO
• B. LLQ+WFQ
• C. 1P-4Q-2T
• D. Priority

Correct answer: B

Explanation

The correct answer is B, LLQ+WFQ, as it combines Low Latency Queuing and Weighted Fair Queuing to optimize traffic management on SD-WAN Edge routers. Options A, C, and D do not provide the same level of traffic prioritization and handling as LLQ+WFQ does, making them less suitable for this specific context.
