Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 496

A network engineer is designing a QoS policy for voice and video applications. Which software queuing feature provides strict-priority servicing?

Answer options

• A. Class-Based Weighted Fair Queuing
• B. Low Latency Queuing
• C. Link Fragmentation
• D. Automatic QoS

Correct answer: B

Explanation

Low Latency Queuing (LLQ) is specifically designed to provide strict-priority servicing, ensuring that voice and video traffic is prioritized over other types of traffic. The other options, such as Class-Based Weighted Fair Queuing and Automatic QoS, do not provide the same level of strict priority needed for real-time applications, and Link Fragmentation is unrelated to queuing mechanisms.
