Implementing Cisco SD-WAN Solutions (ENSDWI) — Question 217

An engineer must configure egress QoS for voice traffic. Which queue must the engineer configure on the WAN Edge router to accomplish the task?

Answer options

• A. queue 0
• B. queue 1
• C. queue 3
• D. queues 7

Correct answer: A

Explanation

Queue 0 is typically reserved for high-priority traffic such as voice, making it the correct choice for egress QoS configuration for voice traffic. The other options, queues 1, 3, and 7, may not provide the same level of priority necessary for voice communication, which can lead to delays and poor call quality.
