Why each option

This question asks for the correct queue value to prioritize voice traffic when configuring QoS on a Cisco SD-WAN WAN Edge router via vManage GUI.

A0Correct

In many Cisco QoS implementations, the lowest queue number, typically 0, is designated for the highest priority traffic. Voice traffic requires strict low latency and minimal jitter, making it a prime candidate for the highest-priority queue, commonly queue 0 in the vManage QoS configuration.

B1

While 1 is a low queue number, 0 is typically the absolute highest priority queue when available for critical traffic like voice.
