A network engineer is deploying 8865 IP phones with wireless clients connected to them.
In order to apply the appropriate QoS, the IP voice traffic needs to be distinguished from client data traffic.
Which switch configuration feature must be enabled?

A. B. C. D.A.
The correct answer is A. Voice VLAN.
Explanation:
To apply QoS to IP voice traffic and distinguish it from client data traffic, the network engineer needs to use a feature called Voice VLAN.
Voice VLAN is a switch configuration feature that enables the separation of voice traffic from data traffic by assigning voice traffic to a separate VLAN. By doing so, the switch can prioritize voice traffic over data traffic, ensuring that voice traffic receives the necessary bandwidth and low latency it requires for high-quality voice communication.
The other answer choices, QBSS, WME, and QoS routing, are not directly related to the separation of voice and data traffic for QoS purposes.
QBSS (Quality of Service Basic Service Set) is a Wi-Fi standard that allows wireless clients to request bandwidth from an access point to improve their QoS. However, it does not provide a mechanism to separate voice and data traffic.
WME (Wi-Fi Multimedia Extensions) is another Wi-Fi standard that provides QoS enhancements, such as prioritization of different types of traffic. However, it also does not provide a mechanism to separate voice and data traffic.
QoS routing is a routing technique that enables the network to provide different levels of service to different types of traffic. While it can help prioritize voice traffic, it does not provide a way to separate voice and data traffic for QoS purposes.
Therefore, the correct answer is A. Voice VLAN.
