Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 73

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?

Answer options

• A. Voice VLAN
• B. QBSS
• C. WME
• D. QoS routing

Correct answer: A

Explanation

Enabling the Voice VLAN allows the switch to segregate IP voice traffic from client data traffic, ensuring that voice communications receive higher priority and appropriate QoS treatment. The other options, while related to quality of service, do not specifically address the need to separate voice traffic from data traffic in this context.
