Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 219

A company has an existing Cisco wireless solution deployed to a remote branch location with centrally switched control and data traffic. A new solution is needed to locally switch client traffic when Wi-Fi is used. A new SSID that is used only for voice devices must be mapped to an onsite voice VLAN named VLAN 25. Which configuration on the switch interface that connects to the APs meets the requirement?

Answer options

• A. switchport mode trunk switchport trunk allowed vlan add vlan 25
• B. switchport mode access switchport access vlan 25
• C. switchport mode trunk switch trunk native vlan 25
• D. switchport mode access switchport access vlan 25 switchport access voice vlan 25

Correct answer: A

Explanation

The correct answer is A because configuring the switch port as a trunk allows multiple VLANs, including VLAN 25 for the voice SSID, to be carried over the link. Option B does not allow for trunking and would not accommodate the requirements for multiple VLANs, while options C and D do not provide the necessary trunk configuration to support the voice VLAN effectively.
