CCIE Wireless (legacy) — Question 3

You are the wireless administrator for ACME corporation. You must configure a Cisco Catalyst 3850 Series Switch to work as mobility agent to allow access point association to this switch.

Answer options

• A. Access point must be connected to an access port that has the access VLAN configured to be the same as the service port VLAN on the Catalyst 3850 switch.
• B. Access point must be connected to an access port with the access VLAN configured to be any VLAN that has a Layer 3 interface (SVI) on the Catalyst 3850 switch.
• C. Access point must be connected to an access port with the access VLAN configured to be the same as the wireless management VLAN on the Catalyst 3850 switch.
• D. Access point must be connected to an access port that has the access VLAN configured to be the same as the management VLAN for the switch stack.
• E. Access point must be connected to a trunk port with the native VLAN set to 1 in order to join the WLC on the Catalyst 3850 switch.

Correct answer: E

Explanation

The correct answer is E because access points must connect to a trunk port with the native VLAN set to 1 to communicate properly with the Wireless LAN Controller (WLC). Options A, B, C, and D are incorrect as they suggest configurations that would not facilitate proper access point association to the WLC on the Catalyst 3850 switch.
