Which controller interface type maps a WLAN to a VLAN?

(A) Management interface
(B) Redundancy management
(C) Virtual interface
(D) Service port interface
(E) Dynamic interface

Dynamic interface is the correct answer.

Cisco controllers support the following interface types:

1. Dynamic interface: Used to connect a VLAN to a WLAN.
2. Management interface: Used for normal management traffic, such as RADIUS user authentication, WLC-to-WLC communication, web-based, and SSH sessions, SNMP, Network Time Protocol (NTP), syslog, and so on. The management interface is also used to terminate CAPWAP tunnels between the controller and its APs.
3. Redundancy management: The management IP address of a redundant WLC that is part of a high availability pair of controllers. The active WLC uses the management interface address, while the standby WLC uses the redundancy management address.
4. Virtual interface: IP address facing wireless clients when the controller is relaying client DHCP requests, performing client web authentication, and supporting client mobility.
5. Service port interface: Bound to the service port and used for out-of-band management.
