A. B. C. D.AC.
The Cisco Wireless Services Module (WiSM) is a component of the Cisco Wireless LAN Controller (WLC) system, which provides centralized management and control of wireless access points (APs) in a wireless network. The WiSM module provides high availability and scalability features for enterprise wireless networks.
The WiSM controller has multiple interface types that can be configured based on the requirements of the wireless network. These interface types include:
Virtual Interface: A virtual interface is a logical interface that can be used to provide network connectivity to multiple wireless networks (SSID). The virtual interface is associated with a specific WLAN (Wireless Local Area Network) and can be used to configure wireless security, QoS, and other wireless network settings.
Virtual Gateway Interface: The virtual gateway interface is used to provide Layer 3 routing between wireless clients and the wired network infrastructure. The virtual gateway interface can be used to route traffic between different VLANs and subnets.
Service Port Interface: The service port interface is used to connect the WiSM controller to an external management network or a network for out-of-band management. This interface is typically used for initial configuration and troubleshooting of the WiSM controller.
Operator Defined Interface: This is a user-defined interface that can be used to provide additional connectivity options to the WiSM controller.
When setting up a Cisco WiSM controller, two interface types that must be present and configured are the virtual interface and the service port interface.
The virtual interface is required because it is used to provide network connectivity to wireless clients, and it is associated with a specific WLAN that provides wireless access.
The service port interface is required because it is used to connect the WiSM controller to an external management network or a network for out-of-band management. This interface is typically used for initial configuration and troubleshooting of the WiSM controller.
Therefore, options A and C (virtual and service port interfaces) are the correct answers to this question.
