Which three statements about the Cisco WCS auto-provisioning feature are true? (Choose three.)
The Cisco WCS (Wireless Control System) auto-provisioning feature allows for the automatic configuration of a new or replacement WLAN (Wireless LAN) controller in the network. Below are the three statements that are true about this feature:
A. Auto-provisioning allows WCS to automatically configure a new or replace a current wireless LAN controller. The auto-provisioning feature of WCS automates the process of configuring a new or replacement WLAN controller. The feature simplifies the process of adding new controllers to the network and reduces the risk of errors that may occur during manual configuration.
B. The service port of the WLAN controller is required to have network connectivity for the auto-provisioning process to begin. The service port of the WLAN controller is a special port used for out-of-band management, and it is used by the auto-provisioning process to access the controller. Network connectivity to this port is required for the auto-provisioning process to begin.
D. DHCP Option 150 (TFTP server address) has to be configured in the DHCP scope options for the auto-provisioning process to begin. The auto-provisioning feature of WCS uses DHCP (Dynamic Host Configuration Protocol) to obtain the IP address of the WLAN controller. DHCP Option 150, which specifies the IP address of the TFTP (Trivial File Transfer Protocol) server, is required to be configured in the DHCP scope options for the auto-provisioning process to begin.
Therefore, options A, B, and D are true statements about the Cisco WCS auto-provisioning feature.
C. DHCP Option 43 (vendor-specific information) has to be configured in the DHCP scope options for the auto-provisioning process to begin. DHCP Option 43 is used to specify vendor-specific information, such as the IP address of the WCS server, to the DHCP client. While it can be used for the auto-provisioning process, it is not a requirement for it to begin.
E. Using the add filter command in WCS will create a controller configuration file. The add filter command in WCS is used to create a filter for specific controller types, and it is not related to the auto-provisioning process.
F. WCS auto-provisions the management interface of the WLAN controller by pushing a predefined template. While WCS can push a predefined template to the WLAN controller during the auto-provisioning process, it is not limited to the management interface only. The auto-provisioning process can configure other interfaces as well.
In conclusion, the correct answers are A, B, and D.
