Before connecting your Access Points to the network, ensure licenses and the correct time is set on the controller.

B. Activate the appropriate Right-to-Use AP license on the wireless LAN controller:
The Right-to-Use AP license is a feature that enables the WLC to support APs without requiring a permanent AP license. The WLC requires an AP license to support APs, and this license can be a Right-to-Use license or a Permanent license. The Right-to-Use license is temporary, whereas the Permanent license is perpetual. The Right-to-Use license allows the AP to join the WLC for a limited time, usually 90 days, after which the license must be renewed. Therefore, before any APs can join the WLC, the appropriate Right-to-Use AP license must be activated on the WLC.
D. Ensure accurate configuration of the correct time and the date on the wireless LAN controller:
The WLC uses the date and time information to enforce security policies, generate log messages, and perform other system functions. Accurate time synchronization between the APs and the WLC is also important for proper operation of the network. Therefore, it is essential to configure the correct date and time on the WLC. The WLC can synchronize its time with a Network Time Protocol (NTP) server, which can be an external server or another device on the network that is configured as an NTP server.
A. Enable ip dhcp snooping trust on the wireless controller port-channel interface:
Enabling DHCP snooping trust on the wireless controller port-channel interface is not necessary to ensure that APs will successfully join the Cisco WLC. DHCP snooping trust is a feature that is used to mitigate DHCP attacks by allowing only trusted DHCP servers to provide IP addresses to clients. This feature is typically used in wired networks and is not relevant to the wireless network.
C. Ensure that Port-Fast is enabled on each access point switch port:
Enabling Port-Fast on each access point switch port is not necessary to ensure that APs will successfully join the Cisco WLC. Port-Fast is a Cisco Catalyst switch feature that is used to minimize the time that a port remains in the blocking state when it is first activated. This feature is typically used to speed up the process of connecting end devices to the network and is not relevant to the wireless network.
