An engineer is tasked with placing a guest access anchor controller in the DMZ. Which two ports or port sets must be opened up on the firewall to accomplish this task? (Choose two.)

UDP port 1812 is used for RADIUS authentication, which, while relevant for guest authentication, is not solely focused on the management and logging of the anchor controller itself as the question implies.

TCP port 161 is the standard port for SNMP (Simple Network Management Protocol) agents, used for network management and monitoring of devices like Wireless LAN Controllers. Opening this port allows the anchor controller to be managed and monitored from external management stations in the DMZ.

TCP port 514 is commonly used for Syslog, which is essential for sending logging and event messages from the WLC (anchor controller) to a syslog server for monitoring, auditing, and troubleshooting purposes.

UDP port 79 is for the Finger protocol, which is not typically used for guest access anchor controller operations or management.

UDP port 16666 is not a standard port for core guest access anchor controller operations or management.
