Final answer:
In a split-MAC deployment, a WLC manages packet prioritization, resource reservation, and authentication, but not the encryption or handling of beacons and probe responses.
Step-by-step explanation:
Functions performed by a Wireless LAN Controller (WLC) in a split-MAC deployment include packet prioritization, resource reservation, and authentication. While WLCs are responsible for higher-level management operations in a wireless network, encryption is typically performed by the access points alongside other MAC layer operations. Similarly, tasks such as transmitting beacons and handling probe responses are commonly carried out by the access points rather than the WLC to ensure quicker response times and reduced latency.
