Answer: A B

Explanation:

These are two benefits enabled by LLDP-MED (Link Layer Discovery Protocol – Media Endpoint Discovery).

LLDP-MED is an extension of LLDP that provides additional capabilities for network devices such as VoIP phones and APs. One of the capabilities is to automatically configure voice VLANs for VoIP

phones, which allows them to be placed in a separate VLAN from data devices and receive QoS and security policies.

Another capability is to request power as needed from PoE-enabled switch ports, which allows APs to

adjust their power consumption and performance based on the available power budget. The other

options are incorrect because they are either not enabled by LLDP-MED or not related to LLDP-MED.
