Which LLDP-MED feature allows APs to request power as needed from PoE-enabled switch ports?

• A. Voice VLANs can be automatically configured for VoIP phones
• B. APs can request power as needed from PoE-enabled switch ports
• C. iSCSI client devices can request to have flow control enabled
• D. GVRP VLAN information can be used to dynamically add VLANs to a trunk

Answer: (B)

APs can request power as needed from PoE-enabled switch ports is provided by LLDP-MED’s Power via MDI capability. This feature lets devices advertise their power requirements to the switch over LLDP-MED, so the switch can allocate PoE power from its budget accordingly. It enables dynamic PoE negotiation, ensuring the AP gets enough power when it’s needed while avoiding overloading the switch’s power budget. Other LLDP-MED features are about things like assigning VoIP VLANs or discovering VLAN information, but they don’t handle power requests.
