A customer has Voice IP (VoIP) phones that support Link Layer Discovery Protocol Media
Endpoint Discovery (LLDP-MED). The phase need to receive their VLAN ID using this protocol.
The network architect is proposing HP 5500-48G-PoE+EI switches. Each user computer connects
to the phone, which then connects to the Ethernet jack. LLDP is enabled on the switch. Each Edge
port is trunk port that permits VLAN 10 (the user VLAN) and VLAN 20 (the voice VLAN).
Which other setting recommended on the edge port?
A.
The voice VLAN is enabled
B.
The PVID is set to VLAN 20
C.
LLDP Cisco Discovery Protocol (CDP) compliance enabled
D.
The LLDP voice VLAN ID is set to 20

HP 5500 Series are Comware switches. The phones are LLDP-MED capable, according to the question, so therefore: CDP is not needed, and voice VLAN should NOT be enabled.
According to the study guide:
Port Type: Trunk or Hybrid
PVID (untagged VLAN) = Data VLAN ID
Permitted VLANs = Data VLAN ID, voice VLAN ID
LLDP Voice VLAN = Voice VLAN ID
So, B is NOT correct, as VLAN 20 is the voice VLAN.
Answer is D.
