Selected Answer: C

C. You must enable LLDP-MED on the incoming interfaces and assign the v20 VLAN. Explanation: LLDP-MED (Link Layer Discovery Protocol - Media Endpoint Discovery) is used to automatically discover and configure network devices, especially in the context of IP phones. In this scenario, enabling LLDP-MED on the incoming interfaces and assigning the v20 VLAN will help the switch identify and separate the tagged voice traffic (from the IP phones) and untagged data traffic (from the PCs).
