A network technician needs to configure a switch port to support both voice and data traffic for an IP phone that has a PC connected through it. The requirement is to separate the traffic into different VLANs for voice and data, while keeping the port in access mode. Which port configuration will meet these requirements?
Configure the port to dynamic desirable mode
Configure the port as a trunk, allowing both voice and data VLANs
Set the port to access mode and assign the data VLAN; use the command to specify the voice VLAN
Set the port to access mode and assign the voice VLAN
To support both voice and data traffic on a single switch port connected to an IP phone and a PC, the port should be configured as an access port assigned to the data VLAN. The switchport voice vlan command is then used to specify the voice VLAN. This configuration allows the IP phone to tag voice traffic with the voice VLAN, while data traffic from the PC remains untagged on the data VLAN. Configuring the port as a trunk is unnecessary and can introduce security risks. Assigning the port only to the voice VLAN would isolate data traffic from the PC. Dynamic desirable mode is used for trunk negotiation and is not suitable in this scenario.
