What characteristic describes how data or voice VLANs are configured on a network?

Voice VLANs are configured on a trunk link between the IP phone and the switch.
A switch port that has been configured in access mode can only belong to one data VLAN at a time.
The switchport access vlan command must specify a VLAN currently configured in the vlan.dat file
Data and voice VLANs have a different value range for VLAN IDs.

Explanation: A switch access port can belong to only one data VLAN at a time, but a port can also be associated to a voice VLAN. A switch access port connecting to an IP phone must support VLAN traffic for voice and data. The switchport access vlan command forces the creation of a VLAN if it does not already exist on the switch.
