One solved question, so you can see how these are marked
On a switch access port connecting both a PC and an IP phone (with the PC plugged into the phone's built-in switch port), which command tells the switch which VLAN the phone's voice traffic belongs to?
switchport voice vlan <vlan-id>
switchport voice vlan assigns a separate voice VLAN to an access port, allowing an attached IP phone's traffic to be tagged and separated from the PC's untagged data traffic on the same physical port.
