How do data and voice VLANs coexist on the same access port when a PC is connected behind an IP phone?

Both data and voice traffic are tagged with their respective VLANs

Voice traffic is untagged, and data traffic is tagged

Both data and voice traffic are untagged in the same VLAN

Data traffic is untagged in the access VLAN, and voice traffic is tagged with the voice VLAN

On a Cisco switch port connected to an IP phone, what is the purpose of the 'switchport voice vlan 50' command?

It assigns the data traffic from the PC to VLAN 50

It creates a new VLAN named 'voice'

It assigns the voice traffic from the phone to VLAN 50

A network has two switches connected via a trunk. The trunk is configured with 'switchport mode trunk' and the native VLAN is left at the default. An administrator notices that VLAN 1 traffic is being forwarded across the trunk, but the security policy requires that VLAN 1 not be used for any user traffic. The administrator wants to prevent VLAN 1 from being carried on the trunk while still allowing other VLANs. Which configuration change achieves this?

Configure 'switchport trunk allowed vlan remove 1' on both ends of the trunk.

Change the native VLAN to VLAN 2 on both ends of the trunk.

Set the trunk to 'switchport mode dynamic desirable' on both ends.

Disable DTP on both ends of the trunk.

Which command configures a switch port as a trunk port using 802.1Q tagging?

An administrator is troubleshooting why a host in VLAN 5 cannot reach a host in VLAN 6. Both hosts are connected to the same switch. The administrator runs 'show vlan brief' and sees both VLANs listed. Which additional verification step would BEST confirm whether interVLAN routing is configured?

Run 'show ip route' on the switch to see if routes for both VLAN subnets exist.

Run 'show interfaces trunk' to check if the ports are trunking.

Run 'show mac address-table' to verify the hosts are in the same VLAN.

Run 'show vlan brief' again to confirm the VLANs are active.
