Question

Refer to the exhibit. All VLANs are present in the VLAN database. Which command sequence must be applied to complete the configuration? A. B. C. D.

Options

Ainterface FastEthernet0/1 switchport trunk native vlan 10 switchport trunk allowed vlan 10,15
Binterface FastEthernet0/1 switchport mode trunk switchport trunk allowed vlan 10,15
Cinterface FastEthernet0/1 switchport mode access switchport voice vlan 10
Dinterface FastEthernet0/1 switchport trunk allowed vlan add 10 vlan 10 private-vlan isolated

Explanation

Option C is correct because the exhibit shows a configuration involving a Cisco IP phone connected to a switch port, which requires the port to be set as an access port with a separate voice VLAN. The 'switchport mode access' command sets the port as an access port for data traffic, and 'switchport voice vlan 10' enables the voice VLAN so the IP phone can tag its traffic on VLAN 10 while the PC connected through the phone uses the access VLAN 15. This is the standard Cisco configuration for ports connecting to IP phones.
