Answer A https://networklessons.com/cisco/ccna-routing-switching-icnd1-100-105/voice-vla First, we have to create the two VLANs: SW1(config)#vlan 100 SW1(config-vlan)#name COMPUTER SW1(config-vlan)#exit SW1(config)#vlan 101 SW1(config-vlan)#name VOIP SW1(config-vlan)#exit Now we can configure the interface: SW1(config)#interface GigabitEthernet 0/1 SW1(config-if)#switchport mode access SW1(config-if)#switchport access vlan 100 SW1(config-if)#switchport voice vlan 101 SW1(config-if)#exit We configure the interface in access mode and use VLAN 100 for the computer. The switchport voice vlan command tells the switch to use VLAN 101 as the voice VLAN.

My concern here is the part in the question stated that All Vlans are present "All VLANs are present in the VLAN database" If that is the case shouldn't we use add?

There was a question earlier where the correct answer was a truck and not access. This question clears up that confusion. Voice Vlan should be an access port.

voice vlan is always access port, any option of voice vlan being trunk should get eliminated at first !!
