Selected Answer: D
Configure VTP & 802.1q on inter-switch connections with native VLAN 100 (Management Subnet) & configure VLSM for the IP address range when you want to centrally manage switches & segments in separate broadcast domains if supervisor asks for a VLAN 100 to be the management subnet & all of the switches must share VLAN information by first using VLAN 1 that uses a single private IP address range with a 24-bit mask. The 801.q standard is used to define VLAN tagging (or port tagging) for Ethernet frames and the accompanying procedures to be used by bridges and switches in handling such frames. Traffic should be properly tagged when combined over a single trunk port to ensure they are not sent to the wrong VLAN by mistake. If VLAN tagging is not enabled, all of the VLAN traffic will be sent to the native or default VLAN, VLAN 1. By default, VLAN 1 is enabled and all unused ports are assigned to it.

From what i've seen most VOIP phones have a ethernet passthrough so you can run a cat6 to the phone than out the phone to the desktop.

The correct answer is D. VLAN tags. VLAN (virtual LAN) tags are used to identify packets as belonging to a particular VLAN. VLANs are used to segment a network into logical sub-networks, and each VLAN is assigned a unique VLAN tag. If the VLAN tag is not configured correctly, the computer may not be able to access network resources.

Usually network engineers set-up VoIP with their own VLAN. In this question, the VLAN is correct on the Phone, but not the actualy desktop. Reason why the user can not access local resources.

Well, in a typical setup, the phone would have a (voice) VLAN configured, not the computer. It is possible, that the computer has the voice VLAN ID assigned, which would explain that network resources are unavailable.
