A switch is configured with all ports assigned to vlan 2 with full duplex FastEthernet to segment existing departmental traffic. What is the effect of adding switch ports to a new VLAN on the switch?

The correct answer to this question is D - An additional broadcast domain will be created.
Explanation: A broadcast domain is a logical division of a computer network, in which all devices can reach each other by broadcast at the data link layer. Broadcast traffic is generated by network devices to communicate with all devices on a network. Each VLAN represents a separate broadcast domain, so if new ports are added to a new VLAN, an additional broadcast domain will be created.
In the given scenario, all ports of the switch are assigned to VLAN 2. Therefore, all devices connected to those ports are in the same broadcast domain. If new ports are added to a new VLAN, then those devices will be separated from the devices in VLAN 2, and a new broadcast domain will be created.
Option A, "More collision domains will be created," is incorrect because collision domains are created in half-duplex networks where multiple devices share the same communication medium. In full-duplex networks, each port has its own collision domain.
Option B, "IP address utilization will be more efficient," is incorrect because adding new VLANs does not affect IP address utilization. IP addresses are assigned to devices, not VLANs.
Option C, "More bandwidth will be required than was needed previously," is incorrect because adding new VLANs does not increase the bandwidth requirements. Bandwidth is determined by the devices and applications that use the network, not by the number of VLANs.
