A switch is configured with a single VLAN of 12 for all interfaces. All nodes auto-negotiate at 100 Mb/s full-duplex. What is true if you add an additional VLAN to the switch.

A. The switch will decrease its bandwidth due to overhead.
B. The switch will increase its count of collision domains.
C. The switch will now require a router.
D. The switch will increase its bandwidth due to broadcast domains.

D. The addition of another VLAN will increase the effective bandwidth by adding additional broadcast domains. A router is required to route between VLANs. However, it will not be required if you are logically partitioning the switch via VLANs.
