One of the workgroup switches in your organization is configured with all ports assigned to VLAN 3, where all ports are configured as full-duplex Fast Ethernet. What is most likely to happen when switch ports are added to a new VLAN on this switch?
  1. This will lead to more collision domains.
  2. IP address utilization will be more efficient.
  3. One more broadcast domain will be created.
  4. The probability of a switching loop will increase.
Explanation
Answer - C - Adding switch ports to a new VLAN will create an additional broadcast domain.

Key Takeaway: Controlling broadcast domains throughout the network is important to improve the efficiency of a network. Routers operating at Layer 3 of the OSI model provide broadcast domain segmentation for each interface. Switches can also provide broadcast domain segmentation using a VLAN. VLAN is a group of switch ports within single or multiple switches, which is defined by the switch as a single broadcast domain. It groups devices connected into logical broadcast domains.
