Cisco 200-125 Exam

A switch is configured with all ports assigned to VLAN 2. In addition, all ports are configured as full-duplex FastEthernet. What is the effect of adding switch ports to a new VLAN on this switch?

  • A. The additions will create more collisions domains.
  • B. An additional broadcast domain will be created.
  • C. More bandwidth will be required than was needed previously.
  • D. IP address utilization will be more efficient.
Answer: Option B.
Explanation: 

We have the same number of ports on the switch, and each port is its own collision domain, so the number of collision domains remains unchanged. However, each VLAN is its own broadcast domain, so the number of broadcast domains will increase (B).
