  • Question
  • Which of the following are benefits of VLANs?

    1. They increase the size of collision domains.
    2. They allow logical grouping of users by function.
    3. They can enhance network security.
    4. They increase the size of broadcast domains while decreasing the number of collision domains.
    5. They simplify switch administration.
    6. They increase the number of broadcast domains while decreasing the size of the broadcast domains.

  • Options
  • A. 1 and 5
  • B. 2 and 4
  • C. 1, 3 and 5
  • D. 2, 3 and 6

  • Correct Answer
  • 2, 3 and 6 

    VLANs break up broadcast domains in a switched layer 2 network, which means smaller broadcast domains. They allow configuration by logical function instead of physical location and can create some security if configured correctly.
