Question

A network technician is in the process of setting up a university lab. The lab requires 23 workstations; the workstations will need to be segregated from the rest of the network, with no wireless access, while limiting collisions. Which of the following will satisfy these requirements while being the LEAST expensive?

Options

  • ABridge
  • BSwitch
  • CRouter
  • DHub

Explanation

A switch operates at Layer 2 and creates individual collision domains per port, effectively eliminating collisions. It is a wired device (no wireless), and VLANs can be used to segregate the lab from the rest of the network. A hub (D) is cheaper but does not limit collisions - all ports share one collision domain, making it unsuitable. A router (C) can segment networks but is more expensive and is overkill for a simple LAN lab. A bridge (A) is older technology and cannot efficiently handle 23 ports. The switch is the best cost-performance balance.
