Jason Dion's Network+ Course Practice Test

Raised floors create an underfloor space that hides and routes cabling while keeping it accessible for maintenance. This design keeps power and network cables organized and out of the way, making it easier to pull and manage cables to racks without clutter on the floor. The underfloor plenum can also be used to distribute cold air up to the equipment, aiding cooling, but the raised floor is not the cooling system itself—air is moved by the data center’s HVAC setup, with the floor simply helping air flow. It has nothing to do with increasing wireless signal or with user authentication. So the best fit is hiding and routing cabling under the floor while keeping it accessible, with the added benefit of airflow management for cooling.
