Which of the following is a benefit of using raised floors with specially configured tiles in a server room?
The correct answer is A. To provide for heat dissipation using forced air through the sub-floor. Raised floors in server rooms use perforated or specially configured tiles to direct pressurized cool air from the sub-floor plenum upward into server cold aisles for targeted heat dissipation.

Why each option
Raised floors in server rooms use perforated or specially configured tiles to direct pressurized cool air from the sub-floor plenum upward into server cold aisles for targeted heat dissipation.
Raised floor systems create a sealed plenum beneath the floor that is pressurized with cool air delivered by CRAC or CRAH units. Perforated tiles or tiles with adjustable dampers are positioned in cold aisles to release this forced air directly into server front intakes, enabling front-to-back airflow management and efficient removal of heat without mixing with hot exhaust air from the hot aisles.
Liquid cooling systems deliver coolant through pipes routed directly to rack-mounted cooling units or server chassis - they are not a primary function of raised floor tile configurations.
Baffles and shrouds are airflow management components installed inside server chassis or within rack enclosures to guide airflow through components, not devices housed in the sub-floor plenum.
Redundant power supplies are components internal to servers or housed in rack-mounted PDUs, not equipment stored beneath raised floor tiles.
