What are three data center attributes that impact the selection of a fire protection system? (Choose three.)
The correct answer is A. The presence of a raised floor. Note: This is a "choose three" question, but only Answer A is listed as correct - the complete answer set is most likely A, B, and E. Here's why: A (raised floor) is correct because a raised floor creates a sub-floor plenum that must be protected by the fire suppression system…

Explanation
Note: This is a "choose three" question, but only Answer A is listed as correct - the complete answer set is most likely A, B, and E. Here's why:
A (raised floor) is correct because a raised floor creates a sub-floor plenum that must be protected by the fire suppression system independently - the type and placement of suppression agents (gaseous, sprinkler, etc.) must account for this hidden combustible space.
B (air changes per hour) is correct because high HVAC airflow rates rapidly dilute and exhaust gaseous suppression agents (like FM-200 or CO₂), making them ineffective - system design must account for how quickly the agent will be purged from the space.
E (proximity to other buildings) is correct because nearby structures create external fire exposure risk, influencing whether passive suppression, sprinkler systems, or additional detection redundancy is needed.
C (UPS rated capacity) is a distractor - UPS sizing relates to power continuity, not fire suppression design.
D (double insulated windows) is a distractor - window insulation is a thermal/energy efficiency attribute with no bearing on fire protection systems.
Memory tip: Think "what does fire suppression physically interact with?" - the floor (A), the air (B), and the surrounding environment (E). Electrical capacity (C) and glass type (D) are thermal/power concerns, not fire suppression concerns.
