Which building feature is required under Level 3 survivability?

• A. A fully sprinklered building
• B. A redundant central control room
• C. Separate power transfer switch
• D. Dedicated battery room

Answer: (A)

Level 3 survivability hinges on maintaining safety and keeping vital systems functional during a fire-through automatic fire protection. A fully sprinklered building is the strongest match because sprinklers automatically suppress or slow a fire, limit heat and smoke, and help protect escape routes and life safety systems even as conditions worsen. The other features—redundant control rooms, separate power transfer switches, or a dedicated battery room—improve reliability, but they are not the specific requirement that defines Level 3 survivability.
