A. It can only be used in computer rooms where you have sufficient positive pressure.
B. It can only be used in computer rooms which have sufficient air changes per hour.
C. The gas containers need to be close to the hazard area.
D. It can only be used in non-continuous occupied areas.
A. Yes, if the data center is a potential target or the building is located within the vicinity of (close by) a potential target.
B. No, blast protection is not a requirement of ANSI/TIA-942.
C. Yes, blast protection is a requirement of ANSI/TIA-942.
D. No, there is no reason for implementing blast protection as nobody can predict the impact of a bomb explosion.
A. No; bullet protection is not a requirement of ANSI/TIA-942
B. Yes, but only when the data center is built in an area with a high criminality rate or with a risk of terrorist attacks
C. Yes, bullet protection is a requirement of ANSI/TIA-942 for Rated-3/4 data centers
D. No, there is no reason for implementing bullet protection as you cannot predict the type of weapons that might be used

A. Cables should be replaced by busbar trunking.
B. Cables shall be tightly organized to the rack and trays to avoid movement.
C. Cables should be loosely organized to allow for movement and be latched at the connectors.
D. Cables can be organized in any way as it is not important.
A. Optical fiber cabling should always be positioned on top of the copper cabling in the same cable tray to avoid damage to the sensitive optical fiber.
B. Copper data cabling should not be placed in metal cable trays.
C. To maintain minimum separation from power and ensure that the fire detection and suppression systems are not hindered.
D. All cabling should make sharp bends directly into the rack to avoid usage of additional space and blocking the airflow on top of the rack.

A. Yes, but only if the data center is located in Zone 0 with no or little seismic activity
B. Yes, a raised floor needs to be installed tight to the perimeter to prevent air leakage
C. No, to avoid damage to the raised floor due to building and hygrothermal movement
D. No, but this applies only to raised floors with a height of over 90 cm (3 ft)
