出題：3

Do you need to consider blast protection when designing a data center?

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.

出題：5

The pipes of a VESDA smoke detection system are installed at the air intake of the air conditioner inside the computer room.
Is this a good practice from an early smoke detection point of view?

A. No, the piping should be installed at the air exhaust of the air conditioner, as there can also be a fire inside the air conditioner itself.

B. Yes, as this reduces the amount of piping to be installed in the data center, as all air will go through the air conditioner.

C. It depends on the type of gas-based fire suppression which will be installed.

D. No, it will give a longer reaction time for the smoke detection system and there might also be bypass airflow.

出題：6

It is assumed that EMF shielding material must be installed as the EMF levels coming from the transformer room into the computer room are measured at 100mG. The transformer room is approximately 10 meters away from the computer room and is separated by a corridor. You can assume that no physical issues are present for installing shielding material at any area/location.
Where should you recommend the shielding material to be installed?

A. As close as possible to the computer room

B. As close as possible to the transformer room

C. It does not matter, either close to the transformer room or the computer room is okay as there is no impact to cost or shielding material performance

D. Shielding is not required to be installed as 100mG is within the acceptable levels for computer rooms
