문제1

You are changing the design of the fire suppression system for your computer room from a halocarbon fire suppression system into an inert-based fire suppression system. Could you use the same formula to calculate the gas content for the gas?

A. No, there is a significant difference in the formula for the different types of fire suppression gases.

B. Yes, as long as you change the 'S' factor of the formula to reflect the gas type used.

C. Yes, as long as you take the difference between the net and gross volume into account.

D. Yes, as long as you use the same units of measure, i.e., kg/m³ or lbs/ft³.

문제2

What is the calculation for the desired attenuation factor for shielding material?

A. You do not have to calculate the attenuation factor for shielding material as it always has the same attenuation

B. A = 20 log (R / M)
Where A is Attenuation R is the real value measured M is the maximum acceptable value

C. A = M / R
Where A is Attenuation M is the maximum acceptable value R is the real value measured

D. A = 20 log (M / R)
Where A is Attenuation M is the maximum acceptable value R is the real value measured

문제3

The noise levels in the data center are approximately 91 dB (A).
Do employers need to take precautions?

A. As long as the data is compliant to ISO/IEC 27001 it is acceptable.

B. There are no regulations regarding noise levels inside a building. Regulations only apply to noise pollution outside of the building.

C. Yes, since it is mandated by regulations.

D. No, anything less than 100 dB (A) is acceptable.

문제4

A computer room needs to be fitted out with a gas-based fire suppression system. The computer room will be a high-density data center with about 30% of the racks being closed circuit cooling blade-center racks.
Should the supplier of the fire suppression system be informed on the design of the racks?

A. Only when the rack height obstructs a potential fire suppression release point.

B. No, cooling and design of racks have no influence on the fire suppression system design.

C. Yes, the design of the racks has an influence on the fire suppression system design.

D. Only when the racks might block access to the fire panel.

문제5

You are installing new copper cabling.
What is the advantage or disadvantage of choosing pre-terminated category 6 or 6A cabling?

A. Pre-terminated cabling has a higher fire rating.

B. Pre-terminated cabling makes ordering of the copper cables more complex, as you need to know in advance on which side the male or female connector needs to be located.

C. Pre-terminated cabling is already factory tested and saves installation time.

D. There is no advantage as most new copper cabling network designs are based on category 3 or 5E for horizontal cabling.

문제6

You are allowed to use a calculator for this question.
A computer room has a net volume of approximately 2,500 m³ / 88,287 ft³.

The required design concentration is 7%.
The S-Factor is 0.1359 (metric) / 1.885 (imperial).
Calculate the amount of gas required for this computer room based on FM200. What is the correct weight?

A. Approximately 1,390 kg / 3,000 lbs

B. Approximately 820 kg / 1,800 lbs

C. Approximately 410 kg / 900 lbs

D. Approximately 1,640 kg / 3,600 lbs
