EXIN EPI Certified Data Centre Specialist Sample Questions (Q41-Q46):

NEW QUESTION # 41
What is a potential disadvantage of using water mist as a fire extinguishing system?

  • A. It extracts oxygen from the air creating a potential risk for humans inside the computer room
  • B. It only uses 10% of the water normally used in a water-based fire suppression, which might not be enough to suppress the fire
  • C. It has droplets that are too small (100-120 microns) so it can only be used for small fires
  • D. It will rapidly increase the humidity level in the data center, which can cause a potential risk for the operation of the equipment

Answer: D

Explanation:
A potential disadvantage of using a water mist fire suppression system is that it can rapidly increase the humidity within the data center, which may pose risks to sensitive electronic equipment. Excessive humidity can lead to condensation, which could damage electronics and lead to short circuits or corrosion over time.
Detailed Explanation:
Water mist systems use fine droplets to suppress fires by cooling and displacing heat. However, the moisture generated may raise the humidity level to the point where it exceeds safe operational limits for IT equipment. Therefore, while water mist systems are effective in fire suppression, they may not be ideal in environments where high humidity could damage sensitive equipment.
EPI Data Center Specialist References:
EPI guidelines advise considering the impact of humidity from fire suppression systems, particularly in environments housing electronic equipment. It's essential to weigh the benefits of fire suppression against potential risks to operational equipment when choosing suppression methods.


NEW QUESTION # 42
From the options indicated, what is the correct starting point for the raised floor installation?

  • A. Point A
  • B. Point B
  • C. Point D
  • D. Point C

Answer: B

Explanation:
When installing a raised floor, the best starting point is typically from the farthest corner away from the entrance, in this case, Point B. This method allows for the floor installation to progress towards the entrance, ensuring that workers can avoid walking over the newly installed tiles, thus minimizing the risk of damage and maintaining cleanliness during installation.
Detailed Explanation:
Starting at the farthest corner (Point B) and working towards the entrance (Point A) is a standard practice in raised floor installation. This approach ensures that installers do not walk over freshly laid tiles, which could lead to shifting or misalignment. Additionally, it allows for more controlled placement and alignment, as well as convenient egress when installation is complete.
EPI Data Center Specialist References:
EPI guidelines for raised floor installation emphasize beginning at the farthest point from the entrance and working back towards it, which aligns with industry best practices for efficiency and quality assurance. This method reduces potential damage and supports precise alignment across the floor area.


NEW QUESTION # 43
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. Yes, as long as you take the difference between the net and gross volume into account.
  • B. No, there is a significant difference in the formula for the different types of fire suppression gases.
  • C. Yes, as long as you use the same units of measure, i.e., kg/m³ or lbs/ft³.
  • D. Yes, as long as you change the 'S' factor of the formula to reflect the gas type used.

Answer: B

Explanation:
The formula used to calculate the gas content differs significantly between halocarbon and inert-based fire suppression systems. Halocarbon systems function by absorbing heat, while inert systems work by reducing oxygen levels. Due to these differences in fire suppression mechanisms, distinct formulas are applied, factoring in the specific properties of each gas type and the required concentration levels.
Detailed Explanation:
Halocarbon systems like FM200 require a formula that accounts for the concentration needed for cooling, while inert gases like nitrogen or argon need a formula that calculates the volume based on oxygen displacement. As the design concentration and characteristics of these gases differ, it's essential to use the correct formula specific to the gas type.
EPI Data Center Specialist References:
EPI recommends consulting the specific design requirements and formulas provided by each gas manufacturer when switching fire suppression systems to ensure the correct amount of gas is deployed for effective fire suppression.


NEW QUESTION # 44
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. No, anything less than 100 dB (A) is acceptable.
  • D. Yes, since it is mandated by regulations.

Answer: D

Explanation:
In a data center with noise levels of 91 dB (A), employers are indeed required to take precautions to protect personnel, as this level exceeds commonly accepted safety thresholds for occupational noise exposure. Regulations, such as those from the Occupational Safety and Health Administration (OSHA) or similar agencies, mandate specific controls and protections for environments with high noise levels.
Detailed Explanation:
Noise levels above 85 dB (A) typically trigger requirements for hearing conservation programs. At 91 dB (A), steps like providing ear protection, conducting regular noise assessments, and possibly implementing engineering controls to reduce noise should be taken. Extended exposure to such levels can lead to hearing loss, so regulatory compliance ensures both immediate and long-term protection for personnel.
EPI Data Center Specialist References:
EPI guidelines for data center safety address noise exposure as part of the environmental safety measures. EPI recommends adhering to local occupational health regulations, as excessive noise can harm personnel and affect operational efficiency due to potential health hazards.


NEW QUESTION # 45
The building in which the computer room is housed is required to have a sprinkler system. The building is therefore equipped with a wet pipe system.
What action, if any, should you recommend for the computer room?

  • A. Replace the wet pipe system with a pre-action system.
  • B. Replace the wet pipe system with a dry pipe system.
  • C. Maintain the current wet pipe system.
  • D. Replace the wet pipe system with a deluge system.

Answer: A

Explanation:
In computer rooms, replacing a wet pipe system with a pre-action system is advisable. Pre-action systems provide additional protection by requiring two triggers (e.g., heat and smoke) before water is released, minimizing the risk of accidental discharge and water damage, which is crucial for safeguarding sensitive IT equipment.
Detailed Explanation:
Wet pipe systems contain water in the pipes at all times, which poses a higher risk of accidental discharge. Pre-action systems, however, only fill the pipes with water upon detection of a fire, reducing the risk of water-related damage due to leaks or malfunctions. This approach is considered best practice for environments housing sensitive electronic equipment.
EPI Data Center Specialist References:
EPI advises using pre-action fire suppression in data centers to reduce risks associated with accidental water release, providing a safer and more controlled fire response that better protects critical infrastructure.
