EXIN EPI Certified Data Centre Specialist Sample Questions (Q42-Q47):

NEW QUESTION # 42
You are allowed to use a calculator for this question. The total power consumption of the ICT equipment in a rack is 6 kW. The equipment is traditional ICT equipment with a Delta-T of approximately 11 °C / 20 °F. Calculate the approximate CFM required to cool the equipment in the rack.

  • A. Approximately 160 CFM
  • B. Approximately 500 CFM
  • C. Approximately 1,000 CFM
  • D. Approximately 1,500 CFM

Answer: C

Explanation:
To calculate the cooling airflow requirement for ICT equipment, you can use the formula:
CFM=Power (kW)×3160ΔT(°F)text{CFM} = frac{text{Power (kW)} times 3160}{Delta T (text{°F})}CFM=ΔT(°F)Power (kW)×3160​ For equipment consuming 6 kW with a Delta-T of 20°F:
CFM=6×316020=948≈1,000 CFMtext{CFM} = frac{6 times 3160}{20} = 948 approx 1,000 , text{CFM}CFM=206×3160​=948≈1,000CFM Detailed Explanation:
This formula provides an estimate of the cubic feet per minute (CFM) of air required to cool the equipment based on its power consumption and the temperature difference (Delta-T) between intake and exhaust. The Delta-T represents the cooling effectiveness of the airflow.
EPI Data Center Specialist References:
EPI recommends using this calculation for determining airflow requirements in data centers, ensuring that cooling systems are adequately sized to maintain equipment within safe temperature limits.


NEW QUESTION # 43
You are allowed to use a calculator for this question. A battery bank is rated at a total capacity of 600 Ah. Calculate how much charging current the rectifier should be able to supply as charging current.

  • A. 80 Amperes
  • B. 30 Amperes
  • C. 60 Amperes
  • D. 12 Amperes

Answer: B

Explanation:
To determine the charging current for a battery bank, a general rule of thumb is that the charging current should be 5% of the total battery capacity. For a battery rated at 600 Ah, this calculation would be:
600 Ah×0.05=30 Amperes600 , text{Ah} times 0.05 = 30 , text{Amperes}600Ah×0.05=30Amperes This ensures the battery is charged efficiently without overloading the rectifier or risking battery damage.
Detailed Explanation:
Battery charging current is typically set as a percentage of the battery's capacity to balance effective charging with longevity and safety. A 5% charging rate is standard for lead-acid batteries, which would be 30 Amperes for a 600 Ah battery bank.
EPI Data Center Specialist References:
EPI standards recommend calculating charging currents based on a percentage of the battery capacity to ensure safety and efficiency, aligning with best practices for battery management in data centers.


NEW QUESTION # 44
From the options indicated, what is the correct starting point for the raised floor installation?

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

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 # 45
A computer room with a raised floor has been designed with racks in a hot/cold aisle setup.
What should you recommend for the placement of down-flow air conditioners?

  • A. Air conditioner placement has no influence on cooling effectiveness and efficiency. Hence, they can be placed at any convenient location.
  • B. Air conditioners perpendicular to (at the end of the row of) the Cold-Aisle
  • C. Air conditioners should always be placed at both sides of each row of racks
  • D. Air conditioners perpendicular to (at the end of the row of) the Hot-Aisle

Answer: B

Explanation:
In a hot/cold aisle configuration, placing down-flow air conditioners perpendicular to the cold aisle ensures that cool air is directed efficiently into the cold aisles where server intakes are located. This layout allows for optimal cooling performance by aligning the airflow directly with the equipment intakes, minimizing hot spots and enhancing cooling efficiency.
Detailed Explanation:
With a raised floor design, cold air from the air conditioners is supplied into the cold aisle, where server intakes are located. Positioning the air conditioning units perpendicular to the cold aisles ensures that cool air is delivered directly into these aisles, preventing air mixing and optimizing cooling. This setup takes full advantage of the airflow management strategy inherent to the hot/cold aisle configuration.
EPI Data Center Specialist References:
EPI guidelines on cooling emphasize that down-flow air conditioners should be positioned to maximize the effectiveness of cold aisle delivery, which improves cooling efficiency and helps maintain consistent temperatures across server racks.


NEW QUESTION # 46
What precaution shall be taken for cabling leading into an equipment rack when a data center is in a seismic-prone area?

  • A. Cables should be loosely organized to allow for movement and be latched at the connectors.
  • B. Cables can be organized in any way as it is not important.
  • C. Cables should be replaced by busbar trunking.
  • D. Cables shall be tightly organized to the rack and trays to avoid movement.

Answer: D

Explanation:
In seismic-prone areas, cables should be tightly secured to racks and cable trays to minimize movement during seismic activity. Properly securing the cables prevents them from being damaged due to excessive motion, which could lead to outages or damage to connected equipment.
Detailed Explanation:
Loose cables can be vulnerable to shaking or sudden jolts during an earthquake, increasing the risk of disconnection or damage. By tightly organizing and securing cables, you ensure they remain in place, even during significant movement, thereby maintaining connection integrity and reducing the risk of physical damage.
EPI Data Center Specialist References:
EPI training includes considerations for data centers in seismic zones, advising that cables be firmly anchored to support structures to reduce movement and mitigate potential damage during seismic events.
