EXIN EPI Certified Data Centre Specialist Sample Questions (Q51-Q56):

NEW QUESTION # 51
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 500 CFM
  • B. Approximately 1,000 CFM
  • C. Approximately 1,500 CFM
  • D. Approximately 160 CFM

Answer: B

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 # 52
A 5kW (power consumption) server keeps crashing with the message 'temperature too high'.
The intake temperature is measured at 25 °C/77 °F and a relative humidity (RH) level of 50%.
The exhaust temperature is 29 °C/84 °F and 45% RH.
The raised floor is providing an adequate amount of CFM/CMH at a reasonable velocity.
The pressure under the raised floor is approximately 25 Pa/0.1 inch H₂O.
Analyze the situation and indicate what the most likely cause is for this server to crash.

  • A. Dust inside the server causing issues with convection-based heat transfer
  • B. The raised floor pressure is too low and/or the raised floor tile % opening is not adequate
  • C. No cause could be determined as the CFM/CMH of the air conditioning equipment is not stated
  • D. The exhaust temperature is exceeding the ASHRAE recommended values

Answer: A

Explanation:
The server's repeated overheating despite adequate intake and exhaust temperatures suggests that dust buildup inside the server may be impeding heat transfer. Dust accumulation can obstruct airflow within the server, insulate components, and disrupt the convection-based cooling systems that regulate internal temperatures, leading to overheating and potential hardware failures.
Detailed Explanation:
While the intake and exhaust temperatures appear within acceptable ranges, internal dust can reduce airflow and impede cooling efficiency, causing internal components to overheat despite seemingly normal ambient conditions. Regular cleaning and maintenance are critical for preventing dust-related issues, especially in high-powered equipment like a 5kW server.
EPI Data Center Specialist References:
EPI emphasizes regular maintenance to prevent dust buildup in data center equipment. Dust can significantly impact cooling efficiency and lead to overheating, which underlines the importance of routine cleaning for optimal server performance.


NEW QUESTION # 53
The logical overview of the data center looks as pictured. To what TIA-942 Rating is this design made based on electrical only?

  • A. Rating - 4
  • B. Rating - 2
  • C. Rating - 3
  • D. Rating - 1

Answer: A

Explanation:
The electrical design shown in the diagrams represents a TIA-942 Rating-4 configuration. This design includes full redundancy and fault tolerance, as demonstrated by the dual power distribution paths from the utility supply to the critical loads. Each power distribution path is equipped with its own UPS, ensuring that the ICT equipment and mechanical equipment have uninterrupted power in case of any single point of failure.
Detailed Explanation:
A Rating-4 data center requires two independent power paths that are fully redundant and capable of supporting the load independently. In the diagrams:
There are dual feeds from the utility supply, each going through separate transfer switches and power distribution paths.
Both paths have backup sources (+1) and serve critical components through separate UPS systems, providing a completely redundant setup.
The design also includes redundant paths to the mechanical equipment and ICT equipment, which further indicates the fault-tolerant characteristics of a Rating-4 infrastructure.
This setup allows for concurrent maintainability and ensures that no single failure in power distribution or UPS can impact the data center's operation, which is characteristic of the highest Tier/Rated-4 classification.
EPI Data Center Specialist References:
EPI guidelines confirm that TIA-942 Rating-4 requires full redundancy and fault tolerance for electrical infrastructure, ensuring continuous operation even during maintenance or failure events. This design meets all those requirements, thus aligning with Rating-4 standards.


NEW QUESTION # 54
A data center is located in an area where the demand for power is higher than the utility power company is able to deliver. This results in frequent power outages and, therefore, power shedding (scheduled/controlled power shutdown for areas) is frequently applied. The mains power is more than 650 hours/year not available.
What type of generators should be installed?

  • A. A combination of standby-, prime-, and continuous-generators, as the duration of the power outage is unpredictable. The total available capacity of the generators should be at least 500% of the data center load
  • B. Continuous generators should be installed; no N+1 configuration is needed as the generators will run all the time
  • C. Continuous generators should be installed, at least in an N+1 configuration
  • D. Standby generators should be installed in at least an N+1 configuration

Answer: C

Explanation:
In areas with frequent and extended power outages, continuous generators with at least an N+1 configuration are necessary to ensure consistent power availability. Continuous generators are designed for prolonged operation, making them suitable for scenarios where utility power is frequently unavailable, as in this case with outages exceeding 650 hours per year. An N+1 configuration ensures redundancy, which is critical for maintaining uptime in a high-availability data center.
Detailed Explanation:
Continuous generators provide reliable power over long durations, unlike standby generators, which are intended only for short-term use. The N+1 configuration ensures that there is always an additional generator available in case of failure, thus maintaining power supply even if one generator goes offline.
EPI Data Center Specialist References:
EPI best practices recommend continuous generators with redundancy for data centers located in areas with high power instability to maintain reliability and continuous operation.


NEW QUESTION # 55
What precaution shall be taken for cabling leading into an equipment rack when a data center is in a seismic-prone area?

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

Answer: C

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.
