EXIN EPI Certified Data Centre Specialist Sample Questions (Q46-Q51):

NEW QUESTION # 46
When installing a raised floor, can we use a spirit level bar to level the floor?

  • A. Yes, spirit level bars can be used as long as their length is longer than 60 cm/2 ft (the size of a typical raised floor tile).
  • B. Yes, but spirit level bars can only be used in the vertical plane.
  • C. No, because using a spirit level bar, a measurement error will be transferred from pedestal to pedestal.
  • D. Yes, using a spirit level bar for raised floors higher than 40 cm is preferred.

Answer: C

Explanation:
A spirit level bar should not be used for leveling a raised floor, as measurement errors are likely to propagate from one pedestal to the next. Spirit levels can introduce cumulative errors, leading to uneven floors, particularly in large installations where precise leveling is critical.
Detailed Explanation:
Using a laser level or a precision leveling device is recommended to ensure accuracy across all floor tiles. Spirit levels, while adequate for short spans, can transfer small inaccuracies from one pedestal to another, which can cause alignment issues and floor instability over time.
EPI Data Center Specialist References:
EPI data center guidelines discourage the use of spirit levels for raised floors. Instead, they advocate for precision tools like laser levels that ensure consistency and accuracy in large-scale installations, aligning with best practices for raised floor construction.


NEW QUESTION # 47
The UPS of a data center, with an ANSI/TIA-942 Rating-4, is installed with the rectifier connected to power feed A and the bypass/reserve line input connected to power feed B.
To which feed will the output of the UPS be synchronized?

  • A. Feed B
  • B. Feed A
  • C. The UPS will not synchronize to any of the feeds but use an internal clock to set the output voltage and frequency
  • D. Depends on the setting of the UPS, as the UPS can normally be set to either feed

Answer: D

Explanation:
For a UPS system in a Rating-4 data center, the synchronization of output can indeed depend on the specific settings of the UPS. Generally, such systems allow for flexible configuration where the output can be synchronized to either power feed A or B, depending on which feed is preferred for stability or redundancy purposes.
Detailed Explanation:
In dual-feed setups, such as those in high-redundancy data centers, the UPS can be set to synchronize with either feed. This ensures that the UPS maintains continuity in case one feed becomes unstable or fails. The flexibility to choose synchronization to either feed enhances the resiliency and reliability of power supply, which is critical in Tier IV (Rating-4) facilities where uptime is paramount.
EPI Data Center Specialist References:
The EPI Data Center Specialist course underscores the importance of configurable UPS systems in Rating-4 data centers, where redundancy and continuous power are critical. By allowing synchronization to either feed, the UPS can maintain the highest level of reliability, which aligns with the rigorous standards expected in such environments.


NEW QUESTION # 48
In order to save energy, you are going to install an automated system to switch off lights. What should be taken into consideration when installing such a system?

  • A. The system should not be based on motion detection as the lights might suddenly switch off while staff is still at work.
  • B. Security guards should perform regular inspections verifying the system works.
  • C. It is not advisable to use such a system since it will reduce the lifetime of LED lighting.
  • D. At all times, the levels should allow for security cameras to function properly.

Answer: D


NEW QUESTION # 49
Which formula is correct?

  • A. Phase-to-Neutral Voltage = Phase-to-Phase voltage /1.732
  • B. Phase-to-Neutral Voltage = Phase-to-Phase voltage * 1.732
  • C. Phase-to-Neutral Voltage = (Phase-to-Phase voltage * 1.732) / Phase-to-Neutral Voltage
  • D. Phase-to-Neutral Voltage = Phase-to-Neutral voltage * 1.732

Answer: A

Explanation:
The correct formula for calculating Phase-to-Neutral Voltage in a three-phase power system is Phase-to-Neutral Voltage = Phase-to-Phase Voltage / 1.732. This formula applies to balanced three-phase systems, where 1.732 (or √3) represents the relationship between line-to-line and line-to-neutral voltages.
Detailed Explanation:
In three-phase systems, Phase-to-Phase Voltage is higher than Phase-to-Neutral Voltage by a factor of √3. Dividing the phase-to-phase voltage by 1.732 gives the phase-to-neutral voltage, which is critical for understanding power distribution in three-phase electrical systems commonly found in data centers.
EPI Data Center Specialist References:
EPI electrical training highlights the importance of knowing these calculations for designing and maintaining balanced power systems, which are essential for stable and efficient data center operations.


NEW QUESTION # 50
What is the main reason to install Earth Leakage protection?

  • A. Protection against lightning strikes
  • B. Improvement of the data center grounding/earthing system
  • C. Protection of human lives
  • D. Protection of ICT equipment against high-frequency noise currents

Answer: C

Explanation:
Earth Leakage Protection is primarily installed to protect human lives by detecting and disconnecting power when a fault current flows to the ground. This type of protection is essential to avoid electrical shock hazards that could occur when insulation fails, or equipment is improperly grounded.
Detailed Explanation:
Earth leakage currents can occur due to insulation faults or accidental contact with live parts. Earth Leakage Protection systems, such as Residual Current Devices (RCDs), quickly detect these faults and disconnect the circuit to prevent harm to personnel. This is especially crucial in environments like data centers where high-powered equipment is continuously running and any electrical fault can pose significant safety risks.
EPI Data Center Specialist References:
EPI emphasizes that human safety is paramount in data center operations. Proper grounding and leakage protection are fundamental safety measures, and EPI guidelines align with this focus, underscoring the importance of protecting personnel from electrical hazards through appropriate safety systems.
