EXIN EPI Certified Data Centre Specialist Sample Questions (Q21-Q26):

NEW QUESTION # 21
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 replaced by busbar trunking.
B. Cables shall be tightly organized to the rack and trays to avoid movement.
C. Cables can be organized in any way as it is not important.
D. Cables should be loosely organized to allow for movement and be latched at the connectors.

Answer: B

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.

NEW QUESTION # 22
The temperature in the computer room is being increased from 18°C/64°F to 27°C/81°F.
What is the impact, if any, on the amount of gas required to suppress a fire assuming the gas is a Halocarbon?

A. The amount of gas required will not change
B. The amount of gas required will be higher
C. The amount of gas required will be lower
D. The change to the amount of gas cannot be determined without knowing the change in humidity as well

Answer: C

Explanation:
With Halocarbon fire suppression systems, as the temperature increases, the amount of gas required for effective suppression decreases. This is because Halocarbon agents are stored as a liquid and discharge as a gas, expanding more at higher temperatures. As a result, less agent is needed at higher room temperatures to achieve the desired concentration for fire suppression.
Detailed Explanation:
Halocarbons rely on specific volumetric concentrations to suppress fires. Higher temperatures cause the agent to expand more rapidly, effectively filling the protected area with less agent needed to reach the required concentration. This is in contrast to some other gases, where temperature changes might not have the same effect on discharge quantities.
EPI Data Center Specialist References:
EPI data center training on fire suppression indicates that understanding the physical properties of agents like Halocarbons is key for correct system sizing. As the temperature rises, the gas expands more readily, thus requiring adjustments in the amount needed for effective coverage.

NEW QUESTION # 23
The noise levels in the data center are approximately 91 dB (A).
Do employers need to take precautions?

A. There are no regulations regarding noise levels inside a building. Regulations only apply to noise pollution outside of the building.
B. No, anything less than 100 dB (A) is acceptable.
C. Yes, since it is mandated by regulations.
D. As long as the data is compliant to ISO/IEC 27001 it is acceptable.

Answer: C

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 # 24
What is the main reason to install Earth Leakage protection?

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

Answer: B

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.

NEW QUESTION # 25
A data center has its own power supply from the public utility and receives chilled water supply from the building owner.
What needs to be taken into consideration when calculating the PUE?

A. Nothing, as the chiller plant in the building also uses electrical power
B. PUE calculations are not possible in shared buildings
C. You will need to take a weight factor of 0.4 for district chilled water into consideration
D. You will need to take the value for COP of the chiller plant into consideration

Answer: C

Explanation:
When calculating Power Usage Effectiveness (PUE) in a data center that uses chilled water from an external source, like from a building owner, a weight factor for district chilled water must be applied. This is because PUE calculations aim to measure the energy efficiency of the data center's own operations, and external utilities like district chilled water aren't directly powered by the data center. A weight factor of 0.4 is typically used to account for the energy consumed to produce and deliver the chilled water, reflecting the indirect impact on the data center's total energy consumption.
Detailed Explanation:
PUE is calculated as the ratio of the total facility energy to the IT equipment energy. If the cooling is provided by an external chilled water source, it's necessary to adjust the calculations to accurately reflect the energy impact. By incorporating the 0.4 weight factor, data centers can calculate a more accurate PUE, aligning with standard methods and industry best practices.
EPI Data Center Specialist References:
EPI training on PUE highlights the importance of adjusting for external energy sources, such as district cooling, in the calculations. This ensures that PUE values remain accurate and comparable across different data centers, even when external utilities are used.
