EXIN EPI Certified Data Centre Specialist Sample Questions (Q39-Q44):

NEW QUESTION # 39
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. 30 Amperes
B. 12 Amperes
C. 60 Amperes
D. 80 Amperes

Answer: A

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 , ext{Ah} imes 0.05 = 30 , ext{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 # 40
It is assumed that EMF shielding material must be installed as the EMF levels coming from the transformer room into the computer room are measured at 100mG. The transformer room is approximately 10 meters away from the computer room and is separated by a corridor. You can assume that no physical issues are present for installing shielding material at any area/location.
Where should you recommend the shielding material to be installed?

A. As close as possible to the computer room
B. It does not matter, either close to the transformer room or the computer room is okay as there is no impact to cost or shielding material performance
C. Shielding is not required to be installed as 100mG is within the acceptable levels for computer rooms
D. As close as possible to the transformer room

Answer: D

Explanation:
EMF shielding is most effective when installed close to the source of the EMF, which in this case is the transformer room. Shielding at the source contains the magnetic fields before they spread, minimizing exposure throughout the facility, including the computer room.
Detailed Explanation:
Placing shielding close to the EMF source minimizes the area impacted by electromagnetic interference, as it reduces the distance over which the EMF can spread. Shielding materials near the source can absorb or redirect EMF, providing the most effective reduction of EMF levels in adjacent spaces, like the data center.
EPI Data Center Specialist References:
EPI data center training advises positioning shielding close to the EMF source to contain fields more effectively and reduce interference in critical areas. This method is more efficient and cost-effective, as it limits the spread of EMF from the point of origin.

NEW QUESTION # 41
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 shall be tightly organized to the rack and trays to avoid movement.
C. Cables should be replaced by busbar trunking.
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 # 42
Do you need to consider bullet (ballistics) protection when designing a data center?

A. Bullet (ballistics) protection is only required when the data center is located in an area with a high crime rate.
B. Bullet (ballistics) protection is only required if the facility is a potential target or the building is in the vicinity of a potential target.
C. Bullet (ballistics) protection is required by ANSI/TIA-942 for all data centers.
D. Bullet (ballistics) protection is required by ANSI/TIA-942 for data centers Rated 3/4.

Answer: B

Explanation:
Bullet (ballistics) protection is typically considered only for data centers that are potential targets or located near such targets. While ANSI/TIA-942 does not specifically require bulletproofing for all data centers, it is prudent to consider it based on location risk assessments, especially if the facility is in a high-risk area or near critical infrastructure that could attract threats.
Detailed Explanation:
Protective measures like bulletproofing depend on the threat landscape and the data center's exposure to risks such as crime or terrorism. Assessments for physical security are typically customized based on location-specific risks rather than being universally required by data center standards.
EPI Data Center Specialist References:
EPI guidelines emphasize customizing physical security measures based on threat assessments, suggesting that bulletproofing is appropriate in specific circumstances where the facility's risk profile justifies additional security measures.

NEW QUESTION # 43
In which stage of the data center life cycle does commissioning take place?

A. Operate/optimize
B. Design
C. Implement
D. Retire

Answer: C

Explanation:
Commissioning occurs during the Implementation stage of the data center life cycle. This phase involves the final testing and verification of systems and equipment to ensure they meet design specifications and operational requirements before the data center goes live.
Detailed Explanation:
The Implement phase includes activities such as installation, configuration, and testing. Commissioning is a crucial step that validates the performance and reliability of all critical systems, including power, cooling, and network infrastructure, to ensure they operate as intended under various conditions. Proper commissioning helps identify and resolve any issues before the data center becomes fully operational.
EPI Data Center Specialist References:
EPI training emphasizes that commissioning is essential for verifying that the data center meets design and performance criteria, aligning with best practices in data center project management to minimize risks and ensure readiness for operation.
