EXIN EPI Certified Data Centre Specialist Sample Questions (Q27-Q32):

NEW QUESTION # 27
What is the minimum requirement for the power feeds to the building for a Rated-3 data center based on the ANSI/TIA-942 standard?

A. Two feeds coming from two different substations, one power company is not acceptable
B. Two feeds coming from two different substations, one power company is acceptable
C. One feed from one substation split over two separated distribution boards in separate rooms
D. Two feeds entering the data center building from one substation

Answer: B

Explanation:
The minimum requirement for power feeds to a Rated-3 data center according to ANSI/TIA-942 is to have two independent power feeds, which can come from two different substations provided by the same power company. This ensures redundancy and concurrent maintainability, as each feed can support the load independently during maintenance or failure of the other.
Detailed Explanation:
The separation by two substations ensures resilience in case of a localized outage or substation maintenance, aligning with Rated-3 requirements for uninterrupted operation. ANSI/TIA-942 permits these feeds from a single utility provider as long as they are supplied from distinct substations.
EPI Data Center Specialist References:
EPI underscores the importance of dual power feeds from separate substations for Rated-3 facilities, highlighting that the ability to draw from different substations aligns with redundancy requirements for high availability.

NEW QUESTION # 28
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 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 replaced by busbar trunking.

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 # 29
The electrical diagram of the data center shows the following UPS configuration and has a load of 80 kW.
What is the set-up in this data center?

A. 2(N+1)
B. (N+1)-(N+1)
C. 2+N+1
D. N+N(+1)

Answer: A

Explanation:
A 2(N+1) configuration implies two independent UPS systems, each with N+1 redundancy. This configuration provides high availability by ensuring that each UPS system can independently support the load with an additional unit for redundancy. Given the 80 kW load, this setup implies that two separate N+1 systems are running, providing reliability and fault tolerance for the data center's power needs.
Detailed Explanation:
The N+1 notation denotes that each system has one additional unit beyond what is needed to carry the load, providing redundancy. With 2(N+1), there are two such setups, ensuring that if one fails, the other can still support the load without interruption, fulfilling high availability requirements.
EPI Data Center Specialist References:
EPI teaches that multiple redundant systems, such as 2(N+1), enhance data center reliability by ensuring that power is maintained even if a failure occurs in one system. This meets the stringent demands for uptime in critical environments.

NEW QUESTION # 30
Do you need to consider bullet (ballistics) protection when designing a data center?

A. Bullet (ballistics) protection is required by ANSI/TIA-942 for data centers Rated 3/4.
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 only required when the data center is located in an area with a high crime rate.

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 # 31
A new network storage device in a non-standard size rack of approximately 600 kg/1,300 lbs is going to be installed in the data center.
Are new floor loading calculations required?

A. Yes, additional floor loading calculations need to be done by the floor manager, which should be verified by the safety engineer.
B. Yes, a structural engineer, approved/endorsed by the building owner, should carry out new floor loading calculations.
C. No, as long as the equipment is less than 700 kg/1,500 lbs it will be within the limits.
D. No, specifications of equipment brought into the data center will already be known during the design of the data center, and therefore the floor will be able to handle it.

Answer: B

Explanation:
For heavy equipment, such as a network storage device weighing approximately 600 kg/1,300 lbs, new floor loading calculations are indeed required, particularly since the rack is non-standard. A structural engineer, approved by the building owner, should conduct these calculations to ensure the floor can safely support the new load without risking structural integrity.
Detailed Explanation:
Data centers are designed with specific floor load ratings, which are determined during the design phase based on anticipated equipment. When adding or replacing equipment that is significantly heavy or non-standard, reassessing the floor's capacity is essential to avoid overloading. A structural engineer has the expertise to verify if the existing floor can accommodate the weight and, if not, can recommend reinforcement measures.
This step ensures compliance with safety standards and helps prevent damage to the infrastructure, which could lead to costly repairs or even catastrophic failure in extreme cases.
EPI Data Center Specialist References:
EPI Data Center Specialist training advises that any changes in the data center load, particularly involving non-standard and heavy equipment, warrant a structural assessment. Ensuring compliance with floor load capacity is a critical safety and operational concern, as underscoring data center infrastructure reliability and safety is a priority in EPI's best practices.
