EXIN EPI Certified Data Centre Specialist Sample Questions (Q102-Q107):

NEW QUESTION # 102
In which stage of the data center life cycle does testing and commissioning take place?

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

Answer: B

Explanation:
The data center life cycle is typically divided into four stages:
* Design (scope, architecture, planning)
* Implement (construction, installation, testing & commissioning)
* Operate/Optimize (day-to-day operations, maintenance, continuous improvement)
* Retire (decommissioning and migration)
Testing and commissioning occur in the Implement stage, after construction but before handover. This includes Integrated Systems Testing (IST), which validates that all systems (electrical, cooling, fire protection, telecom) perform to design intent and redundancy requirements.
Without commissioning, the data center cannot be certified or considered operational.
References: Uptime Institute Commissioning Guidelines, ANSI/TIA-942-B Annex F (Lifecycle), ISO/IEC
30182.

NEW QUESTION # 103
A data center requires an audit to find out whether it conforms with ANSI/TIA-942 Rated-3 (concurrently maintainable).
Will the network architecture be part of this audit?

A. No, as concurrently maintainable only applies to electrical and mechanical (power and cooling).
B. No, only the type of cabling used will be audited.
C. Yes, amongst other aspects, the network architecture should be Rated-3 compliant with the requirements of ANSI/TIA-942.
D. Yes, but only if the network administration does not comply with ANSI/TIA-606.

Answer: C

Explanation:
For a Rated-3 data center, network architecture is indeed a key component of the audit under ANSI/TIA-942.
This rating requires concurrent maintainability across all systems, including telecommunications infrastructure. The network architecture must therefore meet specific redundancy and reliability standards to ensure uninterrupted operations during maintenance or failure of any single component.
Detailed Explanation:
Rated-3 requirements extend beyond electrical and mechanical systems to include network architecture. This ensures that telecommunications systems are also designed for concurrent maintainability, thus contributing to overall uptime and resilience.
EPI Data Center Specialist References:
EPI endorses comprehensive assessments for Rated-3 facilities, emphasizing that network systems must meet standards for redundancy and concurrent maintainability, which align with ANSI/TIA-942's holistic approach to data center reliability.

NEW QUESTION # 104
The location of a data center is just above the Arctic Circle (North Pole). The outside air temperature is never above 21°C/70°F.
Taking energy efficiency as the highest priority, which cooling system should you recommend?

A. Standard air conditioning units, as spares might not be readily available
B. Airside economizer
C. Any cooling system can be efficient because the outside air temperature will not influence the temperature of the air intake of the ICT equipment
D. Waterside economizer

Answer: B

Explanation:
In locations with consistently cold temperatures, such as above the Arctic Circle, an airside economizer is the most energy-efficient cooling solution. Airside economizers use cool outside air to lower indoor temperatures, reducing or even eliminating the need for mechanical cooling. Given the consistently low temperatures, this method maximizes energy efficiency by leveraging natural cooling.
Detailed Explanation:
Airside economizers are ideal in environments where outside temperatures are consistently low. By drawing in and filtering cold outdoor air, they directly cool the indoor environment, thereby reducing energy consumption significantly compared to traditional air conditioning. This cooling approach aligns with energy efficiency goals by minimizing mechanical cooling demands.
EPI Data Center Specialist References:
EPI recommends the use of airside economizers in cold climates to achieve high energy efficiency, as they allow data centers to capitalize on ambient conditions for cooling, aligning with sustainability and cost-saving practices.

NEW QUESTION # 105
Maximum exposed area of fire-rated glass is 2 m², but the window is 5 m². What is the best option?

A. Split into two equal parts with aluminum frame
B. Split into two equal parts with silicone
C. Split into smaller parts within 2 m² using fire-rated frames
D. Replace with normal glass

Answer: C

Explanation:
Fire-rated glass must be installed within manufacturer's tested maximum exposed area. Oversized panes risk failure under fire conditions. If the window exceeds 2 m², the correct approach is to subdivide it into smaller sections, each #2 m², using approved fire-rated frames.
Options B and C (silicone or aluminum splits) are not certified fire-rated framing methods. Option A is unsafe because normal glass provides no fire protection.
Therefore, option D ensures compliance and safety.
References: EN 1363-1 (Fire Resistance Tests), NFPA 80 (Fire Doors & Windows).

NEW QUESTION # 106
A data center scores Rated-3 in mechanical, Rated-4 in electrical, and Rated-2 in architectural.
What is the overall Rating of this data center when the Rating is based on the ANSI/TIA-942?

A. Depends on the Rating scored in telecommunications
B. Rated-4 since that is the highest rating received
C. Rated-4 since electrical is more important than mechanical and architectural
D. Rated-2 since that is the lowest rating received

Answer: D

Explanation:
According to ANSI/TIA-942 standards, the overall data center rating is determined by the lowest rating among all evaluated categories. Therefore, if a data center is rated 2 in architectural, despite being rated higher in mechanical and electrical, the overall rating is Rated-2. This approach ensures that all aspects meet a minimum standard and prevents a higher rating if any critical area does not comply.
Detailed Explanation:
ANSI/TIA-942 evaluates data centers across several areas, including mechanical, electrical, architectural, and telecommunications. The overall rating reflects the lowest rated category, ensuring that no aspect of the data center's design or operation falls below the specified level. Thus, in this case, the architectural rating of 2 dictates the final rating, ensuring a comprehensive and balanced assessment of reliability and resilience across all aspects.
EPI Data Center Specialist References:
EPI Data Center Specialist training aligns with ANSI/TIA-942, stating that the final rating must reflect the lowest score to ensure comprehensive reliability across all critical infrastructure categories. This avoids overstating the data center's resilience and ensures uniform standards across areas.
