EXIN EPI Certified Data Centre Specialist Sample Questions (Q18-Q23):

NEW QUESTION # 18
What is the focus of the Open Compute Project (OCP)?

Answer: A

Explanation:
The Open Compute Project (OCP), initiated by Facebook in 2011, focuses on open designs for servers, storage, racks, and power systems. The goals are:
* Reduce energy consumption by using efficient hardware.
* Save materials by eliminating unnecessary components.
* Lower costs by standardizing and sharing open designs.
Option B is wrong-OCP hardware can be adopted by enterprises as well. Option C is unrelated (OCP is hardware, not OS). Option D is broader cloud adoption, not OCP's direct mission.
Thus, the primary focus is energy, material, and cost savings through open-source hardware.
References: OCP Foundation Mission Statement, ANSI/TIA-942-B Annex (Emerging Technologies).


NEW QUESTION # 19
You want to manage temperature and humidity only at the facility level in your data center. All servers use front-to-rear airflow. Which location for measurement should you recommend?

Answer: C

Explanation:
ASHRAE recommends temperature and humidity be measured in the cold aisle, in front of racks, at approximately 1.5 m above the floor (average human working height) and 0.3-0.5 m from the rack face. This location captures the environmental conditions experienced at the IT equipment air intake, while still representing facility-level conditions (not single device-level).
* Option A and C (at 50 mm intake/rear) are too close to individual servers and suited only for rack-level monitoring, not facility monitoring.
* Option D (rear measurement) reflects exhaust air, not intake, and thus cannot be used to control environmental setpoints.
Maintaining measurement at standardized facility locations allows comparisons against ASHRAE's recommended and allowable ranges (18-27 °C for Class A1 environments, 40-60% RH).
References: ASHRAE TC 9.9 "Thermal Guidelines for Data Processing Environments" (2016), ANSI/TIA-
942-B §6.5.


NEW QUESTION # 20
A 5kW (power consumption) server keeps crashing with the message 'temperature too high'.
The intake temperature is measured at 25 °C/77 °F and a relative humidity (RH) level of 50%.
The exhaust temperature is 29 °C/84 °F and 45% RH.
The raised floor is providing an adequate amount of CFM/CMH at a reasonable velocity.
The pressure under the raised floor is approximately 25 Pa/0.1 inch H₂O.
Analyze the situation and indicate what the most likely cause is for this server to crash.

Answer: C

Explanation:
The server's repeated overheating despite adequate intake and exhaust temperatures suggests that dust buildup inside the server may be impeding heat transfer. Dust accumulation can obstruct airflow within the server, insulate components, and disrupt the convection-based cooling systems that regulate internal temperatures, leading to overheating and potential hardware failures.
Detailed Explanation:
While the intake and exhaust temperatures appear within acceptable ranges, internal dust can reduce airflow and impede cooling efficiency, causing internal components to overheat despite seemingly normal ambient conditions. Regular cleaning and maintenance are critical for preventing dust-related issues, especially in high-powered equipment like a 5kW server.
EPI Data Center Specialist References:
EPI emphasizes regular maintenance to prevent dust buildup in data center equipment. Dust can significantly impact cooling efficiency and lead to overheating, which underlines the importance of routine cleaning for optimal server performance.


NEW QUESTION # 21
What is the advantage or disadvantage of using MPO (Multi-fiber Push On)/pre-terminated fiber?

Answer: A

Explanation:
MPO (Multi-fiber Push On) pre-terminated fiber offers the advantage of quick installation and supports high- speed upgrades up to 40 Gbit/s and 100 Gbit/s. This technology simplifies connections by allowing multiple fibers to be connected in a single plug-and-play module, reducing installation time and making future expansions or upgrades to higher speeds easier.
Detailed Explanation:
MPO connectors consolidate multiple fiber connections into a single interface, which simplifies cable management and reduces installation complexity. This setup is particularly beneficial in data centers where high-speed networks are essential, and where rapid deployment is necessary. MPO pre-terminated fiber also supports the use of OM4 fiber, making it compatible with existing high-performance cabling infrastructure.
EPI Data Center Specialist References:
EPI training highlights that pre-terminated fiber solutions, like MPO, can greatly enhance efficiency in data centers. By reducing installation time and providing scalability for higher transmission speeds, they align with best practices for maintaining flexible and future-ready network infrastructure.


NEW QUESTION # 22
Smoke sensors must be installed in the computer room. What is the minimum density?

Answer: C

Explanation:
NFPA 75 (Standard for IT Equipment Protection) and NFPA 72 (Fire Alarm Code) recommend installing at least one smoke detector per 250 ft² (#25 m²) in IT rooms. This ensures early detection in high-value environments.
* A and B are far too dense, exceeding NFPA minimums.
* D is too sparse and would not meet early detection requirements.
Therefore, the correct standard density is 1 per 25 m².
References: NFPA 75 §5.4.3, NFPA 72 Table 17.6.3.5.1.
