EXIN EPI Certified Data Centre Specialist Sample Questions (Q23-Q28):

NEW QUESTION # 23
Management has requested a 15-minute battery bank assuming full load on the UPS. The UPS vendor has provided the following specifications of the UPS:
* Rated power: 30 kVA
* Rectifier input voltage: 400 V/3 phase
* Rectifier input power factor: 0.8
* Battery rated voltage: 384 V
* Number of cells: 192
* End of discharge voltage: 308 V
* Inverter output voltage: 400 V/3 phase
* Inverter output power factor: 0.8
What information is missing to perform the battery calculation?

  • A. UPS efficiency
  • B. Load imbalance on the phases
  • C. Inverter efficiency
  • D. Available battery charging current

Answer: A

Explanation:
To determine the required capacity of the battery bank for the 15-minute runtime at full load, one must know the total power requirement that the battery bank must supply. The specifications provided include most of the necessary details, such as rated power, input voltage, battery voltage, and discharge voltage. However, one critical piece of information is missing: the UPS efficiency.
Detailed Explanation:
In a data center UPS system, the battery bank is designed to supply power for a set duration when there is an input power failure. The UPS efficiency affects the actual power the UPS can deliver to the load compared to the power it draws from the batteries. The efficiency factor is necessary to accurately calculate the required capacity of the battery bank since it determines how much input power is needed from the batteries to supply the load at full capacity. The formula typically used to determine battery capacity involves factoring in UPS efficiency, as it allows you to understand the losses within the UPS system.
If UPS efficiency is not considered, there would be an inaccurate estimation of the actual power needed from the batteries. For instance, if a UPS has 90% efficiency, only 90% of the power drawn from the batteries reaches the load. Without knowing this efficiency, it is not possible to calculate the battery bank size accurately, as you cannot accurately estimate the losses within the UPS itself.
EPI Data Center Specialist References:
According to EPI Data Center Specialist training, understanding the UPS efficiency is essential for battery sizing. Without it, the calculations could lead to either undersizing or oversizing the battery bank, which affects both reliability and cost-effectiveness of the UPS system. The EPI Data Center Specialist course emphasizes that battery sizing must account for all losses within the UPS system, with efficiency being a primary factor in these calculations.


NEW QUESTION # 24
When shielding material reaches its saturation point, what will be the impact?

  • A. The shielding material will reach its maximum electrically charged state.
  • B. The shielding material will increase its permeability factor.
  • C. The shielding material will no longer be able to attenuate (reduce) additional EMF.
  • D. The shielding material will reach its optimal shielding performance state.

Answer: C

Explanation:
When shielding material reaches its saturation point, it can no longer effectively attenuate additional EMF. At saturation, the material's ability to absorb or redirect magnetic fields is exhausted, meaning it cannot provide further shielding beyond this point. Additional EMF exposure would pass through the material without significant reduction.
Detailed Explanation:
Saturation occurs when the material's magnetic domains are fully aligned with the magnetic field, leaving no capacity to absorb or deflect further EMF. This can happen with high EMF levels, beyond the material's design limits, resulting in a breakdown of shielding effectiveness.
EPI Data Center Specialist References:
EPI guidelines on EMF management indicate that selecting appropriate shielding materials with sufficient capacity is essential to prevent saturation and ensure continuous protection. Saturation limits should be considered during design to avoid compromised shielding performance.


NEW QUESTION # 25
You need to determine the strategy for the cooling audit. All the servers are based on a front-to-rear (F-R) airflow design.
Which location for the temperature/humidity measurement should you recommend for the audit?

  • A. At the back/rear of the server at 50 mm/2 inch
  • B. At the front/intake of the server at 50 mm/2 inch
  • C. At 1.5 meters/5 feet above the floor in the middle of the cold aisle
  • D. At 1.5 meters/5 feet above the floor in the middle of the hot aisle

Answer: B

Explanation:
For a cooling audit in a data center, it is essential to measure temperature and humidity where air enters the servers to accurately assess cooling performance. In this case, since all servers have a front-to-rear (F-R) airflow design, measuring at the front/intake of the server will provide a precise understanding of the cooling conditions that the equipment is experiencing.
Detailed Explanation:
Servers with a front-to-rear airflow design draw in cool air from the cold aisle at the front, which is then exhausted into the hot aisle at the rear. By measuring temperature and humidity 50 mm/2 inches from the front intake, you gather data on the air conditions right before it enters the servers, providing an accurate representation of the cooling environment as it directly impacts the equipment.
Measuring in the cold aisle at the front intake ensures that the readings reflect the actual conditions of the incoming air that the servers depend on for effective cooling. This approach is consistent with best practices for maintaining thermal conditions in a data center, as it helps confirm that the cooling systems are delivering air within the required temperature and humidity specifications.
EPI Data Center Specialist References:
According to the EPI Data Center Specialist curriculum, the optimal placement for temperature and humidity sensors is at the intake of the equipment in the cold aisle, as it directly correlates to the environmental conditions affecting the servers. This positioning allows for a more effective audit of cooling performance, which is critical for maintaining the reliability and efficiency of the data center's operations.


NEW QUESTION # 26
When designing a data center network, your company wants to minimize the number of network switches to manage.
What type of physical cabling layout would be the best choice?

  • A. EoR (End of Row) design
  • B. ToR (Top of Rack) design
  • C. Star network design using coaxial cables
  • D. It does not matter as the number of switches is not influenced by the physical cabling layout

Answer: A

Explanation:
An End of Row (EoR) design minimizes the number of network switches, as multiple racks can share a single switch at the end of a row, reducing switch counts and simplifying management. This design centralizes network switching to fewer points, which reduces the complexity and number of switches required compared to a Top of Rack (ToR) design, where each rack typically has its own switch.
Detailed Explanation:
In EoR designs, each row has a single network switch that handles the connections for all racks within that row. This reduces the number of individual switches needed and centralizes network management, which is ideal for minimizing equipment and simplifying infrastructure in the data center.
EPI Data Center Specialist References:
EPI promotes the EoR design as a way to reduce switch counts and streamline management in data centers. This configuration allows for easier scaling and maintenance while maintaining efficient network connectivity.


NEW QUESTION # 27
The building in which the computer room is housed is required to have a sprinkler system. The building is therefore equipped with a wet pipe system.
What action, if any, should you recommend for the computer room?

  • A. Maintain the current wet pipe system.
  • B. Replace the wet pipe system with a deluge system.
  • C. Replace the wet pipe system with a dry pipe system.
  • D. Replace the wet pipe system with a pre-action system.

Answer: D

Explanation:
In computer rooms, replacing a wet pipe system with a pre-action system is advisable. Pre-action systems provide additional protection by requiring two triggers (e.g., heat and smoke) before water is released, minimizing the risk of accidental discharge and water damage, which is crucial for safeguarding sensitive IT equipment.
Detailed Explanation:
Wet pipe systems contain water in the pipes at all times, which poses a higher risk of accidental discharge. Pre-action systems, however, only fill the pipes with water upon detection of a fire, reducing the risk of water-related damage due to leaks or malfunctions. This approach is considered best practice for environments housing sensitive electronic equipment.
EPI Data Center Specialist References:
EPI advises using pre-action fire suppression in data centers to reduce risks associated with accidental water release, providing a safer and more controlled fire response that better protects critical infrastructure.
