EXIN EPI Certified Data Centre Specialist Sample Questions (Q44-Q49):

NEW QUESTION # 44
What is a significant difference between a halocarbon gas-based fire suppression system and an inert gas-based fire suppression system?

  • A. Inert gas has smaller-sized gas containers than halocarbon gas.
  • B. Halocarbon gas works on the basis of heat removal and inert gas works on the basis of oxygen reduction.
  • C. Inert gas harms the environment and halocarbon gas does not.
  • D. Halocarbon gas works on the basis of oxygen reduction and inert gas works on the basis of heat removal.

Answer: B

Explanation:
A halocarbon gas-based fire suppression system primarily extinguishes fires through heat absorption. In contrast, an inert gas-based system works by reducing oxygen levels to a point where combustion cannot be sustained. Halocarbon agents, like FM-200, absorb heat from the fire, cooling it down, whereas inert gases, like nitrogen or argon, lower oxygen concentration.
Detailed Explanation:
Halocarbons are effective in quickly cooling flames and are suitable for electronic environments due to their fast action. Inert gases displace oxygen to suppress fires, making them ideal in occupied spaces where human safety can be managed during a fire event due to slower discharge times.
EPI Data Center Specialist References:
EPI training distinguishes between these suppression mechanisms, noting the importance of selecting the correct system based on specific needs like quick response versus oxygen displacement for environments with sensitive equipment.


NEW QUESTION # 45
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. 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.
  • C. Yes, a structural engineer, approved/endorsed by the building owner, should carry out new floor loading calculations.
  • D. No, as long as the equipment is less than 700 kg/1,500 lbs it will be within the limits.

Answer: C

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.


NEW QUESTION # 46
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. Airside economizer
  • B. Standard air conditioning units, as spares might not be readily available
  • 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: A

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 # 47
The data center has been in operation for about 1 year and 2 months. The dust levels in the computer room are relatively high.
What is the most likely root cause?

  • A. Every computer room has high dust levels due to constant high-speed air movement
  • B. Low pressure in the computer room
  • C. Floorboards are most likely not fitted correctly
  • D. The cleaning crew is not doing their work properly

Answer: C

Explanation:
High dust levels in a computer room are often due to improperly fitted floorboards. When floorboards are not securely installed or do not fit tightly, they allow dust and particles from the subfloor to enter the room. In a data center, this can lead to high levels of dust that affect air quality and equipment performance.
Detailed Explanation:
Raised floors in data centers can accumulate dust and debris, especially if the floorboards are not properly sealed. Loose or improperly fitted floorboards allow contaminants from the subfloor to enter the data center environment, increasing the dust levels over time. Proper installation and maintenance of floor panels are essential to prevent dust infiltration and maintain clean conditions.
EPI Data Center Specialist References:
EPI training emphasizes proper flooring installation and maintenance to control air quality within data centers. Correctly fitted floorboards prevent dust accumulation from the subfloor, which helps protect sensitive equipment and maintains a cleaner environment.


NEW QUESTION # 48
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. Star network design using coaxial cables
  • C. ToR (Top of Rack) design
  • 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.
