最新的 EPI Data Centre CDCS 免費考試真題 (Q47-Q52):

問題 #47
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. 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.
B. Yes, additional floor loading calculations need to be done by the floor manager, which should be verified by the safety engineer.
C. No, as long as the equipment is less than 700 kg/1,500 lbs it will be within the limits.
D. Yes, a structural engineer, approved/endorsed by the building owner, should carry out new floor loading calculations.

答案：D

解題說明：
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.

問題 #48
You are working on the design of a new facility. The electrical riser of the building with high current power is located close to the area where sensitive IT equipment in the computer room will be located.
What should you recommend to reduce the amount of EMF coming from the electrical riser?

A. Install three-phase power cabling based on three individual core wires
B. Install bus bar trunking
C. Install single-phase power cabling
D. Install three-phase power cabling based on a combined cable (e.g. XLPE etc.)

答案：D

解題說明：
To reduce Electromagnetic Fields (EMF) emanating from the electrical riser near sensitive IT equipment, three-phase power cabling in a combined cable (such as XLPE) is effective. Combined cabling helps reduce EMF by keeping the conductors tightly packed, which minimizes magnetic fields generated by current flow. Cables like XLPE (cross-linked polyethylene) also offer better insulation, which helps mitigate EMF interference with nearby IT equipment.
Detailed Explanation:
Using a combined three-phase cable reduces EMF because the magnetic fields generated by each phase tend to cancel each other out when in close proximity. This arrangement helps reduce the overall magnetic field strength. In addition, XLPE and similar materials provide good insulation, making them a preferred choice for reducing EMF emissions around sensitive equipment.
EPI Data Center Specialist References:
EPI data center best practices recommend mitigating EMF interference through combined cabling arrangements, especially near areas where sensitive IT equipment is located. Reducing EMF is crucial to maintaining equipment reliability and ensuring compliance with safety standards.

問題 #49
You are allowed to use a calculator for this question. The total power consumption of the ICT equipment in a rack is 6 kW. The equipment is traditional ICT equipment with a Delta-T of approximately 11 °C / 20 °F. Calculate the approximate CFM required to cool the equipment in the rack.

A. Approximately 1,500 CFM
B. Approximately 1,000 CFM
C. Approximately 160 CFM
D. Approximately 500 CFM

答案：B

解題說明：
To calculate the cooling airflow requirement for ICT equipment, you can use the formula:
CFM=Power (kW)×3160ΔT(°F) ext{CFM} = rac{ ext{Power (kW)} imes 3160}{Delta T ( ext{°F})}CFM=ΔT(°F)Power (kW)×3160 For equipment consuming 6 kW with a Delta-T of 20°F:
CFM=6×316020=948≈1,000 CFM ext{CFM} = rac{6 imes 3160}{20} = 948 approx 1,000 , ext{CFM}CFM=206×3160=948≈1,000CFM Detailed Explanation:
This formula provides an estimate of the cubic feet per minute (CFM) of air required to cool the equipment based on its power consumption and the temperature difference (Delta-T) between intake and exhaust. The Delta-T represents the cooling effectiveness of the airflow.
EPI Data Center Specialist References:
EPI recommends using this calculation for determining airflow requirements in data centers, ensuring that cooling systems are adequately sized to maintain equipment within safe temperature limits.

問題 #50
What indicates the breaking capacity of a fuse or breaker?

A. The maximum voltage, in case of an electrical surge, that the fuse or breaker can handle without being destroyed or causing an electric damaging arc.
B. The current that a fuse or breaker is able to interrupt without being destroyed or causing an electric damaging arc.
C. The current at which the device will trip.
D. Mechanical strength of the casing of a fuse or breaker.

答案：B

解題說明：
The breaking capacity of a fuse or breaker indicates the maximum current it can safely interrupt without being damaged or creating a dangerous arc. This value is crucial for ensuring that the device can handle fault conditions and prevent equipment damage or fire risks due to excessive current flow.
Detailed Explanation:
The breaking capacity, also known as the interrupting rating, ensures that the fuse or breaker can safely handle fault currents up to a specified limit. Exceeding this capacity could result in the device failing to interrupt the current, potentially causing hazardous conditions like electrical arcs.
EPI Data Center Specialist References:
EPI training underscores the importance of matching fuses and breakers with appropriate breaking capacities for the anticipated fault levels in data centers to ensure reliable and safe operation.

問題 #51
When shielding material reaches its saturation point, what will be the impact?

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

答案：D

解題說明：
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.

問題 #52
