EXIN EPI Certified Data Centre Specialist 認定 CDCS 試験問題 (Q29-Q34):

質問 # 29
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. Floorboards are most likely not fitted correctly
B. The cleaning crew is not doing their work properly
C. Low pressure in the computer room
D. Every computer room has high dust levels due to constant high-speed air movement

正解：A

解説：
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.

質問 # 30
The noise levels in the data center are approximately 91 dB (A).
Do employers need to take precautions?

A. No, anything less than 100 dB (A) is acceptable.
B. As long as the data is compliant to ISO/IEC 27001 it is acceptable.
C. There are no regulations regarding noise levels inside a building. Regulations only apply to noise pollution outside of the building.
D. Yes, since it is mandated by regulations.

正解：D

解説：
In a data center with noise levels of 91 dB (A), employers are indeed required to take precautions to protect personnel, as this level exceeds commonly accepted safety thresholds for occupational noise exposure. Regulations, such as those from the Occupational Safety and Health Administration (OSHA) or similar agencies, mandate specific controls and protections for environments with high noise levels.
Detailed Explanation:
Noise levels above 85 dB (A) typically trigger requirements for hearing conservation programs. At 91 dB (A), steps like providing ear protection, conducting regular noise assessments, and possibly implementing engineering controls to reduce noise should be taken. Extended exposure to such levels can lead to hearing loss, so regulatory compliance ensures both immediate and long-term protection for personnel.
EPI Data Center Specialist References:
EPI guidelines for data center safety address noise exposure as part of the environmental safety measures. EPI recommends adhering to local occupational health regulations, as excessive noise can harm personnel and affect operational efficiency due to potential health hazards.

質問 # 31
What is the calculation for the desired attenuation factor for shielding material?

A. A = M / R
Where A is Attenuation M is the maximum acceptable value R is the real value measured
B. You do not have to calculate the attenuation factor for shielding material as it always has the same attenuation
C. A = 20 log (M / R)
Where A is Attenuation M is the maximum acceptable value R is the real value measured
D. A = 20 log (R / M)
Where A is Attenuation R is the real value measured M is the maximum acceptable value

正解：D

解説：
The attenuation factor for shielding material is typically calculated using the formula A = 20 log (R / M). This equation provides the attenuation in decibels (dB), where R represents the measured electromagnetic field strength, and M is the maximum acceptable level. The logarithmic scale helps quantify how much the shielding reduces EMF levels relative to the maximum allowable value.
Detailed Explanation:
This formula calculates attenuation by comparing the measured value with the acceptable threshold, with the result expressed in decibels. A higher attenuation indicates more effective shielding material, essential for environments requiring robust EMF management.
EPI Data Center Specialist References:
EPI standards include the use of logarithmic formulas to evaluate attenuation levels, ensuring that shielding materials provide adequate reduction in EMF to protect sensitive equipment within data centers.

質問 # 32
What should be considered when installing overhead data cabling?

A. Optical fiber cabling should always be positioned on top of the copper cabling in the same cable tray to avoid damage to the sensitive optical fiber.
B. To maintain minimum separation from power and ensure that the fire detection and suppression systems are not hindered.
C. Copper data cabling should not be placed in metal cable trays.
D. All cabling should make sharp bends directly into the rack to avoid usage of additional space and blocking the airflow on top of the rack.

正解：B

解説：
When installing overhead data cabling, it's crucial to maintain minimum separation from power cables to prevent electromagnetic interference. Additionally, cabling should be arranged so that it does not obstruct fire detection and suppression systems, allowing for proper sensor function and suppression agent dispersion in the event of a fire.
Detailed Explanation:
Separation between power and data cabling minimizes the risk of interference and helps ensure compliance with standards for signal integrity. Proper placement relative to fire suppression systems ensures that any smoke or heat can be effectively detected, and suppression agents can be evenly distributed without obstruction from cabling.
EPI Data Center Specialist References:
EPI guidelines emphasize maintaining adequate separation between power and data cables for safety and performance and ensuring cabling does not interfere with essential safety systems in data centers.

質問 # 33
Is it allowed to make design changes during the implementation phase?

A. No, after a design freeze no further changes are allowed.
B. Yes, but only when time to implement is not exceeded.
C. Any change is fine as long as it is within the scope of the project.
D. Only when there is a strong business and/or technical justification.

正解：D

解説：
Design changes during the implementation phase are generally allowed only when there is a strong business and/or technical justification. Changes at this stage can lead to delays, increased costs, or compromise design integrity. Thus, a rigorous assessment is required to ensure any modifications are essential and provide clear benefits or address critical issues.
Detailed Explanation:
Changes post-design freeze should be minimized to avoid scope creep and additional costs. However, if a technical issue arises that would affect operational goals, or a business need warrants modification, justified changes are permissible, following an impact assessment and approval process.
EPI Data Center Specialist References:
EPI project management guidelines recommend a controlled change management process during implementation, allowing changes only when they align with critical objectives or address unforeseen issues that affect the project's success.
