최신 EPI Data Centre CDCS 무료샘플문제 (Q38-Q43):

질문 # 38
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 front/intake of the server at 50 mm/2 inch
B. At the back/rear 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

정답：A

설명：
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.

질문 # 39
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 pre-action system.
C. Replace the wet pipe system with a dry pipe system.
D. Replace the wet pipe system with a deluge system.

정답：B

설명：
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.

질문 # 40
In order to save energy, you are going to install an automated system to switch off lights. What should be taken into consideration when installing such a system?

A. The system should not be based on motion detection as the lights might suddenly switch off while staff is still at work.
B. Security guards should perform regular inspections verifying the system works.
C. At all times, the levels should allow for security cameras to function properly.
D. It is not advisable to use such a system since it will reduce the lifetime of LED lighting.

정답：C

질문 # 41
The air intake of the mission-critical server at the top of the rack is measuring 25 °C/77 °F.
Is this acceptable?

A. As long as it does not exceed the average server room temperature of 38 °C/100 °F
B. Depends on the ANSI/TIA-942 Rating the data center needs to comply with
C. Yes, this is allowed according to the standards and guidelines
D. No, the temperature needs to be 20 °C/68 °F

정답：C

설명：
An air intake temperature of 25 °C (77 °F) at the top of the rack is acceptable according to data center standards and guidelines, such as those from ASHRAE. This temperature falls within the recommended range for inlet temperatures, which is typically between 18°C (64°F) and 27°C (81°F).
Detailed Explanation:
ASHRAE standards provide guidelines on acceptable temperature ranges for air intake in data centers to balance cooling efficiency and equipment safety. A temperature of 25°C is within the recommended operational range, allowing data centers to optimize energy efficiency while maintaining safe conditions for IT equipment.
EPI Data Center Specialist References:
EPI guidelines align with ASHRAE recommendations for server intake temperatures, confirming that 25°C is within acceptable limits for most mission-critical equipment. This ensures the data center maintains an efficient and reliable environment.

질문 # 42
Is it allowed to make design changes during the implementation phase?

A. Only when there is a strong business and/or technical justification.
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. No, after a design freeze no further changes are allowed.

정답：A

설명：
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.
