EXIN EPI Certified Data Centre Specialist 認定 CDCS 試験問題 (Q26-Q31):

質問 # 26
You are working with a customer who requires a guarantee that THDi levels coming from the UPS should not exceed more than 3% THDi. Furthermore, he wants to run a power-efficient data center. The UPS has a 6-Pulse SCR/Thyristor based rectifier. The current load on the UPS is approximately 80%. The customer indicates they are not expecting any changes on the ICT infrastructure for the next 3 years.
What should you recommend?

A. Nothing, the UPS will be able to take care of the right levels of THDi
B. Install an isolation transformer rated at K13 or K20
C. Install a passive harmonic filter on the UPS
D. Install an active harmonic filter on the UPS

正解：D

解説：
Given the customer's requirement to limit Total Harmonic Distortion (THDi) to below 3% and the presence of a 6-pulse SCR/Thyristor-based rectifier, an active harmonic filter is the best solution. A 6-pulse rectifier typically generates higher harmonic distortion, often exceeding 3%, especially under substantial loads like 80%. An active harmonic filter dynamically monitors and compensates for harmonic distortion, effectively reducing THDi and supporting a more power-efficient operation, aligning with the customer's energy efficiency goals.
Detailed Explanation:
Passive harmonic filters can reduce harmonics but are less effective at maintaining low THDi levels under varying loads. Active filters offer real-time correction and can achieve lower THDi levels than passive filters, especially in systems with fluctuating loads or where strict harmonic limits are required. Installing an active harmonic filter will ensure compliance with the specified THDi limits and optimize power quality.
EPI Data Center Specialist References:
EPI guidance on power quality management recommends active harmonic filters for environments where strict THDi levels are necessary. Active filters offer better control over harmonic levels, supporting both compliance and operational efficiency.

質問 # 27
What is the main reason to install Earth Leakage protection?

A. Protection against lightning strikes
B. Protection of human lives
C. Improvement of the data center grounding/earthing system
D. Protection of ICT equipment against high-frequency noise currents

正解：B

解説：
Earth Leakage Protection is primarily installed to protect human lives by detecting and disconnecting power when a fault current flows to the ground. This type of protection is essential to avoid electrical shock hazards that could occur when insulation fails, or equipment is improperly grounded.
Detailed Explanation:
Earth leakage currents can occur due to insulation faults or accidental contact with live parts. Earth Leakage Protection systems, such as Residual Current Devices (RCDs), quickly detect these faults and disconnect the circuit to prevent harm to personnel. This is especially crucial in environments like data centers where high-powered equipment is continuously running and any electrical fault can pose significant safety risks.
EPI Data Center Specialist References:
EPI emphasizes that human safety is paramount in data center operations. Proper grounding and leakage protection are fundamental safety measures, and EPI guidelines align with this focus, underscoring the importance of protecting personnel from electrical hazards through appropriate safety systems.

質問 # 28
What should you consider when using raised floor tiles with air deflectors or louvers?

A. Tiles with air deflectors or louvers can be very heavy.
B. Tiles with air deflectors or louvers will reduce the cooling capacity of the tile.
C. Tiles with air deflectors or louvers can only be used to cool storage equipment.
D. Tiles with air deflectors or louvers do not allow for a flexible cooling solution.

正解：A

解説：
Raised floor tiles with air deflectors or louvers are typically heavier than standard tiles due to the additional materials and mechanisms used to direct airflow. The added weight can pose challenges for installation and adjustment, and consideration must be given to the floor's load capacity and ease of maintenance.
Detailed Explanation:
Tiles with deflectors or louvers help direct airflow, enhancing cooling efficiency by focusing cool air where needed. However, these tiles are often heavier, which can affect handling and require reinforced raised floor systems. It's essential to factor in the weight for any floor tile replacements or installations to ensure they are compatible with the raised floor's structural capacity.
EPI Data Center Specialist References:
EPI data center design training mentions the potential impact of heavy tiles on floor handling and load capacity. Data center operators need to plan for safe handling and load-bearing capacity when using such specialized tiles.

質問 # 29
Smoke sensors need to be tested to ensure that they pick up a potential fire in the data center.
What should you recommend?

A. Press the self-test button on each sensor in the data center
B. Test the sensors by injecting smoke or simulated smoke directly into the sensor
C. Test the sensors according to the vendor specification
D. Inject smoke at the floor level

正解：C

解説：
Testing smoke sensors should be conducted according to the vendor specifications to ensure compliance with safety standards and accurate results. Vendors provide specific testing procedures to account for the sensor type, environment, and operational characteristics, ensuring that tests do not damage the equipment or provide false results.
Detailed Explanation:
Smoke sensors can vary by type and sensitivity, so following the vendor's recommended testing procedure ensures the sensors function correctly without risking sensor damage. Injecting smoke or using a self-test might be insufficient or could lead to inaccurate assessments if they do not align with the vendor's testing protocol.
EPI Data Center Specialist References:
EPI recommends adhering to manufacturer specifications for testing critical safety equipment, ensuring that tests reflect real-world conditions without compromising sensor integrity or reliability.

質問 # 30
The computer room has high levels of H2S gas contamination. What is the best option to resolve this issue?

A. Provide more air changes per hour by adding more fresh air to the computer room.
B. Clean the room and racks with a damp/wet cloth.
C. Vacuum the whole room using a HEPA/S-Class-based filter.
D. Install air-scrubbers.

正解：D

解説：
High levels of H2S (hydrogen sulfide) gas contamination in a computer room are best addressed by installing air-scrubbers. Air-scrubbers can effectively filter out contaminants, including corrosive gases like H2S, ensuring clean air circulation and protecting sensitive IT equipment from potential corrosion and damage.
Detailed Explanation:
Air-scrubbers are designed to remove various airborne contaminants and are particularly useful in environments where corrosive gases are present. These systems use filters or chemical reactions to neutralize harmful substances, making them ideal for data centers that need to maintain high air quality for equipment reliability.
EPI Data Center Specialist References:
EPI guidelines suggest air-scrubbing technologies to remove contaminants that pose risks to electronic equipment, maintaining air quality and reducing corrosion risk.
