최신 EPI Data Centre CDCP 무료샘플문제 (Q48-Q53):

질문 # 48
What should be considered when using a direct air handler for a data centre?

A. Cost of operation as power consumption on these units tend to be higher compared to traditional air conditioning technology.
B. The availability of three-phase power due to the high power requirements of these air handler units.
C. Space available inside the computer rooms as the air handler space requirement for the inside the Computer room is quite large.
D. Temperature, humidity and contamination of the outdoor environment.

정답：D

설명：
Direct air handlers are a type of cooling system that use outdoor air to cool the data centre. They draw in fresh air from outside, filter it, and supply it to the data centre at the desired temperature and humidity level. Direct air handlers can reduce the energy consumption and operating costs of data centres by eliminating the need for mechanical cooling or refrigeration. However, they also have some challenges and limitations that need to be considered. One of the main factors to consider when using direct air handlers for data centres is the temperature, humidity and contamination of the outdoor environment. Depending on the location and climate of the data centre, the outdoor air may not always be suitable for cooling the data centre. For example, if the outdoor air is too hot, too humid, or too polluted, it may not provide enough cooling capacity, or it may damage the IT equipment or cause corrosion. Therefore, direct air handlers need to have sensors and controls to monitor the outdoor air quality and adjust the airflow accordingly. They may also need to have backup cooling systems or supplementary cooling devices, such as evaporative coolers or heat exchangers, to cope with extreme weather conditions or peak loads.

질문 # 49
What is the current recommended temperature for ICT equipment as described in the ASHREA TC 9.9 guideline?

A. 20-40 °C (68 - 104 °F)
B. 8-18 C (46.4 -64.4 °F)
C. 25-45 °C (77 - 113 °F)
D. 18-27 C (64.4 - 80.6°F)

정답：D

설명：
The current recommended temperature for ICT equipment as described in the ASHRAE TC 9.9 guideline is
18-27 C (64.4 - 80.6°F). This is the recommended range for the dry-bulb temperature at the inlet of the servers, which is the most critical parameter for ensuring the optimal performance and reliability of the ICT equipment. The recommended range is based on the thermal specifications of the majority of the ICT equipment in the market, as well as the energy efficiency and environmental considerations of the data centre cooling systems. The recommended range is suitable for Classes A1 to A4 of the ASHRAE thermal guideline classes, which cover different types and generations of ICT equipment.

질문 # 50
What is the effect of a high relative humidity in the data centre?

A. There is a risk of corrosion.
B. There is a risk of electrostatic discharge.
C. In a data centre environment relative humidity is not important, only temperature matters.
D. There is a risk of not properly functioning of the smoke detectors.

정답：A

설명：
High relative humidity in a data center can lead to corrosion of metal parts and electronic contacts, potentially causing failures. Electrostatic discharge is a risk with low humidity, not high.

질문 # 51
Which type of Humidifier suspends quartz lamps over an open pool of water?

A. Ultrasonic Humidifier
B. Water Canister Humidifier
C. Infrared Humidifiers
D. Steam Canister Humidifier

정답：C

설명：
Infrared humidifiers are a type of humidifier that use quartz lamps to heat water in an open pool and evaporate it into the air. They are energy-intensive and require frequent maintenance and cleaning. They are not recommended for data centers, as they can introduce contaminants and bacteria into the air, and increase the risk of fire and electrical hazards.

질문 # 52
The UPS vendor is offering the latest model of their UPS to you. The vendor indicates that the UPS is categorized as VFD class.
Is this UPS a fit for your mission-critical data centre?

A. Yes, but only if they install it with a 12-pulse rectifier.
B. Yes
C. No
D. Yes, but only if you oversize the battery bank with 10%.

정답：C

설명：
A UPS (uninterruptible power supply) that is categorized as VFD class is not a fit for your mission-critical data centre, because it does not provide adequate protection against voltage and frequency variations. VFD stands for Voltage and Frequency Dependent, which means that the output voltage and frequency of the UPS depend on the input voltage and frequency. VFD UPSs are also known as offline, standby, or line-interactive UPSs. They typically switch to battery power only when the input power fails or goes beyond a certain threshold. However, this switching may cause a brief interruption or a transient in the output power, which can affect the performance and reliability of the ICT equipment. Moreover, VFD UPSs do not filter or regulate the input power, which means that they pass on any voltage or frequency fluctuations, harmonics, or noise to the output power. These power quality issues can also damage or degrade the ICT equipment and the data.
For your mission-critical data centre, you need a UPS that is categorized as VFI class, which stands for Voltage and Frequency Independent. VFI UPSs are also known as online, continuous, or double-conversion UPSs. They provide a constant and clean output power that is independent of the input power. VFI UPSs convert the input AC power to DC power, and then convert it back to AC power with the desired voltage and frequency. This double conversion process isolates the output power from the input power, and eliminates any power quality issues. VFI UPSs also have zero switching time, which means that they do not cause any interruption or transient in the output power when switching to battery power. VFI UPSs are designed to protect the ICT equipment and the data from any adverse effects of voltage and frequency variations, and to ensure the highest level of availability and reliability.
