EXIN Certified Data Centre Professional (CDCP) 認定 CDCP 試験問題 (Q18-Q23):
質問 # 18
What should be considered when using a direct air handler for a data centre?
- A. The availability of three-phase power due to the high power requirements of these air handler units.
- B. Space available inside the computer rooms as the air handler space requirement for the inside the Computer room is quite large.
- C. Cost of operation as power consumption on these units tend to be higher compared to traditional air conditioning technology.
- D. Temperature, humidity and contamination of the outdoor environment.
正解:D
解説:
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.

質問 # 19
What is the most preferred unit of measure for cooling capacity?
- A. BTU
- B. Watt
- C. Ton
- D. Horsepower
正解:B
解説:
Cooling capacity is the measure of a cooling system's ability to remove heat from a space. The most preferred unit of measure for cooling capacity is watt (W), which is the SI unit for power. Watt is defined as the amount of energy transferred or converted per unit time. One watt is equal to one joule of energy per second. Using watt as the unit of measure for cooling capacity allows for easy comparison and calculation of the cooling performance and efficiency of different cooling systems.
Other units of measure for cooling capacity are ton, BTU, and horsepower, but they are less common and less convenient than watt. Ton is a unit of measure that describes how much water at freezing temperature can be frozen in 24 hours, equivalent to 3.5 kW or 12,000 BTU/h. BTU (British Thermal Unit) is a unit of measure that describes the amount of heat required to raise the temperature of one pound of water by one degree Fahrenheit, equivalent to 0.293 W. Horsepower is a unit of measure that describes the rate at which work is done, equivalent to 746 W.

質問 # 20
The three elements of the fire triangle are,and. (Choose three.)
- A. Oxygen
- B. Earth
- C. Water
- D. Fuel
- E. Heat
正解:A、D、E
解説:
The fire triangle is a simple model that illustrates the three elements that a fire needs to ignite and sustain:
oxygen, heat, and fuel. Oxygen is the oxidizing agent that enables the combustion reaction, heat is the energy source that raises the temperature of the fuel to its ignition point, and fuel is the material that reacts with oxygen and releases heat and light. Removing any one of these elements can extinguish a fire. For example, water can reduce the heat and the oxygen, sand or soil can smother the fuel and the oxygen, and fire extinguishers can displace the oxygen or lower the temperature.

質問 # 21
Which one of the following is the last stage in Stages of Combustion?
- A. Incipient
- B. Intense Heat
- C. Visible Smoke
- D. Flaming Fire
正解:D
解説:
The last stage in stages of combustion is flaming fire, which occurs when the fuel vapors and oxygen are mixed in the right proportion and ignited by a flame or a spark. Flaming fire is characterized by visible flames, intense heat, and rapid oxidation. Flaming fire can cause severe damage to the data center equipment, personnel, and business continuity. Therefore, it is important to prevent or suppress flaming fire as soon as possible using appropriate fire detection and suppression systems.

質問 # 22
Which source is used in fiber cable to transmit data?
- A. Pulse
- B. Light
- C. Electric
- D. Signals
正解:B
解説:
Fiber-optic cables use light as the source to transmit data. Light pulses are modulated to carry information through an optical fiber. The light is confined in the core of the fiber by total internal reflection at the core-cladding interface. The light travels along the fiber with minimal loss or interference, making it suitable for long-distance and high-bandwidth applications.
