Glycol cooled systems are advantageous because they are efficient and can service large data centers with multiple racks. Furthermore, glycol pipes can run long distances, allowing a single system to service several CRAC units. This eliminates the need for multiple systems, resulting in cost savings and reduced maintenance.
質問 # 19
For which one of these processes is Direct Current essential, and will not work with alternating current?
- A. Lighting
- B. Heating
- C. Electrolysis
- D. Turning a motor
正解：C
解説：
Explanation
Direct Current (DC) is essential for the process of electrolysis. Electrolysis is the process of breaking down a compound using an electric current. The electric current causes ions to move, which results in a chemical reaction that breaks down the compound. In order for electrolysis to work, a direct current is required, as the ions must flow in one direction. Alternating Current (AC) changes direction and would not provide a consistent flow of ions.
Heating, lighting, and turning a motor can be done by either DC or AC. Heating can be done by passing an electric current through a heating element, which can be powered by either DC or AC. Lighting can be done by passing an electric current through a light bulb, which can be powered by either DC or AC. A motor can be powered by either DC or AC, but the type of motor and the application will determine which type of current is more suitable.
質問 # 20

質問 # 21
Every air distribution system has a ____________ system and a _________ system
- A. Supply, Release
- B. Maintenance, Regulation
- C. Supply, Reverse
- D. Supply, Return
正解：D
解説：
Explanation
Every air distribution system has a supply system, which delivers conditioned air to the space, and a return system, which collects the air from the space and returns it to the air handling unit. The return system is responsible for providing the necessary negative pressure in the space to ensure proper air circulation.
質問 # 22
AC is more easily distributed than DC. This is because:
- A. AC can be transformed from a low voltage to a high voltage and back again with a transformer. DC cannot.
- B. AC can be transmitted using lighter wires.
- C. DC needs wires to be totally insulated, while AC wires can be bare, hung from insulator on pylons.
- D. Wires have less resistance if they are carrying AC
正解：A
解説：
Explanation
AC can be transformed from a low voltage to a high voltage and back again with a transformer, while DC cannot. This makes it easier to distribute AC electricity over long distances and is why it is used more widely than DC electricity. A and B are also true, as wires carrying AC can be bare and don't need to be totally insulated. Wires have less resistance when carrying AC electricity, which is why it is more efficient than DC.
質問 # 23
Which power distribution component is often used when many electrical devices are enclosed proximity especially with audio, video and computers?
- A. Backup server
- B. Server plug
- C. Power distribution units (PDU)
- D. Outlet strips
正解：C
解説：
Explanation
The best option for enclosing many electrical devices in proximity, especially with audio, video and computers, is Power Distribution Units (PDUs). PDUs are designed to provide power to multiple devices using a single power source, such as a wall outlet or a generator, while providing protection against power surges.
PDUs are generally equipped with multiple outlets to allow for a variety of electrical devices to be connected and powered simultaneously.
質問 # 24
Which mounted system can use any of the five heat removal methodologies?
- A. Chilled Mounted System
- B. Air Mounted System
- C. Floor Mounted System

質問 # 25
__________ represents the maximum power cable of being drawn by the equipment.
- A. VA rating
- B. Power rating
- C. Star rating
- D. Grade rating
正解：B
解説：
Explanation
Power rating represents the maximum power that can be drawn by the equipment. It is usually measured in watts (W) or kilowatts (kW) and represents the maximum amount of power that the equipment can consume without causing damage to the device or the power source.
VA rating (Volt-Ampere rating) is a measure of the apparent power in a circuit, which is the product of the voltage and current in the circuit. It is often used to describe the power handling capability of electronic devices and equipment.
Star rating is a rating system used to indicate the energy efficiency of electrical devices and equipment. The rating ranges from 1 to 5 stars, with 5 stars indicating the most energy-efficient device.
Grade rating is a rating system used to indicate the quality of electrical devices and equipment. It is used in different industry and can indicate the quality of electronic component and material used in equipment.
質問 # 26
Which one of the following is an advantage of using Natural Gas?
- A. Tends to cost more
- B. More exhaust able
- C. Minimum carbon build up
- D. Maximum carbon build up
正解：C
解説：
Explanation
The main advantage of using natural gas is that it tends to produce fewer carbon emissions than other fossil fuels, such as coal or oil. Natural gas combustion produces less carbon dioxide and other pollutants than other fuels, making it a cleaner and more renewable source of energy. Additionally, natural gas costs less than other fuels, making it a more cost-effective option.
質問 # 27
The distance that a signal's energy can travel in the time it takes for one cycle to occur is called the signal's:
- A. amplitude
- B. frequency
- C. period
- D. wavelength
正解：D
解説：
Explanation
Wavelength is a measure of the distance that a signal's energy can travel in the time it takes for one cycle of the signal to occur. It is calculated by dividing the speed of light by the frequency of the signal. Wavelength is generally expressed in meters (m).
質問 # 28
Which system in Air Distribution System takes the hot exhaust air from the IT equipment to the CRAC
- A. Maintenance system
- B. Supply system
- C. Regulation system
- D. Return system
正解：D
解説：
Explanation
The return system in an air distribution system takes the hot exhaust air from the IT equipment and returns it to the Computer Room Air Conditioner (CRAC) unit. The CRAC unit cools the hot exhaust air and recirculates it back into the data center. The return system typically includes ducts, grills, and other components that allow the hot air to be efficiently and effectively returned to the CRAC unit.
Supply system is responsible for bringing in the cooled and filtered air from the CRAC unit to the data center.
Maintenance system and regulation system are not related to air distribution system in the data center.
質問 # 29

質問 # 31
Which one of the following controls the voltage produced at the output of the alternator?
- A. Voltage Backup Device
- B. Voltage Meter
- C. Voltage Stabilizer
- D. Voltage Regulator
正解：D
解説：
Explanation
A voltage regulator controls the voltage produced at the output of the alternator. It's a device that maintains the output voltage of an alternating current (AC) power source within a safe range. The voltage regulator compares the actual output voltage to the desired voltage level and adjusts the voltage accordingly.
Voltage Meter, Voltage Stabilizer, and Voltage Backup Device are not devices that control the voltage produced at the output of the alternator. They are different types of equipment and have different functions.
A voltage meter is a device used to measure the voltage in an electrical circuit. A voltage stabilizer is an electronic device that maintains a constant voltage level. A voltage backup device is a device that provides temporary backup power in case of an electrical outage.
