質問 # 24
Which one of the following is an advantage of Air Cooled Self-Contained System?
- A. It doesn't requires ductwork and/or dropped ceiling
- B. It has more heat removal capacity per unit
- C. Lowest installation cost
- D. All components contain more than one unit
正解：A
解説：
Explanation
Air cooled self-contained systems are highly efficient and do not require ductwork and/or dropped ceiling for installation. This makes them a great choice for locations where installation costs are a major factor, such as in residential applications, or in places with limited space. Additionally, air cooled self-contained systems have more heat removal capacity per unit compared to water cooled systems, making them more cost-effective in the long run.

- C. 2
- D. 3
正解：A
質問 # 26
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. Wires have less resistance if they are carrying AC
- C. AC can be transmitted using lighter wires.
- D. DC needs wires to be totally insulated, while AC wires can be bare, hung from insulator on pylons.
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 # 27
Which one of the following is an advantage of Glycol Cooled System?
- A. No additional cost is required
- B. Can be used in big data centers
- C. Glycol pipes can run long distances and can service several CRAC units
- D. No maintenance of glycol
正解：C
解説：
Explanation
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 # 28
Which one of the following is an overall consideration for physical security?
- A. Identify the problem
- B. Apply the technology
- C. Define the problem
- D. Apply the solution
正解：C
解説：
Explanation
Defining the problem is an important overall consideration for physical security. This process involves identifying and analyzing the threats and vulnerabilities that could potentially affect the security of the system, as well as determining what steps need to be taken to mitigate these risks. This process should be done before any other steps are taken to ensure physical security, as it helps to ensure that the security measures are tailored to the specific needs of the system.
質問 # 29
Which one of the following is a Physical Security Device?
- A. Access Key
- B. Contactless smart card
- C. Token card
- D. Fiber optic cable
正解：B
解説：
Explanation
A contactless smart card is a physical security device that uses radio frequency identification (RFID) technology to identify and authenticate an individual. This type of card is used in a variety of applications, such as access control systems and digital payment systems. It is also used in physical access control systems, where the card is used to unlock doors or grant access to restricted areas. Contactless smart cards are also used in building access systems, where the card is used to grant access to certain areas of the building.
質問 # 30
A __________ generator system is a combination of an electrical generator and a mechanical engine mounted together to form a single piece of equipment.
- A. active
- B. passive
- C. standby
- D. software
正解：C
解説：
Explanation
A Standby Generator System is a combination of an electrical generator and a mechanical engine mounted together to form a single piece of equipment. The generator provides power to essential appliances and equipment in the event of a power outage. Standby Generator Systems are usually powered by gasoline, diesel, natural gas, or propane, and they are designed to be able to be activated quickly in the event of an emergency.
質問 # 31
Whenever electrical power is being consumed in an IT room or data center. __________ is generated.
- A. Humidity
- B. Heat
- C. Condensation
- D. Static electricity
正解：B
解説：
Explanation
Whenever electrical power is being consumed in an IT room or data center, heat is generated. This heat must be removed in order to maintain an optimal temperature for the equipment, and this is usually done through cooling systems such as air conditioning, air economization, liquid cooling, evaporative cooling, and immersion cooling.
質問 # 32
For which one of these processes is Direct Current essential, and will not work with alternating current?
- A. Turning a motor
- B. Lighting
- C. Heating
- D. Electrolysis
正解：D
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 # 33
Which one of the following measures the real power drawn by the load equipment?
- A. Amperes
- B. Volts
- C. Amps
- D. Watts
正解：D
解説：
Explanation
Watts measures the real power drawn by the load equipment and is determined by multiplying the volts and amps of the load
質問 # 34
Which type of power can be a source available to the data center that takes over the function of supplying when utility power is unavailable?
- A. Passive
- B. Alternate
- C. Active
- D. Standby
正解：D
解説：
Explanation
Standby power, also known as backup power, is a type of power that can be a source available to the data center that takes over the function of supplying when utility power is unavailable. Standby power systems are designed to provide power to critical loads in the event of a power outage, and can include generators, uninterruptible power supplies (UPS), and batteries. Standby power systems can be used to provide power to the data center for a short period of time, such as a few hours or days, until utility power is restored.
Passive, Active and Alternate are not specific type of power sources used in data center. They are terms used in different context and have different meaning.
質問 # 35

質問 # 36
If a waveform period is determined to be 10 microseconds in duration, what is the frequency of the signal?
- A. 100 kHz
- B. 100 Hz
- C. 10 kHz
- D. 1000 Hz
正解：A
解説：
Explanation
Frequency is the inverse of period, so to calculate the frequency of a signal with a period of 10 microseconds, you would divide 1 by the period, which is equal to 100 kHz.
質問 # 37
Which one of the following is a Physical Security Identification Method?
- A. Sound
- B. Batch ID
- C. Expression
- D. Voice

Voice identification is a physical security identification method that uses the sound of an individual's voice to identify them. This method is often used in combination with other identification methods, such as biometric scans, to provide a more secure form of authentication. Voice identification is used in a variety of situations, such as when accessing a secure facility or when making financial transactions.
