NEW QUESTION # 24
AC is more easily distributed than DC. This is because:
- A. AC can be transmitted using lighter wires.
- B. AC can be transformed from a low voltage to a high voltage and back again with a transformer. DC cannot.
- 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
Answer: B
Explanation:
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.
NEW QUESTION # 25
Which one of the following is an overall consideration for physical security?
- A. Identify the problem
- B. Apply the solution
- C. Apply the technology
- D. Define the problem
Answer: D
Explanation:
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.

NEW QUESTION # 28
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. Standby
- B. Active
- C. Alternate
- D. Passive
Answer: A
Explanation:
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.
NEW QUESTION # 29
For which one of these processes is Direct Current essential, and will not work with alternating current?
- A. Turning a motor
- B. Heating
- C. Electrolysis
- D. Lighting
Answer: C
Explanation:
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.
NEW QUESTION # 30
True or False: Fuel availability generally dictates the type of standby generator selected
- A. False
- B. True
Answer: B
Explanation:
Explanation
Fuel availability generally dictates the type of standby generator selected as different types of generators use different types of fuel. For example, gasoline generators are typically used in residential or small commercial applications, while diesel generators are usually used in larger industrial and commercial applications. Propane or natural gas generators may also be used, depending on the availability of fuel sources.
NEW QUESTION # 31
Which power distribution component is often used when many electrical devices are enclosed proximity especially with audio, video and computers?
- A. Outlet strips
- B. Power distribution units (PDU)
- C. Server plug
- D. Backup server
Answer: B
Explanation:
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.
NEW QUESTION # 32
___________ protects electrical equipment from damage caused by overload or short circuit.
- A. IEC cable
- B. Server
- C. Volt switch
- D. Circuit breaker
Answer: D
Explanation:
Explanation
A circuit breaker is a device that protects electrical equipment from damage caused by overload or short circuit. It does this by automatically disconnecting the power supply when it detects a surge or drop in voltage, preventing the equipment from being damaged.
NEW QUESTION # 33
If a waveform period is determined to be 10 microseconds in duration, what is the frequency of the signal?
- A. 1000 Hz
- B. 100 Hz
- C. 10 kHz
- D. 100 kHz
Answer: D
Explanation:
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.
