NEW QUESTION # 22
__________ represents the maximum power cable of being drawn by the equipment.
- A. VA rating
- B. Grade rating
- C. Star rating
- D. Power rating
Answer: D
Explanation:
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.

NEW QUESTION # 29
Which system in Air Distribution System takes the hot exhaust air from the IT equipment to the CRAC
- A. Return system
- B. Regulation system
- C. Maintenance system
- D. Supply system
Answer: A
Explanation:
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.
NEW QUESTION # 30
If a waveform period is determined to be 10 microseconds in duration, what is the frequency of the signal?
- A. 100 Hz
- B. 100 kHz
- C. 1000 Hz
- D. 10 kHz
Answer: B
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.

NEW QUESTION # 37
Which one of the following controls the voltage produced at the output of the alternator?
- A. Voltage Stabilizer
- B. Voltage Backup Device
- C. Voltage Regulator
- D. Voltage Meter
Answer: C
Explanation:
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.
NEW QUESTION # 38
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.
