NEW QUESTION # 27
AC is more easily distributed than DC. This is because:
- A. DC needs wires to be totally insulated, while AC wires can be bare, hung from insulator on pylons.
- B. Wires have less resistance if they are carrying AC
- C. AC can be transmitted using lighter wires.
- D. AC can be transformed from a low voltage to a high voltage and back again with a transformer. DC cannot.
Answer: D
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 # 28
Which one of the following uses sensors such as laser beams or touch sensor?
- A. Server
- B. Alarms
- C. CCTV
- D. Backup device
Answer: B
Explanation:
Explanation
Alarms are physical security devices that use sensors such as laser beams or touch sensors to detect movement or intrusion. These devices are used to alert the user of any unauthorized activity in the area. Alarms can also be used in combination with CCTV cameras to provide a comprehensive security system.
NEW QUESTION # 29
Which one of the following describes the amount of resistance electricity encounters?
- A. Ohm
- B. Volts
- C. Ampere
- D. Watts
Answer: A
Explanation:
Explanation
Ohm () describes the amount of resistance electricity encounters. It is one of the base units of the International System of Units (SI), and is defined as the amount of resistance that a conductor has when a force of one volt is applied across it. Ohms are used to measure the electrical resistance of a circuit, and can be used to determine the power of a circuit or the amount of current flowing through it.
NEW QUESTION # 30
Which system in Air Distribution System takes the hot exhaust air from the IT equipment to the CRAC
- A. Regulation system
- B. Maintenance system
- C. Supply system
- D. Return system
Answer: D
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 # 31
Which one of the following is an advantage of Air Cooled Self-Contained System?
- A. Lowest installation cost
- B. All components contain more than one unit
- C. It has more heat removal capacity per unit
- D. It doesn't requires ductwork and/or dropped ceiling
Answer: D
Explanation:
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.
NEW QUESTION # 32
Every air distribution system has a ____________ system and a _________ system
- A. Supply, Release
- B. Supply, Reverse
- C. Maintenance, Regulation
- D. Supply, Return
Answer: D
Explanation:
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.
NEW QUESTION # 33
If a waveform period is determined to be 10 microseconds in duration, what is the frequency of the signal?
- A. 100 kHz
- B. 1000 Hz
- C. 10 kHz
- D. 100 Hz
Answer: A
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 # 34
Which type of Circuit Breaker uses an electromagnetic coil to pull a switch when a circuit carries too much current?
- A. Static
- B. Thermal
- C. Pull
- D. Magnetic
Answer: D
Explanation:
Explanation
Magnetic circuit breakers use an electromagnetic coil to pull a switch when a circuit carries too much current, thus tripping the circuit and preventing it from exceeding its rated amperage.
NEW QUESTION # 35
___________ measures the amount of electrical current flowing through a circuit during a specific time interval.
- A. Ampere
- B. Volts
- C. Ohm
- D. Watts
Answer: A
Explanation:
Explanation
An ampere (A) is the unit of measurement for electric current. It measures the amount of electrical current flowing through a circuit during a specific time interval. The ampere is named after Andre-Marie Ampere, a French mathematician and physicist who was one of the main discoverers of electromagnetism.
Ohm () is the unit of measurement for electric resistance, which is the opposition to the flow of an electric current through a circuit.
Volt (V) is the unit of measurement for electric potential difference, which is the energy required per unit charge to move a test charge between two places in a static electric field.
Watt (W) is the unit of measurement for power, which is the rate at which energy is used or generated in an electrical circuit.
