NEW QUESTION 13
Which one of the following describes the amount of resistance electricity encounters?
- A. Ohm
- B. Watts
- C. Volts
- D. Ampere
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 14
For which one of these processes is Direct Current essential, and will not work with alternating current?
- A. Heating
- B. Electrolysis
- C. Turning a motor
- D. Lighting
Answer: B
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 15
Which mounted system is used to cool small IT environments?
- A. Chilled Mounted System
- B. Air Mounted System
- C. Floor Mounted System
- D. Ceiling Mounted System
Answer: B
Explanation:
Explanation
An air mounted system is often used to cool small IT environments. This type of cooling system is typically mounted on the wall or ceiling and works by blowing cool air into the room to lower the temperature. Air mounted systems are compact, easy to install and maintain, and can be a cost-effective solution for small spaces.
NEW QUESTION 16
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 17
Which one of the following controls the voltage produced at the output of the alternator?
- A. Voltage Meter
- B. Voltage Stabilizer
- C. Voltage Regulator
- D. Voltage Backup Device
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 18
Which one of the following is a Physical Security Identification Method?
- A. Batch ID
- B. Voice
- C. Expression
- D. Sound
Answer: B
Explanation:
Explanation
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.
NEW QUESTION 19
Which one of the following is a disadvantage of Water Cooled System?
- A. Usage of the building's condenser water is less expensive than chilled water
- B. Introduces an additional source of liquid
- C. All components are located inside the CRAC
- D. Condenser water piping loops long distances
Answer: B
Explanation:
Explanation
Water cooled systems introduce an additional source of liquid, which can be a potential source of contamination and damage to the IT equipment. Additionally, water cooled systems require more maintenance than air cooled systems and are more expensive to install due to the additional cost of the cooling tower, piping, and pumps.
NEW QUESTION 20
True or False: Fuel availability generally dictates the type of standby generator selected
- A. True
- B. False
Answer: A
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 21
A typical data center load would consist of _____ (Choose 3)
- A. Cooling equipment
- B. Software
- C. Power generator
- D. Computers
- E. Networking equipment
Answer: A,C,D

NEW QUESTION 23
Which component is designed to protect electrical equipment from damage caused by overload or short circuit?
- A. Transfer Switch
- B. Circuit Breaker
- C. Transient
- D. Stabiliser
Answer: B
Explanation:
Explanation
A circuit breaker is a device designed to protect electrical equipment from damage caused by overload or short circuit. Circuit breakers are designed to detect when too much current is flowing through a circuit and to shut the circuit off when that happens. This protects the equipment from damage due to overloading or short circuiting, and it also helps prevent fires and other accidents.
