Cisco IT Essentials Chapter 2 exam questions

• 1.

### What class of fire extinguisher is used on an electrical fire?

• A.

Class A

• B.

Class B

• C.

Class C

• D.

Class D

C. Class C
Explanation
Class C fire extinguishers are specifically designed to extinguish fires involving electrical equipment. These extinguishers contain non-conductive agents, such as carbon dioxide or dry chemical, that do not conduct electricity. This is crucial in preventing electrical shock to the person using the extinguisher. Class C extinguishers are labeled with a blue circle and the letter "C" to indicate their suitability for electrical fires.

### Which types of clothing are likely to generate a static charge?

• A.

Wool

• B.

Cotton

• C.

Silk

• D.

All of the above

D. All of the above
Explanation
Wool, cotton, and silk are all likely to generate a static charge. These materials have the ability to rub against other surfaces and create friction, which leads to the buildup of static electricity. When two materials with different electrical properties come into contact and then separate, electrons can be transferred, resulting in a static charge. Therefore, all three types of clothing mentioned can generate a static charge.

### What is the minimum level of electrostatic discharge that a person can normally feel?

• A.

30 volts

• B.

300 volts

• C.

3000 volts

• D.

30,000 volts

C. 3000 volts
Explanation
The minimum level of electrostatic discharge that a person can normally feel is 3000 volts.

### Which recommendation should be followed first when a fire in the workplace is out of control?

• A.

Try to use the elevators or lifts to get out of the building

• B.

Try to get out of the room and contact the emgergency services

B. Try to get out of the room and contact the emgergency services
Explanation
When a fire in the workplace is out of control, the first recommendation that should be followed is to try to get out of the room and contact the emergency services. This is the most logical and practical course of action to ensure personal safety and to alert the appropriate authorities for immediate assistance. Trying to use elevators or lifts may be dangerous as they could malfunction or become inaccessible during a fire. Opening windows and jumping is also extremely risky and should be avoided. Running around screaming is not a helpful or productive response in such a situation.

### Which of these conditions refers to a dramatic increase in voltage, which is usally caused by lightening?

• A.

Pulse

• B.

Sag

• C.

Call the techies my PC is fried!

• D.

Spike

D. Spike
Explanation
A spike refers to a dramatic increase in voltage, usually caused by lightning. This sudden surge in voltage can potentially damage electrical equipment, including computers. It is important to protect electronic devices from spikes by using surge protectors or unplugging them during storms to prevent damage.

### What does ESD stand for?

• A.

Electrostatic detectives

• B.

Electrostatic dymanics

• C.

Electrostatic dummies

• D.

Electrostatic discharge

D. Electrostatic discharge
Explanation
ESD stands for Electrostatic Discharge. Electrostatic discharge refers to the sudden flow of electricity between two objects with different electrical potentials. It occurs when there is a buildup of static electricity on one object and it discharges to another object. ESD can cause damage to electronic components and devices, which is why measures such as grounding and ESD protection are important in handling sensitive electronics.

### What are the major causes of noise?

• A.

Generators and Lightening

• B.

Squeeky doors

• C.

Chris Moyles

• D.

Christmas bells

A. Generators and Lightening
Explanation
Generators and lightning are major causes of noise because they both produce loud and disruptive sounds. Generators, especially industrial ones, are known for their loud operation and can generate a constant noise that can be heard from a distance. Lightning, on the other hand, produces thunder, which is a loud noise caused by the rapid expansion of air due to the intense heat of the lightning bolt. Both generators and lightning can create significant noise pollution and can be disruptive to the surrounding environment.

### Which of these is a fact sheet that summarises information about material identicication?

• A.

MSFS

• B.

MIFS

• C.

MILFS

• D.

MSDS

D. MSDS
Explanation
MSDS stands for Material Safety Data Sheet, which is a fact sheet that provides essential information about a particular material or substance. It summarizes important details such as the material's identification, hazards, handling and storage instructions, emergency procedures, and more. MSDSs are commonly used in workplaces to ensure the safe handling and use of materials, and they are an important resource for employees to understand the potential risks associated with a substance and how to mitigate them.

### Which screwdriver should be used to remove screws that have a star-like depression on top?

• A.

Torox

• B.

• C.

Hex driver

• D.

Bus driver

A. Torox
Explanation
A Torox screwdriver should be used to remove screws that have a star-like depression on top. This type of screwdriver has a tip that matches the star-like shape of the screw, allowing for a secure and precise fit. Using any other type of screwdriver, such as a flat head or hex driver, may result in damage to the screw or the tool itself. A "Bus driver" is not a type of screwdriver and is not relevant to this question.
