Chapter 9: Operational Procedures Flashcards
Which if the following is the technical term for what happens whenever two objects of dissimilar charge come in contact?
A. RFI
B. EMI
C. ESD
D. LED
C. ESD
Electrostatic discharge (ESD) is the technical term for what happens whenever two objects of dissimilar charge come in contact—think of rubbing your feet on a carpet and then touching a light switch.
Which if the following is NOT a safe lifting technique to keep in mind?
A. Lift with your back, not your legs
B. Be careful to not twist when lifting
C. Keep objects as close to your body as possible
D. Where possible, push instead of pull
A. Lift with your back, not your legs
Lift with your legs, not your back. When you have to pick something up, bend at the knees, not at the waist
What class of fire extinguisher is used for paper fires?
A. A
B. B
C. C
D. D
A. A
A for wood and paper fires, B for flammable liquids, and C for electrical fires.
Any type of chemical, equipment, or supply that has the potential to harm the environment or people has to have what document associated with it?
A. SOW
B. MSDS
C. SLA
D. MOU
B. MSDS
Any type of chemical, equipment, or supply that has the potential to harm the environment or people has to have a material safety data sheets (MSDS) associated with it. These are traditionally created by the manufacturer, and you can obtain them from the manufacturer or from the Environmental Protection Agency
What humidity level should be maintained for computing equipment?
A. 50 percent
B. 40 percent
C. 60 percent
D. 30 percent
A. 50 percent
Another preventive measure you can take is to maintain the relative humidity at around 50 percent. Be careful not to increase the humidity too far—to the point where moisture starts to condense on the equipment!
Which if the following is a complete failure of the power supplied?
A. sag
B. spike
C. blackout
D. brownout
C. blackout
There are a number of power-related threats that can harm computers. Among them are the following:
- Blackout: A complete failure of the power supplied.
- Brownout: A drop in voltage lasting more than a few minutes.
- Sag: A very short-term voltage drop.
- Spike: The opposite of a sag, this is a short (typically under 1 second) increase in voltage that can do irreparable damage to equipment.
- Surge: A long spike (sometimes lasting many seconds). Though they are typically a less intense increase in power, they can also damage equipment.
How should you use compressed air to clear duct?
A. in long bursts
B. in slow steady burst
C. in short bursts
D. never use it
C. in short bursts
The short bursts are useful in preventing the dust from flying too far out and entering another machine, as well as in preventing the can from releasing the air in liquid form
Which if the following is a drop in voltage lasting more than a few minutes?
A. sag
B. spike
C. blackout
D. brownout
D. brownout

Which if the following outlines what steps are needed and who is responsible for deciding how to handle a situation?
A. SOW
B. SLA
C. MOU
D. IRP
D. IRP
Because knowing what to do when something is discovered is something that may not come naturally, it is a good idea to include the procedures you’ll generally follow in an incident response plan (IRP). The IRP outlines what steps are needed and who is responsible for deciding how to handle a situation.
Which if the following is a very short-term voltage drop?
A. sag
