Learn About Depot Technician

These practice test questions from MeasureUp are based on CompTIA's exam 220-604: Depot Technician .

The audience for this exam includes individuals who are in the early stages of a career in information technology (IT). This includes positions such as technicians who work in a parts depot assembling computers. Experience with installing, configuring, supporting and troubleshooting computer hardware and software will help you prepare for this exam.

To earn the Depot Technician certification, you must pass both exam 220-604 and exam 220-601 (CompTIA A+ Essentials). MeasureUp also has a practice test for exam 220-601.

What is the best way to prevent physical sabotage to critical server systems?

A.    Use external hard disks for storage and keep the disks physically separate from the servers.
B.    Keep critical servers in a locked room with limited access.
C.    Physically secure systems with a cable lock to prevent them from being moved.
D.    Warn users not to touch the servers.

Answer:
B

Tutorial:
You should keep critical servers in a locked room with limited access. This limits physical access to the servers and provides a relatively high level of physical security, making it more difficult for someone to physically sabotage the systems. Physical sabotage is any action that physically damages the computer.

You should not use external hard disks for storage and keep the disks physically separate from the servers as a way to prevent physical sabotage to critical server systems. This makes it moderately more difficult to locate the servers and their storage media, but it does nothing to provide physical protection for the servers.

You should not physically secure systems with a cable lock to prevent them from being moved as a way to prevent physical sabotage to critical server systems. This does prevent the computers from being moved, but it does nothing to prevent someone from causing physical damage to the computers while they are in place.

You should not warn users not to touch the servers as a way to prevent physical sabotage to critical server systems. While you should do this as a way of informing users of the policy about these servers, it does nothing to physically protect the computers from sabotage.

Single answer, multiple-choice

A user has a laptop computer with two Type II PCMCIA card slots, one on top of the other. How many Type III hard-disk PC cards can the user install in the laptop?

A.    0
B.    1
C.    2
D.    4

Answer:
B

Tutorial:
All Portable Computer Memory Card International Association (PCMCIA) cards use the same 68-pin interface. The difference between Type I, Type II and Type III cards is their height (thickness). A Type I card is 3.3 mm, a Type II card is 5.0 mm, and a Type III card is 10.5 mm. When the laptop has two Type II card slots, it can hold one Type III card, two Type II cards or two Type I cards.

A laser printer is experiencing paper jams. What should you do?

A.    Clean the rubber guide rollers using alcohol on a fibrous cleaning towel.
B.    Replace the fuser assembly.
C.    Clean the fuser assembly roller with water on a fibrous cleaning towel.
D.    Use the maintenance software to realign the guide rollers.

Answer:
A

Tutorial:
You should clean the rubber guide rollers using alcohol on a fibrous cleaning towel. The guide rollers are responsible for moving the paper through the printer. They should be a little rough but clean. When they get dirt or paper dust on them, it can cause paper jams. You can clean them using alcohol on a fibrous cleaning towel. If they become too smooth, you can use alcohol on a nonmetallic scouring pad to make them rough so they work better.

Replacing the fuser assembly will not resolve the problem. The fuser assembly is used to fuse ink to the paper, not to move the paper through the printer.

You should not clean the fuser assembly roller with water on a fibrous cleaning towel. A dirty fuser assembly roller is not the problem. Also, you should not use a fibrous cleaning towel and water to clean the fuser assembly roller. You should use alcohol and a soft cloth. You must be very careful not to scratch the fuser assembly roller.

You should not use maintenance software to realign the guide rollers. Ink jet printers include maintenance software that can be used to realign the print heads. Laser printers have maintenance kits that contain spare parts.

Sub-objective: Identify potential hazards and proper safety procedures, including power supply, display devices and environment (e.g., trip, liquid, situational, atmospheric hazards, high-voltage and moving equipment).

When should a technician wear an antistatic strap?

A.    When discharging the cathode ray tube in a CRT display.
B.    When moving computers and displays.
C.    When replacing components inside a power supply.
D.    When installing memory in a desktop computer.
 
Answer:
D

Tutorial:
A technician should wear an antistatic strap when installing memory in a desktop computer. An antistatic strap, when properly grounded, ensures the technician and equipment are at the same static potential. The antistatic strap helps to prevent a static discharge that could damage the memory.

You should not wear an antistatic strap when discharging the cathode ray tube in a CRT display or when replacing components inside a power supply. In both situations, there is a potential for a hazardous or even fatal shock. This potential is increased when wearing an antistatic strap because it might accidentally complete the electric circuit.

You should not wear an antistatic strap when moving computers and displays. The antistatic strap does not provide any extra protection and puts the technician at a higher risk. The strap, if loose, might cause the technician to trip or could get caught on something and cause the technician to drop the equipment. This could damage the equipment or injure the technician.

A user reports random system hangs and crashes. After asking some questions, you determine that the user's office is very hot.

What should you tell the user to do to keep the system cool?

A.    Keep the case open.
B.    Remove the slot covers from empty slots.
C.    Make sure empty slots have slot covers.
D.    Remove the cover from the spare drive bay.

Answer:
C

Tutorial:
You should tell the user to make sure empty slots have slot covers. Fans and vents are specifically designed to help the computer stay cool by directing warm air to flow out the vents at the top of the computer as it rises. Therefore, you should keep additional openings closed. This includes the empty slots.

You should not keep the case open. Doing so defeats the air flow design and exposes the components to environmental dangers, such as dust and liquids.

You should not remove the slot covers from the empty slots. Doing so will prevent the air flow from working as designed.

You should not remove the cover from the spare drive bay. Doing so will prevent the air flow from working as designed.
