A video adapter resolution of 800x600 would represent which video standard?

1. CGA

2. VGA

3. SVGA

4. Monochrome

Correct Answer = C.

As displayed in Table 6.2, a resolution of 800x600 is supported by SVGA. CGA supports 320x200 and 640x200. VGA supports 640x480 and 320x200. Monochrome supports 720x350.

Which of the following refers to the amount of time that it takes for the electron gun to redraw the display?

1. Interlace

2. Refresh rate

3. Dot pitch

4. Pixel triad

Correct Answer = B.

The electron gun inside the CRT must redraw the image continuously in order to keep the phosphors active. This process is called a CRT's refresh rate. Interlace, or interlacing, is a video technique used to scan all odd-numbered lines in succession of a video display, followed by the even lines. Dot pitch is the distance measured between pixels. A pixel triad is the combination of the three electron beams projected from the electron gun to form a triangular representation of the three primary colors.

What would a bent or broken DB-15 male connector pin cause?

1. FRU displacement

2. Monitor problems

3. 800x600 pixels

4. Fragmentation

Correct Answer = B.

A DB-15 male connector is used to plug a monitor into a computer system. If one of the pins on this connector is bent or broken, you will most likely experience monitor problems. Fragmentation refers to files being stored on a hard disk in noncontiguous clusters.

You should not use this while working on a monitor. However, you should use this when installing a video adapter card. What is it?

1. An electron gun

2. Antiphosphorous beam

3. A multimeter

4. An ESD wrist strap

Correct Answer = D.You should never wear an ESD wrist strap while working with the components inside of a monitor. An electronic reaction may occur that can be deadly. You should, however, wear a protective wrist strap while installing adapter cards in your system to protect them from ESD. An electron gun is used in a monitor to direct an electronic beam to the back of a glass screen that has a phosphorous coating. A multimeter is a device used to measure wattage.

You have changed your display settings while using Windows 98 and have rebooted your system. Windows will not come up. What mode would you use to troubleshoot this problem?

1. 386 enhanced mode

2. Safe Mode

3. Graphics mode

4. SVGA mode

Correct Answer = B.

You can enter Windows 98 Safe Mode by pressing the F5 key on boot up. Safe Mode loads a generic VGA driver for basic video. This will allow you to re-enter the operating system and change your video adapter driver and display settings as needed. The 386 enhanced mode is a processor mode introduced with the Intel 80386 processor that allows Windows 3.x to offer multitasking abilities.

Which of the following are printer consumable items? (Choose Three)

1. Platen

2. Print buffer

3. Toner cartridges

4. Printer drivers

5. Printer paper

6. Printer ribbons

Correct Answers = C, E, and F.

Toner cartridges, paper, and disposable ribbons are considered printer consumable items.

Several users have been trying to print reports to a networked printer. The users complain that their reports are not printing. What would you do to solve this issue?

1. Press the reset button on the printer.

2. Go into Safe Mode and remove the print driver.

3. Realign the platen.

4. Delete the reports from the printer queue (buffer). Then, stop and start the print spooler service.

Correct Answer = D.

With a networked printer, print jobs are typically queued in a printer buffer that is managed by the print spooler service. If print jobs are not printing to a networked printer, this process will clear the print queue and allow print jobs to be resubmitted and printed.

Your printed output appears to be fading from left to right. What is causing this problem?

1. The printer ribbon is old.

2. Your print driver is outdated.

3. The platen is out of alignment.

4. The print head is wearing out.

Correct Answer = C.

A misaligned platen commonly results in a faded level of ink application to the paper as it is applied from left to right, or it may result in uneven lines of output across the paper.

A laser printer is producing inconsistent, wavy output. What is a very common cause associated with this problem?

1. The rollers are broken.

2. The fuser is damaged.

3. The platen is out of alignment.

4. The toner cartridge is empty.

Correct Answer = D.

If your laser printer output begins to appear wavy or inconsistent, you may have an empty or malfunctioning toner cartridge.

Of the following choices, which uses a heat-sensitive print head that moves over a ribbon of transparent colored film?

1. Color impact

2. Dye sublimation

3. Laser transformation

4. Ink dispersion

Correct Answer = B.

With a dye sublimation printer, a heat-sensitive print head moves over a ribbon of transparent film that contains heat-activated inks.

Dye sublimation uses a heat-sensitive ribbon or film that is made up of the primary printing colors. What are the four primary printing colors?

1. Magenta, black, yellow, and blue

2. Yellow, blue, black, and red

3. Cyan, magenta, yellow, and black

4. Red, white, blue, and magenta

Correct Answer = C.

With a dye sublimation printer, a heat-sensitive print head moves over a ribbon of transparent film that contains heat-activated inks or sections that represent the four primary printing colors of cyan, magenta, yellow, and black (CMYK). All other choices are invalid.

Which of the following is considered the newest and fastest form of connectivity for printers?

1. Serial

2. USB

3. Parallel

4. ECP

5. ECC

Correct Answer = B.

Currently, the fastest available connection for a printer is realized through USB technology and a USB connection.

What should you check first if a printer has no paper, but there is an error code on a printer LED that states there is a paper jam?

1. Paper-feed sensors

2. USB port

3. Drum

4. Platen

5. Ink cartridge

Correct Answer = A.

Paper-feed rollers have sensors to control the proper flow of paper out of the paper tray. It is a common occurrence to receive a 'paper jam' error on the printer LED display; but on investigation, you find that there is no paper in the tray.

What acronym describes a multifunction device that is used to print, scan, copy, and fax?

1. CMYK

2. NLD

3. CMY

4. NLQ

5. MFD

Correct Answer = E.

An MFD is a device that combines the functionality of a printer, copier, scanner, and fax machine into one unit.

Which of the following are common features of a multifunctional finisher?

1. Ability to stack multiple sheets of letter- or ledger-size paper

2. Ability to fold single pages

3. Ability to stack sheets into booklets

4. Ability to staple sheets of letter- or ledger-size paper

5. All of the above

Correct Answer = E.

All of the items listed are common features of a multifunctional finisher.

What is the smallest monitor (in terms of size) that can be used to display 1600x1200?

1. 15-inch CRT

2. 17-inch CRT

3. 19-inch CRT

4. 17-inch LCD

Correct Answer = C.

The 15-inch CRT can typically only display up to 1024x768. The 17-inch CRT and LCD can only do 1280x1024 (just because the screen is a true 17-inch screen, you are still limited to 1280x1024).

Which one of these statements is true (assuming that the refresh rate listed is the maximum the monitor could handle at the given resolution)?

1. A 15-inch monitor, running at 1024x768 at a refresh rate of 65Hz, is capable of displaying 1280x1024 at 60Hz.

2. A 17-inch monitor that can handle 1280x1024 at 80Hz is more than likely capable of handling 1024x768 at approximately 95Hz-100Hz.

3. A 19-inch monitor that displays 1024x768 at 80Hz is more than likely capable of handling 1600x1200 at 85Hz.

4. None of the above.

5. All of the above.

Correct Answer = B.

A 15-inch monitor is not capable of 1280x1024. (The smallest monitor capable of 1280x1024 is a 17-inch monitor.) The 19-inch monitor running 1024x768 at 80Hz could probably display 1600x1200-but not at a higher refresh rate than running at 1024x768!
