Get Familiar With CompTIA Exam 220-601: A+ Essentials

These practice test questions from MeasureUp are based on CompTIA exam 220-601: A+ Essentials .

The audience for this exam includes individuals who are in the early stages of a career in information technology (IT) and those who plan to start a career in IT. This includes positions such as computer technicians, desktop support technicians and help-desk technicians. Experience installing, configuring and supporting computer hardware, computer software and networks will help you prepare for this exam.

Passing exam 220-601 and exam 220-602, 220-603 or 220-604 earns a candidate one of the certifications required by the U.S. Department of Defense (DOD) Directive 8570.1. This directive mandates that both DOD employees and contractors who work with the DOD on any security-related initiative must receive proper training and earn one or more network-related and security-related certifications.

Objective: Laptops and portable devices.
Sub-objective: Install, configure, optimize and upgrade laptops and portable devices.

You need to configure power management for your laptop computer. The computer is running Microsoft Windows XP Professional. You need to ensure that when the computer sits idle for more than 15 minutes, the computer powers down and turns itself off. You also need to be able to bring the computer back to being fully functional and available with the same applications running as before the computer was turned off.

You need to bring the computer back up as quickly as possible when it is turned back on. Which power state should you have the computer enter after it sits idle for 15 minutes?

A.    Shutdown.
B.    Suspend.
C.    Hibernate.
D.    Standby.

Answer:
C

Tutorial:
You should have the computer enter the hibernate state after it sits idle for 15 minutes. When a computer hibernates, all running applications and data in RAM are written to the hard disk. The computer power is then turned off. When the computer is turned back on, it is able to come back to full functionality with the same applications running because it reads the applications and data from the hard disk and writes them back into memory.

Shutdown also turns off the computer but does not write the running applications or data to the hard disk. Because nothing is written to the hard disk, when the computer is turned on, it must go through full operating system start-up. You must then restart any applications and reopen any data files you need. This means it takes longer to get the computer back to the same state as before it shut down.

Both suspend and standby are low-power states. Neither suspend nor standby turns the computer off, so neither of these power options meets your requirements.

Suspend is a low-power state with applications and memory maintained in RAM but not written to the hard disk. Suspend does not turn off the computer but does turn off many components in the computer, such as the hard disk.

Nothing is saved to memory or the hard disk with standby, and fewer devices are turned off (if any) than with the suspend mode. Some devices, such as the processor, are put in a lower-power mode. Because there are fewer devices that must be turned back on than with other power states, the computer returns to full functionality from this state faster than from any of the others listed.

You have an application that needs to print on a multipart carbonless form. The form is a multifold pin feed, with multiple sheets per box and perforations at each fold to make it easy to tear the forms apart. What kind of printer should you use?

A.    Standard laser printer.
B.    Ink-jet printer.
C.    Color image laser printer.
D.    Dot matrix printer.

Answer:
D

Tutorial:
You should use a dot matrix printer. A dot matrix printer is an impact printer. It forms an image when pins strike an inked ribbon, which in turn strikes the paper. A dot matrix printer also can make an image on multiple copies because of the mechanical force involved.

You should not use a laser or ink-jet printer. Neither of these is an impact printer. Because the image is not created by an impact, nonimpact printers would print on the top copy only.

A laser printer forms an image by using a charged drum to transfer toner to the paper. The toner is then fused in place by heat. In a color laser printer, multiple toner layers are applied to create the colors. Also, most laser printers do not support multifold papers.

An ink-jet printer forms an image by squirting ink through tiny holes in a print head onto the paper. Most ink-jet printers do not support multifold papers.

Sub-objective: Describe the aspects and importance of safety and environmental issues.

Why should an MSDS be kept with or near the hazardous material it describes? (Choose two.)

A.    The MSDS describes when and how the material should be used.
B.    The MSDS describes health effects and first aid procedures.
C.    The MSDS must be destroyed when the material is disposed of or destroyed.
D.    The MSDS describes proper handling and storage procedures.

Answer:
B, D

Tutorial:
You should keep the material safety data sheet (MSDS) with or near the hazardous material it describes because it describes proper handling and storage procedures. It also describes health effects and first aid procedures. Should someone come in contact with the material, this information could be critical. Emergency personnel often will ask for the MSDS if there is an accident.

The MSDS typically does not describe when and how the material should be used. This would be contained in other documentation, which you should also keep available, though not necessarily close at hand.

You usually will not destroy the MSDS when the material is disposed of or destroyed. Instead, it must be kept on file as a record of the disposition of the material. When you hand the hazardous material over to a professional waste disposal company, you will usually also hand over the MSDS, or at least a copy of the MSDS.

You need to add some memory to your laptop computer. What type of memory would you typically use?

A.    SODIMM.
B.    DIMM.
C.    SIMM.
D.    RAMBUS.

Answer:
A

Tutorial:
Most laptop computers use SODIMM memory, which is similar to the DIMM format, but is smaller. 200-pin SODIMMs use DDR PC2100, PC2700 and PC3200 SDRAM and DDR2 PC2-4200 SDRAM.

SIMMs were used in early Macintosh computers and 386 and 486-class PCs and early Pentium PCs.

DIMMs are used in desktop computers using Athlon and Pentium processors.

Rambus is a memory technology that seeks to replace DRAM. It is not typically used in laptop computers and has not achieved much market penetration.

Which IP address is a valid host address?

A.    192.168.0.256
B.    00-03-A6-98-03-16
C.    10.10.10.10
D.    A87E34B2

Answer:
C

Tutorial:
An Internet Protocol (IP) address is a 32-bit number sequence, divided into four octets, each separated by a decimal point. The number in each octet can range from zero to 255 with some restrictions. The IP address is a combination of network number and host number.

10.10.10.10 is a valid IP address. It represents network 10.0.0.0 and host 10.10.10.

The 192.168.0.256 is not a valid address because the last octet is 256, which is not possible in 8-bits.

00-03-A6-98-03-16 is not an IP address but a Media Access Control (MAC) address that is a burned in address on the network card.

A87E34B2 is representative of an Internet Packet Exchange (IPX) network address. In an IPX network, an 80-bit address is used, and it is written in hexadecimal notation.
