NO.1 Which of the following parts of the computer is built-in to the motherboard?
A. Joystick
B. Mouse
C. Sound card
D. CD-ROM drive
Answer: C
certification CompTIA JK0-U11 JK0-U11
Explanation:
Sound cards are built-in to the motherboard. Sound card enables the computer to output sound to
audio devices, as well as accept input from a microphone. Most modern computers have sound
cards built-in to the motherboard, though it is common for a user to install a separate sound card as
an upgrade.
Answer D is incorrect. CD- ROM is a device used for reading data from a CD. This device is not built-
in to the mother board.
Answer B is incorrect. Mouse is a pointing device that detects two dimensional motion relative to its
supporting surface. This device is not built-in to the mother board.
Answer A is incorrect. Joystick is a device mostly used in gaming. It consists of a handheld stick that
pivots around one end, to detect angles in two or three dimensions.
NO.2 You are selecting memory to put in to a laptop. Which of the following types of RAM chips
would you most likely select?
A. 72 PIN
B. 240 PIN
C. 184 PIN
D. 144 PIN
Answer: D
CompTIA examen JK0-U11 examen certification JK0-U11 certification JK0-U11 JK0-U11 examen
Explanation:
Both MicroDIMM and SO-DIMM come in a 144 pin configuration, and are used for laptops.
NO.3 Which of the following slots on a motherboard are best for a video card? Each correct answer
represents a complete solution. Choose two.
A. PCI
B. PCIe
C. EISA
D. AGP
Answer: D,B
certification CompTIA JK0-U11 examen certification JK0-U11
Explanation:
AGP and PCIe are the best slots for a video card. PCI Express (PCIe), also known as 3rd Generation
I/O (3GIO), is a type of computer bus. It is a new I/O bus technology that has more bandwidth than
PCI and AGP slots. It uses two low-voltage differential pairs, at 2.5Gb/s in each direction. It is
designed to replace PCI and AGP expansion slots. The bus is available in several different bus widths:
x1, x2, x4, x8, x12, x16, and x32. PCIe is able to transfer data in both directions at a time. PCIe
hardware will work on operating systems that support PCI. AGP is a high speed 32-bit bus designed
for high performance graphics and video support. It allows a video card to have direct access to a
computer's RAM, which enables fast video performance. AGP provides a bandwidth of up to 2,133
MB/second.
Answer C is incorrect. The Extended Industry Standard Architecture (EISA) is a 32-bit PC expansion
bus designed as a superset of a 16-bit ISA bus. The EISA bus is designed to increase the speed and
expand the data width of the legacy expansion bus while still supporting older ISA cards. EISA slots
are obsolete now.
Answer A is incorrect. PCIe and AGP slots are better than PCI slot for a video card.
NO.4 Which of the following statements about a smart card are true? Each correct answer
represents a complete solution. Choose two.
A. It is a device that contains a microprocessor and permanent memory.
B. It is used to securely store public and private keys for log on , e-mail signing and encryption, and
file encryption.
C. It is a device that routes data packets between computers in different networks.
D. It is a device that works as an interface between a computer and a network.
Answer: A,B
CompTIA JK0-U11 examen certification JK0-U11 JK0-U11 examen
Explanation:
A smart card is a credit card-sized device that contains a microprocessor and permanent memory. It
is used to securely store public and private keys for log on, e- mail signing and encryption, and file
encryption. To use a smart card, a computer must have a smart card reader attached with it.
NO.5 Which of the following refers to the data rate supported by a network connection or
interface?
A. Spam
B. Preboot Execution Environment (PXE)
C. Bandwidth
D. Branding
Answer: C
CompTIA examen JK0-U11 examen JK0-U11 examen JK0-U11
Explanation:
Bandwidth is a term that refers to the data rate supported by a network connection or interface.
Bandwidth (or digital bandwidth) is a measurement of how much data can be sent in a period of
time. It is a data rate measured in bits. The standard unit of digital bandwidth is bits per second
(bps). In radio communication,
bandwidth (analogue bandwidth) is the range of frequencies occupied by the radio signals. The
standard unit of analogue bandwidth is Hertz (Hz).
Answer D is incorrect. In Web site designing, branding refers to the look and feel of a Web site.
Branding helps in differentiating a site from its competitors and also helps the customer to develop
a relationship with the Web site. The look and feel of a Web site comes through logo, fonts, color
schemes, and symbols used in the Web site. The overall look of the Web site should be consistent.
Answer B is incorrect. Preboot Execution Environment (PXE) is an environment to boot computers
using a network interface independently of available data storage devices like hard disks or installed
operating systems. PXE is also known as Pre-Execution Environment.
Answer A is incorrect. Spam is a term that refers to the unsolicited e-mails sent to a large number of
e-mail users. The number of such e-mails is increasing day by day, as most companies now prefer to
use e-mails for promoting their products. Because of these unsolicited e- mails, legitimate e-mails
take a much longer time to deliver to their destination. The attachments sent through spam may
also contain viruses. However, spam can be stopped by implementing spam filters on servers and
e-mail clients.

the owner?
A. Shareware
B. Malware
C. Freeware
D. Stealware
Answer: B
CompTIA certification JK0-U11 certification JK0-U11 certification JK0-U11
Explanation:
The term malware refers to malicious software, which is a broad class of malicious viruses, including
spyware.
Malware is designed to infiltrate or damage a computer without the consent of the owner.
Answer D is incorrect. Stealware is associated with Web bugs or spyware.
It is used by Web sites to affiliate marketing programs. Stealware attributes can be present in
peer-to-peer software applications. Spyware, adware, and stealware are similar types of malicious
code. Some Websites are advertised as free and allow information to be downloaded.
However, a pop-up window with a disclaimer should appear.
The disclaimer discloses information of possible charges or rerouting of the Web site. The users
should read the disclaimer to learn what charges are applicable before clicking the advertisement.
Otherwise, they will be liable to pay a large sum of money. The working procedure of stealware is
shown in the figure below:
Answer A is incorrect. Shareware is software designed to use freely or for a limited period available
on the Internet. After completing the given time, the user can either purchase it or legally remove it.
These types of products are usually offered either with certain features only available when the user
has purchased the product, or as a full version but for a limited trial period of time.
Answer C is incorrect. Freeware is computer software that can be used without paying for it.
NO.8 You are working with a team that will be bringing in new computers to a sales department at a
company.
The sales team would like to keep not only their old files, but system settings as well on the new
PC's. What should you do?

D. Use the Disk Management tool to move everything to the new computer.
Answer: C
certification CompTIA certification JK0-U11 JK0-U11 examen JK0-U11
Explanation:
The User State Migration Tool is made specifically for this purpose. Large scale migrations require
not only files but system settings to be moved to new machines and Microsoft created this tool for
this purpose.
