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.2 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?
A. Do a system backup (complete) on each old machine, then restore it onto the new machines.
B. Copy the files and the Windows Registry to a removable media then copy it onto the new
machines.
C. Use the User State Migration tool to move the system settings and files to the new machines.

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.
NO.3 Which of the following is used by Wi-Fi Protected Access (WPA) to provide data encryption?
A. IDEA
B. TKIP
C. RSA
D. RC4
Answer: B
CompTIA antworten JK0-U11 Zertifizierungsantworten JK0-U11 Examsfragen JK0-U11 JK0-U11
Explanation:
TKIP (Temporal Key Integrity Protocol) is an encryption protocol defined in the IEEE 802.11i standard
for wireless LANs (WLANs). It is designed to provide more secure encryption than the disreputably
weak Wired Equivalent Privacy (WEP). TKIP is the encryption method used in Wi-Fi Protected Access
(WPA), which replaced WEP in WLAN products. TKIP is a suite of algorithms to replace WEP without
requiring the replacement of legacy WLAN equipment. TKIP uses the original WEP programming but
wraps additional code at the beginning and end to encapsulate and modify it. Like WEP , TKIP uses
the RC4 stream encryption algorithm as its basis.
NO.4 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
CompTIA zertifizierung JK0-U11 testantworten JK0-U11 Testfagen
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.5 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

NO.7 Which of the following is a circuit board that is used to extend slots for expansion cards and
provides the ability to connect additional expansion cards to the computer?
A. Audio/modem riser
B. Secure Digital (SD) card
C. Riser card
D. Communication and Networking Riser (CNR)
Answer: C
CompTIA testking JK0-U11 echte fragen JK0-U11 prüfungsvorbereitung JK0-U11 Antworten
Explanation:
Riser card is a circuit board that is used to extend slots for expansion cards and provides the ability
to connect additional expansion cards to the computer.
These cards are used with LPX motherboards. With the introduction of ATX motherboards, riser
cards are rarely used. In ATX motherboards, the expansion cards connect directly to the computer
motherboard instead of using riser cards.
Answer A is incorrect. The audio/modem riser (AMR), also known as an AMR slot, is an expansion
slot. It is found on the motherboards of some Pentium III, Pentium 4, and Athlon personal
computers. It was designed by Intel to interface with chipsets and provide analog functionality, such
as sound cards and modems, on an expansion card. It has two rows of 23 pins each, making a total
of 46 pins.
Answer D is incorrect. Communication and Networking Riser (CNR) is a hardware device developed
by Intel. It plugs into the motherboard and holds chips for the functioning of devices such as
modems and audio devices. It supports V.90 analog modem, multi-channel audio, phone-line-based
networking, and 10/100 Ethernet-based networking. CNR also minimizes electrical noise
interference through the physical separation of noise- sensitive elements from the motherboard's
communication systems.
Answer B is incorrect. Secure Digital (SD) card is a non-volatile memory card format used in portable
devices such as mobile phones, digital cameras, and handheld computers. SD cards are based on the
older MultiMediaCard (MMC) format, but they are a little thicker than MMC cards. Generally an SD
card offers a write-protect switch on its side. SD cards generally measure 32 mm x 24 mm x 2.1 mm,
but they can be as thin as 1.4 mm. The devices that have SD card slots can use the thinner MMC
cards, but the standard SD cards will not fit into the thinner MMC slots. Some SD cards are also
available with a USB connector. SD card readers allow SD cards to be accessed via many connectivity
ports such as USB, FireWire, and the common parallel port.
NO.8 Which of the following is designed to infiltrate or damage a computer without the consent of
the owner?
A. Shareware
B. Malware
C. Freeware
D. Stealware
Answer: B
CompTIA originale Fragen JK0-U11 prüfungsunterlagen JK0-U11 testantworten JK0-U11 Prüfungsfragen
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.
