CompTIA対策 JK0-U11攻略 JK0-U11費用
Explanation:
The Computer Misuse Act 1990 is an act of the UK Parliament which states the following statement:
Unauthorized access to the computer material is punishable by 6 months imprisonment or a fine
"not exceeding level 5 on the standard scale" (currently 5000). Unauthorized access with the intent
to commit or facilitate commission of further offences is punishable by 6 months/maximum fine on
summary conviction or 5 years/fine on indictment. Unauthorized modification of computer material
is subject to the same sentences as section 2 offences.
Answer B and C are incorrect. These two statements are stated in the Data Protection Act 1998.
NO.3 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費用 JK0-U11難易度 JK0-U11問題集 JK0-U11問題
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.4 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会場 JK0-U11テスト JK0-U11合格率
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.
NO.5 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番号 JK0-U11赤本 JK0-U11教育
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.6 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受験記 JK0-U11赤本 JK0-U11フリーク JK0-U11独学 JK0-U11赤本
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.7 You are working in a Windows network environment. Which of the following accounts/groups
have many advanced permissions not needed by occasional users?
Each correct answer represents a part of the solution. Choose two.
A. Guest
B. Standard user
C. Administrator
D. Power Users
Answer: D,C
CompTIA会場 JK0-U11割引 JK0-U11独学 JK0-U11教本
Explanation:
An Administrator user account has full permissions on the computer.
The Power Users group has many advanced permissions not needed by occasional users.
Power users can perform any tasks except those reserved for administrators.
Answer B is incorrect. A Standard user account has a minimal set of permissions.
Each account in standard user mode is designed to store a separate set of settings for users.
The users are allowed to launch applications, create new documents, and modify basic system
configurations.
Answer A is incorrect. A Guest account is designed to provide temporary access to computers.
It does not store user-specific profile settings permanently. This account is disabled by default.
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?
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.
D. Use the Disk Management tool to move everything to the new computer.
Answer: C
CompTIA体験 JK0-U11方法 JK0-U11認定資格 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.
