NO.1 You are implementing wireless access at a defense contractor.
Specifications say, you must implement the AES Encryption algorithm. Which encryption standard
should you choose?
A. WEP
B. WPA
C. TKIP
D. WPA 2
Answer: D
CompTIA JK0-U31자격시험 JK0-U31자격증
Explanation:
WPA 2 (Wi Fi Protected Access 2) uses AES encryption, which is endorsed by the National Security
Administration. What is AES? The Advanced Encryption Standard (AES) is an encryption standard
adopted by the U.S. government. The standard comprises three block ciphers, AES-128, AES-192,
and AES-256. Each AES cipher has a 128-bit block size, with key sizes of 128, 192, and 256 bits,
respectively. The AES ciphers have been analyzed extensively and are now used worldwide, as was
the case with its predecessor, the Data Encryption Standard (DES). AES was announced by National
Institute of Standards and Technology (NIST) as U.S. FIPS PUB 197 (FIPS 197) on November 26, 2001
after a 5-year standardization process in which fifteen competing designs were presented and
evaluated before Rijndael was selected as the most suitable. It became effective as a standard on
May 26, 2002. As of 2009, AES is one of the most popular algorithms used in symmetric key
cryptography. It is available in many different encryption packages. AES is the first publicly
accessible and open cipher approved by the NSA for top secret information. Answer optiond A and
B are incorrect. WEP and WPA both use the RC-4 Stream cipher. What is RC4? RC4 is a stream cipher
designed by Ron Rivest.
It is used in many applications, including Transport Layer Security (TLS), Wired Equivalent Privacy
(WEP), Wi-Fi Protected Access (WPA), etc. RC4 is fast and simple. However, it has weaknesses that
argue against its use in new systems. It is especially vulnerable when the beginning of the output
key stream is not discarded, nonrandom or related keys are used, or a single key stream is used
twice. Some ways of using RC4 can lead to very insecure cryptosystems such as WEP . Answer option
C is incorrect. Temporal Key Integrity Protocol is a substitute for WPA, meant to replace WEP
without requiring that hardware be replaced.

of expansion card should you use?
A. MCA
B. PCMCIA
C. PCI
D. AGP
Answer: B
CompTIA pdf JK0-U31시험 JK0-U31 JK0-U31강좌 JK0-U31덤프
Explanation:
PCMCIA is a widely used expansion card slot for laptops. What is PCMCIA card? Personal Computer
Memory Card International Association (PCMCIA) card is also known as PC card. The PC card uses a
small expansion slot and is primarily used in laptops. However, PC cards are also available in some of
the desktop computers. There are three types of PCMCIA cards. 1.Type I 2.Type II 3.Type III Answer
option C is incorrect. PCI slots are used in PC's, not laptops. Answer option D is incorrect. AGP is a
legacy
graphics slot for PC's. What is AGP (Accelerated Graphics Port)? 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 option A is incorrect. MCA is a legacy PC slot.

NO.3 Which of the following programs can collect various types of personal information,
such as Internet surfing habits, and Web sites that the user has visited?
A. Malware
B. Spyware
C. Honeypot
D. Worm
Answer: B
CompTIA JK0-U31 JK0-U31기출문제
Explanation:
Spyware is a program that takes partial control over a user's computer without user's permission.
Spyware programs can collect various types of personal information, such as Internet surfing habits,
and Web sites that the user has visited. Spyware programs can also interfere with the control of a
user's computer, such as installing additional software, redirecting Web browser activities, accessing
Web sites blindly, etc. Answer option C is incorrect. A honeypot is a term in computer terminology
used for a trap that is set to detect, deflect, or in some manner counteract attempts at unauthorized
use of information systems. Generally it consists of a computer, data, or a network site that appears
to be part of a network, but is actually isolated, and monitored, and which seems to contain
information or a resource of value to attackers. Answer option A is incorrect. 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 option D
is incorrect. A worm is a software program that uses computer networks and security holes to
replicate itself from one computer to another. It usually performs malicious actions, such as using
the resources of computers as well as shutting down computers.

NO.4 Which of the following storage device uses SRAM or DRAM?
A. USB flash drive
B. Solid-state drive (SSD)
C. Blu-ray Disc
D. CD drive
Answer: B
CompTIA시험문제 JK0-U31 JK0-U31교재 JK0-U31 dump
Explanation:
A solid-state drive (SSD) is a data storage device that uses solid-state memory to store persistent
data. An SSD emulates a hard disk drive interface, thus easily replacing it in most applications. It is
also known as solid-state hard disk drive. SSDs have no moving parts; hence, they are less fragile
and silent than hard disks. As there are no mechanical delays, SSDs usually enjoy low access time
and latency. An SSD using SRAM or DRAM (instead of flash memory) is often called a RAM-drive,
which should not be confused with a RAM disk. Answer option C is incorrect. Blu-ray Disc, also
known as Blu-ray or BD, is an optical disc storage medium. It is designed to supersede the standard
DVD format for storing high-definition video, PlayStation 3 games, and other data, with up to 25 GB
per single layered, and 50 GB per dual layered disc. Blu-ray Disc was developed by the Blu-ray Disc
Association, a group representing makers of consumer electronics, computer hardware, and motion
pictures. The disc has the same physical dimensions as standard DVDs and CDs. It is called Blu-ray
Disc because of the blue-violet laser which is used to read the disc. Blu-ray uses a shorter
wavelength, a 405 nm blue-violet laser, and allows for almost six times more data storage than on a
DVD. Answer option D is incorrect. CD drive is used for read/write operations on CDs. The CD drives
that are capable of performing write operations on CDs are also known as CD burners.
However, most of the CD drives on computers have read only capability. CD drives with read-only
capability are also known as CD-ROM (Compact Disc Read-Only Memory) drives.
A CD drive is installed inside the computer case and can be connected to IDE, SCSI, SATA, or firewire
interface. Answer option A is incorrect. A USB flash
drive consists of flash memory data storage device integrated with a USB (Universal Serial Bus) 1.1
or 2.0 interface.

card, MMC card, and CompactFlash (CF)?
A. E-book reader
B. Memory card reader
C. Smart card reader
D. Barcode reader
Answer: B
CompTIA최신덤프 JK0-U31자격시험 JK0-U31덤프 JK0-U31교재
Explanation:
A memory card reader is a device, typically having a USB interface, for accessing the data on a
memory card such as a CompactFlash (CF), Secure Digital (SD) or MultiMediaCard (MMC). Answer
option C is incorrect. Smart card readers are used to read smart cards. It is used as a
communications medium between the smart card and a host. Answer option D is
incorrect. A barcode reader (or barcode scanner) is an electronic device for reading printed
barcodes. Answer option A is incorrect. There is no such device as e-book reader.
NO.6 Which of the following terms refers to an anti-virus software file that is updated from time to
time to protect a computer from new viruses?
A. Definition
B. Modules
C. Service pack
D. Hotfix
Answer: A
CompTIA시험일정 JK0-U31덤프 JK0-U31 JK0-U31 dump JK0-U31 JK0-U31시험후기
Explanation:
Definition is an anti-virus software file that should be updated at regular intervals to protect a
computer from new viruses. This file is also known as virus definition file. The virus definition file
contains information
about the latest viruses, which helps identify new viruses and protect computers from them.
Answer option D is incorrect. Hotfix is a collection of files used by Microsoft for software updates
that are released between major service pack releases. A hotfix is about a problem, occurring under
specific circumstances, which cannot wait to be fixed till the next service pack release. Hotfixes are
generally
related to security problems. Hence, it is essential to fix these problems as soon as possible. Answer
option C is incorrect. A service pack is a collection of Fixes and Patches in a single product. A service
pack can be used to handle a large number of viruses and bugs or to update an operating system
with advanced and better capabilities. A service pack usually contains a number of file replacements.
Answer option B is incorrect. This term does not refer to any anti-virus software file.
Reference: "http.//en.wikipedia.org/wiki/Computer_virus"
NO.7 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. Use the Disk Management tool to move everything to the new computer.
C. Use the User State Migration tool to move the system settings and files to the new machines.
D. Copy the files and the Windows Registry to a removable media then copy it onto the new
machines.
Answer: C
CompTIA최신덤프 JK0-U31 pdf JK0-U31강좌 JK0-U31 IT자격증
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. What is User State Migration Tool (USMT)? User State Migration Tool (USMT) is used
to migrate user files and settings during large deployments of Microsoft Windows XP and Microsoft
Windows Vista operating systems. It captures desktop, and application settings, as well as user
accounts and users' files, and then migrates them to a new Windows installation. It helps
administrators to improve and simplify migration process. USMT can be used for both side-by-side
and wipe-and-load migrations. USMT component SCANSTATE.EXE
is used to collect the files and settings from the source computer and the LOADSTATE.EXE
component is used to restore the user state onto the destination computer. Answer option D is
incorrect. Moving the Windows registry will not work and could in cause major problems on the
new system. This is especially true if the new system has a more modern version of Windows.
Answer option B is incorrect. The disk management
tool is used for managing disk partitions. Answer option A is incorrect. A complete backup will likely
cause problems on the new installations. This is especially true if the new system has a more
modern version of Windows.

NO.8 Which of the following statements about a riser card is true?
A. It is used to connect a computer in a network.
B. It is used to connect extra microprocessors.
C. It provides extra memory for expansion cards.
D. It is used to extend slots for expansion cards.
Answer: D
CompTIA PDF JK0-U31자격시험 JK0-U31 dump JK0-U31 JK0-U31인증
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. What is
LPX? LPX is a motherboard form or that is used in some desktop computers. In
LPX motherboards, expansion cards are inserted into a riser card that contains several
slots. Unlike other common form ors such as AT and ATX, the expansion cards in LPX
are not vertical, but parallel to the motherboard. The LPX form or is designed for
smaller cases, and usually it is used for connecting two or three expansion cards.
