CompTIA体験 JK0-U31受験記 JK0-U31難易度 JK0-U31ガイド
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.

D. Keyboard.
Answer: A, C
CompTIA過去 JK0-U31日記 JK0-U31 JK0-U31合格点 JK0-U31 PDF
Explanation:
A computer monitor and SMPS are at high voltage. Therefore, these devices can be fatal. They
usually have large amount of electric charge stored in capacitors for days after they have been
unplugged from power source. What is SMPS? Switch Mode Power Supply (SMPS) is a device that
converts raw input power to controlled voltage and current for the operation of electronic
equipment. SMPS uses switches for high efficiency. Answer options D and B are incorrect.
Keyboards and floppy drives do not store electric charge. Therefore, they cannot cause lethal
electric shocks.
NO.5 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
CompTIA JK0-U31認定資格 JK0-U31 JK0-U31練習
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.

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.

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.
