CompTIA JK0-U31 短期 JK0-U31 参考書
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.

verifying the identity of a person, network host, or system process. The authentication process
compares the provided credentials with the credentials stored in the database of an authentication
server. What is biometrics?Biometrics is a method of authentication that uses physical
characteristics, such as fingerprints, scars, retinal patterns, and other forms of biophysical qualities
to identify a user. Nowadays, the usage of biometric devices such as hand scanners and retinal
scanners is becoming more common in the business environment. A token may be a physical device
or software token that an authorized user of computer services is given to ease authentication.
Answer option B is incorrect. Encryption can be used to accomplish security and not authentication.
NO.3 Which of the following is an international standard for energy efficient consumer products?
A. Energy Star rating
B. Standby mode
C. Trusted Computer System Evaluation Criteria (TCSEC)
D. Advanced Configuration and Power Interface (ACPI)
Answer: A
CompTIA JK0-U31 受験記 JK0-U31 赤本 JK0-U31
Explanation:
Energy Star rating is an international standard for energy efficient consumer products. The Energy
Star rating is an international standard for energy efficient consumer products. Devices carrying
the Energy Star logo are products, such as computer devices, peripherals, kitchen appliances, etc.
These products generally use 20% to 30% lesser energy than required by the federal standards. The
Energy Star program was created by the 'United
States Environmental Protection Agency' (US EPA) as an attempt to reduce energy consumption and
greenhouse gas emission by power plants. The program has helped in spreading the use of LED
traffic lights, efficient fluorescent lighting, and power management systems for office equipments.
Answer option C is incorrect. Trusted Computer System Evaluation Criteria (TCSEC), frequently
referred to as the Orange Book, is the centerpiece of the DoD Rainbow Series publications. It is a
United States Government Department of Defense (DoD) standard that sets basic requirements for
assessing the effectiveness of computer security controls built into a computer system. TCSEC was
used to evaluate, classify and select computer systems being considered for the processing, storage
and retrieval of sensitive or classified information.
It was replaced with the development of the Common Criteria international standard originally
published in 2005. Answer option B is incorrect. The standby mode is a power saving feature for
computers. In this mode, a computer does not shut down completely. The computer goes to low
power state and, as a result, it consumes less power. When the computer resumes from the standby
mode, full power is restored to its devices. During the standby mode, if the power supply is
disconnected or interrupted, data might be lost. The standby mode is available automatically on
ACPI-enabled or APM-enabled computers. Users do not need to enable this mode manually. This
mode is not available in non-ACPI and non-APM based computers. Answer option D is incorrect. The
Advanced Configuration and Power Interface (ACPI) is a power- management specification
developed by Intel, Microsoft, and Toshiba. It enables an operating system to control the amount of
power supplied to each device attached to a computer by turning off peripheral devices when they
are not in use. It defines power management on a wide range of mobile,
desktop, and server computers and peripherals. It also enables manuurers to produce computers
that automatically power up as soon as a user touches the keyboard.

D. DB-9
Answer:
A, C
Explanation:
The PS/ 2 and USB ports on a computer are used to connect a keyboard. What is USB? Universal
Serial Bus (USB) is a high speed bus standard developed by Compaq, IBM, DEC, Intel, Microsoft, NEC,
and Northern Telecom. It provides the Plug and Play capability of Windows to external hardware
devices. USB supports hot plugging, which means that a USB device can be installed or removed
while the computer is running. A single USB port can be used to connect up to 127 peripheral
devices, such as CD-ROM drives, tape drives, keyboards, scanners etc. USB 1.1 has a maximum data
transfer rate of 12 Mbps, whereas USB 2.0 has a maximum data transfer rate of 480 Mbps. USB 2.0
is fully backward compatible with USB 1.1. Answer options D and B are incorrect. The DB-9 and
DB-25 port types on the computer are used as serial ports. A DB-9 male type port has 9 pins,
whereas a DB-25 male type port has 25 pins. What is a serial port? Serial port is the primary means
for connecting modems and mouse to a computer. There are two types of serial port connectors,
9-pin and 25-pin. The word serial refers to the data is sent in series, one bit at a time, over a single
wire. This design is significantly slower than sending 8 bits at a time via a parallel channel, but serial
signals can travel much farther without degradation.

Answer: C
CompTIA 関節 JK0-U31 教育 JK0-U31 認定 JK0-U31 過去
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.
