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

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.

3.Token A password is a secret word or string of characters that is used for authentication, to prove
identity, or gain access to a resource. What is authentication? Authentication is a process of
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.

NO.5 Which of the following features are related to power management? Each correct answer
represents a complete solution. Choose two.
A. Hot plugging
B. Hibernate mode
C. Standby mode
D. Safe mode
Answer: B,C
CompTIA通信 JK0-U31認定資格 JK0-U31 JK0-U31特典
Explanation:
The Hibernate mode and Standby mode are features related to power management. Hibernate
mode is a power saving feature for computers. In hibernate mode, the current state of a computer
is saved to the hard disk, and the computer shuts down. A user will have to power on the computer
to restore the previous settings. When a computer resumes from hibernate mode, it reads the
saved settings from the disk and restores the system state as it was before it entered hibernate
mode. By default, hibernate mode is disabled. If a computer is not ACPI-enabled or APM-enabled,
users will have to enter hibernate mode manually. Users cannot set the computer to automatically
hibernate after a certain time. With ACPI-enabled and APM-enabled computers, users are able to
set hibernate mode automatically. 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 A is incorrect. Hot plugging is a feature in which a device
can be installed or removed while the computer is running. Answer option D is incorrect. Safe Mode
is a Windows feature used to start a computer with basic drivers, such as mouse, keyboard, etc. It
bypasses blocking issues, such as system corruption, or installation of incompatible drivers or
system services, enabling the Administrator to resolve such issues.
NO.6 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認定証 JK0-U31模擬 JK0-U31スクール
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.
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
CompTIA関節 JK0-U31内容 JK0-U31書籍 JK0-U31 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.

C. Monitor
D. Keyboard.
Answer: A, C
CompTIA割引 JK0-U31講座 JK0-U31 JK0-U31フリーク
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.
