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.
QUESTION NO: 8
Which of the following transmits all ATSC HDTV standards and supports 8-channel digital audio?
A. DVI
B. S-Video
C. SVGA
D. HDMI
Correct Answer: D
Explanation
Explanation/Reference:
Explanation:
HDMI stands for High-Definition Multimedia Interface. It is a standard, uncompressed, and all-digital audio/
video interface. HDMI is capable of delivering the highest quality digital video and multichannel digital
audio on a single cable. It provides an interface between any audio/video sources, such as a DVD player
or a computer and a digital television (DTV) or video monitor. HDMI transmits all ATSC HDTV standards
and supports 8-channel digital audio, with extra bandwidth to accommodate future enhancements. HDMI
has two types of connectors. Type A and Type B. Type A and Type B connectors use 19 pins and 29 pins,
respectively. The Type B connector is designed for very high- resolution displays that are expected in near
future.
Answer option B is incorrect. S-Video, also known as Y/C video, stands for Super-Video. It is a technology
for video transmission. Using this technology, the video is transmitted into two separate signals. One is
used for color, and the other for brightness. Sometimes S-Video signals are considered as a type of
component video signal. However, its quality is inferior to other complex component video schemes such
as RGB. This technology produces sharper images than those produced by composite video, which
carries the entire set of signals in a single line. For using SVideo, the device sending the signal must
support S-Video output and the device receiving the signal needs to have an S-Video input jack.
Answer option A is incorrect. DVI stands for Digital Visual Interface. It is a standard for high speed, high
resolution digital display invented by
Digital Display Working Group (DDWG). DVI accommodates analog and digital interfaces with a single
connector. New video cards have DVI as well as VGA ports built into them. Most of LCD monitors come
with a 15-pin VGA connection cable, even if they are capable of handling digital signals coming from DVI
connections. However, some monitors come with both types of cables. DVI has three main categories of
connectors. They are. DVI-A, DVI-D, and DVI-I. DVI-A is an analog- only connector, DVI-D is a digital-only
connector, and DVI-I is an analog/digital connector. DVI-D and DVI-I connectors are of two types. single
link and dual link. DVI supports UXGA and HDTV with a single set of links.
Higher resolutions such as 1920 x 1080, 2048 x 1536, or more can be supported with dual links. Answer
option C is incorrect. A VGA or SVGA connector is a 15-pin, three rows, female connector, on the back of
a PC used for connecting monitors. Reference. “http.//en.wikipedia.org/wiki/High-
Definition_Multimedia_Interface”

QUESTION NO: 6
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
Correct Answer: BC
Explanation
Explanation/Reference:
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.
QUESTION NO: 11
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
Correct Answer: D
Explanation
Explanation/Reference:
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. Reference.
