NO.1 Which of the following are used by FireWire 800 devices?
A. 6-pin connectors
B. 10-pin connectors
C. 9-pin connectors
D. 4-pin connectors
Answer: C

CompTIA questions   FC0-U51 practice test   FC0-U51 Real Questions
Explanation:
FireWire 800 devices use 9-pin connectors at both ends of the cable. FireWire 400 devices can also be
connected to the FireWire 800 ports and vice versa by using an appropriate adapter cable. What are
FireWire ports? Hide FireWire ports are found on high-end computers and many new media centers.
They are also called IEEE 1394 ports. FireWire ports transfer data at a rate of 400 Mbps or 800 Mbps.
They are used primarily for video transfer from digital movie cameras. Answer options D and A are
incorrect. FireWire 400 devices use 4-pin or 6-pin connectors.

A. 800x600-pixels
B. 1024x768-pixels
C. 320x200-pixels
D. 640x480-pixels
Answer: D

CompTIA Exam Cram   FC0-U51   FC0-U51
Explanation:
Video Graphic Array (VGA) monitors have a default resolution of 640x480-pixels.
This is known as standard VGA resolution. Although computers typically use this resolution by
default, you can get better resolution using a specifically designed video driver for the installed
adapter. Answer options A, C, and B are incorrect. Super VGA monitors have a default resolution of
800x600- pixels. A VGA or SVGA connector is a 15-pin, three rows, female connector, on the back of a
PC used for connecting monitors.

NO.3 You have just taken over network support for a small company. They are currently using MAC
filtering to secure their wireless network. Is this adequate or not and why or why not?
A. Yes, in fact MAC filtering is the most security you can have.
B. No, you should have WEP or WPA encryption as well.
C. Yes, MAC filtering includes encryption.
D. No, MAC filtering is not secure at all.
Answer: B

CompTIA dumps   FC0-U51 Dumps PDF   FC0-U51   FC0-U51 Test Answers
Explanation:
MAC filtering allows the possibility of someone using a packet sniffer and obtaining the MAC
addresses of the computers that connect to your network. A skilled hacker can then emulate or fake
those MAC addresses and gain access to your network. You need to also implement some form of
encryption. FactWhat is WEP? Hide Wired Equivalent Privacy (WEP) is a security protocol for wireless
local area networks (WLANs). It has two components, authentication and encryption. It provides
security, which is equivalent to wired networks, for wireless networks. WEP encrypts data on a
wireless network by using a fixed secret key. WEP incorporates a checksum in each frame to provide
protection against the attacks that attempt to reveal the key stream. FactWhat is WPA? Hide WPA
stands for Wi-Fi Protected Access. It is a wireless security standard. It provides better security than
WEP (Wired Equivalent Protection). Windows Vista supports both WPA-PSK and WPA-EAP. Each of
these is described as follows: WPA-PSK: PSK stands for Preshared key. This standard is meant for
home environment. WPA-PSK requires a user to enter an 8-character to 63-character passphrase into
a wireless client. The WPA converts the passphrase into a 256-bit key. WPA-EAP: EAP stands for
Extensible Authentication Protocol. This standard relies on a back-end server that runs Remote
Authentication Dial-In User Service for user authentication. Note: Windows Vista supports a user to
use a smart card to connect to a WPA-EAP protected network. Answer option A is incorrect. MAC
filtering by itself is not very secure. Answer option C is incorrect. MAC filtering does not include
encryption. Answer option D is incorrect. MAC filtering does provide a certain measure of security,
but by itself is usually not sufficient.

C. Honeypot
D. Worm
Answer: B

CompTIA Exam PDF   FC0-U51 Free download   FC0-U51 PDF VCE
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. Reference.

NO.6 Which of the following 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?
A. Communication and Networking Riser (CNR)
B. Audio/modem riser
C. Riser card
D. Secure Digital (SD) card
Answer: C

CompTIA Exam Dumps   FC0-U51 Latest Dumps   FC0-U51 original questions
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. Answer
option B is incorrect. The audio/modem riser (AMR), also known as an AMR slot, is an expansion slot.
It is found on the motherboards of some Pentium III, Pentium 4, and Athlon personal computers. It
was designed by Intel to interface with chipsets and provide analog functionality, such as sound cards
and modems, on an expansion card. It has two rows of 23 pins each, making a total of 46 pins.
Answer option A is incorrect. Communication and Networking Riser (CNR) is a hardware device
developed by Intel. It plugs into the motherboard and holds chips for the functioning of devices such
as modems and audio devices. It supports V.90 analog modem, multichannel audio, phone-line-based
networking, and 10/100 Ethernet-based networking. CNR also minimizes electrical noise interference
through the physical separation of noise-sensitive elements from the motherboard's communication
systems. Answer option D is incorrect. Secure Digital (SD) card is a non-volatile memory card format
used in portable devices such as mobile phones, digital cameras, and handheld computers. SD cards
are based on the older MultiMediaCard (MMC) format, but they are a little thicker than MMC cards.
Generally an SD card offers a write-protect switch on its side. SD cards generally measure 32 mm x 24
mm x 2.1 mm, but they can be as thin as 1.4 mm. The devices that have SD card slots can use the
thinner MMC cards, but the standard SD cards will not fit into the thinner MMC slots. Some SD cards
are also available with a USB connector. SD card readers allow SD cards to be accessed via many
connectivity ports such as USB, FireWire, and the common parallel port.

NO.7 Which of the following processor states does not save power?
A. C2
B. C1
C. C3
D. C0
Answer: D

CompTIA Exam PDF   FC0-U51 Exam Prep   FC0-U51
Explanation:
The C0 processor state does not save power. It is an operational state.
Answer option B is incorrect. The C1 state is a powered down state, but the processor
takes action immediately on request. The C1 state uses less power than C0 state.
Answer option A is incorrect. The C2 state is also known as Stop-Clock. It uses less power
than C1 state. In this state, the processor takes a little longer time than C1 state to come in
action on the request of applications.
Answer option C is incorrect. The C3 state is also known as the sleep mode. In this state,
the processor cache is flushed. In this state, the processor takes a few seconds to be
available for action.

NO.8 Which of the following protocols has recently been succeeded by Transport Layer Security (TLS)
protocol?
A. SNMP
B. IPX/SPX
C. HTTP
D. SSL
Answer: D

CompTIA original questions   FC0-U51   FC0-U51 Braindumps   FC0-U51 exam dumps   FC0-U51
Explanation:
The Secure Sockets Layer (SSL) is a commonly-used protocol for managing the security of a message
transmission on the Internet. SSL has recently been succeeded by Transport Layer Security (TLS),
which is based on SSL. SSL uses a program layer located between the Internet's Hypertext Transfer
Protocol (HTTP) and Transport Control Protocol (TCP) layers. SSL is included as part of both the
Microsoft and Netscape browsers and most Web server products. URLs that require an SSL
connection start with https: instead of http:. Transport Layer Security (TLS) is a cryptographic
protocol that provides security and data integrity for communications over networks such as the
Internet. Answer option B is incorrect. Internet Packet Exchange/Sequenced Packet Exchange
(IPX/SPX) is a protocol used by Novell NetWare clients to connect to NetWare server. IPX/SPX is a
routable protocol. It is supported by Microsoft operating systems. IPX/SPX can be used for both large
and small networks. The Internet does not use this protocol. Answer option A is incorrect. Simple
Network Management Protocol (SNMP) is a part of the TCP/IP protocol suite, which allows users to
manage the network. SNMP is used to keep track of what is being used on the network and how the
object is behaving. Answer option C is incorrect. Hypertext Transfer Protocol (HTTP) is a client/server
TCP/IP protocol used on the World Wide Web (WWW) to display Hypertext Markup Language (HTML)
pages. HTTP defines how messages are formatted and transmitted, and what actions Web servers
and browsers should take in response to various commands. For example, when a client application
or browser sends a request to the server using HTTP commands, the server responds with a message
containing the protocol version, success or failure code, server information, and body content,
depending on the request. HTTP uses TCP port 80 as the default port.
