Answer: C
CompTIA FC0-U51 exam dumps FC0-U51 demo FC0-U51
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.

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.

Explanation:
The WUXGA video technology supports the maximum resolution of 1920 x 1200. Where
1920 refers to horizontal pixels, and 1200 refers to vertical pixels. Answer option A is incorrect. The
QXGA video technology supports the maximum resolution of 2048 x 1536. Answer option D is
incorrect. UXGA stands for Ultra eXtended Graphics Array. It is a display standard that refers to video
adapters. This display standard is capable of displaying the resolution of 1600 x 1200 pixels. A UXGA
display provides four times more pixels than an 800 x 600 display. Answer option C is incorrect. The
WQUXGA video technology supports the maximum resolution of 3840 x 2400.

CompTIA Real Questions FC0-U51 certification training FC0-U51 dumps torrent FC0-U51 Exam Cram 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.

B. C1
C. C3
D. C0
Answer: D
CompTIA Exam Dumps FC0-U51 Test Answers FC0-U51 Bootcamp FC0-U51 questions FC0-U51 Exam Dumps
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.7 Which of the following indicates the subjects that can use them?
A. Access control list
B. Audit policy
C. Intrusion detection system
D. Single sign-on
Answer: A
CompTIA Test Answers FC0-U51 VCE Dumps FC0-U51 VCE Dumps FC0-U51 original questions FC0-U51 Exam Prep
Explanation:
Access control list indicates what subjects can use them. Access Control List (ACL) is the most
commonly used object in Cisco IOS. It filters packets or network traffic by controlling whether routed
packets are forwarded or blocked at the router's interfaces. According to the criteria specified within
the access lists, router determines whether the packets to be forwarded or dropped. Access control
list criteria could be the source or destination address of the traffic or other information. The types of
Cisco ACLs are Standard IP, Extended IP, IPX, Appletalk, etc. Answer option B is incorrect. Audit policy
defines the type of security events that will be logged for the servers of a domain or for an individual
computer. It does not indicate what subjects can use them. Answer option C is incorrect. An Intrusion
detection system (IDS) is software and/or hardware designed to detect unwanted attempts at
accessing, manipulating, and/or disabling of computer systems, mainly through a network, such as
the Internet. These attempts may take the form of attacks, as examples, by crackers, malware and/or
disgruntled employees. An IDS cannot directly detect attacks within properly encrypted traffic. An
intrusion detection system is used to detect several types of malicious behaviors that can
compromise the security and trust of a computer system. This includes network attacks against
vulnerable services, data driven attacks on applications, host based attacks such as privilege
escalation, unauthorized logins and access to sensitive files, and malware (viruses, trojan horses, and
worms). Answer option D is incorrect. Single sign-on is a process that enables a user with a domain
account to log on to a network once, using a password or smart card, and to gain access to multiple
computers in the domain without being prompted to log in again.

D. Worm
Answer: B
CompTIA Free download FC0-U51 practice test FC0-U51 FC0-U51 VCE Dumps FC0-U51 Real Questions
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.
