manual with the modem, which can be used as a reference when there is a problem with the modem. You can
also refer to the vendor’s Web site, which provides instructions to use the modem and has a reference manual to

(A) ink smears
(B) faint printouts
(C) missing characters
(D) partial characters

missing characters
partial characters
Explanation:
A defective printhead can cause a dot-matrix printer to print only partial characters, and serious defects can
prevent printing completely. Dot-matrix printers use an array of pins to strike an inked printer ribbon that
generates images on paper. The individual pins in the printhead are controlled by electromagnets, which move
the pins to form specific characters
Which type of attack redirects you to a fake Web site?
(A) land attack
(B) hyperlink spoofing
(C) ICMP packet spoofing
D) network address hijacking
(B)
hyperlink spoofing
Explanation:
Hyperlink spoofing, which is also referred to as Web spoofing, is used by an attacker to persuade the Internet
browser to connect to a fake server that appears as a valid session. The primary purpose of hyperlink spoofing is
to gain access to confidential information, such as PIN numbers, credit card numbers, and bank details of users.
The link as it appears on this page is often correct. However, the actual underlying link is usually to the spoofed
site. Beware of sites that ask for confidential information, especially if they have never done so in the past. This is
usually a sign that a hyperlink spoof has occurred
You upgrade memory on a portable computer, but the new memory is not recognized by the computer. What
should you do FIRST while troubleshooting this problem?
(A) Ensure that the system board is not faulty.
(B) Ensure that the memory is seated properly.
(C) Upgrade the system BIOS
(D) Purchase new memory
(B)
(B)
Ensure that the memory is seated properly.
Explanation:
You should first ensure that the memory is seated properly while troubleshooting the problem. If a portable
computer does not recognize newly installed memory, you should first ensure that the memory is properly seated
in the socket. You should place the module in the socket at a 45-degree angle, slide it into the socket, then press
the module down towards the system board until the side clamps latch into place. Most modern portable
computers are designed to have a separate memory compartment on the underside. If there is no separate
memory compartment, you must ensure that all connectors that were removed to replace the memory chip, such
as the touchpad connector or keyboard connector, are properly connected. If you ensure that the memory is
seated properly but the laptop still does not recognize it, you may need to flash the BIOS
You are troubleshooting a network connectivity problem on a Windows XP Professional computer. You issue the

(C) Printing of graphics has been disabled.
(D) Printing of graphics has been disabled
(A)
Printing of graphics has been disabled
Explanation:
A table of NetBIOS names resolution and registration statistics will be displayed when you issue the nbtstat -r
command. This screen displays NetBIOS connection statistics, such as the number of NetBIOS names resolved
by broadcast and the number of NetBIOS names resolved by a NetBIOS name server. This screen also displays
the NetBIOS names that have been resolved
