Question 1

A Trojan horse might allow a hacker to _____.

Accepted Answer

A Trojan horse can perform a variety of malicious activities, including seeing the contents of your screen, capturing keystrokes, and controlling your webcam.

Question 2

The process of eradicating a virus, sometimes called _____, might include deleting the virus code from files or deleting infected files.

Accepted Answer

Disinfecting is the correct term used for the process of removing a virus from infected files or systems, which might involve deleting the virus code or the infected files themselves.

Question 3

Typically, infected attachments look like _____ files, and they infect your computer when you open them.

Accepted Answer

Executable files are typically used to infect computers because they can run code when they are opened.

Question 4

_____ IP addresses is the only one that can be accessed directly from the Internet.

Accepted Answer

A router's IP address can be accessed directly from the Internet, especially if it's a public IP address. This is because routers are devices that manage traffic between your local network and the internet, making them accessible from the outside for various purposes, such as remote management or to facilitate connections to devices within the network through port forwarding. Networked printers, laptops, and PCs typically use private IP addresses within a local network and rely on the router to communicate with the internet, thus they are not directly accessible from the internet without specific configurations.

Question 5

Which of the following is the opposite of a gateway?

Accepted Answer

A gateway facilitates communication between different networks, while a firewall restricts and monitors network traffic for security purposes, making it functionally opposite in terms of access control.

Question 6

You should configure _____ to set Windows to display file extensions.

Accepted Answer

File Explorer in Windows has the option to show or hide file extensions, which can be configured in its View settings.

Question 7

A key characteristic of viruses is their ability _____.

Accepted Answer

Viruses replicate themselves on the host computer, using the host's resources to make copies of themselves.

Question 8

Which of the following files is most likely to contain a hidden virus?

Accepted Answer

Files with double extensions, particularly where a non-executable extension (like .docx) is followed by an executable one (.exe), are often used to disguise malicious software. In this case, "FinancialAid.docx.exe" is designed to appear as a Word document but is actually an executable file, which could contain a virus.

Question 9

The original wireless encryption was called _____ because it was designed to provide a level of confidentiality similar to that of a wired network.

Accepted Answer

WEP, which stands for Wired Equivalent Privacy, was the original encryption protocol designed to provide wireless networks with a level of confidentiality comparable to that of wired networks.

Question 10

If _____, Windows firewall should be on.

Accepted Answer

Windows Firewall should be on when your computer is connected to the Internet to help protect it from unauthorized access and cyber threats.

Question 11

A _____ is malicious software designed to spread from computer to computer over local area networks and the Internet.

Accepted Answer

A computer worm is specifically designed to spread itself from computer to computer over networks, unlike a virus which typically requires user action to spread.

Question 12

The most prevalent types of malicious code include all of the following, EXCEPT _____.

Accepted Answer

Spam refers to unsolicited messages, especially advertising, sent over the Internet, typically to a large number of users. It is not considered a type of malicious code like viruses, Trojan horses, or computer worms, which are designed to damage, disrupt, or gain unauthorized access to a computer system.

Question 13

The data carried by Wi-Fi signals can be encrypted with all of the following, EXCEPT _____.

Accepted Answer

WAP (Wireless Application Protocol) is not an encryption method for Wi-Fi signals. It is a technical standard for accessing information over a mobile wireless network. WEP (Wired Equivalent Privacy), WPA (Wi-Fi Protected Access), and PSK (Pre-Shared Key) are all methods used to encrypt Wi-Fi data.

Question 14

Some Trojan horses contain a virus or a worm, which can replicate and spread. Virus experts call this a(n) _____ threat because it combines more than one type of malicious code.

Accepted Answer

Blended threats combine the characteristics of viruses, worms, Trojan horses, and malicious code with server and Internet vulnerabilities to initiate, transmit, and spread an attack. This complexity allows them to propagate quickly and with significant impact.

Question 15

A _____ attack is designed to generate a lot of activity on a network by flooding it with useless traffic-enough traffic to overwhelm the network's processing capability and essentially bring all communications to a halt.

Accepted Answer

A denial of service (DoS) attack is specifically designed to overwhelm a network with excessive traffic, rendering it incapable of processing legitimate requests, thereby denying service to intended users.

Question 16

Which of the following antivirus software is included with Windows 8?

Accepted Answer

Windows Defender is the antivirus software included with Windows 8, providing built-in protection against malware.

Question 17

Modern antivirus software attempts to locate viruses by watching for a virus _____.

Accepted Answer

Modern antivirus software locates viruses by watching for their unique signatures, which are specific patterns or codes that identify the virus.

Question 18

Which of the following is a computer program that seems to perform one function while actually doing something else?

Accepted Answer

A Trojan horse is a type of malware that misleads users of its true intent. It pretends to be a legitimate program but performs malicious activities once executed.

Question 19

Which of the following virtual ports is used to accept e-mail?

Accepted Answer

Port 110 is used for POP3 (Post Office Protocol 3), which is a protocol used by email clients to retrieve emails from a mail server.

Question 20

A(n) _____ worm makes use of information on an infected computer to mail itself to everyone listed in your e-mail address book.

Accepted Answer

Mass-mailing worms specifically use the email addresses found in an infected computer's address book to propagate themselves by sending copies of the worm to those contacts.
