Question 1

Active scripts are used so that web pages stay static and do not change except for the data entered into textboxes or customer-driven scripts.

Accepted Answer

Active scripts are used to create dynamic or interactive web pages that respond to user actions such as clicking a button or hovering over an element. They allow web pages to change dynamically, even without user input.

Question 2

PGP or S/MIME is used to protect email.

Accepted Answer

PGP (Pretty Good Privacy) and S/MIME (Secure/Multipurpose Internet Mail Extensions) are both encryption methods used to protect the content of email messages. They both provide end-to-end encryption, which means that only the intended recipient can decrypt and read the message. Therefore, the statement is true.

Question 3

When WEP is configured on the access point, all wireless clients must use WEP.

Accepted Answer

When WEP is configured on the access point, all wireless clients must use WEP. This is because WEP is a security protocol that encrypts wireless signals, and in order for the access point and clients to communicate securely, they must use the same encryption method. If some clients use a different encryption method, they may not be able to connect to the network or may compromise the security of the network.

Question 4

A new file is created and stored in an encrypted folder. The file must be manually encrypted because it was added after the folder was encrypted.

Accepted Answer

When a file is added to an encrypted folder, it inherits the folder's encryption properties automatically, so manual encryption of the new file is not necessary.

Question 5

An email that comes from what appears to be your own bank, but actually is not, is an example of spyware.

Accepted Answer

An email that appears to come from a bank but actually does not is an example of phishing, not spyware. Spyware refers to malicious software installed on a computer without the user's knowledge, with the intention of gathering private information or controlling the computer's operations.

Question 6

SSID broadcasting is when an access point sends out its WEP key to all wireless clients through the air. Those clients attached to the access point are allowed to transmit data.

Accepted Answer

SSID broadcasting is the act of the access point announcing its presence and availability to nearby devices, it does not involve sending out the WEP key to clients. Clients who have the correct WEP key can still connect to the access point without the SSID being broadcasted.

Question 7

WEP is a type of wireless authentication technique.

Accepted Answer

WEP (Wired Equivalent Privacy) is a security protocol for wireless networks, not an authentication technique. It is used to encrypt data transmitted over the network.

Question 8

40-bit WEP and 64-bit WEP are the same thing.

Accepted Answer

40-bit WEP and 64-bit WEP refer to the same encryption level, where the actual encryption key is 40 bits long, and an additional 24-bit initialization vector is used to make up the 64 bits.

Question 9

Phishing is controlled by using S/MIME.

Accepted Answer

S/MIME (Secure/Multipurpose Internet Mail Extensions) is a protocol used for securing emails, but it is not specifically designed to counter phishing attacks. Other measures like spam filters, two-factor authentication, and user education are used to prevent phishing.

Question 10

Mobile devices do not need antivirus software.

Accepted Answer

Mobile devices, like computers, can be vulnerable to malware and viruses. It is important to install antivirus software on your mobile device to protect against these threats.

Question 11

A firewall cannot protect a wireless network.

Accepted Answer

A firewall can protect a wireless network by controlling and monitoring incoming and outgoing network traffic. However, additional security measures such as encryption and network segmentation may be necessary for complete protection.

Question 12

Grayware is a generic term for application or files that affect the computerʹs performance and cause it to act unusual.

Accepted Answer

Grayware is a legitimate software or file that may have undesirable effects on the computer system, such as slowing down the performance or displaying annoying pop-up ads. It's not as harmful as malware, but it's still considered potentially unwanted.

Question 13

When you have a personal incident of child exploitation, you should report it to the FBI.

Accepted Answer

The FBI has jurisdiction over federal crimes, including child exploitation. Reporting to them can help begin an investigation and potentially bring justice for the victims.

Question 14

Adware would show up as one or more pop-ups on a computer.

Accepted Answer

Adware typically displays advertisements in the form of pop-ups on a computer.

Question 15

A SPAN is a special type of security network.

Accepted Answer

A SPAN (Switched Port Analyzer) is a feature that allows the mirroring of network packets from one switch port to another for monitoring and analysis purposes, not a type of security network.

Question 16

When you have a personal incident of phishing, you should report it to the FBI.

Accepted Answer

Phishing incidents are typically reported to the Federal Trade Commission (FTC) or local authorities, not directly to the FBI, unless it involves significant financial loss or is part of a larger criminal investigation.

Question 17

A program that you have never used is trying to access your computer and the Windows firewall notices it. An alert comes up, and you use the Keep Blocking This Program option so that the program is effectively blocked.

Accepted Answer

This is a common scenario where the Windows firewall alerts the user about an unknown program trying to access the computer. By using the "Keep Blocking This Program" option, the user can effectively block the program from accessing the computer.

Question 18

802.1x security standards can be applied to wireless networks.

Accepted Answer

802.1x security standards are commonly used to provide secure access control to wireless networks.

Question 19

TKIP and AES improve WEP encryption.

Accepted Answer

TKIP (Temporal Key Integrity Protocol) and AES (Advanced Encryption Standard) were introduced to address the weaknesses of WEP (Wired Equivalent Privacy) encryption. TKIP uses a message integrity code and a per-packet key, while AES uses a stronger encryption algorithm, making them both more secure than WEP. Therefore, TKIP and AES are improvements to WEP encryption.

Question 20

A cookie is a special program written to collect information and store it on the hard drive.

Accepted Answer

Cookies are indeed small text files that are stored on a user's computer by websites they visit. They can be used to collect and store information such as user preferences, login credentials, and browsing history.
