Question 1

Which of the following does not destroy the data on a hard drive?

Accepted Answer

Formatting a hard drive typically does not destroy the data completely. It removes the address tables, making the data invisible to the system, but the data itself remains until it is overwritten. Disk wiping, data destruction, and degaussing are all methods specifically designed to completely erase or destroy data on a hard drive.

Question 2

Which of the following can permanently remove data from a drive?

Accepted Answer

Disk wiping and degaussing are methods that can permanently remove data from a drive. Disk wiping involves overwriting the existing data with random data, often multiple times, to prevent data recovery. Degaussing uses a strong magnetic field to disrupt the magnetic domains on the drive, effectively destroying the data.

Question 3

Which of the following statements best describes hidden files?

Accepted Answer

Hidden files are those that the operating system is configured to not display by default, often to prevent accidental modification or deletion by users.

Question 4

Which of the following statements about formatting is not true?

Accepted Answer

Formatting a disk does not permanently delete the files; it primarily removes the address tables, making the data inaccessible to the operating system. However, with specialized software, it's often possible to recover data from a formatted disk.

Question 5

Which of the following statements best describes metadata?

Accepted Answer

Metadata is essentially data about data, which in the context of a file, includes details that describe or identify the file, such as its creation date, author, file size, and format. This information helps in managing and organizing data effectively.

Question 6

Which of the following statements best describes a cookie?

Accepted Answer

Cookies are files created by websites you visit that store browsing information, such as your site preferences or profile information.

Question 7

Which of the following is a temporary storage for web documents such as HTML pages and downloads?

Accepted Answer

A web cache temporarily stores web documents, such as HTML pages and images, to reduce server lag and improve load times for users.

Question 8

Which of the following is an example of a browser-based data?

Accepted Answer

All the options listed (Cookies, Form history, Search bar history) are examples of browser-based data, as they are stored or managed within a web browser.

Question 9

Layered defense for securing facilities is both physical and __________.

Accepted Answer

Layered defense includes psychological elements to deter potential intruders by creating a perception of increased risk or difficulty in breaching the facility.

Question 10

Class C fire extinguishers are best suited for which of the following fires?

Accepted Answer

Class C fire extinguishers are designed for electrical fires, such as those involving computer equipment, making them the best choice for such scenarios.

Question 11

Class A fire extinguishers are best suited for which of the following fires?

Accepted Answer

The answer of Class A fire extinguishers are best suited...

Question 12

The design of a secure site starts with the __________ of the site.

Accepted Answer

The answer of The design of a secure site starts...

Question 13

Which of the following is the first line of defense for fires?

Accepted Answer

Fire prevention controls are the first line of defense against fires, aiming to prevent fires from starting in the first place.

Question 14

Which of the following is an example of a fire prevention control?

Accepted Answer

Adhering to building and construction codes is an example of a fire prevention control because it involves measures and standards designed to prevent fires from occurring in the first place, by ensuring that buildings are constructed and maintained in a way that minimizes the risk of fire.

Question 15

Fences used in perimeter security should be at least how many feet in height?

Accepted Answer

Fences used in perimeter security are typically recommended to be at least 8 feet in height to deter unauthorized access effectively.

Question 16

Which of the following refers to a prolonged increase in voltage (minutes or hours)?

Accepted Answer

A power surge refers to a prolonged increase in voltage over a longer period, such as minutes or hours, which can potentially damage electrical devices connected to the power source. Power spikes, sags, and faults are different types of power disturbances that do not describe a prolonged increase in voltage.

Question 17

Which of the following refers to a prolonged period of power loss (hours or days)?

Accepted Answer

A blackout refers to a complete loss of power in a large area for a prolonged period, which can last from hours to days.

Question 18

Which of the following is defined by NIST as "the result of actions taken to ensure that media cannot be reused as originally intended and that information is virtually impossible to recover or prohibitively expensive."

Accepted Answer

Data destruction is defined by NIST as the process of ensuring that media cannot be reused as originally intended and that information is virtually impossible to recover or prohibitively expensive. This involves actions that remove or destroy the data stored on a storage medium, making data recovery infeasible.

Question 19

Which of the following refers to a technique that uses the encryption of target data by enabling sanitization of the target data's encryption key?

Accepted Answer

Cryptographic erase refers to the process where the encryption key used to encrypt data is itself deleted or made inaccessible, effectively rendering the encrypted data irrecoverable. This technique leverages encryption to sanitize data by removing the key, rather than directly erasing the data itself.
