An administrator responded to an incident where an employee copied financial data to a portable hard drive and then left the company with the data. The administrator documentedthe movement of the evidence. Which of the following concepts did the administrator demonstrate?

1. A. Preserving chain of custody
2. B. Implementing data protection policies
3. C. Informing law enforcement
4. D. Creating a summary of the incident

Correct Answer: A
Preserving chain of custody is a concept that refers to the documentation and tracking of who handled, accessed, modified, or transferred a piece of evidence, when, where, why, and how. Preserving chain of custody can help establish the authenticity, integrity, and reliability of the evidence, as well as prevent tampering, alteration, or loss of the evidence. An administrator who documented the movement of the evidence demonstrated the concept of preserving chain of custody. Implementing data protection policies, informing law enforcement, and creating a summary of the incident are not concepts that describe the action of documenting the movement of the evidence.

A technician is troubleshooting an issue with a computer that contains sensitive information. The technician determines the computer needs to be taken off site for repair. Which of the following should the technician do NEXT?
Solution:
The next step that the technician should do before taking the computer off site for repair is to get authorization from the manager. Getting authorization from the manager is important because it ensures that the technician has permission and approval to remove the computer from the premises and perform the repair work off site. Getting authorization from the manager can also help document and communicate the reason and duration of the repair and avoid any misunderstanding or conflict with the user or the organization. Removing the HDD and then sending the computer for repair may not be feasible or necessary if the issue is not related to the HDD or if the HDD contains essential data or software for the repair. Checking corporate policies for guidance may be a good step but it does not replace getting authorization from the manager who is responsible for the computer and its data. Deleting the sensitive information before the computer leaves the building may not be possible or advisable if the issue prevents access to the data or if the data is needed for troubleshooting or recovery purposes.

A user installed a new computer game. Upon starting the game, the user notices the frame rates are low. Which of the following should the user upgrade to resolve the issue?

1. A. Hard drive
2. B. Graphics card
3. C. Random-access memory
4. D. Monitor

Correct Answer: B
A graphics card, also known as a video card or a GPU (graphics processing unit), is a component that can affect the performance of a computer game. A graphics card is responsible for rendering and displaying graphics on the screen, such as images, animations, and effects. A computer game may require a high level of graphics processing power to run smoothly and achieve high frame rates, which are the number of frames per second (FPS) that the game can display. Upgrading to a better graphics card can improve the performance of a computer game by increasing its graphics quality and frame rates. Hard drive, random-access memory, and monitor are not components that can directly
improve the performance of a computer game.

A user's smartphone data usage is well above average. The user suspects an installed application is transmitting data in the background. The user would like to be alerted when an application attempts to communicate with the internet. Which of the following BEST addresses the user's concern?

1. A. Operating system updates
2. B. Remote wipe
3. C. Antivirus
4. D. Firewall

Correct Answer: D
A firewall is a security system that monitors and controls incoming and outgoing network traffic based on predetermined security rules. In this scenario, the user is concerned about an installed application transmitting data in the background, so a firewall would be the best solution to address their concern. By installing and configuring a firewall, the user can block unauthorized connections to and from the device, and receive alerts whenever an application tries to access the internet.
