A cyber technician successfully captures the user profile for a computer that is demonstrating performance issues. The technician moves this profile onto a new computer for the employee’s use. What is this called?

Answer 11

Reimaging the device

Question 12

A cyber architect troubleshoots a computer with the message that reflects “OS not found.” What recovery mode command prompts repair of the master boot record (MBR)?

Answer 12

bootrec/fixmbr

Question 13

A software engineer is reviewing a help ticket where an employee can not access their account due to corrupted files but has to regain the data. What method allows the engineer to take uncorrupted data and place it in a new account for the employee?

Answer 13

Rebuild Windows profile; Operating systems allow users to rebuild a profile by taking uncorrupted data and adding it to the functional profile.

Question 14

A software engineer is drafting a memo that focuses on anomalous system behavior regarding system security. What is a symptom of malware introduction to a computer’s file system?

Answer 14

Symptoms of security issues in the file system include files being renamed or deleted.

Question 15

A cyber consultant troubleshoots a computer with anomalous errors and believes the issues originated from malware infection. What is a symptom of security issues associated with malware?

Answer 15

Symptoms of security issues in the file system include altered system files or personal files with date stamps and file sizes different from known-good versions.

Question 16

A technician is reviewing open-source literature on redirection. What type of malware exploits a target page to capture authentication details?

Answer 16

Spyware; Redirection is where the user tries to open one page but gets sent to another. Often this may imitate the target page. Spyware may exploit it to capture authentication details.

Question 17

A software engineer is having issues with one of the company laptops and believes it may have malware. What is a symptom that the device may have been affected by malware?

Answer 17

When the computer is slow or “behaving oddly,” one of the things that the engineer should suspect is that malware has infected the device. A symptom can include the host being unable to access the network or internet.

Question 18

A cyber associate reviews the company policy on troubleshooting desktop symptoms of malware infection. What is a key indicator that malware infection has occurred in security-related applications?

Answer 18

OS Update Failure; One of the key indicators of malware infection is that security-related applications, such as antivirus, firewall, and Windows Update, stop working. Additionally, operating system (OS) updates may fail, leaving the device in a compromised status.

Question 19

A software engineer is drafting a memo that focuses on anomalous system behavior regarding system security. What is a symptom of malware introduction to a computer’s file system?

Answer 19

File names of saved work have changed.
