A technician suspects a rootkit has been installed and needs to be removed.
Which of the following would BEST resolve the issue?
- A . Application updates
- B . Anti-malware software
- C . OS reinstallation
- D . File restore
C
Explanation:
If a rootkit has caused a deep infection, then the only way to remove the rootkit is to reinstall the operating system. This is because rootkits are designed to be difficult to detect and remove, and they can hide in the operating system’s kernel, making it difficult to remove them without reinstalling the operating system https://www.minitool.com/backup-tips/how-to-get-rid-of-rootkit-windows-10.html

A technician sees a file that is requesting payment to a cryptocurrency address.
Which of the following should the technician do first?
- A . Quarantine the computer.
- B . Disable System Restore.
- C . Update the antivirus software definitions.
- D . Boot to safe mode.
A
Explanation:
Quarantining the computer means isolating it from the network and other devices to prevent the spread of malware or ransomware. Ransomware is a type of malware that encrypts the files on a computer and demands payment (usually in cryptocurrency) to restore them. If a technician sees a file that is requesting payment to a cryptocurrency address, it is likely that the computer has been infected by ransomware. Quarantining the computer should be the first step to contain the infection and prevent further damage. Disabling System Restore, updating the antivirus software definitions, and booting to safe mode are not steps that should be done before quarantining the computer.

- A . AUP
- B . EULA
- C . EOL
- D . UAC
C
Explanation:
EOL (end-of-life) is a term that indicates a vendor no longer supports a product. It means that the product will no longer be sold, updated or patched by the vendor, and that the users should migrate to a newer version or alternative product. AUP (acceptable use policy), EULA (end-user license agreement) and UAC (user account control) are not terms that indicate a vendor no longer supports a product.

A technician is working to resolve a Wi-Fi network issue at a doctor’s office that is located next to an apartment complex. The technician discovers that employees and patients are not the only people on the network.
Which of the following should the technician do to BEST minimize this issue?
- A . Disable unused ports.
- B . Remove the guest network
- C . Add a password to the guest network
- D . Change the network channel.
C
Explanation:
The question suggests that unauthorized users from the neighboring apartment complex may be accessing the network. By adding a password to the guest network, the technician can restrict access to only those who have been given the password. This should help to minimize unauthorized access from individuals in the apartment complex.
While changing the network channel might help with interference issues (common in environments with many Wi-Fi networks), it wouldn’t necessarily help prevent unauthorized access. Disabling unused ports and removing the guest network can be too restrictive and might hinder legitimate usage for guests or certain devices.

Which of the following threats will the use of a privacy screen on a computer help prevent?
- A . Impersonation
- B . Shoulder surfing
- C . Whaling
- D . Tailgating
B
Explanation:
Shoulder surfing is a threat that involves someone looking over another person’s shoulder to observe their screen, keyboard, or other sensitive information. Shoulder surfing can be used to steal passwords, personal identification numbers (PINs), credit card numbers, or other confidential data. The use of a privacy screen on a computer can help prevent shoulder surfing by limiting the viewing angle of the screen and making it harder for someone to see the screen from the side or behind. Impersonation, whaling, and tailgating are not threats that can be prevented by using a privacy screen on a computer.
