Question #164
A user is unable to log in to the network. The network uses 802.1X with EAP-TLS to authenticate on the wired network. The user has been on an extended leave and has not logged in to the computer in several months.
Which of the following is causing the login issue?
- A . Expired certificate
- B . OS update failure
- C . Service not started
- D . Application crash
- E . Profile rebuild needed
Correct Answer: A
A
Explanation:
EAP-TLS is a method of authentication that uses certificates to establish a secure tunnel between the client and the server3. The certificates have a validity period and must be renewed before they expire1. If the user has been on an extended leave and has not logged in to the computer in several months, it is possible that the certificate on the client or the server has expired and needs to be renewed2. The other options are not directly related to EAP-TLS authentication or 802.1X network access.

Question #165
A user wants to acquire antivirus software for a SOHO PC. A technician recommends a licensed software product, but the user does not want to pay for a license.
Which of the following license types should the technician recommend?
- A . Corporate
- B . Open-source
- C . Personal
- D . Enterprise
Correct Answer: B
B
Explanation:

and distribute. Open-source software is usually free of charge and does not require a license to
use. Some examples of open-source antivirus software are ClamAV, Comodo, and Immunet12. The
other license types are either not free or not suitable for a SOHO PC. Corporate and enterprise
licenses are designed for large-scale organizations and networks, and they usually require a
subscription fee. Personal licenses are for individual users and may have limited features or support.

Question #166
A user’s antivirus software reports an infection that it is unable to remove.
Which of the following is the most appropriate way to remediate the issue?
- A . Disable System Restore.
- B . Utilize a Linux live disc.
- C . Quarantine the infected system.
- D . Update the anti-malware.
Correct Answer: C
C
Explanation:
Quarantining the infected system is the most appropriate way to remediate the issue of an infection that the antivirus software cannot remove. Quarantining means isolating the system from the network and other devices to prevent the infection from spreading or causing further damage. Quarantining also allows the technician to perform further analysis and removal of the infection without risking the security of other systems or data.
Some of the steps involved in quarantining an infected system are:
Disconnect the system from the internet and any local network connections, such as Wi-Fi, Ethernet, Bluetooth, or USB.
Disable any file-sharing or remote access services on the system, such as Windows File Sharing,
Remote Desktop, or TeamViewer.
Use a separate device to download and update the antivirus software and any other tools that may be needed to remove the infection, such as malware scanners, rootkit removers, or bootable rescue disks.
Transfer the updated antivirus software and tools to the infected system using a removable media, such as a CD, DVD, or USB flash drive. Scan the removable media for any infections before and after using it on the infected system.
Run the antivirus software and tools on the infected system and follow the instructions to delete or quarantine the infection. If the infection is persistent or complex, it may require booting the system from a rescue disk or using a Linux live disc to access and clean the system files.
After the infection is removed, restore the system to a previous clean state using System Restore, backup, or recovery partition. Scan the system again to ensure that it is clean and secure. Reconnect the system to the network and update the system and the antivirus software.

Question #168
A technician receives an invalid certificate error when visiting a website. Other workstations on the same local network are unable to replicate this issue.
Which of the following is most likely causing the issue?
- A . Date and time
- B . User access control
- C . UEFI boot mode
- D . Log-on times
Correct Answer: A
A
Explanation:
Date and time is the most likely cause of the issue. The date and time settings on a workstation affect the validity of the certificates used by websites to establish secure connections. If the date and time are incorrect, the workstation may not recognize the certificate as valid and display an invalid certificate error. Other workstations on the same local network may not have this issue if their date and time are correct. User access control, UEFI boot mode, and log-on times are not likely causes of the issue. User access control is a feature that prevents unauthorized changes to the system by prompting for confirmation or credentials. UEFI boot mode is a firmware interface that controls the boot process of the workstation. Log-on times are settings that restrict when a user can log in to the workstation. None of these factors affect the validity of the certificates used by websites.

Question #170
A user is unable to access several documents saved on a work PC. A technician discovers the files were corrupted and must change several system settings within Registry Editor to correct the issue.
Which of the following should the technician do before modifying the registry keys?
- A . Update the anti-malware software.
- B . Create a restore point.
- C . Run the PC in sate mode.
- D . Roll back the system updates.
Correct Answer: B
B

Creating a restore point before modifying the registry keys allows the technician to revert the system back to a previous state if something goes wrong or causes instability2. Updating the anti-malware software, running the PC in safe mode, and rolling back the system updates are not necessary steps before modifying the registry keys.
