The technician should instruct the user to clear the browser cache and contact the bank (option A).

This error indicates that the website the user is visiting is not the correct website and is likely due to a cached version of the website being stored in the user's browser. Clearing the browser cache should remove any stored versions of the website and allow the user to access the correct website.

The user should also contact the bank to confirm that they are visiting the correct website and to report the error.

The rollback plan should be updated before requesting approval again. A rollback plan is a plan for undoing a change if it causes problems, and it is an important part of any change management process. If the change advisory board did not approve the requested change due to the lack of alternative actions if implementation failed, then updating the rollback plan would be the best way to address this concern.

The technician should have connected a proper ESD strap to prevent damage to the motherboard.ESD (electrostatic discharge) can cause damage to electronic components, and an ESD strap helps to prevent this by grounding the technician and preventing the buildup of static electricity. Removing all jewelry is also a good practice, but it is not the most likely solution to this problem.

Ransomware is malicious software that encrypts files on a computer, making them inaccessible until a ransom is paid. In this case, the user was able to access the files before without issue, and no changes have been made within the company, so it is likely that the computer was infected with ransomware.

The best ways to limit the bank’s risk are to enable multifactor authentication for each support account and enforce account lockouts after five bad password attempts. Multifactor authentication adds an extra layer of security to the login process, making it more difficult for attackers to gain access to systems. Account lockouts after five bad password attempts can help to prevent brute force attacks by locking out accounts after a certain number of failed login attempts.

This is the most effective way to selectively prevent programs from loading on a Windows 10 machine. The Startup tab can be accessed by opening Task Manager and then selecting the Startup tab. From there, the technician can methodically disable items that are currently listed as enabled, reboot the machine, and check for issue resolution at each startup. If the issue persists, the technician can then move on to disabling the next item on the list.

Before removing a Trojan virus from a workstation, a technician should disable System Restore. System Restore is a feature that allows users to restore their system to a previous state in case of problems or errors. However, System Restore can also restore infected files or registry entries that were removed by antivirus software or manual actions. By disabling System Restore, a technician can ensure that the Trojan virus is completely removed and does not reappear after a system restore operation. Scheduling a malware scan may help detect and remove some malware but may not be effective against all types of Trojan viruses. Educating the end user may help prevent future infections but does not address the current issue of removing the Trojan virus. Running Windows Update may help patch some security vulnerabilities but does not guarantee that the Trojan virus will be removed.

Installing applications directly from a vendor's website can be risky, as the application may be malicious or fraudulent. Uninstalling the application can help mitigate the issue by removing the source of the problem
