9. A technician is updating a virtual desktop. The technician discovers that a single update interferes with a business-critical application. The technician reviews the vendor website and learns that the application is EOL and will not receive any further development. Which of the following should the technician do to restore the functionality with minimum downtime?
Answer: B
Uninstall and block the patch.
To restore functionality with minimum downtime, the technician should uninstall the problematic update and block it to prevent future application issues. This approach directly addresses the interference caused by the update while allowing the business-critical application to continue functioning.
A) Perform a System Restore.
While performing a System Restore could revert the system to a previous state where the application functioned correctly, it may also undo other important updates or changes made after the restoration point. This process can lead to longer downtime as the technician would need to reapply updates and configurations.
B) Uninstall and block the patch.
This option is effective because it directly targets the specific update interfering with the application, ensuring that the application can run without issues. By blocking the patch, the technician prevents the same problem from occurring in the future, thus minimizing downtime.
C) Upgrade the application.
Upgrading the application is not a viable option in this scenario since the application is End of Life (EOL) and will not receive further development. Attempting to upgrade it may not only be impossible but could also lead to additional complications and longer downtime without guaranteeing a solution.
D) Change the underlying hypervisor.
Changing the underlying hypervisor is a significant and complex task that would likely cause extensive downtime and may not resolve the specific issue with the application affected by the update. This option is not practical given the technician's goal of minimizing downtime and quickly restoring functionality.
Conclusion
Uninstalling and blocking the patch is the most efficient solution to restore the business-critical application while minimizing downtime. The other options either do not directly address the issue, may lead to greater complications, or are not feasible due to the application's EOL status. Thus, option B stands out as the definitive correct choice.
