CompTIA A+ Core 2 (220-1102) — Question 148

A user updates a mobile device's OS. A frequently used application becomes consistently unresponsive immediately after the device is launched. Which of the following troubleshooting steps should the user perform FIRST?

Answer options

• A. Delete the application's cache.
• B. Check for application updates.
• C. Roll back the OS update.
• D. Uninstall and reinstall the application.

Correct answer: B

Explanation

The best initial step is to check for application updates because the app may have a version that is compatible with the new OS. If the app is not updated, it may lead to performance issues. Deleting the cache, rolling back the OS update, or uninstalling the app are more drastic measures that may not resolve the underlying compatibility issue.
