CompTIA A+ Core 2 (220-1102) — Question 504

A smartphone user is experiencing issues getting an application to launch. When the user taps on the application name, nothing happens. The user recently updated the smartphone's OS. Which of the following steps should the technician take next to troubleshoot the issue?

Answer options

• A. Roll back the OS update
• B. Uninstall the application
• C. Restart the smartphone
• D. Check for application updates

Correct answer: C

Explanation

Restarting the smartphone (C) can resolve temporary software glitches that may have occurred after the OS update. Rolling back the OS update (A) is more drastic and typically not the first step. Uninstalling the application (B) is unnecessary if the issue could be resolved by a simple restart. Checking for application updates (D) is also a valid step, but it’s more effective to reboot first to see if it resolves the issue.
