20+ practice questions focused on Mobile OS and App Troubleshooting — one of the most tested topics on the CompTIA A+ Core 2 220-1202 exam. Each question includes a detailed explanation so you learn why the right answer is correct.
Start Mobile OS and App Troubleshooting PracticeA technician is investigating a security incident where a user's corporate email account was accessed from an unknown device. The user's iPhone shows no suspicious apps, and the password was recently changed. Which of the following is the MOST likely cause?
Explanation: Option B is correct because OAuth tokens or app-specific passwords bypass the need for the primary password, allowing persistent access even after a password change. Since the user's iPhone shows no suspicious apps and the password was recently changed, a stolen token is the most plausible vector for unauthorized email access via Exchange ActiveSync or modern authentication.
A user reports that their Android phone's battery drains rapidly after a recent app update. They have already tried restarting the device. Which of the following should a technician recommend FIRST to diagnose the issue?
Explanation: Option B is correct because the first step in diagnosing rapid battery drain after an app update is to use the built-in battery usage tool in Android Settings. This tool provides a per-app breakdown of power consumption, allowing the technician to identify which specific app is consuming excessive energy without making invasive changes. Restarting the device already failed to resolve the issue, so checking battery stats is the logical next step before any destructive or restrictive actions.
A technician is configuring a kiosk mode on a company-owned Android tablet for customer use. After enabling the dedicated device management app, the tablet still allows users to exit the kiosk app by pressing the home button. Which setting did the technician MOST likely overlook?
Explanation: The technician enabled the dedicated device management app but did not activate Android's 'Lock task mode' (or 'Pin app' feature). This mode is required to pin the kiosk app to the foreground and block system navigation keys (Home, Recent Apps), preventing users from exiting the app. Without it, the Home button remains functional, allowing escape from the kiosk environment.
A user reports that their Android phone's Bluetooth keeps disconnecting from their car's hands-free system. The technician has already cleared the Bluetooth cache and re-paired the devices. What should the technician do NEXT?
Explanation: Option B is correct because after basic troubleshooting (cache clear and re-pair) fails, the next logical step is to check for firmware updates on the car's infotainment system. Bluetooth connectivity issues between a phone and a car are often caused by incompatibilities or bugs in the car's Bluetooth stack, which can be resolved by updating the car's firmware. The technician should prioritize updating the car's system before considering hardware replacement or more drastic phone resets.
A customer complains that their iPhone's Wi-Fi keeps disconnecting and reconnecting. They have already rebooted the phone and the router. Which of the following is the MOST likely cause?
Explanation: This scenario tests knowledge of common mobile Wi-Fi issues. After basic steps, forgetting and reconnecting to the network often resolves profile corruption or authentication problems.
