220-1101 Mobile Device Application Support — Timed 10 Questions

Question 1

A user reports that after a recent iOS update, their banking app crashes every time they try to log in. Other apps work fine. The app was working before the update. What is the most likely cause and solution?

Accepted Answer

The banking app is not compatible with the new iOS version and needs an update from the developer.. This question tests understanding of app compatibility with OS updates. iOS updates can deprecate APIs or change security requirements, causing older apps to crash. The app developer must release an update to support the new OS. The technician should check for an app update in the App Store, as the developer likely has a fix.

Answer

The iOS update corrupted the app's data; reinstalling the app will fix it.

Answer

The user's account has been locked due to multiple failed login attempts.

Answer

The iOS update changed the device's security settings, blocking the app.

Question 2

A user on a corporate iPhone cannot receive push notifications from the company's email app, even though notifications are enabled in the app settings. Other apps on the phone receive notifications normally. What should the technician check first?

Accepted Answer

Check the notification settings for the email app in iOS Settings.. This question tests troubleshooting of mobile app notifications. Since only one app is affected, the issue is likely app-specific. Checking the app's notification settings within iOS (Settings > Notifications > [App]) is the correct first step, as the user may have enabled notifications in the app but iOS-level permissions could be blocking them.

Answer

Verify that the device is not in Do Not Disturb mode.

Answer

Reinstall the email app to reset its configuration.

Answer

Update the iPhone to the latest iOS version.

Question 3

A technician is configuring a company-issued Android tablet for a field worker. The worker needs to use a specific business app that requires location access to log job sites. What should the technician do to ensure the app works correctly?

Accepted Answer

Grant the location permission when the app requests it.. This question tests understanding of mobile app permissions. For an app that needs location data to function, the technician must grant the location permission when prompted or via settings. Denying or ignoring the permission will prevent the app from accessing location services, leading to malfunction.

Answer

Disable location services to save battery.

Answer

Install a third-party location spoofing app.

Answer

Set the tablet to Airplane mode to prevent network interference.

Question 4

A user complains that their iOS device's screen brightness automatically dims when using a particular streaming app, but stays normal with other apps. The auto-brightness setting is enabled. What is the most likely reason?

Accepted Answer

The app has its own brightness control that is set to dim.. This question tests knowledge of app-specific settings and OS features. Some apps, especially media players, have built-in brightness controls that override system settings. The app may have its own brightness slider or adaptive feature that dims the screen to enhance video viewing. Checking the app's settings is the correct approach.

Answer

The app is using HDR content, which requires lower brightness.

Answer

The device's ambient light sensor is malfunctioning.

Answer

The device is overheating and throttling brightness.

Question 5

A user reports that their Android phone will not install an app from the Google Play Store. The device has plenty of storage space and a strong internet connection. What is the most likely cause of this issue?

Accepted Answer

The device's operating system version is too old for the app.. This question tests knowledge of common mobile app installation issues. The most likely cause is that the device's operating system is too old to support the app, as app developers often set minimum OS requirements. Checking the app's compatibility with the device's OS version is a standard troubleshooting step.

Answer

The app is not compatible with the device's screen resolution.

Answer

The Google Play Store app needs to be reinstalled.

Answer

The user is not signed into their Google account.

Question 6

A company uses a custom Android app that stores data locally. After a recent OS update, the app fails to write data to the internal storage, but it can read existing data. The app has all necessary permissions. What is the most likely cause?

Accepted Answer

The OS update introduced scoped storage restrictions that the app does not support.. This question tests advanced knowledge of Android storage changes. Starting with Android 11, scoped storage restrictions limit how apps access shared storage. Even with permissions, apps may need to use specific APIs (like MediaStore or SAF) to write files. The app likely needs an update to comply with the new storage model.

Answer

The internal storage is full and cannot accept new data.

Answer

The app's cache needs to be cleared to free up space.

Answer

The device's SD card has been removed.

Question 7

A customer brings in an iPhone that is running iOS 15 and complains that a newly released app crashes immediately upon launch. The app requires iOS 16 or later. What is the best solution?

Accepted Answer

Update the iPhone to iOS 16 or later.. This question focuses on app compatibility with mobile operating systems. Since the app requires a newer iOS version, the only viable solution is to update the device to iOS 16 if supported. If the iPhone model cannot support iOS 16, the app cannot be used. This highlights the importance of checking system requirements before installation.

Answer

Reinstall the app from the App Store.

Answer

Restart the iPhone to clear temporary files.

Answer

Download an older version of the app from a third-party site.

Question 8

A technician is setting up a kiosk mode on an Android tablet for a retail display. The tablet will run a single app that customers use to browse products. After enabling kiosk mode via a third-party app, the tablet reboots and the kiosk app does not start automatically. What should the technician verify?

Accepted Answer

The kiosk app is set as the default home screen app.. This question involves mobile device management and kiosk configuration. Kiosk mode apps often need to be designated as the default launcher or have device admin privileges to start on boot. The technician should check that the kiosk app is set as the default home app in Android settings, as this ensures it launches automatically after reboot.

Answer

The tablet is connected to Wi-Fi for app updates.

Answer

The tablet's battery is fully charged.

Answer

The kiosk app is installed on the SD card.

Question 9

A technician is deploying a new Android app across several company tablets. The app requires access to the device's camera to scan barcodes. During testing, the app fails to open the camera on one tablet but works on others. What is the most likely cause?

Accepted Answer

The camera permission for the app has been denied.. This question focuses on mobile app permissions and hardware access. Since the app works on other tablets, the issue is specific to the failing device. The most common cause is that the camera permission was denied for that app. Checking and granting the permission in Settings should resolve it.

Answer

The tablet's camera hardware is defective.

Answer

The app is not compatible with the tablet's Android version.

Answer

The tablet's storage is full, preventing the app from saving photos.

Question 10

A user reports that after installing a new app on their Android phone, the device has become noticeably slower and the battery drains faster. What is the most likely cause?

Accepted Answer

The app is running background services that consume resources.. This question addresses common symptoms of poorly optimized or malicious apps. A newly installed app that runs background processes or has bugs can consume CPU cycles and battery, causing performance degradation. The first troubleshooting step is to uninstall the app and observe if the issue resolves.

Answer

The app is a known malware that steals personal data.

Answer

The phone's storage is full from the app installation.

Answer

The app requires a newer version of Android.
