220-1201 Mobile Device Application Support Practice Test 2 — 15 Questions

Question 1

A technician is deploying 50 company-owned Android tablets for field workers. The tablets must only run a single custom business app and prevent users from accessing any other apps or settings. Which configuration method should the technician use?

Accepted Answer

Use a Mobile Device Management (MDM) solution to configure kiosk mode.. This question covers Android enterprise deployment and kiosk mode. Kiosk mode (or single-app mode) is designed to lock a device to one app, ideal for dedicated-use devices. Factory reset or standard settings cannot achieve this level of restriction.

Answer

Enable 'Developer options' and set the app as the default launcher.

Answer

Perform a factory reset and install only the custom app.

Answer

Remove the Google Play Store app from the device.

Question 2

A customer reports that their Android phone's email app crashes whenever they try to open an attachment from a work email. The app worked fine last week. What is the most likely cause of this issue?

Accepted Answer

The email app's cache or data is corrupted.. This question tests the ability to identify common app problems. An app that was working and then stops often points to a corrupted cache or data, which can be cleared in Settings without reinstalling. The other options are less likely because the app worked recently and the issue is specific to attachments.

Answer

The email server is blocking attachments.

Answer

The phone's operating system needs to be updated.

Answer

The attachment is too large for the phone to handle.

Question 3

A technician is troubleshooting an Android phone that fails to connect to a corporate Wi-Fi network using WPA2-Enterprise with PEAP. The phone connects to other Wi-Fi networks without issue. What is the most likely cause?

Accepted Answer

The CA certificate for the network is not installed or trusted.. This question tests advanced Wi-Fi configuration knowledge. WPA2-Enterprise with PEAP requires a valid CA certificate to verify the server. If the certificate is missing or untrusted, the connection will fail. The other options would affect all networks or are less specific.

Answer

The Wi-Fi adapter is faulty.

Answer

The phone's date and time are incorrect.

Answer

The phone is using a static IP address.

Question 4

A user reports that their Android phone's battery drains quickly after installing a new social media app. The phone worked fine before. What is the most efficient first troubleshooting step?

Accepted Answer

Check the app's permissions and disable background activity.. This is a common battery drain issue. Checking the app's permissions (especially background activity) is the quickest way to identify if the app is misbehaving. Uninstalling is effective but not the first step, and a factory reset is too drastic.

Answer

Uninstall the social media app immediately.

Answer

Perform a factory reset of the device.

Answer

Update the phone's operating system.

Question 5

A user has an iPhone that will not install a new app from the App Store, displaying a message that the app is 'unable to be installed'. The device has plenty of free storage. What should a technician check first?

Accepted Answer

Verify that the Apple ID is not locked or restricted.. This scenario tests basic iOS troubleshooting. When an app fails to install despite free space, the most common cause is a network restriction or Apple ID issue. Checking the Apple ID account status is the first logical step.

Answer

Check if the app is compatible with the iOS version.

Answer

Reset the phone's network settings.

Answer

Perform a factory reset of the device.

Question 6

A technician is setting up a Windows 10 tablet for a field worker who needs to use a legacy line-of-business (LOB) app that only runs in 32-bit mode. The tablet has a 64-bit processor and Windows 10 Pro. How should the technician ensure the app runs correctly?

Accepted Answer

Install the app normally; 32-bit apps are supported on 64-bit Windows.. This question tests knowledge of Windows compatibility and application support on mobile devices. Windows 10 64-bit includes WOW64 (Windows 32-bit on Windows 64-bit) by default, allowing 32-bit apps to run without additional configuration. No special steps are needed.

Answer

Install the app in a virtual machine running 32-bit Windows.

Answer

Enable Windows 8 compatibility mode for the app.

Answer

Download and install the 64-bit version of the app from the vendor.

Question 7

A user reports that their iPad's Safari browser crashes immediately upon opening, but other apps work fine. They have already restarted the device. What should the technician do next?

Accepted Answer

Clear Safari's history and website data in Settings.. This scenario tests systematic troubleshooting for a single app crash. After a restart, the next step is to clear the app's cache/data or reset its settings, as corrupted browsing data is a common cause of crashes. For Safari on iOS, this is done via Settings > Safari > Clear History and Website Data.

Answer

Perform a factory reset on the iPad.

Answer

Update iOS to the latest version.

Answer

Disable all Safari extensions.

Question 8

A user reports that their iPhone's Maps app shows incorrect GPS location, often placing them several blocks away. Other location-based apps like Uber work correctly. What is the most likely cause?

Accepted Answer

The Maps app has been denied location access in Settings.. This scenario distinguishes between device-wide GPS issues and app-specific problems. Since other apps use location correctly, the issue is likely with the Maps app's configuration, such as incorrect location permissions or a software glitch within the app.

Answer

The iPhone's GPS antenna is damaged.

Answer

The iPhone is in Airplane Mode.

Answer

The Maps app needs to be reinstalled from the App Store.

Question 9

A customer calls stating that their Android phone's messaging app is not receiving SMS messages from one specific contact, but all other contacts work. The phone has good signal strength. What is the most likely cause?

Accepted Answer

The contact's number is blocked in the messaging app.. This is a nuanced scenario where a single contact fails. The most likely cause is that the contact's number has been blocked in the messaging app or phone settings, which is a common user mistake. Other causes like carrier issues or SIM problems would affect all messages.

Answer

The phone's SIM card is damaged.

Answer

The messaging app has a corrupted database.

Answer

The carrier is experiencing an outage in the area.

Question 10

A technician is troubleshooting an iPhone that cannot install or update any apps from the App Store. The device is connected to Wi-Fi, and other internet services (Safari, email) work. What should the technician check first?

Accepted Answer

Verify that the Apple ID is signed in and has no payment issues.. This question tests advanced troubleshooting for App Store issues. Since internet works for other services, the problem is likely account-related or a restriction. The most common cause is that the Apple ID is not signed in or has a payment issue, which prevents downloads.

Answer

Check if the date and time are set correctly on the iPhone.

Answer

Reset the iPhone's network settings.

Answer

Check if the iPhone is in Low Power Mode.

Question 11

A user reports that their Android tablet frequently crashes when using a specific note-taking app, but other apps work fine. They have already cleared the app cache and data. What should you do next to resolve the issue?

Accepted Answer

Uninstall and reinstall the note-taking app.. This question tests the troubleshooting methodology for app-specific issues on mobile devices. Since the problem is isolated to one app and basic steps (cache/data clear) have failed, the next logical step is to check for app updates or reinstall the app, as updates often fix compatibility bugs.

Answer

Perform a factory reset on the tablet.

Answer

Disable the tablet's antivirus software.

Answer

Replace the tablet's battery.

Question 12

A user reports that their Android tablet's screen flickers when using a specific video streaming app, but the screen is stable in other apps and on the home screen. What hardware component is most likely at fault?

Accepted Answer

The video streaming app has a software bug or codec issue.. This scenario tests the ability to differentiate between hardware and software issues. Since the flicker only occurs in one app, the hardware (display, GPU) is likely fine. The issue is software-related, such as a codec incompatibility or app bug, not a hardware problem.

Answer

The tablet's display panel is failing.

Answer

The GPU (Graphics Processing Unit) is overheating.

Answer

The tablet's battery is swollen and pressing on the display.

Question 13

A technician is deploying several Android tablets for use as point-of-sale (POS) terminals. The tablets must run a custom POS app in kiosk mode, preventing users from accessing other apps or settings. Which configuration method should the technician use?

Accepted Answer

Use a Mobile Device Management (MDM) solution to configure kiosk mode.. This question tests knowledge of mobile device management (MDM) and kiosk mode deployment. The correct approach is to use an MDM solution to lock the device into a single-app kiosk mode, which is a standard enterprise feature for dedicated devices.

Answer

Enable Developer Options and set the app as the default launcher.

Answer

Install a third-party launcher and hide all other apps.

Answer

Root the tablets and modify the system partition to block other apps.

Question 14

A technician is configuring a company-issued Android phone for a remote employee. The employee needs to access corporate email via the Gmail app and use a VPN for secure connections. After setup, the user cannot send emails from the Gmail app, but can receive them. What should the technician check first?

Accepted Answer

Check the outgoing mail server (SMTP) settings in the Gmail app.. This question tests understanding of email configuration on mobile devices. The inability to send emails while receiving them often points to SMTP server settings or authentication issues, which are separate from incoming (IMAP/POP) settings.

Answer

Verify that the VPN is connected and routing traffic correctly.

Answer

Ensure the device has enough free storage space.

Answer

Reinstall the Gmail app from the Play Store.

Question 15

A customer complains that their iOS device's calendar app no longer syncs with their work Exchange account after a recent iOS update. Other email and contacts sync correctly. What is the most likely cause?

Accepted Answer

The calendar app needs to be re-authorized for the Exchange account.. This scenario focuses on app-specific sync issues after an OS update. The most common cause is that the app's permissions or account settings were reset during the update, requiring re-authorization or re-configuration of the Exchange account within the calendar app.

Answer

The Exchange server is down.

Answer

The iOS update removed the Exchange account from the device.

Answer

The calendar app is corrupted and must be reinstalled.
