220-1102 Practice Question: A small business deploys 20 Android tablets for…
A small business deploys 20 Android tablets for inventory management. The tablets must remain in a single app (the inventory app) and prevent users from accessing settings or other apps. Which Android feature should you enable to lock the devices into this single-app mode?
⚠ Common exam trap
Test-takers frequently confuse 'restricted profiles' (which limit app access but still allow app switching) with 'screen pinning' (which truly locks the device to one app), leading them to select option C instead of the correct B.

Correct answer & explanation
✓
Use the Screen Pinning feature in Security settings.
Screen Pinning (option B) is the correct Android feature to lock a device into a single app. When enabled, it prevents users from leaving the pinned app, accessing the home screen, recent apps, or notification shade without entering a PIN or password. This is ideal for kiosk-mode deployments like inventory management tablets, as it restricts the device to exactly one application.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable Guest Mode from the user switcher.
Why it's wrong here
Guest Mode on Android creates a temporary, ephemeral user profile that is cleared upon exit, providing a clean slate for a temporary user. While it isolates the guest's data from the primary user, it does not inherently restrict the guest to a single application. A user in Guest Mode retains the ability to navigate the device's home screen, open various installed applications, and access system settings, which is contrary to the requirement of locking the device to a specific inventory app.
- ✓
Use the Screen Pinning feature in Security settings.
Why this is correct
Screen Pinning, also known as "Pin windows" or "App pinning," is an Android security feature designed to lock the device to a single application. Once activated, the user cannot exit the pinned application, access other apps, or navigate to system settings without first entering a predefined PIN, pattern, or password. This mechanism effectively prevents unauthorized users from accessing sensitive device functions or other applications, making it ideal for dedicated-purpose devices like inventory tablets.
- ✗
Set up a separate user account with restricted profile.
Why it's wrong here
A restricted profile on Android allows an administrator to create a secondary user account with granular control over which applications are accessible. While this feature can prevent access to specific apps or content, it does not enforce a single-application lock. Users operating under a restricted profile can still switch between any of the applications explicitly permitted by the administrator, navigate the home screen, and potentially access certain limited settings, which fails to meet the requirement of confining the device to just the inventory application.
- ✗
Activate Factory Reset Protection (FRP).
Why it's wrong here
Factory Reset Protection (FRP) is a security feature designed to prevent unauthorized individuals from using a device after it has been factory reset. It requires the previous Google account credentials to be entered before the device can be set up and used again, effectively acting as an anti-theft measure. However, FRP has no bearing on the device's operational state or the applications accessible during normal, active use, and therefore offers no mechanism to restrict a user to a single inventory application.
