220-1202 Practice Question: A technician is configuring a company-issued…
A technician is configuring a company-issued Android tablet for a kiosk mode in a retail store. The tablet must only run the store's inventory app and prevent users from accessing other apps or settings. Which built-in Android feature should the technician use?
⚠ Common exam trap
CompTIA A+ often tests the distinction between user-level app pinning and system-level kiosk lockdown. Candidates may choose Screen Pinning because it sounds like a single-app lock, but true kiosk mode on Android requires Lock Task mode (dedicated device mode), which enforces restrictions that Screen Pinning does not.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Lock Task mode (dedicated device mode)
Android's built-in kiosk mode is Lock Task mode (also called dedicated device mode), which locks the device to a single app or set of apps and prevents users from accessing other apps, the home screen, recent apps, notifications, and system settings. It is typically configured through a device policy controller (e.g., Android Enterprise dedicated device mode). Screen Pinning is a user-level feature that temporarily locks the screen to one app; it can be exited with a PIN/password and does not provide the full system-level restrictions required for a retail kiosk.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Guest Mode
Why it's wrong here
Guest Mode creates a separate user profile but still allows switching to other apps or settings, not a true single-app lock.
- ✓
Lock Task mode (dedicated device mode)
Why this is correct
Screen Pinning locks the device to one app and requires a PIN to unpin, providing the exact kiosk functionality needed.
- ✗
Developer Options > Force GPU Rendering
Why it's wrong here
Force GPU Rendering is a performance tweak, not a security or kiosk feature; it does not restrict app usage.
- ✗
Do Not Disturb
Why it's wrong here
Do Not Disturb silences notifications but does not prevent users from opening other apps or accessing settings.
