- A
Enable Guest Mode
Why wrong: Guest Mode creates a temporary user but does not prevent switching to other apps or accessing settings.
- B
Use Screen Pinning from the Overview (Recent Apps) menu
Screen Pinning locks the device to one app, and exiting requires a PIN, making it suitable for kiosk use.
- C
Boot the device into Safe Mode
Why wrong: Safe Mode disables third-party apps, which would block the POS app itself, and still allows access to settings.
- D
Install a launcher replacement app
Why wrong: While launchers can restrict access, they are not a built-in OS feature and may be bypassed; Screen Pinning is more secure.

220-1202 Mobile OS Features and Tools Practice Question
This 220-1202 practice question tests your understanding of mobile os features and tools. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A technician is configuring a shared Android tablet for a retail kiosk. The tablet should only run a single point-of-sale app and prevent users from accessing settings or other apps. Which Android feature should be used?
Answer choices
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
✓
Use Screen Pinning from the Overview (Recent Apps) menu
Screen Pinning is the correct Android feature for kiosk mode because it locks the device to a single app, preventing users from navigating away to settings or other apps. When enabled from the Overview (Recent Apps) menu, it requires a PIN or password to unpin, ensuring the point-of-sale app remains the only accessible interface. This directly meets the requirement of a dedicated retail kiosk without needing third-party software or complex configurations.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Why it's wrong here
While launchers can restrict access, they are not a built-in OS feature and may be bypassed; Screen Pinning is more secure.
Common exam traps
Common exam trap: answer the scenario, not the keyword
A common mistake is that Safe Mode or Guest Mode can restrict app access, but Safe Mode disables third-party apps and Guest Mode still allows app switching, neither of which achieves the single-app lockdown required for a kiosk.
Detailed technical explanation
How to think about this question
Screen Pinning works by calling the `startLockTask()` method in Android's ActivityManager API, which places the app into a locked task mode. Once pinned, the system blocks the Home, Overview, and Back buttons (except for the Back button if the app allows it), and the user must enter a PIN or biometric authentication to exit. In Android 9+ (API level 28), Screen Pinning can be combined with Device Policy Manager (DPM) for fully managed kiosk deployments, but the built-in feature alone suffices for a single-app scenario.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the 220-1202 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
