- A
Enable 'Developer options' and set the app as the default launcher.
Why wrong: Incorrect. Developer options are for testing and do not provide persistent, secure lockdown.
- B
Use a Mobile Device Management (MDM) solution to configure kiosk mode.
Correct. MDM can enforce kiosk mode, locking the device to a single app and blocking other functions.
- C
Perform a factory reset and install only the custom app.
Why wrong: Incorrect. A factory reset does not prevent users from installing other apps or accessing settings.
- D
Remove the Google Play Store app from the device.
Why wrong: Incorrect. Removing the Play Store does not block access to pre-installed apps or settings.
Question 769 of 1,020
Android Kiosk Mode Single App Deployment
This 220-1201 practice question tests your understanding of mobile device application support. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 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?
Quick Answer
The correct answer is to use a Mobile Device Management (MDM) solution to configure kiosk mode. This is because Android kiosk mode single app deployment locks the device to one custom business app, preventing access to other apps or system settings, which is exactly what the field tablets require. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of enterprise mobility management and dedicated device provisioning—a common trap is assuming a factory reset or standard settings can achieve this level of restriction, but only an MDM can enforce the necessary policies and lock the device. A helpful memory tip is to think of “MDM as the bouncer” that keeps the device focused on one app and blocks everything else.

Correct answer & explanation
✓
Use a Mobile Device Management (MDM) solution to configure kiosk mode.
A Mobile Device Management (MDM) solution with kiosk mode is the correct approach because it locks the device to a single app, disables access to system settings, and prevents users from launching other applications. MDM enforces this via device policy controllers (DPC) and Android's lock task mode, which cannot be bypassed by the user. This meets the requirement of deploying 50 tablets with a single custom business app and no access to other apps or settings.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The 220-1201 exam often tests the misconception that simply removing the Play Store or performing a factory reset is sufficient for locking down a device, when in reality only MDM-enforced kiosk mode provides the necessary system-level restrictions to prevent user access to other apps and settings.
Detailed technical explanation
How to think about this question
Android's kiosk mode is implemented using the lock task mode API, which is part of the Device Policy Controller (DPC) in Android Enterprise. When an MDM sets the app as a lock task, the system pins the app to the foreground, and the user cannot leave it unless the DPC allows it. This is enforced at the system level, overriding the home button, recents button, and notification shade, which is far more secure than simply removing the Play Store or changing the launcher.
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 220-1201 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.
