The answer is the 'Lock task mode' or 'Pin app' feature. This setting is required because Android’s kiosk mode relies on pinning a single app to the foreground, which blocks the Home button and other system navigation keys from interrupting the app session. Without activating this mode, the dedicated device management app can run but the underlying operating system still allows the Home button to function, letting users escape the kiosk environment. On the CompTIA A+ Core 2 220-1202 exam, this scenario tests your understanding of Android enterprise configuration and the difference between simply installing a kiosk app and actually enforcing the lock task mode. A common trap is assuming a device management app alone secures the kiosk, when in fact you must explicitly enable app pinning in the security settings. Memory tip: think of "Pin to Lock" — you must pin the app to lock the Home button out.

Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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 kiosk mode on a company-owned Android tablet for customer use. After enabling the dedicated device management app, the tablet still allows users to exit the kiosk app by pressing the home button. Which setting did the technician MOST likely overlook?

Correct answer & explanation
✓
The 'Lock task mode' or 'Pin app' feature.
The technician enabled the dedicated device management app but did not activate Android's 'Lock task mode' (or 'Pin app' feature). This mode is required to pin the kiosk app to the foreground and block system navigation keys (Home, Recent Apps), preventing users from exiting the app. Without it, the Home button remains functional, allowing escape from the kiosk environment.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✗
The tablet's screen timeout setting.
Why it's wrong here
Screen timeout controls display sleep, not the ability to exit the kiosk app.
✓
The 'Lock task mode' or 'Pin app' feature.
Why this is correct
Lock task mode (or app pinning) prevents users from leaving the designated app, which is essential for kiosk mode.
Clue confirmation
The clue word "most likely" in the question point toward this answer.

Read the scenario before looking for a memorised answer.
✗
The tablet's Wi-Fi configuration.
Why it's wrong here
Wi-Fi settings do not affect app navigation or home button behavior.
✗
The device's date and time settings.
Why it's wrong here
Date and time are unrelated to kiosk mode functionality.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the distinction between enabling a dedicated device management app and actually locking the device into kiosk mode, leading candidates to overlook the mandatory 'Lock task mode' or 'Pin app' configuration step.
Detailed technical explanation
How to think about this question
Android's Lock task mode (introduced in Android 5.0) uses the DevicePolicyManager.setLockTaskPackages() method to designate a package as a kiosk app. When activated, the system disables the Home and Overview buttons, and the user cannot leave the app unless the device administrator clears the lock task. In contrast, 'Pin app' (available since Android 5.0) is a user-initiated feature that requires the user to hold Back and Overview to unpin, which is insufficient for enterprise kiosk scenarios.

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.
