The answer is that the kiosk app must be set as the default home screen app. When an Android tablet reboots, the system loads the default launcher; if the kiosk app is not designated as the home app, the standard launcher takes over and the kiosk app fails to start automatically. This is a core concept in mobile device management—kiosk mode apps require device admin privileges or default launcher status to survive a reboot. On the CompTIA A+ Core 1 220-1201 exam, this scenario tests your understanding of Android configuration for single-purpose devices, often appearing as a trap where technicians mistakenly check lock task mode or screen pinning instead. A common memory tip is “home is where the kiosk starts”—if the app isn’t the default home, it won’t come home after reboot.
220-1201 Mobile Device Application Support Practice Question
This 220-1201 practice question tests your understanding of mobile device application support. 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 setting up a kiosk mode on an Android tablet for a retail display. The tablet will run a single app that customers use to browse products. After enabling kiosk mode via a third-party app, the tablet reboots and the kiosk app does not start automatically. What should the technician verify?
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The kiosk app is set as the default home screen app.
This question involves mobile device management and kiosk configuration. Kiosk mode apps often need to be designated as the default launcher or have device admin privileges to start on boot. The technician should check that the kiosk app is set as the default home app in Android settings, as this ensures it launches automatically after reboot.
Key principle: Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
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 is connected to Wi-Fi for app updates.
Why it's wrong here
Wi-Fi connectivity is not required for the app to start automatically; it affects updates, not launch behavior.
✓
The kiosk app is set as the default home screen app.
Why this is correct
Setting the app as the default launcher ensures it starts automatically when the device boots up.
Related concept
Authentication checks who the user is.
✗
The tablet's battery is fully charged.
Why it's wrong here
Battery level does not affect whether a designated app launches on boot.
✗
The kiosk app is installed on the SD card.
Why it's wrong here
App location (internal vs. SD) does not impact auto-start behavior; moving it to internal storage would not solve the issue.
Common exam traps
Common exam trap: authentication is not authorization
Logging in proves the user can authenticate. It does not automatically mean the user is allowed to enter privileged or configuration mode. Watch for AAA authorization, privilege level and command authorization details.
Detailed technical explanation
How to think about this question
This kind of question is testing the difference between identity and permission. A user may successfully log in to a router because authentication is working, but still fail to enter configuration mode because authorization is missing, misconfigured or mapped to a lower privilege level.
KKey Concepts to Remember
Authentication checks who the user is.
Authorization controls what the user is allowed to do after login.
Privilege levels affect access to EXEC and configuration commands.
AAA, TACACS+ and RADIUS can separate login success from command access.
TExam Day Tips
→Do not assume successful login means full administrative access.
→Look for words such as cannot enter configuration mode, privilege level, authorization or command access.
→Separate login problems from permission problems before choosing the answer.
Key takeaway
Authentication proves identity; authorization controls what that identity can do after login. Both must work for full privileged access.
Real-world example
How this comes up in practice
A small business has 20 workstations on the 192.168.1.0/24 network and one public IP from its ISP. The router uses PAT (NAT overload) so all 20 devices share one public address using different source ports. NAT questions test whether you understand the four address terms and which direction each translation applies.
