Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

• ✗

  Enable Developer Options and set the app as the default launcher.

  Why it's wrong here

  Enabling Developer Options allows setting a default launcher, which might initially present a single app. However, this method lacks true lockdown capabilities; users can still access system settings, the notification shade, or switch launchers through the settings menu. It offers no robust security or management features required for a dedicated kiosk environment, making it easily circumvented and unsuitable for enterprise deployments.

• ✗

  Install a third-party launcher and hide all other apps.

  Why it's wrong here

  Installing a third-party launcher and attempting to hide other applications is a superficial solution. While it might visually declutter the home screen, it does not restrict access to the device's core functionalities, such as the settings menu, notification panel, or the full app drawer, which are typically accessible through various gestures or system shortcuts. This approach fails to provide the necessary security and control for a true kiosk mode, as users can easily navigate away from the intended application.

• ✓

  Use a Mobile Device Management (MDM) solution to configure kiosk mode.

  Why this is correct

  A Mobile Device Management (MDM) solution is the industry-standard approach for deploying devices in kiosk mode. MDM platforms offer granular control to lock down Android tablets to a single application, preventing users from accessing other apps, system settings, or even physical navigation buttons. This ensures the device serves its intended purpose securely, provides remote management capabilities for updates and troubleshooting, and maintains compliance with organizational policies.

• ✗

  Root the tablets and modify the system partition to block other apps.

  Why it's wrong here

  Rooting Android tablets involves gaining superuser access to the device's operating system, which immediately voids the manufacturer's warranty and introduces significant security vulnerabilities. Modifying system partitions to block apps is an unsupported, highly risky, and unstable method that can brick devices or expose them to malware. This approach is not suitable for enterprise deployments due to its lack of official support, security risks, and inability to be centrally managed or updated.
