220-1201 Practice Question: Deploying 50 tablets for a school and need to…

Answer analysis

Option-by-option breakdown

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

• ✗

  Install a screen protector on each tablet.

  Why it's wrong here

  Installing screen protectors is a physical protection measure for the device's display, aimed at preventing scratches or damage during use in a high-traffic environment like a school. While beneficial for device longevity and reducing repair costs, it is not a prerequisite or a step directly involved in the technical configuration or deployment of kiosk mode software. The operational readiness for software setup does not depend on this accessory.

• ✓

  Charge each tablet to at least 50% and apply all system updates.

  Why this is correct

  Ensuring each tablet is charged to at least 50% mitigates the risk of power loss during critical configuration steps, such as applying settings, installing applications, or performing system updates, which could lead to data corruption or an incomplete setup. Simultaneously, applying all system updates before deployment guarantees that the devices are running the latest, most stable, and secure version of the operating system. This proactive approach prevents potential compatibility issues, security vulnerabilities, or unexpected bugs that could disrupt kiosk mode functionality or require post-deployment troubleshooting.

• ✗

  Remove the SIM card from each tablet.

  Why it's wrong here

  Removing SIM cards is typically done to prevent cellular data usage, restrict network access to Wi-Fi only, or manage carrier costs. However, kiosk mode primarily focuses on locking down the device's user interface and application access, not its network connectivity method. Kiosk mode can be configured and function perfectly well whether a SIM card is present or not, as long as an appropriate network connection (Wi-Fi or cellular) is available for initial setup, application downloads, and ongoing management. Therefore, it's not a required step for kiosk mode deployment itself.

• ✗

  Replace the stock ROM with a custom firmware.

  Why it's wrong here

  Replacing the stock ROM with custom firmware, often referred to as flashing a custom ROM, is a highly technical and risky procedure that voids the manufacturer's warranty and can potentially brick the device if not executed perfectly. For enterprise deployments like a school, this practice introduces significant support challenges, creates potential security vulnerabilities due to unverified software, and complicates future operating system updates. Kiosk mode functionality is typically achieved using built-in operating system features or Mobile Device Management (MDM) solutions, making custom firmware entirely unnecessary and counterproductive for a stable, manageable deployment.
