220-1201 Practice Question: A technician is deploying a new Android app…
A technician is deploying a new Android app across several company tablets. The app requires access to the device's camera to scan barcodes. During testing, the app fails to open the camera on one tablet but works on others. What is the most likely cause?
⚠ Common exam trap
The 220-1201 exam often tests the distinction between hardware failure and permission denial, trapping candidates who assume a hardware defect when the issue is actually a misconfigured software permission, especially in managed device environments.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The camera permission for the app has been denied.
The most likely cause is that the camera permission for the app has been denied. On Android, apps must request runtime permissions for sensitive hardware like the camera. If the user or a policy denied this permission, the app cannot access the camera, even if the hardware is functional. This explains why the app works on other tablets where the permission was granted.
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 camera hardware is defective.
Why it's wrong here
If the tablet's camera hardware were physically defective, all applications attempting to utilize the camera module—including the default camera app or other third-party camera applications—would consistently fail to operate or produce errors. The scenario specifically states a new Android app is failing, implying other camera functions might be operational or not tested, making a universal hardware failure less probable as the sole cause for this specific app's issue.
- ✗
The app is not compatible with the tablet's Android version.
Why it's wrong here
An incompatibility between the application and the tablet's Android OS version would typically manifest across all devices running that specific Android version, assuming they are part of the same deployment. Since the problem is isolated to a single tablet, it suggests a device-specific configuration or setting, rather than a fundamental software version mismatch that would affect an entire fleet of similar devices.
- ✓
The camera permission for the app has been denied.
Why this is correct
Android's granular permission model requires explicit user consent for applications to access sensitive hardware like the camera. If the camera permission was denied for this specific new app during installation or subsequently revoked in the device's settings, the app would be prevented from initializing or accessing the camera hardware, leading to its failure to function correctly on that particular tablet. This is a common cause for app-specific hardware access issues.
- ✗
The tablet's storage is full, preventing the app from saving photos.
Why it's wrong here
While full storage would indeed prevent the app from successfully saving any captured photos or videos, it would not typically impede the initial launch of the camera interface or the camera's ability to display a live preview. The app would likely open the camera successfully, but then present an error message specifically related to storage capacity when an attempt to save an image or video is made, rather than preventing camera access altogether.
