The correct first step is to clear the cache and data of the Google Play Store app. This resolves the insufficient storage error because a corrupted cache can cause the Play Store to misreport available space, falsely blocking downloads even when 2GB is free. On the CompTIA A+ Core 2 220-1202 exam, this question tests your ability to differentiate between genuine storage shortages and app-specific corruption—a common trap where candidates mistakenly delete user files first. Remember that Android’s storage reporting is separate from the Play Store’s internal state; clearing the app’s data forces it to rebuild its download manager without affecting your personal photos or documents. A useful memory tip: “Cache first, data second—don’t delete what you’ve kept.”
220-1102 Mobile OS and App Troubleshooting Practice Question
This 220-1202 practice question tests your understanding of mobile os and app troubleshooting. Examine the command output carefully: the correct answer depends on what the output actually shows, not on general recall alone. 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 user on an Android tablet reports that the Google Play Store is not downloading any apps, showing an error message about insufficient storage. The device's storage settings show 2GB free. What should you do first?

Correct answer & explanation
✓
Clear the cache and data of the Google Play Store app.
Clearing the cache and data of the Google Play Store app is the correct first step because the error message about insufficient storage, despite 2GB free, often indicates a corrupted cache or data within the Play Store itself. This corruption can cause the Play Store to misreport storage availability or fail to initialize downloads. Clearing these app-specific files forces the Play Store to rebuild its state, resolving the false positive without affecting user data or requiring additional free space.
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.
✗
Factory reset the tablet.
Why it's wrong here
This is a drastic measure that should only be taken after simpler solutions have failed.
✓
Clear the cache and data of the Google Play Store app.
Why this is correct
This clears corrupted temporary files that may be causing the error, and is a safe first step.
Clue confirmation
The clue word "first" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
Uninstall large apps to free up more storage.
Why it's wrong here
While this might help, it's not the first step; clearing cache is quicker and less disruptive.
✗
Check for a system update.
Why it's wrong here
System updates are important but not the immediate fix for a storage-related error; cache clearing is more direct.
Common exam traps
Common exam trap: answer the scenario, not the keyword
CompTIA often tests the misconception that 'insufficient storage' errors always require freeing up physical space, when in reality the error can stem from a corrupted app cache that misreports storage, making clearing the cache the correct first step rather than deleting apps.
Detailed technical explanation
How to think about this question
The Google Play Store uses a local database and cache to track available storage and download state. When this cache becomes corrupted—often due to interrupted downloads or app updates—the Play Store may incorrectly calculate free space, triggering a false 'insufficient storage' error even when ample space exists. Clearing the app's data (Settings > Apps > Google Play Store > Storage > Clear Data) deletes this corrupted database and cache, forcing the app to re-query the Android storage manager via the `StorageManager` API, which returns the correct free space value. This is a standard troubleshooting step recommended by Google for Play Store errors, as it does not remove user accounts or installed apps.

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.
