220-1201 Practice Question: A customer reports that their Android phone's…
A customer reports that their Android phone's email app crashes whenever they try to open an attachment from a work email. The app worked fine last week. What is the most likely cause of this issue?
⚠ Common exam trap
CompTIA often tests the distinction between server-side issues (like blocking attachments) and client-side corruption, where candidates mistakenly assume a server problem when the app crashes locally.
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 email app's cache or data is corrupted.
The most likely cause is that the email app's cache or data has become corrupted. This corruption can prevent the app from properly processing attachments, even though it worked previously. Clearing the app's cache or data typically resolves such crashes without affecting the email server or requiring an OS update.
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 email server is blocking attachments.
Why it's wrong here
Server-side attachment blocking would prevent download or produce a policy error, not crash the local app on open. It tempts testers because mail security gateways genuinely strip attachments. A crash on opening points to the app or its cached data, not the server's filtering rules.
- ✓
The email app's cache or data is corrupted.
Why this is correct
Corrupted cache or app data causes the email client to fail when parsing or rendering attachments, matching the sudden crash after previously working. Clearing the app's cache and data restores normal attachment handling without reinstalling.
- ✗
The phone's operating system needs to be updated.
Why it's wrong here
An OS update is a plausible maintenance cause, but a system update would typically affect many apps, not one email client opening attachments. It tempts candidates because Android updates do break compatibility. The sudden single-app crash after working last week points to corrupt app cache or data instead.
- ✗
The attachment is too large for the phone to handle.
Why it's wrong here
An oversized attachment would fail to download or time out, not crash the app when opened. It tempts candidates because attachment size limits are a real mail constraint. The crash occurs at open, so the cause lies in the app's handling of the file or its corrupted local cache.
