FC0-U71 Practice Question: That a desktop application crashes every time it…
A user reports that a desktop application crashes every time it tries to save a file to a network drive. Other applications work fine. Which is the MOST likely cause?
⚠ Common exam trap
Test-takers frequently assume a network-related issue (like a driver problem) because the symptom involves a network drive, but the key clue is that other applications work fine, isolating the problem to the specific application's permissions or handling of the save operation.

Correct answer & explanation
✓
Insufficient permissions on the network share
The most likely cause is insufficient permissions on the network share (D). When a desktop application crashes specifically during a save operation to a network drive, but other applications work fine, it often indicates that the application lacks the necessary write permissions to the target folder or file. This can trigger an unhandled exception in the application's save routine, leading to a crash, whereas other applications may handle the permission denial gracefully or use different access methods.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Outdated network driver
Why it's wrong here
A faulty network driver would disrupt every application using that adapter, yet only this one app fails, so the fault lies in the application's own save routine or permissions. It is tempting because driver updates genuinely resolve connectivity faults affecting all network traffic on a host.
- ✗
Insufficient local disk space
Why it's wrong here
Insufficient local disk space would affect all applications writing locally, and the reported failure occurs only when saving to a network drive. It is tempting because low disk space commonly causes save failures, and would be correct if the user could not save any file anywhere.
- ✗
Corrupted application installation
Why it's wrong here
A corrupted installation would typically crash the application regardless of destination, yet saving locally works and other applications are unaffected. It is tempting because reinstalling often fixes crashes, and would be correct if the application failed on every save, not only to the network drive.
- ✓
Insufficient permissions on the network share
Why this is correct
A network share enforces NTFS and share-level access controls, so a user lacking write permission can save locally while the application fails only when writing to that mapped drive. Other applications working fine points to share-specific permissions rather than a general network fault.
