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 app's service principal lacks read permissions on the table
The 'table not found' error despite the table existing most likely indicates a permissions issue. Option C is correct because if the app's service principal lacks read permissions, the app cannot access the table, resulting in a 'not found' error. Option A is wrong because a missing required column would cause a validation or submission error, not a 'table not found' error. Option B is wrong because the developer verified the table exists, so renaming would have been noticed. Option D is wrong because a deprecated connector would cause connection issues, not a table-specific error.
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 table has a missing required column
Why it's wrong here
A missing required column would typically cause a validation or submission error, not a 'table not found' error.
- ✗
The table was renamed after the app was published
Why it's wrong here
If the table was renamed, the app would likely fail to find the table, but the developer verified the table exists, so this is not the cause.
- ✓
The app's service principal lacks read permissions on the table
Why this is correct
The app's service principal lacking read permissions can result in a 'table not found' error even though the table exists, because the app cannot access it.
- ✗
The app uses a deprecated connector
Why it's wrong here
A deprecated connector could cause connection issues, but the error 'table not found' points to a permission or naming issue, not connector deprecation.
