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 developer is using a different AWS region or the table name has incorrect case.
The 'ResourceNotFoundException' indicates the table was not found. The command output lists tables in a specific region. If the table exists in another region, it will not appear. Additionally, DynamoDB table names are case-sensitive. Option A correctly identifies these as the most likely causes. Option B is incorrect because a table not in ACTIVE state would generate a different error. Option C is unlikely because the describe command uses the table name, not the ARN. Option D is incorrect because the describe command succeeded (returned a list), but the specific table was not found due to region or case mismatch.
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 developer is using a different AWS region or the table name has incorrect case.
Why this is correct
Correct. The developer may be using a different AWS region or the table name has incorrect case, causing the table not to be found.
- ✗
The table is not in ACTIVE state.
Why it's wrong here
Incorrect. If the table were not in ACTIVE state, a different error (e.g., ResourceInUseException) would occur.
- ✗
The table ARN is incorrect.
Why it's wrong here
Incorrect. The describe command uses the table name, not the ARN; the ARN is irrelevant for this operation.
- ✗
The developer does not have permission to describe the table.
Why it's wrong here
Incorrect. The command succeeded (it returned a list of tables), so the developer has permission to describe tables; the issue is that the specific table was not found.
