DA0-002 Data Governance Practice Question
Exhibit
Error Log: 2024-07-15 08:23:45, ERROR - Query execution failed: ORA-00933: SQL command not properly ended 2024-07-15 08:23:45, ERROR - Stack trace: at com.example.DataService.getData(DataService.java:42) 2024-07-15 08:23:45, WARN - Retry attempt 1 of 3 2024-07-15 08:23:47, ERROR - Retry failed: ORA-00933: SQL command not properly ended 2024-07-15 08:23:47, ERROR - Data refresh job for dashboard 'DailySummary' failed.
Refer to the exhibit. A data analyst is troubleshooting a failed dashboard refresh. The error log shows repeated SQL syntax errors. Which of the following is the most likely cause?
⚠ Common exam trap
CompTIA often tests the distinction between error types (syntax vs. runtime vs. connectivity) to see if candidates can map the exact error message to its root cause, rather than guessing based on general troubleshooting assumptions.
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 query contains a syntax mistake.
The error log explicitly states 'repeated SQL syntax errors,' which directly indicates that the SQL query being executed is malformed. A syntax mistake in the query (e.g., missing keyword, incorrect clause order, or mismatched parentheses) will cause the database to reject the statement before any execution begins, leading to the exact error described.
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 database server is offline.
Why it's wrong here
An offline database server yields connection-refused or host-unreachable errors, not SQL syntax errors. Syntax errors are generated by the parser processing the query text, which requires a reachable server. Server-availability checks suit a refresh failing with connection errors instead.
- ✓
The query contains a syntax mistake.
Why this is correct
Repeated SQL syntax errors indicate malformed SQL statements in the query itself, such as misspelled keywords, misplaced commas or unbalanced parentheses. Correcting the query's syntax resolves the refresh failure, since the database rejects unparseable statements before execution.
- ✗
The user does not have permissions to access the table.
Why it's wrong here
Permission failures surface as authorisation or access-denied errors, not SQL syntax errors. The parser rejects malformed statements before permissions are evaluated, so the logged syntax errors point to faulty query text. Permission troubleshooting would be correct for a table-access-denied message.
- ✗
The network connection timed out.
Why it's wrong here
A network timeout produces connectivity or timeout errors, not repeated SQL syntax errors. Syntax errors are raised by the query parser evaluating malformed SQL, independent of network state. Timeout diagnosis fits a refresh that hangs or drops connection mid-execution.
