The correct answer is that the query contains a syntax mistake. This is the most likely cause because the error log explicitly reports "repeated SQL syntax errors," which means the database engine cannot parse the SQL statement due to malformed structure—such as a missing keyword, incorrect clause order, or mismatched parentheses—causing the dashboard refresh to fail before any data is retrieved. On the CompTIA Data+ DA0-001 exam, this scenario tests your ability to interpret error logs and distinguish between syntax errors (pre-execution) and runtime errors like permission issues or missing tables. A common trap is assuming the problem lies with data or permissions, but the error message itself points directly to the query's structure. Memory tip: think of SQL syntax errors as a "grammar check" that fails before the sentence is even read—if the database can't understand the command, nothing else matters.
DA0-001 Communicating Data Insights Practice Question
This DA0-001 practice question tests your understanding of communicating data insights. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
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?
Clue words in this question
Noticing these words before you look at the options changes how you read each choice.
Clue: "most likely"
Why it matters: Probability qualifier — the question wants the most probable cause or outcome, not a guaranteed one. Eliminate low-probability options.
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.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
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
A server offline would produce a connection error, not a SQL syntax error.
✓
The query contains a syntax mistake.
Why this is correct
ORA-00933 is a SQL syntax error, indicating the query is not properly formed.
Clue confirmation
The clue word "most likely" in the question point toward this answer.
Related concept
Read the scenario before looking for a memorised answer.
✗
The user does not have permissions to access the table.
Why it's wrong here
Permission errors produce different Oracle error codes like ORA-00942.
✗
The network connection timed out.
Why it's wrong here
Network timeouts result in connectivity errors, not SQL syntax errors.
Common exam traps
Common exam trap: answer the scenario, not the keyword
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.
Detailed technical explanation
How to think about this question
SQL syntax errors are caught by the database's parser during the parsing phase of query execution, before any optimization or access control checks. The parser validates the query against the SQL grammar (e.g., ISO/IEC 9075 standard), and any deviation—such as a missing FROM clause or incorrect use of reserved words—immediately raises a syntax error. In a dashboard refresh scenario, a common real-world cause is a dynamic query built from user input that fails to escape special characters or concatenates strings incorrectly.
KKey Concepts to Remember
Read the scenario before looking for a memorised answer.
Find the constraint that changes the correct option.
Eliminate answers that are true in general but not in this case.
TExam Day Tips
→Watch for words such as best, first, most likely and least administrative effort.
→Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A practitioner preparing for the DA0-001 exam encounters this exact type of scenario on the job. The correct answer here is not the most general option — it is the best answer for the specific constraint described. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Real exam questions reward reading the full scenario before eliminating options, because the constraint defines which answer fits.
