Question 3
[Data Concepts and Environments] A report triggers an error that prevents information from being displayed. However, the report was functional before a database upgrade. Which of the following should a data analyst do first to troubleshoot the problem?
Correct Answer: C
Explanation:
The first step in troubleshooting a report that was working before a database upgrade is to confirm whether the report can still connect to the database. Database upgrades often cause connection issues due to changes in endpoints, credentials, or drivers. Before checking deeper issues like schema changes or permissions, it is best practice to first ensure the data source connection is still valid. If the connection works, then further investigation into structural changes can follow.
