CompTIA Data+ DA0-002 (V2) Practice Question

An analyst is attempting to connect a desktop BI tool to a new cloud data warehouse using an ODBC driver. The connection dialog accepts the credentials, but the application only shows a generic "Data source error" popup with no additional details. Before escalating the ticket to the data-warehouse team, which action is the MOST appropriate first step for gathering diagnostic information that will help identify the root cause?

  • Increase the driver's command-timeout value from 30 to 300 seconds and attempt the connection again.

  • Switch the authentication method from single sign-on (SSO) to hard-coded username and password to rule out token issues.

  • Disable TLS encryption temporarily so that packets can be inspected for protocol errors with a network sniffer.

  • Enable connection-level tracing in the ODBC driver settings, reproduce the failure, and review the generated log file.
