Exhibit
Error: 2024-03-15 10:32:45 ERROR [DataExtractor] Failed to connect to source database 'SalesDB' on server 10.0.0.50:1433. Error: Login failed for user 'dataminer'. Reason: An attempt to login using SQL authentication failed. Server is configured for Windows authentication only.

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
✓
Enable Mixed Mode authentication on the SQL Server
The error indicates that the server is configured for Windows authentication only, but the login attempt used SQL authentication. Enabling Mixed Mode authentication allows both Windows and SQL authentication, resolving the issue.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Change the server firewall to allow port 1433
Why it's wrong here
The error is about authentication, not network connectivity.
- ✓
Enable Mixed Mode authentication on the SQL Server
Why this is correct
Mixed Mode allows SQL authentication, which matches the login attempt.
- ✗
Use a different extraction tool that supports Windows authentication
Why it's wrong here
Changing tools doesn't address the authentication mode mismatch; the server configuration is the root cause.
- ✗
Grant the 'dataminer' user SELECT permissions
Why it's wrong here
Permissions are irrelevant because the login itself failed before any database access.
