A data engineer needs a reporting solution with predefined filters and the ability to download CSV files. Which option is best?

• A. Developing a dynamic dashboard that refreshes daily
• B. Generating a weekly executive summary
• C. Creating a self-service portal on the company's intranet
• D. Building an email template to request ad hoc reports

Answer: (C)

Providing a self-service reporting portal with predefined filters and CSV export addresses the need for consistent, governable access to data. By hosting standardized report templates on the intranet, users can run reports with fixed, approved filters (such as date ranges, regions, or product lines) and quickly download the results as CSV for further analysis. This setup ensures reproducibility, reduces back-and-forth requests, and simplifies access control and auditing since the templates are maintained centrally and exports follow a consistent format.

Other options either rely on interactive dashboards that may not enforce fixed filters or straightforward exports, or offer fixed summaries that aren’t self-serve, or require manual requests via email templates without built-in, reusable filtering or downloadable data.
