DAA-C01 Question 206
Single answerPerform exploratory ad-hoc analyses using Notebooks and worksheets to describe dataA retail analytics team is investigating an unexpected drop in weekly revenue for several product categories. An analyst needs to perform exploratory ad-hoc analysis in Snowflake, quickly profile the underlying sales data, visualize trends, and share the analysis with teammates for iteration. The analyst wants to use built-in Snowflake capabilities without first building a production dashboard or moving data to another platform. Which approach best meets these requirements?
- A
Use a Snowflake Notebook to query the sales tables, combine SQL with narrative text and visualizations, and share the notebook for collaborative review of the exploratory findings.
- B
Create a dynamic table that aggregates weekly revenue by category, because dynamic tables are designed primarily for interactive exploratory analysis and visual storytelling.
- C
Export the sales data from Snowflake to local CSV files and analyze it in a desktop spreadsheet, because Snowflake worksheets and notebooks do not support ad-hoc descriptive analysis.
- D
Use a standard worksheet only, because Snowflake Notebooks are intended exclusively for machine learning model training and cannot be used for SQL-based exploratory analysis.
Show answer and explanation
Correct answer: A
Explanation
The best answer is Option 1 because the requirement is exploratory ad-hoc analysis to describe data using built-in Snowflake capabilities, with an emphasis on profiling, visualization, and sharing results for collaboration. Snowflake Worksheets are useful for ad-hoc querying, but Snowflake Notebooks provide a richer environment for combining SQL, explanations, and visual outputs in one place, making them especially effective for iterative exploratory analysis. In Snowflake documentation and product guidance, worksheets are positioned for running queries and inspecting results, while notebooks support interactive analytical workflows with richer context and presentation. Dynamic tables are for maintaining transformed query results, not for interactive exploratory storytelling. Exporting data outside Snowflake is generally less desirable for governed, repeatable enterprise analysis.
- A. Correct.
Correct. Snowflake Notebooks are well suited for exploratory ad-hoc analysis because they support interactive analysis that combines code cells, SQL queries, narrative text, and visual output in a single shareable artifact. This fits the scenario of quickly describing data, profiling trends, and collaborating with teammates without needing to build a formal BI dashboard first. Notebooks are especially useful when the analyst wants to iterate, document observations, and keep analysis close to the data in Snowflake.
- B. Incorrect.
Incorrect. Dynamic tables are used to materialize the results of a query and keep them updated based on dependencies and target lag. They can support downstream analytics workflows, but they are not primarily an interactive exploration interface for describing data or presenting findings. An analyst may use a dynamic table as part of a broader solution, but it does not by itself satisfy the need for exploratory analysis, narrative context, and shareable visual investigation.
- C. Incorrect.
Incorrect. This option contradicts Snowflake best practices for in-platform analysis. Snowflake worksheets and notebooks are specifically designed to support ad-hoc querying and exploratory analysis directly against data in Snowflake. Exporting to CSV introduces unnecessary data movement, versioning issues, and governance risks, and it removes the benefits of centralized compute and security.
- D. Incorrect.
Incorrect. Worksheets do support ad-hoc SQL analysis, but the statement about Notebooks is false. Snowflake Notebooks are not limited to machine learning training; they can be used for interactive analytics and exploratory workflows. The scenario explicitly calls for visualizations, iterative collaboration, and narrative explanation, which are stronger reasons to choose a Notebook over relying only on a basic worksheet.
