Databricks Generative AI Engineer Associate Question 63
Select 3You are tasked with processing a large text dataset that has been chunked into smaller pieces. Your goal is to write this data into a Delta Lake table in Unity Catalog for further analysis. Which sequence of operations should you follow to ensure the data is written correctly and is accessible by other users in your organization?
- A
Create a Delta table in Unity Catalog with the appropriate schema and permissions.
- B
Use the
spark.write.format('delta')method to write the chunked data directly into the Delta table. - C
Merge and preprocess the chunked text data into a single DataFrame before writing to the Delta table.
- D
Ensure the target Delta table is registered in Unity Catalog and assign permissions to relevant users or groups.
- E
Write the chunked text data directly into Unity Catalog without preprocessing or merging.
Show answer and explanation
Correct answers: A, C, D
Explanation
To write chunked text into a Delta Lake table in Unity Catalog, you must follow a structured approach: create the Delta table with the proper schema, preprocess and merge the chunked data into a single DataFrame to ensure consistency, and register the table in Unity Catalog while assigning permissions. These steps ensure the data is accurate, governed, and accessible to the right users.
- A. Correct.
This is correct because creating a Delta table in Unity Catalog with the appropriate schema and permissions ensures the table is properly structured and accessible to authorized users.
- B. Incorrect.
This is incorrect because writing chunked data directly without preprocessing or merging can lead to data inconsistencies and schema mismatches.
- C. Correct.
This is correct because merging and preprocessing the chunked text data into a single DataFrame ensures the data is clean and consistent before writing it to the Delta table.
- D. Correct.
This is correct because registering the Delta table in Unity Catalog and assigning permissions are necessary steps to ensure the table is governed and accessible to authorized users.
- E. Incorrect.
This is incorrect because writing chunked text data directly into Unity Catalog without preprocessing or merging can result in unstructured or inconsistent data.
