  • Question 1
    • The DevOps team has configured a production workload as a collection of notebooks scheduled to run daily using the Jobs UI. A new data engineering hire is onboarding to the team and has requested access to one of these notebooks to review the production logic. What are the maximum notebook permissions that can be granted to the user without allowing accidental changes to production code or data? 

      Answer: D
  • Question 2
    • A nightly batch job is configured to ingest all data files from a cloud object storage container where records are stored in a nested directory structure YYYY/MM/DD. The data for each date represents all records that were processed by the source system on that date, noting that some records may be delayed as they await moderator approval. Each entry represents a user review of a product and has the following schema:

      user_id STRING, review_id BIGINT, product_id BIGINT, review_timestamp TIMESTAMP, review_text STRING

      The ingestion job is configured to append all data for the previous date to a target table reviews_raw with an identical schema to the source system. The next step in the pipeline is a batch write to propagate all new records inserted into reviews_raw to a table where data is fully deduplicated, validated, and enriched.

      Which solution minimizes the compute costs to propagate this batch of data?


      Answer: A
  • Question 3
    • Which of the following is true of Delta Lake and the Lakehouse? 

      Answer: B
  • Question 4
    • The data engineering team has a secret scope named ‘DataOps-Prod’ that contains all secrets needed by DataOps engineers in a production workspace.

      Which of the following is the minimum permission required for the DataOps engineers to use the secrets in this scope ?


      Answer: B
  • Question 5
    • The data engineering team has a singleplex bronze table called ‘orders_raw’ where new orders data is appended every night. They created a new Silver table called ‘orders_cleaned’ in order to provide a more refined view of the orders data.

      The team wants to create a batch processing pipeline to process all new records inserted in the orders_raw table and propagate them to the orders_cleaned table.

      Which solution minimizes the compute costs to propagate this batch of data?


      Answer: B
