1. A data engineering team is implementing an append-only data pipeline using Delta Lake, and wants to ensure that data is never modified or deleted once written. Which Delta Lake feature should the data engineer enable to prevent modifications to existing data?

A) Delta Time Travel
B) Delta OPTIMIZE
C) Delta VACUUM
D) Delta APPEND_ONLY

2. Incorporating unit tests into a PySpark application requires upfront attention to the design of your jobs, or a potentially significant refactoring of existing code.
Which statement describes a main benefit that offset this additional effort?

A) Improves the quality of your data
B) Validates a complete use case of your application
C) Ensures that all steps interact correctly to achieve the desired end result
D) Yields faster deployment and execution times
E) Troubleshooting is easier since all steps are isolated and tested individually

3. A data engineer created a daily batch ingestion pipeline using a cluster with the latest DBR version to store banking transaction data, and persisted it in a MANAGED DELTA table called prod.gold.all_banking_transactions_daily. The data engineer is constantly receiving complaints from business users who query this table ad hoc through a SQL Serverless Warehouse about poor query performance. Upon analysis, the data engineer identified that these users frequently use high- cardinality columns as filters. The engineer now seeks to implement a data layout optimization technique that is incremental, easy to maintain, and can evolve over time. Which command should the data engineer implement?

A) Alter the table to use Z-ORDER and implement a periodic OPTIMIZE command.
B) Alter the table to use Liquid Clustering and implement a periodic OPTIMIZE command.
C) Alter the table to use Hive-Style Partitions and implement a periodic OPTIMIZE command.
D) Alter the table to use Hive-Style Partitions + Z-ORDER and implement a periodic OPTIMIZE command.

4. A data engineering team needs to implement a tagging system for their tables as part of an automated ETL process, and needs to apply tags programmatically to tables in Unity Catalog.
Which SQL command adds tags to a table programmatically?

A) APPLY TAGS ON table_name VALUES ('key1' = 'value1', 'key2' = 'value2');
B) SET TAGS FOR table_name AS ('key1' = 'value1', 'key2' = 'value2');
C) ALTER TABLE table_name SET TAGS ('key1' = 'value1', 'key2' = 'value2');
D) COMMENT ON TABLE table_name TAGS ('key1' = 'value1', 'key2' = 'value2');

5. A data engineer is analyzing a large, partitioned retail dataset in Databricks, where each row represents a sale made by a salesperson. The dataset contains millions of records with the following schema:
sales_df: [salesperson_id: string, region: string, sale_amount: double, sale_date: date] The data engineer needs to generate a DataFrame that ranks salespeople within each region based on their total cumulative sales, with the highest seller ranked as 1. If multiple salespeople have the same total sales, they should share the same rank.
The data engineer wants to implement this logic using a PySpark window function and the dense_rank () function.
Which code snippet will perform this ranking?

A)

B)

C)

D)
