Test Your Knowledge of DataBricks Data Engineer Associate

A data engineer is building an ETL pipeline that reads raw CSV files from cloud storage, applies transformations, and writes clean data to a Delta Lake table.

Which Databricks tool and language combination is commonly used for building ETL pipelines?

A) Apache Spark with PySpark or Spark SQL on Databricks notebooks or jobs
B) Microsoft Excel macros
C) Databricks SQL dashboards
D) Unity Catalog data explorer only

 

Correct answers: A – Explanation:
Spark with PySpark/Spark SQL is the standard ETL tool on Databricks. Excel macros (B) are not a big-data tool. Dashboards (C) are for visualization. Data explorer (D) is for browsing, not ETL.

The engineer creates a Delta table and needs to ensure query performance remains optimal as the table grows to billions of rows.

Which Delta Lake maintenance operations should be performed regularly?

A) OPTIMIZE to compact small files and VACUUM to remove old files, with optional Z-ORDER on frequently filtered columns
B) Drop and recreate the table weekly
C) Disable Delta Lake versioning
D) Move data to CSV format for faster reads

 

Correct answers: A – Explanation:
OPTIMIZE compacts files, VACUUM removes stale files, and Z-ORDER improves filter performance. Dropping tables (B) loses history. Disabling versioning (C) removes time travel. CSV (D) is slower than Delta.

An upstream data source occasionally sends duplicate records, and the engineer needs to merge new data into the target table while handling inserts, updates, and deletes.

Which Delta Lake operation supports upsert logic with insert, update, and delete handling?

A) MERGE INTO with matched and not-matched conditions
B) INSERT OVERWRITE replacing the entire table
C) Manually deleting duplicates after each load
D) Using APPEND mode and deduplicating later

 

Correct answers: A – Explanation:
MERGE INTO supports conditional insert, update, and delete in a single operation. INSERT OVERWRITE (B) replaces all data. Manual deletion (C) is error-prone. Append-then-deduplicate (D) is less efficient.

The pipeline needs to process streaming data from Kafka in near-real-time and write results to a Delta table incrementally.

Which Databricks feature supports incremental streaming data processing?

A) Structured Streaming with Delta Lake as a streaming sink using checkpoint-based exactly-once processing
B) Scheduled batch queries running every hour
C) Manual file polling with shell scripts
D) Databricks SQL dashboard auto-refresh

 

Correct answers: A – Explanation:
Structured Streaming provides incremental, exactly-once processing with Delta as a sink. Hourly batches (B) add latency. Shell scripts (C) lack fault tolerance. Dashboard refresh (D) is for visualization.

The engineer needs to set up access controls so that the analytics team can read production tables but not modify them.

How should read-only access be configured for the analytics team?

A) Grant SELECT privileges on the catalog/schema/tables through Unity Catalog permissions
B) Share the cluster admin credentials with read-only instructions
C) Create a separate copy of data in a new workspace
D) Disable write operations at the cluster level for everyone

 

Correct answers: A – Explanation:
Unity Catalog privileges enable granular read-only access. Shared admin credentials (B) are a security risk. Data copies (C) waste resources. Disabling writes globally (D) affects all users.

Multiple interdependent notebooks need to run in sequence daily — extract, transform, load, and validate — with automatic retry on failure.

Which Databricks feature orchestrates multi-task workflows with dependencies and retry logic?

A) Databricks Jobs (Workflows) with task dependencies and retry policies
B) Manual notebook execution each morning
C) A cron job on a local server calling the API
D) Running all notebooks in a single cell sequentially

 

Correct answers: A – Explanation:
Databricks Jobs orchestrate multi-task workflows with dependencies, scheduling, and retries. Manual execution (B) is unreliable. External cron (C) lacks native integration. Single-cell execution (D) lacks failure isolation.

The Delta table needs to track all historical changes so auditors can see what data looked like at any point in time.

What Delta Lake capability provides point-in-time historical data access?

A) Time travel using VERSION AS OF or TIMESTAMP AS OF queries on Delta tables
B) Keeping manual backup copies of every table version
C) Logging all changes in a separate audit table manually
D) Unity Catalog data explorer only

 

Correct answers: A – Explanation:
Delta Lake time travel automatically maintains version history for point-in-time queries. Manual backups (B), audit tables (C), and CSV exports (D) add unnecessary overhead and complexity.

The engineer needs to create a multi-hop data architecture with bronze (raw), silver (cleaned), and gold (aggregated) layers.

What is the recommended approach for implementing a multi-hop medallion architecture?

A) Create separate Delta tables for bronze, silver, and gold layers with incremental transformations flowing between each layer
B) Store all data in a single table with a status column
C) Use three separate databases on different cloud providers
D) Write all transformations in a single notebook that overwrites one table

 

Correct answers: A – Explanation:
Spark with PySpark/Spark SQL is the standard ETL tool on Databricks. Excel macros (B) are not a big-data tool. Dashboards (C) are for visualization. Data explorer (D) is for browsing, not ETL.

A data quality check reveals null values in a critical column that should never be null, and the pipeline should halt processing when this occurs.

How should data quality constraints be enforced in a Delta Lake pipeline?

A) Use Delta table constraints (CHECK constraints) or implement validation logic in the pipeline that raises exceptions on quality failures
B) Ignore null values and fix them manually later
C) Remove the column from the schema
D) Allow nulls and add a disclaimer to dashboards

 

Correct answers: A – Explanation:
CHECK constraints and pipeline validation enforce quality proactively. Ignoring nulls (B) propagates bad data. Removing columns (C) loses information. Disclaimers (D) do not fix quality.

The data engineer needs to understand the Databricks Lakehouse architecture that combines the best of data warehouses and data lakes.

What defines the Databricks Lakehouse architecture?

A) An open architecture combining the reliability and performance of data warehouses with the flexibility and scale of data lakes, built on Delta Lake
B) A traditional data warehouse with no support for unstructured data
C) A basic file storage system with no ACID transactions
D) A separate data warehouse and data lake that are not integrated

 

Correct answers: A – Explanation:
The Lakehouse unifies warehouse reliability with lake flexibility on Delta Lake. Traditional warehouses (B) lack lake flexibility. Basic storage (C) lacks transactions. Separate systems (D) are not a lakehouse.
