Databricks Certified Data Engineer Associate — Question 133

An organization is looking for an optimized storage layer that supports ACID transactions and schema enforcement.

Which technology should the organization use?

Answer options

• A. Delta Lake
• B. Unity Catalog
• C. Cloud File Storage
• D. Data lake

Correct answer: A

Explanation

Delta Lake is the correct choice because it provides ACID transaction support and schema enforcement, making it ideal for reliable data management. Unity Catalog, while useful for data governance, does not itself provide storage capabilities. Cloud File Storage and Data Lake do not inherently support ACID transactions or enforce schemas.
