NOTE: Each correct selection is worth one point.

Answer options

• A. support for batch data
• B. schema enforcement
• C. support for an Apache Spark runtime
• D. transactional consistency
• E. support for streaming data

Correct answer: B, D

Explanation

B and D are correct because Delta Lake provides schema enforcement, ensuring data conforms to a defined structure, and it offers transactional consistency, which guarantees that data operations are reliably processed. Options A, C, and E are features of both platforms but do not uniquely distinguish Delta Lake.
