[All Databricks Certified Data Analyst Associate Questions]

Which open-source project helps to enable the data lakehouse by adding organization, reliability, performance, and data governance to data lake architectures?

Show Suggested Answer Hide Answer
Suggested Answer: C

The correct answer is C because Delta Lake is the open-source storage layer that provides reliability and structure for data lakes. Delta Lake brings ACID transactions, scalable metadata handling, and batch/streaming support to data lake storage, which are core capabilities behind the lakehouse architecture. MLflow is for machine learning lifecycle management, Apache Spark is a distributed processing engine, and Databricks SQL is a Databricks product for SQL analytics, not the open-source storage project described.

Official documentation extract used: Databricks states that Delta Lake is ''open source software'' and provides ''ACID transactions and scalable metadata handling.''

I’m surprised Delta Lake is the answer, I thought it was more about performance than governance.

I feel like MLflow is more about model management, so I’m leaning towards Delta Lake for this one.

I’m a bit confused. Wasn't Apache Spark also mentioned in relation to performance? I need to double-check my notes.

I recall practicing a question about data lake architectures, and Delta Lake was definitely a key player in that context.

I think it might be Delta Lake, but I'm not entirely sure. I remember it being mentioned in a case study about data governance.
