One of the benefits of the Databricks Lakehouse Platform embracing open source technologies is that it avoids vendor lock-in. This means that customers can use the same open source tools and frameworks across different cloud providers, and migrate their data and workloads without being tied to a specific vendor. The Databricks Lakehouse Platform is built on open source projects such as Apache Spark, Delta Lake, MLflow, and Redash, which are widely used and trusted by millions of developers. By supporting these open source technologies, the Databricks Lakehouse Platform enables customers to leverage the innovation and community of the open source ecosystem, and avoid the risk of being locked into proprietary or closed solutions. The other options are either not related to open source technologies (A, B, C, D), or not benefits of the Databricks Lakehouse Platform (A, B).Reference:Databricks Documentation - Built on open source,Databricks Documentation - What is the Lakehouse Platform?,Databricks Blog - Introducing the Databricks Lakehouse Platform.

I agree, A is the right choice. The other options don't seem to be valid SQL commands for appending a new record.

The correct answer is A) INSERT INTO my_table VALUES ('a1', 6, 9.4). It's a straightforward INSERT statement to append a new record to the existing Delta table.

I'm not sure, but I think option C) INSERT VALUES ( 'a1' , 6, 9.4) INTO my_table is also a possibility.

I agree with Miles, because INSERT INTO is used to add new records to a table.
