Databricks Certified Data Engineer - Associate

The correct answer is A (Avoiding vendor lock-in).

Explanation:

Embracing open source technologies in the Databricks Lakehouse Architecture provides several benefits, but the most direct benefit mentioned in the context of open source is avoiding vendor lock-in. Open source technologies allow organizations to:

1. Avoid vendor lock-in - By using open standards and open source technologies, organizations are not tied to proprietary formats or systems that would make it difficult to migrate to other platforms.
2. Increase flexibility - Open source technologies can be deployed across different cloud providers and on-premises environments.
3. Leverage community innovation - Benefit from contributions and improvements from a broad community of developers.

While options B (Simplified governance), C (Ability to scale workloads), and D (Cloud-specific integrations) are also benefits of the Databricks Lakehouse Architecture, they are not specifically tied to the open source aspect. The ability to avoid vendor lock-in is a key advantage of using open source technologies in any architecture.
