Data Lake

Correct Answer: Data lineage in a data lake architecture provides a complete record of the journey of data from its origin to its current location. It helps users understand the lineage of data, its transformations, and its quality over time.

Data lineage is a critical capability of data lake architecture. It provides insights into the source and transformation process of data, facilitates regulatory compliance, and improves data quality. The other options do not accurately describe the purpose of data lineage in data lake architecture.

Correct Answer: Data virtualization provides a unified view of data from multiple sources without replication of data.

Data virtualization is a technique that allows data to be accessed and integrated from multiple sources without physically replicating the data. This provides a unified view of the data, which ensures data consistency and eliminates data silos.

Correct Answer: It provides scalability, elasticity, and cost-effectiveness.

A cloud-based data lake provides several advantages over on-premises data lakes, including scalability, elasticity, and cost-effectiveness. With cloud-based data lake services, organizations can easily scale up and down their data storage and processing capacity as needed, only paying for what they use. This allows organizations to build and manage data lakes without incurring significant upfront infrastructure costs.
