WORKSHOP: HEALTHCARE DATA LAKEHOUSE IN ACTION

What distinguishes a data lakehouse from a data warehouse and data lake? 

• Only stores structured data

• Combines structured data management with flexibility for unstructured data

• Does not support AI/ML 

• Limited to cloud environments 

Which of the following is a component of the compute layer in a data lakehouse? 

• MinIO

• AWS S3 

• Apache Spark 

• Azure Blob Storage

What is the role of a data catalog in a lakehouse architecture? 

• Manages metadata and enhances data discoverability 

• Encrypts data for security

• Stores only structured data 

• Deletes obsolete data 

Which open table format supports ACID transactions in a data lakehouse? 

• CSV 

• JSON

• Delta Lake 

• Parquet

What is a primary consideration for cost control in a lakehouse architecture? 

• Using expensive proprietary databases 

• Limiting data storage capacity

• Using fixed compute resources 

• Implementing cheap object storage and pay-as-you-go compute

What does data lineage in a lakehouse help track? 

• Hardware failures 

• The origin and transformation of data

• User access history

• Cost expenditure on resources 

Which activities are crucial for ensuring data quality in a lakehouse? 

• Ignoring data validation 

• Only storing raw data 

• Implementing data cleansing and validation processes 

• Minimizing data ingestion 

What is a primary function of the monitoring and management layer in a lakehouse? 

• Performance tracking and resource optimization

• Data encryption 

• Data visualization 

• Static data storage

What is a key strategy for optimizing the storage layer in a data lakehouse? 

• Using only high-cost storage solutions 

• Storing all data in a single format

• Avoiding cloud-based storage

• Implementing data compression and tiered storage

What is NOT an approach to ensure dynamic data access control in a lakehouse environment? 

• Role-based access control (RBAC) 

• Attribute-based access control (ABAC) 

• Open access policies for all users 

• Policy-based access control
