A data lake stores raw, unprocessed data in its native format, while a data warehouse stores structured, processed data.

  1. True

Answer: True

Data lakes (S3, ADLS) store raw structured/unstructured data for flexible analysis; data warehouses (Snowflake, Redshift) store curated, schema-on-write data for BI. Modern architectures use lakehouse pattern combining both. Critical for understanding data platform design in analytics exams.
