Oracle Cloud Infrastructure 2023 Architect Associate — Question 39

What are three characteristics of Data Lake data captured in Object Storage? (Choose three.)

Answer options

• A. mixed data types
• B. high transaction performance
• C. schema on read
• D. multiple subject areas
• E. high concurrency

Correct answer: A, C, D

Explanation

The correct answers are A, C, and D because Data Lakes accommodate various data formats (mixed data types), allow for schema to be applied at the time of reading (schema on read), and can contain data from multiple domains (multiple subject areas). Options B and E are incorrect as Data Lakes typically do not prioritize high transaction performance or high concurrency.
