Question 23/37

Which of the following is TRUE for data lake?

A. The data lake can make both of the Business Intelligence and Data Science environments more agile and more productive

B. The data lake enables organizations to gather, manage, enrich, and analyze many new sources of data, whether structured or unstructured

C. The data lake enables organizations to treat data as an organizational asset to be gathered and nurtured versus a cost to be minimized

D. The data lake can make both of the Business Intelligence and Data Science environments less agile and more productive

E. None of the above

Correct Answer: A,B,C

But per MCQ single-choice format # answer: A (though ideally A, B, C are correct).
A data lake is a centralized repository designed to store raw, structured, semi-structured, and unstructured data at scale. It provides:
Agility and productivity (Option A): Data lakes support flexible ingestion and faster access, making BI and data science environments more efficient.
Data integration (Option B): They handle multiple types of data, enabling advanced analytics and machine learning use cases.
Data as an asset (Option C): They shift perspective, treating data as a strategic resource, not just a storage cost.
Option D: Incorrect. Data lakes improve agility, not reduce it.
Option E: Incorrect, since multiple true statements exist.
Thus, the correct choice per DASCA context is Option A (with B and C also being true).
