Correct answer: Enable data to be structured, grouped, validated, and replicated..
Why this is the answer
A data modeling language defines the structure, constraints, and relationships of data. This allows data to be organized (structured and grouped), ensures its integrity (validated), and facilitates its distribution (replicated) across systems or devices. For example, YANG is a data modeling language used in network automation to define the structure of configuration and state data. Representing finite, unchangeable network elements is too narrow; data models can describe dynamic elements. Modeling flows of unstructured data is incorrect; data modeling focuses on structured data. Providing human readability to scripting languages is a side benefit, not the primary purpose; the core purpose is data definition.
