Which statement is true about the YANG Validator?

The YANG Validator is a tool used to evaluate and ensure the correctness of YANG models, which define data structures and their relationships in network management protocols. The choice stating that it validates models with includes and imports highlights a key feature of the YANG language.

YANG allows for the modular design of data models through the use of included or imported models, enabling the reuse of defined data structures across different YANG files. Therefore, the YANG Validator’s capability to handle and validate these elements—specifically the includes and imports—ensures that dependencies are satisfied, and that the models work correctly together. This is essential for maintaining a coherent and harmonized set of data models in complex network configurations.

The other options do not accurately reflect the full capabilities of the YANG Validator regarding how it engages with YANG models. While validating JSON and XML objects or RESTCONF and NETCONF objects may seem relevant, they do not encompass the primary function of the YANG Validator, which is focused on validating YANG model structure and its dependencies. Additionally, the notion of supporting multiple YANG models without includes implies a lack of the modular flexibility that includes and imports offer, which is critical in effective model validation.
