Correct answer & explanation
✓
YANG models are used to model data for NETCONF and RESTCONF.
YANG (RFC 6020/7950) is a data modeling language specifically designed to model configuration and state data for network management protocols like NETCONF and RESTCONF. YANG defines the structure, constraints, and semantics of data that can be exchanged via these protocols, making it the standard for model-driven network automation.
