What is YANG's primary purpose in network management?

YANG (Yet Another Next Generation) is a data modeling language used to define the structure and constraints of configuration data, state data, RPCs, and notifications for network devices. Its primary purpose is to provide a standardized, human-readable, and machine-parsable way to describe the data manipulated by network management protocols like NETCONF. NETCONF then uses these YANG models to exchange configuration and operational data. Incorrect options: Transporting data is NETCONF's role, not YANG's. SNMP uses its own MIBs (Management Information Bases) for data access, not YANG. YANG can define data models for various encodings (like JSON or XML), but it doesn't translate between them; that's a separate parsing function.
