Explanation
YANG (Yet Another Next Generation) is a data modeling language defined in RFC 6020/7950 specifically for NETCONF and RESTCONF protocols. Its two key advantages are: (B) multi-platform vendor abstraction - YANG models allow a single standardized model to describe configuration across multiple vendors' devices, enabling vendor-neutral automation; and (C) designed to reflect networking concepts - YANG natively models constructs like interfaces, routing tables, and VLANs, making it intuitive for network engineers. YANG does not map to JavaScript (A), compile to device executables (D), or use a CLI interface (E).
