Which option is a language for data modeling and RPCs?
- NETCONF
- YANG
- JSON
- XML
Explanation: YANG (Yet Another Next Generation) is a data modeling language specifically designed to model configuration and state data, as well as Remote Procedure Calls (RPCs) and notifications. While NETCONF is the protocol that carries these messages, YANG is the language used to define the syntax, semantics, and structure of the data and operations, utilizing specific statements like the YANG rpc statement to define protocol operations. In contrast, JSON and XML are considered data encoding formats used for transmission, and NETCONF is a management protocol rather than a modeling language.
