Why each option
YANG is a data modeling language used by NETCONF to define objects and data, representing configuration, operational, and RPC data for network devices.
The name YANG is a recursive acronym, 'Yet Another Next Generation,' and is not associated with Jerry Yang or Yahoo.
YANG is a data modeling language, not a security protocol, and therefore does not provide security beyond SSL 3.0.
YANG is a data modeling language used for defining data structures, not a scripting language that can be executed like Python.
YANG (Yet Another Next Generation) is specifically designed to be used by protocols like NETCONF to define the structured objects and data exchanged in requests and replies, ensuring consistent data representation.
YANG provides comprehensive data modeling capabilities, allowing it to represent not only device configuration data but also operational state data and remote procedure call (RPC) definitions.
