Which two protocols use YANG as an underlying data modeling language? (Choose two.)

SOAP (Simple Object Access Protocol) primarily uses XML for messaging and WSDL for service descriptions, not YANG.

NETCONF (Network Configuration Protocol) uses YANG to define the structure and content of configuration and state data exchanged between network devices and management systems.

RESTCONF is a protocol that uses YANG to define its data models, providing a REST-like interface for accessing and manipulating configuration and operational data on network devices.

REST (Representational State Transfer) is an architectural style, not a protocol that directly uses YANG; RESTCONF is a specific protocol built on REST principles that uses YANG.

HTTP (Hypertext Transfer Protocol) serves as a transport layer for many web services but does not inherently use YANG for data modeling.

SSH (Secure Shell) is a secure transport protocol, often used by NETCONF, but it does not use YANG for data modeling itself.
