Explanation

YANG Data Model Protocols Explanation

Wait - there is an error in the provided answer key. The correct answers should be C (RESTCONF) and... NETCONF, not "NFTCONF" (option E). NETCONF (Network Configuration Protocol, RFC 6241) and RESTCONF (RFC 8040) are the two standardized protocols specifically designed to work with YANG data models for network device configuration and management. RESTCONF uses HTTP/HTTPS methods (GET, POST, PUT, DELETE) with YANG-structured data, while NETCONF uses XML-based RPC operations over SSH.

Why the distractors are wrong:

  • A (HTTPS) is a transport mechanism used by RESTCONF, not a protocol paired directly with YANG
  • B (SSH) is similarly a transport layer used by NETCONF, not a YANG protocol itself
  • D (TLS) is another transport/security protocol, not a network management protocol that uses YANG

Memory Tip: Think "YANG needs a NET to REST on" - NETCONF and RESTCONF are the two protocols built to carry YANG-modeled data. If your exam lists "NFTCONF," recognize it as a likely misprint for NETCONF and select accordingly.
