Explanation

NETCONF (Network Configuration Protocol) uses XML to encode and represent data structures, while YANG defines the structure of this data.

Common mistakes.

A. While RFC 6020 defines YANG, the actual data structures exchanged via NETCONF are represented in XML, not strictly defined as RFC 6020 itself being the representation format.
C. HTML is a web content markup language and is not used by NETCONF or YANG for network device configuration data representation.
D. YANG organizes data models into modules, which are part of a tree, but the fundamental runtime representation of the data itself via NETCONF is specifically in an XML tree format.
