Exam 350-401 topic 1 question 534 discussion

A? YANG is a standards-based, extensible data modeling language that is used to model the configuration and operational state data, remote procedure calls (RPCs), and server event notifications of network devices. The NETMOD working group in the IETF originally designed YANG to model network management data and to provide a standard for the content layer of the Network Configuration Protocol (NETCONF) model. However, YANG is protocol independent, and YANG data models can be used independent of the transport or RPC protocol and can be converted into any encoding format supported by the network configuration protocol.

YANG is currently only really used by NETCONF and RESTCONF but that doesn't mean other things couldn't use it as it is a pretty decent schema definition language.

A is correct

While YANG is commonly used with NETCONF and RESTCONF, it is not limited to these protocols. YANG models are independent of the transport protocols, meaning they can be adapted for use with other protocols as well.

the answer is D. in the RFC indicates NETCONF https://datatracker.ietf.org/doc/html/rfc6020

A is correct

A because NETCONF and RESTCONF are not the only protocols as gRPC uses YANG as well.

YANG is a standards-based

A is correct YANG is independent of the transport protocol

agree with A
