Question

A service provider automation team is migrating from CLI screen-scraping to model-driven programmability across a multivendor network. An engineer argues that using YANG-based data models (delivered over NETCONF/RESTCONF) provides a concrete advantage over parsing free-form CLI text. Which statement BEST describes the primary benefit that YANG provides in this context?

Accepted Answer

YANG defines a structured, hierarchical schema with strict data types and constraints, so configuration and operational data can be validated and consumed programmatically in a vendor-neutral way.

Answer

YANG is a transport protocol that encrypts management sessions, replacing the need for SSH or TLS when pushing configuration to devices.

Answer

YANG automatically compresses configuration payloads to reduce bandwidth consumption on the management plane.

Answer

YANG guarantees that every vendor implements identical native models, eliminating any need for OpenConfig or vendor-specific augmentations.
