What best describes platforms or solutions driven by an object model that do not use YANG?

Platforms or solutions driven by an object model that do not use YANG are best described by Model Driven Programmability. This approach allows for the management and operation of network devices and services through a data model that is independent of the specific protocols or syntaxes used.

Model Driven Programmability relies on structured data models that can be manipulated programmatically, enabling the representation of network resources as objects. While YANG is a popular data modeling language for network configuration and state data, the concept of Model Driven Programmability encompasses any method that allows for this object-oriented manipulation of data, regardless of whether YANG is utilized.

The other options highlight specific technologies or methodologies but do not encompass the broader concept of using an object model for programmability. REST APIs form a way to interact with resources over the web but do not specifically relate to object modeling without YANG. JSON data structures are a format for data exchange and do not inherently describe an object model or address programmability. CLI-based management relies on command-line interfaces, which do not involve object models in the same way that programmability does.
