What kind of data can a YANG Container hold?

A YANG container is a fundamental data structure used in the YANG modeling language, which is primarily employed for defining data models for network configuration and management. The purpose of a container is to group related data nodes together in a hierarchical structure, which makes it easier to organize and manage complex configurations.

The correct answer indicates that a YANG container can hold child nodes, which can include different types of data such as lists, leaf nodes (representing scalar values), and other containers. By encapsulating these child nodes, the container provides a way to logically group and manage related information within a larger data model hierarchy.

This ability to hold child nodes allows for a more organized approach to representing complex configurations and states within network devices, as YANG containers can effectively structure data that reflects the relationships and dependencies among various elements. Thus, using a container helps in creating modular and reusable data models that can be easily understood and manipulated, aligning well with the principles of model-driven network management.
