What is a characteristic of the YANG model?

1. A. Associate types are optional for each leaf.
2. B. It uses containers to categorize related nodes.
3. C. It is a distributed model of nodes.
4. D. Spines are used to represent individual attributes of nodes.

Correct Answer: B
YANG (Yet Another Next Generation) is a data modeling language used to model configuration and state data of a network. It is used to define the data structure of configuration files and is widely used for network configuration and management. YANG uses containers to categorize related nodes, allowing for a hierarchical organization of the data. Types can be associated with each leaf, but they are not required. Spines are not used in YANG, and it is not a distributed model of nodes.
