Final answer:
Network automation provides benefits such as forming data models from show command output, enhancing data models with APIs, and formalizing data models with a centralized controller.
The correct option is; d. Data models are formalized and defined by a centralized controller.
Step-by-step explanation:
Network automation offers several benefits, one of which is the ability to form data models from the output of show commands that are processed by automation scripts. This allows for the automation of tasks that would otherwise require manual intervention, saving time and effort.
By using data models, network administrators can interpret the information from show commands more easily and make more informed decisions. The data models can be enhanced by APIs (Application Programming Interfaces) to provide only the most specific information, which further improves efficiency and accuracy.
In addition, network automation allows for the formalization and definition of data models by a centralized controller. This centralization helps with consistency and enables better management of network resources and configurations.
