Question

What is a benefit of a model-driven approach for infrastructure automation?

Options

• AIt automates the translation of a declarative language of the model into an actionable script.
• BIt enforces the generation and verification of all automation scripts through the modeling
• CIt provides a small learning curve and helps system administrators with limited coding experience.
• DIt ensures that system administrators gain a good understanding of coding, and expand their

Explanation

A model-driven approach for infrastructure automation uses declarative models to define the desired state, which an automation system then translates into actionable scripts or commands.

Common mistakes.

• B. Model-driven approaches aim to abstract away the need for extensive manual script generation, focusing on the desired state rather than enforcing the generation of all imperative scripts.
• C. While some model-driven tools can simplify specific tasks, the overall learning curve for understanding complex data models, schema languages (like YANG), and the automation tools themselves can still be substantial.
• D. Model-driven automation's primary goal is often to abstract away low-level coding details, not necessarily to expand system administrators' direct coding knowledge, by focusing on declarative configurations.
