300-420 Question 287
Select 3An enterprise network engineer is tasked with automating the deployment of multiple branch offices' network configurations using a centralized controller. The engineer wants to ensure that the automation workflow is reliable, repeatable, and scalable. Which steps should the engineer take to achieve this goal?
- A
Define a source of truth for network configurations using a version control system like Git.
- B
Manually apply the configurations to each branch office to ensure accuracy.
- C
Utilize a network automation tool such as Ansible or Cisco DNA Center to deploy configurations.
- D
Implement configuration validation and testing within the automation workflow.
- E
Use static IP addresses for all branch office devices to simplify management.
Show answer and explanation
Correct answers: A, C, D
Explanation
To achieve a reliable, repeatable, and scalable automation workflow, it is crucial to define a source of truth for configurations, use automation tools for deployment, and incorporate validation and testing. These practices ensure consistency, minimize human errors, and enable efficient management of large-scale networks. Manual deployment and static IP usage, on the other hand, are not suitable for scalable and automated environments.
- A. Correct.
Defining a source of truth using a version control system ensures that configurations are centrally stored, versioned, and trackable, which is critical for scalability and repeatability.
- B. Incorrect.
Manually applying configurations is error-prone, time-consuming, and does not align with the principles of automation.
- C. Correct.
Using a network automation tool allows the engineer to deploy configurations consistently across multiple locations, improving scalability and efficiency.
- D. Correct.
Configuration validation and testing within the workflow ensures that errors are detected early, reducing the likelihood of deployment failures.
- E. Incorrect.
Using static IP addresses may simplify management in small networks but is not scalable or dynamic for large enterprise environments with many branch offices.
