What is the general function of a CI/CD tool such as Jenkins?

To automate the build, test, and deployment pipeline

To provide a graphical interface for editing configuration files

To monitor network traffic and analyze packets

To manage user authentication and access control

How does effective collaboration support a DevOps culture?

By ensuring that only senior engineers make decisions

By requiring all communication to happen through a single tool

By eliminating the need for automated testing

By breaking down silos between development and operations teams

A network team is responsible for both development and operations of Junos configurations. They want to reduce the time between identifying a needed change and implementing it, while also ensuring the change is safe. Which approach best embodies the DevOps principle of automation?

Use a ticketing system to track changes and apply them during maintenance windows

Have developers directly access production devices to make changes

Automate the testing and deployment of configuration changes using a CI/CD pipeline

Manually review and apply each change to ensure accuracy

A network team manages Junos devices using a central Git repository for configuration files. They want to adopt a DevOps culture by reducing manual handoffs between engineers who write configs and the operations team that applies them. Which practice best aligns with DevOps principles?

Automate the deployment pipeline so that approved changes from Git are applied to devices using a tool like Ansible or PyEZ.

Use a shared spreadsheet to track configuration changes and apply them during the next maintenance window.

Require all configuration changes to be manually entered by the operations team after engineers email the changes.

Have engineers push changes directly to production devices after peer review in Git.
