   A network automation team stores all Ansible playbooks and Jinja2 templates in a Git repository. They want every push to the 'main' branch to automatically validate the playbook syntax, run a linting check, and then execute the playbooks against a lab environment. Which CI/CD pipeline configuration best achieves this?

   • AManually run the pipeline from the CI tool's web interface after each commit is reviewed.
   • BUse a Git hook on the developer's local machine to run the pipeline before pushing.
   • CConfigure a webhook from the Git server to the CI tool that triggers a pipeline job on push events to 'main'.
   • DSchedule a nightly cron job in the CI tool that pulls the latest code and runs the pipeline regardless of branch.

   A developer pushes a change to a Git repository that contains Ansible playbooks. The CI pipeline automatically runs a syntax check and a unit test. The pipeline fails because the syntax check finds an error. What is the most appropriate outcome?

   A network automation team maintains a Git repository containing Ansible playbooks that configure network devices. They want to automatically validate syntax and run unit tests on every push to the repository before any playbook is merged. Which CI/CD component should they configure to meet this requirement?

   • AA post-merge job that deploys the playbooks to a staging environment
   • BA webhook that triggers a Jenkins job to run `ansible-playbook --syntax-check` and unit tests on the pushed branch
   • CA manual step in the release process where a senior engineer reviews and runs the playbooks
   • DA cron job that runs the playbooks against production every night and reports failures
