   A network team is implementing a CI/CD pipeline for their IaC. They want to automatically validate that the code is syntactically correct and that the desired state is achievable before deploying to production. Which step should be included in the pipeline?

   • ARunning a linting and validation tool on the IaC code in a staging environment.
   • BDirectly applying the IaC code to production devices without prior testing.
   • CManually reviewing the code and then applying it to production.
   • DUsing a configuration backup tool to save the current production state before applying changes.

   What is a key characteristic of a declarative approach to Infrastructure as Code?

   • AIt uses a procedural language like Python or Bash to define infrastructure
   • BIt requires a separate script for each environment to handle differences
   • CIt defines the desired end state of the infrastructure without specifying the steps to reach it
   • DIt specifies the exact order of commands to achieve the desired configuration

   A network administrator notices that a firewall's configuration no longer matches the desired state defined in the IaC repository. The change was made manually during a troubleshooting session. What is the most appropriate way to remediate this configuration drift?

   • ARun the IaC tool to apply the desired state from the repository, which will reconcile the firewall's configuration.
   • BIgnore the drift because the firewall is still functioning correctly.
   • CManually revert the firewall configuration to the last known good state.
   • DUpdate the IaC repository to match the current manual configuration.

   What is the 'desired state' in Infrastructure as Code?

   • AThe target configuration defined in the code that the infrastructure should match
   • BThe state of the infrastructure after a manual configuration change
   • CThe state of the infrastructure before any automation is applied
   • DThe state of the infrastructure after a security incident

   How does immutable infrastructure differ from mutable infrastructure?

   • AImmutable infrastructure requires more manual configuration than mutable infrastructure
   • BMutable infrastructure is more secure than immutable infrastructure
   • CMutable infrastructure is updated in place, while immutable infrastructure is replaced with new instances
   • DImmutable infrastructure uses virtual machines, while mutable uses containers
