   What is the key difference between declarative and imperative infrastructure automation?

   • ADeclarative is only used for provisioning, while imperative is only used for configuration management
   • BDeclarative specifies the desired end state, while imperative specifies the exact steps to achieve it
   • CDeclarative requires manual intervention, while imperative is fully automated
   • DDeclarative uses scripts, while imperative uses configuration files

   In the infrastructure as code workflow, why is testing the code before deployment important?

   • ATo replace the need for version control
   • BTo generate documentation automatically for the infrastructure
   • CTo increase the time it takes to deploy, allowing for more manual review
   • DTo ensure that the code is syntactically correct and will produce the expected infrastructure without errors

   A network team is implementing IaC for their device configurations. They want to ensure that any change to the infrastructure code is traceable to a specific change request and can be rolled back if needed. They also want to enforce that all changes are reviewed by at least one other engineer. Which version control workflow best meets these requirements?

   • AUse a single shared branch with direct commits
   • BUse Git with feature branches, pull requests, and protected main branch
   • CUse a version control system without branch protection
   • DStore configuration files in a database

   A company wants to implement a CI/CD pipeline for their infrastructure code. They use Terraform to manage cloud resources. Which step should be included in the pipeline to validate changes before applying them to production?

   • ARun 'terraform apply' directly
   • BUse 'terraform destroy' to test
   • CSkip testing and deploy manually
   • DRun 'terraform plan' and review the output

   Which statement correctly describes how Terraform enables repeatable infrastructure deployment?

   • AIt only works with a single cloud provider, ensuring consistency across that provider
   • BIt stores the current state of infrastructure and uses configuration files to converge to the desired state
   • CIt requires manual approval for every resource change, making deployment slow but safe
   • DIt generates a random configuration each time, so no two deployments are identical
