   A network automation team is building a CI/CD pipeline for a new tool that interacts with network devices. They need to decide which tests to include. The tool has many functions that can be tested in isolation, and it also has complex interactions with devices. They have limited time for the pipeline to run. Which testing strategy provides the best balance of coverage and speed?

   • ARun only unit tests and skip integration tests
   • BRun all possible tests, including exhaustive integration tests
   • CRun unit tests for isolated functions and a small set of integration tests for critical device interactions
   • DRun only integration tests and skip unit tests

   A network operations team currently provisions devices manually using spreadsheets and CLI commands. They want to adopt a CI/CD pipeline to automate infrastructure changes. What is the first foundational practice they should implement to enable this?

   • ACreate a detailed runbook for manual changes
   • BPurchase additional hardware for a staging environment
   • CHire more network engineers
   • DStore all infrastructure configurations as code in a version control system

   A network automation team is designing a CI/CD pipeline for a large-scale network with thousands of devices. They need to validate configuration changes without causing disruption. They have limited lab resources and want to maximize the value of automated testing. Which testing strategy should they implement?

   • ARun only syntax validation on every commit and skip integration tests
   • BRun full integration tests on all devices in the lab for every commit
   • CRun integration tests only after deployment to production
   • DRun syntax validation and unit tests on every commit, and run integration tests on a representative subset of devices in the lab

   A network operations team has a CI/CD pipeline that automatically deploys every successful build to a production-like staging environment. They now want to eliminate the manual approval step and automatically release every change that passes all tests directly to production. Which practice should they adopt?

   • AContinuous delivery
   • BContinuous integration
   • CInfrastructure as code
   • DContinuous deployment

   A network operations team has implemented a CI/CD pipeline for their device configurations. They want to eliminate the manual approval step for production deployments so that every change that passes all automated tests is automatically released to production. However, they are concerned about the risk of a faulty change reaching production. Which additional practice should they implement to mitigate this risk?

   • AA requirement for two-person approval before production deployment
   • BA longer testing phase that includes more manual testing before production
   • CAutomated rollback that reverts to the previous configuration if post-deployment health checks fail
   • DA notification email sent to the team after each production deployment
