Operating NetDevOps (NDO-303)
You are a member of the operations team. Your role will be to fully utilize the NetDevOps process when performing network moves, adds, and changes. You will master the CI/CD pipeline. You will transition from command line management, to model-driven network management. You will also develop skills in network deployment testing using CML. This class includes Cisco Modeling Labs essentials.
