   A service provider is building a new data center network. They need to provision hundreds of new switches and routers from scratch, and they also need to apply consistent configuration to those devices after they are deployed. The team wants to use a single tool that can handle both the initial provisioning (creating the devices in the network management system) and the ongoing configuration enforcement. They also want to avoid manual steps and ensure that the desired state is always maintained. Which tool should they choose?

   • AA combination of Terraform for provisioning and Ansible for configuration enforcement
   • BA custom script that uses NETCONF to provision and configure all devices
   • CAnsible, because it can provision devices and enforce configuration using playbooks
   • DTerraform, because it can provision devices and manage their configuration through providers

   An operations team uses Ansible to manage a mixed fleet of IOS XR and IOS XE routers. They have written a playbook that uses the ios_config module, but it fails when run against the IOS XR devices. The team wants to use a single playbook that can handle both platforms without rewriting the entire automation. What should they do?

   • AUse the network_cli connection plugin and the iosxr_config module for IOS XR devices, and use conditionals in the playbook to select the appropriate module
   • BCreate separate playbooks for each platform and run them manually based on the device type
   • CUse the ios_config module with a conditional that checks the device platform before applying the configuration
   • DUse the ios_command module for both platforms, as it is platform-agnostic
