   A network engineer needs to configure a new router. They write a script that executes the following steps: 1) enter global configuration mode, 2) create VLAN 10, 3) assign an IP address to interface GigabitEthernet0/1, 4) enable the interface. This script is an example of which approach?

   • AImperative, because it specifies the exact commands and order to achieve the configuration.
   • BDeclarative, because it describes the desired end state of the router.
   • CVersion-controlled, because the script is stored in a file.
   • DIdempotent, because running the script multiple times will produce the same result.

   A network team is evaluating whether to use Ansible or Terraform for automating their network infrastructure. They need to manage the configuration of existing devices (e.g., VLANs, ACLs, routing protocols) and also provision new virtual network functions in a cloud environment. Which statement best describes the appropriate use of these tools?

   • AUse Ansible for configuration management of existing devices and Terraform for provisioning new cloud resources.
   • BUse Ansible for both configuration management and provisioning because it is agentless.
   • CUse either tool for both tasks because they are interchangeable.
   • DUse Terraform for both configuration management and provisioning because it is declarative.
