   A service provider is evaluating NSO to replace a homegrown automation system that uses a mix of Ansible playbooks and custom scripts. The primary goal is to reduce the complexity of managing multi-vendor services and to provide a single source of truth for service configurations. Which benefit of NSO directly addresses this goal?

   • ANSO provides a built-in configuration management database that replaces all other CMDBs.
   • BNSO automatically generates all device configurations without any human intervention.
   • CNSO eliminates the need for any scripting or automation tools.
   • DNSO provides a service-oriented abstraction layer that separates the service definition from device-specific configurations.

   In NSO, what is the typical first step in the lifecycle of a service instance?

   • AActivating the service instance in the network
   • BDeleting the service instance to clean up resources
   • CModifying the service instance to change its parameters
   • DCreating the service instance by providing the required parameters

   Which statement best describes the value of NSO for a service provider that operates a multi-vendor network?

   • AIt is the only tool that can manage devices from Cisco, Juniper, and Huawei simultaneously
   • BIt eliminates the need to maintain any device configurations because NSO generates them automatically from service definitions
   • CIt provides a single point of orchestration that abstracts device-specific differences, allowing services to be defined and deployed consistently across vendors
   • DIt replaces the need for any network engineers because all configuration tasks are fully automated

   What is the purpose of the mapping between a service model and device configurations in NSO?

   • ATo ensure that all devices in the network receive identical configurations regardless of their role
   • BTo allow the service to be defined in a vendor-neutral way while generating device-specific configurations
   • CTo eliminate the need for any device-specific configuration templates
   • DTo provide a direct one-to-one relationship between a service instance and a single device configuration

   A service provider has a service that was provisioned by NSO, but a network engineer later made manual changes to the device configurations outside of NSO. Now the service instance in NSO is out of sync with the actual device state. The team wants to bring NSO back in sync without disrupting the service. What is the recommended approach?

   • AUse NSO's 'check-sync' and 're-deploy' features to identify and reconcile the differences.
   • BUse the device's native CLI to revert the manual changes to match NSO's configuration.
   • CManually update the service instance in NSO to match the device changes.
   • DDelete the service instance and recreate it to force NSO to rebuild the configuration.
