An engineer just completed the installation of Cisco NSO and all of its components. During testing, some of the services are not working properly. To resolve the issue, the engineer started undeploying service instances. What can this cause?
A.
It removes the service configuration from the network device only.
B.
It removes the service configuration from the network and NSO.
C.
It removes the service configuration from NSO only.
D.
It runs the service code again when the device is out of sync.
Un-deploying Services
In some scenarios it makes sense to remove the service configuration from the network but keep the representation of the service in NSO. This is called to un-deploy a service.

but the question didn't talk about the intent... it's just asking what is going to happen if we removed the service instance... NSO is an orchestration platform, so it provides you a full view of the network. What benefit would i gain by keeping the representation of the service in NSO? just a template? i tried to remove a service instance, it got removed on both sides, network and NSO
A is correct.

You have completed this task when you attain these results:
You used Postman with the DELETE method to delete an existing L1102 instance for the loopback service and received a 204 OK response from Cisco NSO for the deleted instance with an empty body.
You verified that the service instance L1102 no longer exists, either in the Cisco NSO web GUI or in the PE1 router configuration.
So for me its B correct.
Using NSO "un-deploy" feature of service instances, it will only remove network device configuration, therefore A.
