A NETCONF client sends an request to add a new interface. The server responds with an containing an error-tag of 'invalid-value'. What does this error indicate?

The interface name contains characters that are not allowed by the YANG model.

The configuration datastore is locked by another session.

The NETCONF session is not authorized to make configuration changes.

The device does not support the edit-config operation.

What is the primary purpose of NETCONF in network automation and management?

To replace routing protocols for exchanging reachability information between devices

To provide a standardized mechanism for retrieving and modifying the configuration of network devices

To monitor network performance by collecting flow records from routers

To encrypt all network traffic between hosts on a LAN

A developer is writing a NETCONF client that must validate a configuration change against the device's YANG models before applying it. The device advertises the :validate capability. Which sequence of operations should the client use?

lock the datastore, then edit-config to apply the change.

validate with the configuration, then edit-config to apply it.

edit-config with test-option set to test-only, then edit-config with test-option set to test-then-set.

get-config with a filter, then edit-config to apply it.
