Refer to the exhibit. What does the error message relay to the administrator who is trying to configure a Cisco IOS device?

The error message 'NETCONF error: validation-failed: Element 'test': No such module 'example-model'.' directly states that a referenced module ('example-model') could not be found, clearly indicating that the NETCONF request was made for a non-existent data model.

The presence of 'NETCONF error: validation-failed' explicitly confirms that an error occurred during processing, contradicting the statement that the request was serviced without error.

The error specifically mentions 'No such module', indicating a fundamental issue with the existence or availability of the YANG data model itself, rather than merely invalid content within an existing model.

The error message contains no information about the NETCONF running datastore being locked; the problem is specifically related to a missing data model module.
