Question

A network engineer is automating configuration changes on perimeter routers using NETCONF. The requirement is to push a multi-line configuration change, validate it before it takes effect, and be able to discard all pending changes if validation fails — without any partial configuration ever being applied to the running device. Which NETCONF capability and workflow satisfies this requirement?

Accepted Answer

Use the candidate datastore with , then issue followed by , and use if validation fails

Answer

Write changes directly to the running datastore using <edit-config> with the merge operation, relying on syntax checking to prevent errors

Answer

Use RESTCONF PATCH operations against the running datastore since HTTP status codes indicate success or failure atomically

Answer

Push each configuration line as a separate <edit-config> call to the startup datastore so changes persist across reloads
