JNCIA-DevOps NETCONF And XML API Practice Question
An engineer writes a Python script using ncclient to push changes to a Junos device. After sending the configuration via <edit-config>, the script needs to make the changes active without dropping the NETCONF session lock prematurely or requiring a separate explicit commit RPC if candidate workflows are bypassed. However, using standard candidate datastore workflow, what is the exact RPC required to activate the candidate configuration?
