NETCONF provides a set of mechanisms for managing network devices.

NETCONF definesdatastoresto manage device configurations:

running: Active configuration in use

candidate: Staging area for changes before applying

startup: Configuration loaded on reboot

NETCONF operations:

: Applies changes fromcandidate → running→✅

: Deletes a specified datastore (e.g., startup) →✅

: Validates syntax/logic in thecandidate datastore→✅

Statement D is incorrect: never submits config from startup to running— that’s handled automatically at boot time, not through NETCONF commands.

Correct answer: D
