Question

A network automation engineer wants to programmatically retrieve the full operational and configuration state from a Nexus 9000 switch and integrate it into a Python-based orchestration workflow. The workflow must parse structured data, validate it against a YANG data model, and support model-driven configuration changes over a single standardized transport. Which approach best satisfies these requirements?

Accepted Answer

Use NETCONF over SSH with YANG-modeled data to retrieve and edit configuration via the running datastore

Answer

Use SNMPv3 GET/SET operations against standard and vendor MIBs

Answer

Screen-scrape 'show' command output over SSH and parse it with regular expressions

Answer

Use EEM applets with CLI actions triggered by syslog events to export configuration
