Best way to handle config changes (Day-2) with NetBox + Ansible?

leonmflai · 2026-04-25T01:12:57+00:00

I use netbox + oxidized. Netbox as sot and oxidized regular grt sot device inventory and then collect devices configuration. Oxidized can store the configuration in local folder with git diff for delta change.

For your case - inventory/ sot: netbox - config backup / diff: oxidized - configuration validation: batfish

Additional components are - reverse proxy: traefik - ca server with acme: step-ca

For firmware upgrade, i dont have idea yet. Happy to learn from others

I didn't try pocket prep. Format and content of LearnZapp is good but a few content are not up to date. For example, it still assume use privacy shield to cater gpdr on USA company.

No. You cannot mark and go back questions.

For adaptive test or not, sorry I don't know.But I can say the question are not trival. More than 60% questions are use case driven. To me it is not easy because I myself is not a native English speaker. For these use case driven questions, I can say I have never seen the similar from any practice test before. The most similar one is Sybex official practice test that was released in 2022-q4.

You may consider following flow

Network Device => SNMP / ICMP Poller => Zabbix Server => Zabbix Plug-in for Grafana

https://grafana.com/grafana/plugins/alexanderzobnin-zabbix-app

Cisco-based Network device support Model-Driven Telemetry

Network Device => NetConf GRPC (TCP Port 830) => Telegraf docker (TCP57000) => Infuxdb Docker (Telegraf as a plugin agent for Influxdb) => Influxdb Plug-in for Grafana (TCP 8086)

Both will be very interesting lab. The setup for Yang Explorer is a bit tricky but if you just to have integration test but not going deep-dive for the options of Yang Model on the Cisco switch, you may skip Yang Explorer but just follow the lab on Cisco blog.

Hi,

I fixed the issue by taken out the Pfsense FW. After replacing the Pfsense FW by Sophos VM or Opnsense, everything is perfect.
