Reviving a 2021 NetDevOps Lab in 2026

I recently found an old bookmark to a good intro to infra as code for netdevops. It was Vista-Technology/netops-quickstart, an older but ambitious lab built around Arista cEOS, GitLab, Ansible, Batfish, Prometheus, Grafana, Loki, and Docker.

Back in the day, I wanted a way to provision new sites on the F5 as fast as possible. That meant combining VIPs and forwarding to pools based on Host header. This can be done with an iRule, but LTM policies are more effecient. I’ve created basic playbooks to create new VIPs, and then another playbook to add sites to them later, including GTM if you have that as well. Most recently I added a third playbook that requests and installs a Let’s Encrypt certificate via Cloudflare DNS-01, so the cert side of standing up a VIP is one command too.

Introduction

When configuring a Site to Site VPN, you may be wondering what the best settings are such as:

Introduction

Hey all,

These are the official exam objectives.

=================================================================
Section 1 - Troubleshoot Basic Virtual Server Connectivity Issues
=================================================================

Objective - 1.01 - Given a scenario, determine the appropriate profile setting modifications

• 1.01a - Given a scenario of client or server side buffer issues, packet loss, or congestion, select the appropriate TCP or UDP profile to correct the issue
• 1.01b - Given a scenario determine when an application would benefit from HTTP Compression and/or Web Acceleration profile

Objective - 1.02 - Given a sub-set of an LTM configuration, determine which objects to remove or consolidate to simplify the LTM configuration

These were the official 11.5 objectives but modified by me. They have been cleaned up even removed in some cases.

This objective list I prefer over the current ones that are official.

Section 1 - Maintain Application and LTM Device Health
================================================================

Objective 1.01 Given a scenario, determine the appropriate profile setting modifications.

• 1.01a - Given a scenario of client or server side buffer issues, packet loss, or congestion, select the appropriate TCP or UDP profile to correct the issue
• 1.01b - Given a scenario determine when an application would benefit from HTTP Compression and/or Web Acceleration profile

Objective 1.02 Given a subset of an LTM configuration or statistics, determine which objects to remove or consolidate to simplify the LTM configuration
