Short version: Configuring Cisco Nexus 9000 Series Switches in ACI Mode (DCAC9K) is an awesome ACI course, which I highly recommend for anyone interested in ACI, but you need to supplement it with CiscoLive On-Demand Video Library to get the most out of it.
I can’t believe it’s been four years since my first post about learning resources for Cisco ACI and other related technologies. In 2015, 2016 and 2018, I provided recommendations for additional resources for learning ACI. Now in 2019, I would like to share two resources which I think are CURRENTLY the best options for learning Cisco ACI. If you know of better options, please let me know in the comments below! 🙂
