Master CCNA skills by designing and deploying a resilient, multi-site enterprise network for Castle Rysen Coffee—complete with routing, security, wireless, automation, and real-world troubleshooting.
This CCNA training walks learners through designing and deploying a complete, production-ready network for Castle Rysen Coffee—a fictional but highly realistic multi-site enterprise operating in a challenging, post-apocalyptic world. Students will build a secure, scalable network spanning a central headquarters, regional fallout shelters, and dozens of district coffee shops.

Through hands-on labs, you’ll implement IPv4/IPv6 addressing, VLANs, routing (static + OSPF), wireless networks, EtherChannels, and core services like DHCP, DNS, NAT, NTP, and SNMP. You’ll also configure multilayer security (ACLs, port security, DAI, DHCP Snooping), segment guest and administrative networks, support streaming/video surveillance, and integrate automation using tools like Ansible and REST APIs.

By the end, learners gain practical experience in end-to-end network design, implementation, monitoring, troubleshooting, documentation, and automation—mirroring the real-world expectations of a modern network engineer.

Trainer

Jeremy Cioara

Hello! If we haven’t met before, my name is Jeremy Cioara. I stepped into the training world back in 1998, teaching a group of phone technicians at US West Communications about this new technology called DSL. I was 19 years old.

Things have come a long way since then… and yet some things never change: I’m still passionate about seeing others light up when what was once a confusing, discouraging topic suddenly clicks. What’s even more exciting these days is that I now bring the experience of building a company (Veeya) that actually does the stuff I teach! I’m stepping back into the virtual classroom with a renewed passion for bringing the real world into my training. Yes—there’s so much more to being successful in technology than… technology!

And yes, my friend, I still say, “I hope this has been informative for you, and I’d like to thank you for viewing.”

Practice Real Skills in Real Environments

You’ve GOT to check out our CCNA virtual labs! They're designed to make networking feel alive and achievable, right from your screen. You’ll be stepping in as the network administrator of Castle Rysen Coffee, deploying Cisco network environments for the future of mankind! Here’s what to expect:

Real-World Feel:
We're using genuine Cisco software, giving you hands-on practice with routers, switches, and configs that really mirror what you'll encounter. No more wondering if it’s your problem or the simulator malfunctioning.
Course Integration:
We've spliced these labs directly into the course interface, so as soon as we demo a concept on video, you can immediately try it yourself!
Build Confidence Fast:
Break things, fix them, experiment freely in a safe space. It's all about turning "I get it" into "I can do this" while we're on this journey together.
