Hey all! I just finished the Van Sander book and I'm looking to get started on my RHCE (EX294) prep since my RHCSA is about to expire in 6 months. The issue is that my job requires me to be onsite, and I don't have access to my GNS3 lab right now. I thought about setting up a mini-GNS3 lab on my laptop, but I ran into problems with the WNIC not allowing NAT, which prevents me from downloading packages until I figure out a workaround. So, I'm exploring online lab options that would be suitable for practicing and would mimic the practice exam from Van's book. Any suggestions? If I can't find something good, I might have to rethink my job situation since it's not the best fit for my skills anyway.

For web-based labs, I highly recommend checking out Katacoda and AWS Cloud9. They require no setup and are great for practicing RHCE skills with interactive scenarios.
If you're looking for a straightforward solution, spinning up servers on Azure works well for me. I just create a template, launch the servers I need for practice, and terminate them when I'm done. The cost is minimal, and it’s a flexible way to get hands-on experience.
You could use the RHEL ISO as a local repository. There's a Red Hat document on it for RHEL 7, which might still apply to newer versions. This way, you can manage installations without needing internet access. Plus, there's a section in Sander's book that covers setting up appstream and baseos repos.
I’m currently on chapter 11 of the book, and I haven't needed to install packages outside of the RHEL ISO. You could also use a laptop with VirtualBox to run RHEL as a VM, which bypasses the need for internet entirely.
