Hey Dave, Congrats on passing your CCENT exam! We have labs in our sandbox you can use for CLI configuration and practice, sure. We have a few, but the one which I think would suit your study practice is the new Multi-IOS Cisco Test Network which provides you with a 15 node network including XR, XE and Nexus, leveraging Cisco VIRL. If you want to create your own topology you can! We’ve also included the ability to simply create a clean VIRL simulation, where you can add your own VIRL file to create your own network topology, up to 15 nodes. Head over to the sandbox https://developer.cisco.com/site/sandbox/ to get started! All the best with your studies my friend, keep me posted when you pass your CCNA. :)
