The list
The community's list of practice images for Windows, Linux and Cisco Packet Tracer, with difficulty, ratings, creators and download links, is kept in a shared spreadsheet:
Before you download
- Large and multi-part downloads are normal. Use 7-Zip to extract them, and read the README inside each image before you start.
- Try before you peek. Where a walkthrough or answer key exists, you learn far more if you work until you are truly out of ideas first.
- Cisco Packet Tracer activity files (
.pka) need Cisco Packet Tracer, which Cisco offers through its Networking Academy. - This list is unofficial and is not affiliated with CyberPatriot, the Air & Space Forces Association, Cisco or Microsoft. Each image belongs to its creator.
