Changelog

Your engineer rank now reflects real certification levels. Completing the CCNA study path at a 75–80% average earns Network Engineer, and the skill radar now grows with every graded lab and practice drill — not just the protocols you've touched once. Deeper, CCNP-level work carries you toward Architect and Principal. Because the milestones are now larger, some ranks re-based. Keep practicing and you'll climb steadily.

Stuck on a lab? Once you submit your own work for grading, you can now open “Show the solution configs” on the grading card to see the solved configuration for each device and compare it against yours. The full solution guide still unlocks when you pass.

We fixed a grading issue where an access switch's VLANs weren't captured in the exported configuration, which could mark correct VLAN work as wrong. Switches now keep their VLANs in the running-config so extraction and grading see them. Re-download an affected lab package to get the fix.

IPv6 addresses are now graded case-insensitively, so a correct answer is no longer marked wrong just because the hex digits differ in case (for example 2001:DB8 vs 2001:db8).
