The Nines: prove you can keep it running
One certification per lab and per level, named after the availability it stands for, from One Nine (90 %) to Five Nines (99.999 %). You earn it twice: by solving the level's exercises in the simulator, then by passing a timed practical exam where you build and repair real systems without being able to test them, plus theory. Every certificate is signed, has its own verification page and goes straight to LinkedIn.
- Solve the levelPass 80 % of the level's exercises in the lab: you earn its free track badge.
- Take the examFrom 1 hour (Operator) to 3 hours (Architect): systems to build and repair in the simulator (70 %), and questions (30 %).
