Competence grid for part 2

Use this grid to judge whether your IaaS is running and you understand it. Read each row and solve the task next to it without looking anything up. If it comes easily, you have reached the goal. If not, the link in the last column takes you to the right place. Within the Swiss framework curriculum, part 2 mainly serves the competences B12.1 (system architecture), B12.2 (network architecture), B12.3 (target configurations) and B14.2 (monitoring in operations).
