Pick a task on the left
Each task opens with the steps to follow, the prerequisites that must already be in place, and a diagram of how the objects relate to each other, so you can see what a task actually builds rather than only what you type.
Work from task 1 to task 195 in order and you will have designed an NSX solution, built the fabric under it from edge cluster to published workload, carved it into tenancies, and then broken it on purpose and diagnosed every fault. Tick tasks off as you go; progress is kept in this browser.
Keyboard: J and K, or the arrow keys, move between tasks. D marks the open task done.
