Question 2: why it says that we should expand the Management tab to add the "labels". It is a label, so it can be added right away when creating the Instance, without expanding the Management. Under Management tab, we can add metadata, but at the very top of the options, when creating the VM instance, we can directly add the Label. So I don’t see a real reason to expand the management tab.
You are correct that there are many ways to do things in AWS. I’ll send your feedback to the team for review for the course.
