I hate module 2 question 5: it's never 'simple' to get a whole bunch of users to do things on their own. 'Simple' in the sense we don't have to stand anything up, sure. But if I have SCCM or InTune already configured or if I have a great many users, it's not relatively administratively simple to get a bunch of users to do anything. Tools like SCCM are specifically to simplify things like software deployment. If it said, 'what deployment option requires the least infrastructure [or alternatively, perhaps 'setup'] to use' or something along those lines, it would be OK.
I strongly agree. If you have an organization of 10000 users, I would love to see that each of them would go on a portal and install it for themselves.
These questions are not dumps, these are reference questions that give you an indication of what to expect on your exam and how to handle answering these. The questions in this video are still valid. All the best for the exam. You can download the pdf from here: ko-fi.com/aguidetocloud/shop
