Question about AZ-900 Mock Exam 2

[hugh]

I have a couple of questions about questions I got wrong on Mock Exam 2 for the AZ-900 course.
In one, you’re asked how many VMs and how many regions are required to provide 99.99% uptime. I answered 2 VMs and 2 regions - i.e. one VM per region. The “correct” answer was 2 VMs and 3 regions. I thought a VM was deployed in a single region, and how would you use the 3rd region in this case? I’ll review again the lecture on Compute but is this an error in the answers?

Another question asked which client computer config would be useful for Admins to run a PowerShell script. The explanation of the answer was that neither Option C nor Option D mentioned having PowerShell. I beg to differ. Option D was a Linux machine with the PowerShell Module installed. A quick Google search reveals that PS for Linux available on Alpine, Debian, RHEL, Ubuntu and others. DId I miss something?

Here is the second question. I screenshotted this and sent it as feedback.

This option flagged as incorrect states that the linux computer has the PowerShell Module. Further, I rechecked the relevant lecture, and around minute 3, it states that PowerShell can be run on Linux, Windows, and Mac.
