Hmm, I'm a bit unsure about this one. Option A seems like it might be the safest bet, waiting until all the interfaces are fully developed before starting the automation. But then we'd be losing a lot of time. Maybe option C is the way to go, but it sounds like it could be a bit more complex to set up.

I practiced a similar question and I recall that the scaling group should not exceed the maximum limit, which is 8 in this case.

This seems straightforward. The question states that the thin terminal is a hardware device used for remote desktop, not an operating system. So the answer is definitely A.

This is a tricky one. I'm not super familiar with quality management, so I'll need to think through the options logically to make my best guess.
