Slow Path and Medium Path aren't even relevant here!

Wait, is it really only Kernel Mode? That seems odd.

I thought it could be User Mode too, but I guess not.

Definitely A, that's how it works!

System calls are initiated from Kernel Mode.

I feel like the answer is definitely Kernel Mode, but I could be mixing it up with another topic we studied.

I’m a bit confused about the terms used here. I thought system calls could also be initiated from User Mode, but maybe that’s not the case for monolithic systems like Gaia?

I remember practicing a question similar to this, and I think it was about User Mode being the starting point for system calls.

I think system calls are initiated from Kernel Mode, but I’m not entirely sure. It feels like something we covered in class.

I remember learning about the different modes in operating systems, so I think the answer here is Kernel Mode. User programs can't directly access system resources, they have to go through the kernel via system calls. Seems straightforward enough.

Okay, let's see. In a monolithic OS, the kernel handles all the core system functions, so I'm guessing system calls would be initiated from Kernel Mode to access those low-level operations. That's my best guess, but I'm not 100% certain.

Hmm, I'm a bit unsure about this one. I know system calls are used to interact with the operating system, but I'm not totally sure where they're initiated from in a monolithic OS like Gaia. I'll have to think this through carefully.

This question seems straightforward. I'm pretty confident the answer is Kernel Mode, since system calls are typically initiated from the kernel to access system-level functions.

Easy peasy! 2 weeks is more than enough time to get this done. I'm confident I can nail this question.

This is a tricky one, but I'm going to take my time and really think through each option. I don't want to rush and miss something important.

Hmm, rubber stamps and computer signatures both need protection from unauthorized use. Could be option A.

I think the setting should be disabled when the Interactive Client is just used for monitoring. But I'm not entirely sure.

Agreed. System level functions need privileged access, so Kernel Mode.
HE

I was torn between Kernel Mode and User Mode, but Kernel Mode sounds right.
EM
Emerson

That makes sense. System calls usually run in Kernel Mode.

I think the answer is Kernel Mode, A.
