Yeah, 'ls' is the right one for listing nodes!

That's actually a typo, it should be 'docker node ls'.

I feel like I've seen 'docker node ls' in the documentation, but I can't recall if it was specifically about listing nodes.

I’m pretty sure the command is incorrect because 'Is' looks like a typo. So I would say No.

I remember practicing a similar question, and I believe the correct command does list nodes, but I’m not 100% sure.

I think the command is actually 'docker node ls', not 'Is'. So I'm leaning towards No.

I'm a bit confused on how to handle the tax basis and the scrap salvage value. I'll need to review the concepts of end-of-life cash flows to make sure I'm approaching this correctly.

I remember that 'hard Ss' focus on tangible aspects of the organization. I feel like A and C are definitely related to that.

I'm feeling pretty confident about this question. The indexing pipeline deals with things like text processing, so I'm going to select option D.

I'm pretty confident this is asking about the efficient frontier, which shows the optimal balance between risk and return. I'll go with option A.
