C seems off. Serverless should be independent.

I’m not sure about C. ECS as worker node?

B is also a good choice. GPU support is key.

I thought serverless meant no instances at all, so I'm confused.

Wait, can serverless clusters really add ECS instances? That sounds off.

B) is correct too, they do support GPU and spot instances!

I'm just going to guess A, B, and C. Serverless is confusing enough without having to figure out the right number of answers.

Wait, if it's serverless, how do you even add worker nodes? Isn't that kind of the point of serverless?

Haha, "serverless cluster" - isn't that an oxymoron? How can it be serverless if it's a cluster?

I'm pretty sure C is also correct. Serverless clusters can integrate with other compute services like ECS.

A and B are correct. Serverless clusters are indeed nodeless and can leverage GPU and spot instances.

Okay, I think I've got it. A) is correct since serverless is supposed to be "nodeless", and B) is right because it supports GPU and spot instances. I'm pretty confident about those two, but I'm not sure about C).

Ugh, I'm a bit lost on this question. I know serverless is supposed to be simpler to manage, but I'm not sure how that relates to adding ECS instances. Guess I'll have to make an educated guess on this one.

I've got a good feeling about this one. I remember learning that serverless supports GPU and spot instances, so B) is definitely one of the correct answers. Now I just need to figure out the other one.

Okay, let's see. I know serverless is supposed to be "nodeless", so A) seems like a good option. But I'm not sure about the other one - I'll have to review my notes on serverless features.

I remember practicing a question similar to this, and I think option B is also a valid choice since serverless clusters often support various instance types.

I think option A is correct because serverless clusters are designed to be nodeless, but I'm not entirely sure about the specifics.
