I thought synchronization mode was the one not supported.

Wait, so they don't support that? That's surprising!

I think request response mode is commonly used, but I vaguely recall it being mentioned as unsupported in some context. Maybe that's the answer?

I’m a bit confused about this one. I thought all modes were supported, but I guess I need to double-check the specifics on asynchronous and request response modes.

I feel like I came across a practice question that mentioned waiting for callback mode as not being supported. That could be it!

I remember studying the different service integration modes, but I'm not entirely sure which one isn't supported. I think it might be the synchronization mode?

This question seems straightforward. I'll eliminate the modes that are supported and select the one that is not - waiting for callback mode.

Okay, I remember learning about this in class. The key is to identify the mode that is not supported, which is waiting for callback mode.

Hmm, I'm a bit unsure about this. Let me think through the different service integration modes supported by Serverless Workflow.

I'm pretty confident about this one. Serverless Workflow supports request-response, synchronization, and asynchronous modes, but not waiting for callback mode.

Okay, let's think this through step-by-step. The machinery costs 80,000 rupees and will need to be replaced in 2 years at a cost of 90,000 rupees. I think the key is to figure out the most cost-effective timing for the replacement.

Synchronization mode? More like 'Synchronize your watches and run for the hills' mode. Serverless Workflow is about as coordinated as a toddler playing Twister.

I'm gonna go with D. Waiting for a callback? That's so old-school. Serverless Workflow is all about that modern, event-driven goodness. No time for that callback nonsense!

Serverless Workflow? More like 'Clueless Workflow', am I right? I bet the developers spent more time coming up with the name than actually testing the features.

I'm going with option B. Synchronization mode just doesn't fit the whole 'serverless' concept, you know? It's all about keeping things loosely coupled.

Yeah, I see what you mean. Serverless is more about independent tasks, so synchronization doesn't really fit.

I agree, serverless is all about decoupling components. Synchronization mode doesn't align with that.

I think you're right. Synchronization mode does seem to go against the serverless idea.

Nah, I'm pretty sure it's the synchronization mode that's not supported. Serverless Workflow is all about parallelism, right? Why would it need to synchronize tasks?

Hmm, I think asynchronous mode is the one that's not supported. Serverless Workflow is all about orchestrating tasks in a coordinated way, so waiting for a callback seems like it should be supported.
