Oof, these Cinder questions can be a real head-scratcher. But I think Option B has it right - the scheduler does the heavy lifting in selecting the right host for volume creation. Gotta love the technical jargon, am I right?
Haha, Option D is a classic trick question! 'cinder-volume consumes and creates' - that's just too good. I bet the real answer is Option C, where the scheduler message is delivered to the volume queue.
Hmm, Option B seems like the correct answer to me. The description of the scheduler and volume processes sounds spot on. I'll be sure to remember this one for the exam.
After the scheduler schedules the host, the message is sent to the volume queue for further processing. It's a crucial part of the storage volume creation process.
Ah, I can see the issue here. Option A is clearly wrong, as Cinder doesn't directly return the volume information after a creation request. That's handled by the scheduler and volume processes. Gotta love these tricky certification questions!
