Option A looks like it might work, but it's for a RAID-5 array, not RAID-1. I'm glad I double-checked the question.

Ha! Imagine trying to create a RAID-5 array with just two devices. That'd be like trying to repair a flat tire with a screwdriver.

Yeah, that would definitely not work. You need at least three devices for RAID-5.

Option D is funny, but it's not what the question is asking for. RAID-0 is not the same as RAID-1.

I almost chose option B, but then I realized it doesn't have the spare device specified in the question. Good catch!

User 3: Thanks for pointing that out. Option C is definitely the one to go with for creating the RAID-1 device.

The correct answer is C. The question specifically asks for a RAID-1 device with two block volumes and one spare device, and option C matches that description.
