restore a failed disk in a stripe volume

Hi,
here is the scenario:
You Windows 2000 Server computer contains four hard disks of different sizes. Each hard disk is
configured as a basic disk and has a single 5-GB partition. All four disks have the amount of
unpartitioned space shown in the following table:
Disk         Unpartitioned Space
Disk 0              3-GB
Disk 1              4-GB
Disk 2              3-GB
Disk 3              8-GB(i think there is a typo here)
On each hard disk, you create a second partition that uses the remaining unpartitioned space on the
disk. You create an 18-GB stripe volume that includes all four of the new partitions.
Six months later, disk 1 fails. You replace it with a new hard disk, and create the necessary partitions.
As quickly as possible, you need to retrieve the data that was contained on disk 1.
What should you do?

I have to choose one of the following:
1. Delete and re-create the stripe volume. Restore the contents of disk 1 from the most recent tape
backup.
2. Delete and re-create the stripe volume. Restore the first partition on disk 1 and then stripe volume
from a recent tape backup.

the proposed answer was the 2nd one, but i don't quite understand why. here are my questions:
1) if disk1 was physically impaired, would i be able to retrieve the data on it?(i guess the answer is no)
2) if disk1 was not physically impaired and thus failed, what could be the reasons for the failure?
3) why am i supposed to restore the "first partition on disk1" rather than restore the "contents of disk1"?
4) why am i supposed to restore "from a recent tape backup" rather than "from the most recent tape backup"?

Thanks in advance

I figured out Question 3:

You can't restore the "contents" of disk 1, coz disk one has "simple partition" and a "striped partition". The content of the disk means the WHOLE partition. You can't do that in one go. You restore the simple volume, then you restore the striped volume. That's why answer 1 is incorrect.

Thanks so much for helping me out

The new EE has a few problems. Come back later to close off this question. Glad things are all clear to you now.

One more tip: if you're going to be taking an MCP exam, study more than whatever is in the MOC (Microsoft Official Curriculum). And read the questions properly, read it out loud if you can. I can see why you got confused on this question, coz the answers are very similar. But, "apparently", there's only ONE correct answer. I also think the answer sometimes depends on the person. Eg:

Windows 2000 doesn't start, what do you do?
1) Safe Mode
2) Recovery Console
3) Last Known Good Config
4) Repair using ERD/Reinstall

The answer then is not obvious, Option is the last resort, but the other three are equally valid as a starting point.
I meant "Option 4 is the last resort".
Thanks so much for your help. see you next time!
