| I have been getting conflicting answer on this specific question.
What is the cheapest method to implement fault tolerant??
A. RAID 5
B. Disk duplexed
The answer should be RAID 5 right????? | |

I also disagreed with them in the beginning, but then I came to the conclusion....
1) Duplexing = 2 controllers and 2 harddrives
2) Raid 5 = minimum of 3 harddrives.
These days most pc's come out with more than one controller (say from a pentium 1 up) thus all you need to get is 1 extra harddrive.
With Raid 5 (Striping with Parity) you will have to buy 2 extra harddrives.
Answer your question?

Just passed my Essentials exam yesterday, halfway throught the MCSE... yay 
Not being able to see correct answers after the test can be really frustrating (definitely when you know you used some guesswork).
I agree with Suzie's comments, however you can look at it from a different angle as well. RAID5 could come out cheaper since you're using less resources. Only 50% disk usage for duplexing and 75% with RAID5. Plus leaving you with an extra controller.
Anyway, not sure about the correct answer but hope you won't get too many of those questions :P
