Team,
I like the question. I'd like to see the words "full", "partial", and
"incremental" in reference to the proper types. From a grammar
standpoint could we change "After a headcrash of your harddisk, in
which order will you restore the three Backups?" to read; "What is the
proper order to restore the data after replace the disk drive."
I believe harddisk should be disk drive, but I'm 'old school'. ;-)
Best Regards,
Don Corbet

Hi all,
I'm going to have some simulation test on 117-102 and encounter a question
by following words.
Your company has a backup plan which consists in three levels. Once a month
a full backup is made (level 0), once a week a incremental backup is made
(level 1) and every evening an other incremental backup is made (level 2).
After a headcrash of your harddisk, in which order will you restore the
three Backups?
A.level 2, then level 1, then level 0
B.level 0, then level 1, then level 2
C.level 1, then level 0, again level 1, then level 2
D.level 0, then level 1, again level 0, then level 2
I don't know how to answer. Can anyone tell me how to answer this question
and tell me why?
After a headcrash, the disk is probably replaced with a blank one. So, you
would have first restore the last known good full backup to get back to a
known starting point. So you must start with level 0. That means A and C are
wrong answers.
Levels 1 and 2 are incremental backups, but the question is not 100% clear. 1
is obviously a backup of the difference from 0, but what exactly is 2? The
difference from 0? From 1? To answer, look at B and D.
D makes no sense at all. Why on earth would anyone restore the
original, add a
next version then put the old one back? Makes no sense. That leaves B as the
remaining answer.
This is a classic case of a silly question that is correctly answered by
finding dumb possible answers, not by knowing the subject matter. It is also
ambiguous.
