Hi Amy, you always have to restore backups in reverse order. Level 0 means a full backup (in this question every month), level 1 builds on the last level 0, level 2 on the last level 1 and so on. If you want to restore data, you always have to use the latest full backup first. Now you have exactly the same data of the last full backup. Referring to the question below you now have 1-4 level 1 backups (for every week of the month, depending on the current date). It only makes sense to take the latest level 1 backup. So you get the same data you had when you took the last level 1 backup. The incremental level 2 backup is made during the week and schould build on the last level 1 backup, which already has been restored. So you choose the backup of last evening (last level 2 backup).
The right answer should be B. Greetings, Hannes -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Behalf Of Lee Amy Sent: Freitag, 19.

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? Thank you very much.
