Question
View the Exhibit to inspect the file system configuration on your server. Your department's backup policy is to perform a full backup to remote system disk on Saturday. On each weekday, you are to perform an incremental backup to the same remote system disk. Each incremental backup will contain only data that has been modified since the previous Saturday backup. The server file systems must remain available at all times and can never be taken offline. The backup must not only provide for the recovery of the most recent version of a file, but must also allow recovery of previous versions of a file. Following your company policy, which one describe the correct procedure to be performed on Saturday for backing tip the /data file system to a remote disk named /remote/backup?

Explanation
The question as provided is incomplete - the Exhibit image is not included, and the answer choices only show the label "On Saturday:" without any actual backup commands or procedures listed for options A, B, C, or D.
Without the actual content of the choices, it's impossible to accurately explain why A is correct or why B/C/D are wrong.
What I can tell you about the underlying concepts being tested:
- Full backup on Saturday = a level 0
ufsdump(on Solaris/UFS) or equivalent, capturing the entire filesystem. - Incremental since last Saturday (not since yesterday) = a level 1 dump each weekday, since level 1 captures all changes since the last level 0 - matching "since the previous Saturday."
- Filesystem stays online = snapshots or live dump tools must be used; the filesystem cannot be unmounted.
- Previous version recovery = multiple backup sets must be retained, not overwritten each day.
Memory tip: Think "level 1 every weekday" - because level 1 always looks back to level 0 (Saturday), giving you that Saturday-relative incremental the policy requires.
If you can share a screenshot or paste the actual text of the exhibit and choices, I can give you a precise, accurate explanation.
