11.You have been given the job of administering a new server. It houses a database used by the sales people. This information is changed frequently and is not duplicated anywhere else. What should you do to ensure that this information is not lost?

Create a backup strategy that includes backing up this information at least daily.
Prepare a proposal to purchase a backup server.
Recommend that the server be made part of a cluster.
Install an additional hard drive in the server.

Explanation: To ensure that data isn't lost, it should be backed up. The question states that the information is changed frequently, so it should be backed up frequently.

Incorrect Answers
B: A backup server usually runs backup software. This may not be necessary and is no use without a backup strategy.
C: Clustering the server would require additional servers and would be very expensive. Furthermore, depending on the type of cluster, you may only have one set of hard disks containing the information.
D: Installing an additional hard drive would only work if the data was regularly backed up to the additional hard drive. However, if the server failed, the data would still be unavailable.
