You work as a Server Administrator for company Inc. The company has a Windows-based network
environment. You need to make a balance between accessibility, security, and cost while planning
for backup. Which of the following management methods will allow you to switch to the backup site
while repairing the primary site?
A.
Near-line
B.
Backup site
C.
Off-line
D.
On-line
Explanation:
You should use the backup site management method. This method allows you to switch to the
backup site while repairing the primary site. It is a very expensive solution and it is difficult to
implement this solution properly.
disks or disk arrays are used. In this method, restore begins in milliseconds.
tapes into a tape library or drive. Access time can vary from minutes to hours or days.
method. It is used to include a tape library with restore times ranging from seconds to a few
minutes.
B
• On-line: The most accessible type of data storage usually using hard disks or disk arrays.
Restore can begin in milliseconds, but it can be relatively expensive. In addition, on-line
storage can be easily deleted or overwritten by accident or intentional action.
• Near-line: Typically less accessible and less expensive than on-line storage, usually
consisting of a tape library with the restore time beginning with seconds or minutes.
• Off-line: Requires some direct human action to physically load tapes into a tape library
or drive. Access time can vary from minutes to hours or even days if you have to order
tapes from an off-site storage area.
• Backup site or DR site: In the event of a disaster, you can switch to the backup site/
DR site while you fix or repair the primary site. Unfortunately, this method is the most
expensive solution and the most difficult to implement properly.
