A company performs weekly full backups of its application servers to a remote location. However,
backups take a long time to complete, which impacts production operations. After investigation, it
was found that a large part of the full backup contains redundant data.
What should you recommend to improve backup performance without changing the company’s
current backup software?

How would you differentiate deduplication from single-instance storage?

A construction company has a LAN-connected application server that is used to provide different
design views of a construction site. The application server generates four 20 MB engineering
drawing files per day. These files require a full backup at the end of each day. The company has
deployed source-based sub-file data deduplication to reduce the amount of storage needed for
backup.

On the second day after the deduplication is deployed, it is found that files generated by the
application server have some common segments with the files generated the previous day. This is
represented by the gray-colored regions in the exhibit.

Which percentage represents the storage space saved by the company on the second day?

A company replaces its legacy servers with new servers every three years. Because the
administrator needs to apply the same system settings as the legacy servers, the upgrade takes a
long time to complete. As a result, the company experiences a lengthy downtime.
The company is looking for a solution to minimize the downtime. What is a recommended
solution?

What is a key advantage of using a write-acceleration technique in a backup environment?

An organization has used a cloud-based backup service to store a large volume of its e-mail data.
The organization now wants to restore the backed up data. However, they have limited bandwidth
available for this operation.
Which restore method would you recommend for the organization?

An organization wants to deploy a centralized backup and data deduplication solution for its
backup environment. Currently, the organization is backing up data locally at offices located at
dispersed locations. In addition, they are concerned about the backup window size and data
security with a centralized backup.
To address the organization’s needs and concerns, which deduplication strategy would you
recommend?

When designing a backup solution, what is affected by the recovery point objective (RPO)?

A company performs a full backup on the first Sunday of the month followed by a cumulative
backup on all other Sundays. In addition, they perform an incremental backup each day, that is,
Monday through Saturday.
Tapes are sent offsite for archiving every day at 11 P.M. However, the company experiences a
system crash on the Wednesday of the third week at 2 P.M. This incident requires a full system
restore.
How many backups need to be retrieved in order to perform a restore?

A company is using a backup server and a storage node to back up data. Currently, daily backups
take more than 24 hours to complete. Backup management software analysis indicates that the
physical tape libraries and network are performing fine.
