QUESTION 5
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.    20
B.    37.5
C.    62.5
D.    80

Answer: C
