Rewritable and erasable (CDR/W) optical disk are sometimes used for backups that require short
time storage for changeable data, but require?

A.
Faster file access than tape.

B.
Slower file access than tape.

C.
Slower file access than drive.

D.
Slower file access than scale.

Explanation:
This is true, when we use optical media like CD´s to make our backups we need a constant
throughput on the file access and data transfer inside the disk because of the risk to get a buffer
overrun error in the CD writer. If the buffer user by the CD burner is empty and the Hard disk does
not provide data for that time, the Backup will be unsuccessful. This can be solved with a Technology
known as “Burn Proof”.
