Which of the following is the MOST robust method for disposing of magnetic media that contains
confidential information?

A.
Degaussing

B.
Defragmenting

C.
Erasing

D.
Destroying

Explanation:
Destroying magnetic media is the only way to assure that confidential information cannot be
recovered. Degaussing or demagnetizing is not sufficient to fully erase information from magnetic
mediA. The purpose of defragmentation is to eliminate fragmentation in file systems and does not
remove information. Erasing or deleting magnetic media does not remove the information; this
method simply changes a file’s indexing information.
