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.
