Which of the following items should not be retained in an E-mail directory?

A.
Drafts of documents.

B.
Copies of documents.

C.
Permanent records.

D.
Temporary documents.

Explanation:
This is another matter of common sense; the CISSP exam has many situations like this. It is not a
good practice to have Permanent documents in your e-mail, this is because you don’t know if your email is always backed up, and maybe the document must be available in a corporate repository.
There is no problem to have Copies, draft or temporary documents in your email. The important
ones for the company are the Permanent documents.
