You Are Expecting a Very Important File from a Co-Worker

Multiple Choice

He informs you that he sent the file yesterday, but will send it again immediately. After some time, you still have not received his e-mail message.

B) The attachment's file size exceeds the size limits of the e-mail filter policy.
C) File attachments with an .exe extension may contain malicious code.
D) The file name of the attached file exceeds the file name length of the filter policy.
