What is the MAIN drawback of e-mailing password-protected zip files across the Internet? They:
A.
all use weak encryption.
B.
are decrypted by the firewall.
C.
may be quarantined by mail filters.
D.
may be corrupted by the receiving mail server.
Explanation:
Often, mail filters will quarantine zip files that are password-protected since the filter (or the
firewall) is unable to determine if the file contains malicious code. Many zip file products are
capable of using strong encryption. Such files are not normally corrupted by the sending mail
server.
