Which of the following products verifies that files received by an SMTP server do not contain any suspicious code?
  1. IDS
  2. Web virus filter
  3. Packet filter firewall
  4. E-mail virus filter
Explanation
Answer - D - An e-mail virus filter verifies that files received by an SMTP server contain no suspicious files.

Key Takeaway: SMTP is the primary protocol used in e-mail. An SMTP virus filter checks all incoming and outgoing e-mails for suspicious code. If a file is potentially infected, the scanner notifies the originator and quarantines the file. Nip them in the bud!
