By default, the outgoing mail will be scanned by which one of the following?

Question

Options

• AReputation Filters
• BAnti-Virus
• CAnti-Spam
• DOutbreak Filters

• A
  2% (1)
• B
  92% (57)
• C
  5% (3)
• D
  2% (1)

Explanation

Anti-Virus (B) is correct because, by default on mail security appliances (such as Cisco ESA), outbound mail pipelines enable Anti-Virus scanning to prevent an infected internal host from spreading malware to external recipients - protecting the organization's reputation and downstream systems.

Reputation Filters (A) are wrong because they evaluate the sender's IP reputation and are applied to incoming connections, not outgoing ones - the appliance has no reason to score its own sending reputation on egress.

Anti-Spam (C) is wrong because Anti-Spam is designed for inbound mail; outgoing mail is assumed to originate from authorized senders, so spam scoring is not applied by default on the outbound pipeline.

Outbreak Filters (D) are wrong because Outbreak Filters (which use global threat data to quarantine suspicious messages) are also targeted at incoming threats and are not enabled by default for outbound mail.

Memory tip: Think "You control what goes out, but a sick machine can still spread a virus" - the one outbound protection you keep by default is Anti-Virus, because internal hosts can be compromised without the user knowing.
