Securing Email with Cisco Email Security Appliance (SESA) — Question 85

A network engineer must tighten up the SPAM control policy of an organization due to a recent SPAM attack. In which scenario does enabling regional scanning improve security for this organization?

Answer options

• A. when most of the received email originates outside of the U.S.
• B. when most of the received email originates from a specific region
• C. when most of the received spam originates outside of the U.S.
• D. when most of the received spam comes from a specific country

Correct answer: B

Explanation

Enabling regional scanning is most effective when most emails are received from a particular area, as it allows for more focused filtering based on known spam characteristics of that region. Options A and C are incorrect since they refer to email and spam coming from outside the U.S., which doesn't leverage regional scanning effectively. Option D is also incorrect as it specifies a single country but not a broader region.
