350-701 Question #399: Real Exam Question with Answer & Explanation

Question

An engineer is configuring Cisco Secure Email Gateway and needs to enable a separated email transfer flow from the Internet and from the LAN. Which deployment mode must be used to accomplish this goal?

Options

• Asingle interface
• Bmulti-context
• Ctransparent
• Dtwo-interface

Explanation

To enable a separated email transfer flow from the Internet and the LAN on a Cisco Secure Email Gateway, the two-interface deployment mode must be used.

Common mistakes.

• A. Single interface mode processes both external and internal email traffic through a single network interface, which does not provide a separated email transfer flow.
• B. Multi-context mode is a feature found in firewalls (like Cisco ASA) that allows multiple virtual firewalls to run on a single physical device, not a deployment mode for an email gateway to separate mail flows.
• C. Transparent mode, often used for firewalls, allows a device to operate without an IP address in the network path, but it does not specifically define how an email gateway separates internet and LAN mail flows as 'two-interface' mode does.
