Refer to the exhibit, which displays a topology diagram. Which two statements describe the built-in bridge functionality on a transparent mode FortiMail? (Choose two.)

Question

Options

• AIf port1. is required to process SMTP traffic, it must be configured as a routed interface.
• BAll bridge member interfaces belong to the same subnet as the management IP.
• CThe management IP is permanently tied to port1, and port1 cannot be removed from the bridge.
• DAny bridge member interface can be removed from the bridge and configured as a routed

• B
  74% (25)
• D

Explanation

In FortiMail's transparent mode, the built-in bridge groups all member interfaces into a single Layer 2 domain, meaning they all share the same subnet as the management IP (B). The management IP is bound specifically to port1 and port1 is a permanent member of the bridge - it cannot be removed, unlike other member interfaces (C).

Why A is wrong: In transparent mode, SMTP traffic is processed by bridge member interfaces without needing to be configured as routed interfaces - that's the whole point of transparent mode (traffic passes through without requiring IP reassignment).

Why D is wrong: While other bridge member interfaces (not port1) can be removed and made into routed interfaces, port1 is the exception - it's permanently tied to the management IP and cannot leave the bridge, making "any" incorrect.

Memory tip: Think of transparent mode FortiMail like a bridge with a fixed anchor - port1 is the anchor (management IP lives there, immovable), all bridge ports share one subnet, and the bridge itself is invisible to the email flow passing through it.
