What does the command set forward-domain <domain_ID> in a transparent VDOM interface do?

The correct answer is B. It isolates traffic within a specific VLAN by assigning a broadcast domain to an interface based. In a transparent mode Virtual Domain (VDOM) configuration, FortiGate operates as a Layer 2 bridge rather than performing Layer 3 routing.

Explanation

In a transparent mode Virtual Domain (VDOM) configuration, FortiGate operates as a Layer 2 bridge rather than performing Layer 3 routing. The set forward-domain <domain_ID> command is used to control how traffic is forwarded between interfaces within the same transparent VDOM. A forward-domain acts as a broadcast domain, meaning only interfaces with the same forward- domain ID can exchange traffic. This setting is commonly used to separate different VLANs or network segments within the transparent VDOM while still allowing FortiGate to apply security
