NSE4 · Question #32
Which statements are correct for port pairing and forwarding domains? (Choose two.)
The correct answer is A. They both create separate broadcast domains. D. They may contain physical and/or virtual interfaces. Both port pairing, used in transparent mode, and forwarding domains are mechanisms to segment networks by creating separate Layer 2 broadcast domains, and they can both incorporate physical and/or virtual interfaces.

Why each option
Both port pairing, used in transparent mode, and forwarding domains are mechanisms to segment networks by creating separate Layer 2 broadcast domains, and they can both incorporate physical and/or virtual interfaces.
In transparent mode, port pairing links two interfaces to form a Layer 2 bridge, effectively creating a separate broadcast domain, while forwarding domains explicitly define isolated Layer 2 broadcast domains within the FortiGate.
While port pairing is commonly associated with physical interfaces, the general concept of interface grouping and forwarding domains can encompass virtual interfaces as well.
Forwarding domains are not limited to virtual interfaces; they can be configured on both physical and virtual interfaces for Layer 2 segmentation.
Forwarding domains can include both physical interfaces (e.g., hardware ports) and virtual interfaces (e.g., VLAN sub-interfaces, software switch members), offering flexible Layer 2 segmentation.
