Which statements are valid regarding port pairing and forwarding domains? (Choose two.)

The statement that both port pairing and forwarding domains create separate broadcast domains is accurate. In networking, a broadcast domain is defined as a set of devices that can communicate with each other directly via broadcast at the data link layer (Layer 2). When a network is divided into separate broadcast domains, it ensures that broadcast traffic from one domain does not affect others, thereby enhancing performance and security.

Port pairing involves grouping physical interfaces to function as one logical unit. When configured correctly, this can segregate traffic and allow for the creation of distinct broadcast domains. Similarly, forwarding domains can be used to manage traffic flow and segmentation in a network, ensuring that broadcasts stay contained within designated domains.

The idea that forwarding domains only apply to virtual interfaces is incorrect; they can apply to any interface type that is part of a defined forwarding domain. Additionally, while port pairing may focus more on physical interfaces for its function, it does not strictly exclude virtual interfaces.

Thus, when looking at the overall functionality of broadcast domains in relation to port pairing and forwarding, they serve to effectively isolate and manage traffic in different areas of the network. Both can indeed encompass a mix of interface types, making the understanding of these concepts crucial for network segmentation and traffic management.
