Switch forwarding logic dictates that a switch flood broadcasts out all switchports that are in the same what?

The correct answer is that a switch floods broadcasts out all switchports that are in the same VLAN.

In networking, a Virtual Local Area Network (VLAN) is a logical grouping of devices that can communicate with each other as if they were on the same physical network, regardless of their actual location. Switches operate based on the concept of VLANs to manage broadcast traffic. When a switch receives a broadcast frame, it needs to send it out to all devices connected to the network segment (or broadcast domain) to ensure that all relevant devices can respond.

By defining broadcast domains through VLANs, switches ensure that broadcasts do not leak into other segments that should not receive the traffic. This helps to maintain efficient traffic management and minimizes unnecessary load on devices that are not intended to receive those broadcasts. Consequently, all ports within a VLAN will receive the broadcast, while devices in other VLANs will not, allowing for both separation of traffic and efficient communication within the same group of devices.

In contrast, router, bridge domain, and multicast group do not accurately describe the level of separation that determines how switches manage broadcast traffic. Routers typically separate broadcast domains themselves, bridge domains can span across different types of networking devices, and multicast groups relate to a different
