A. B. C. D.B.
The correct answer is B. VLANs.
VLANs (Virtual Local Area Networks) are a network segmentation technology that allows multiple logical subnets to coexist on the same physical network infrastructure. VLANs enable the network administrator to group network devices, regardless of their physical location, into logical groups.
With VLANs, a switch can divide a physical network into multiple virtual networks by assigning different ports to different VLANs. Devices on different VLANs can communicate with each other if the network administrator configures VLAN routing or a layer 3 switch that can route traffic between VLANs.
Each VLAN has its own broadcast domain, which reduces network congestion and improves network performance by reducing the number of devices that receive unnecessary network traffic.
In summary, VLANs are a way to create multiple logical networks within a physical network infrastructure. This allows network administrators to manage and control network traffic more efficiently and securely, while also providing flexibility in network design and implementation.
