A network technician wants to create efficiencies in network traffic by implementing a device which applies microsegmentation by establishing a point-to-point link between any two network nodes. Which of the following should they implement?

The most appropriate choice for implementing microsegmentation through a point-to-point link between two network nodes is a Layer 2 switch. Layer 2 switches operate at the data link layer and are responsible for forwarding data based on MAC (Media Access Control) addresses. By utilizing a Layer 2 switch, the network technician can create separate collision domains for each connected device, allowing for more efficient traffic management and minimizing the possibility of packet collisions.

This segmentation ensures that traffic between devices does not interfere with other traffic on the network, significantly improving overall performance and security. Layer 2 switches support VLANs (Virtual Local Area Networks), which are essential for creating logically separated networks within the same physical infrastructure, enhancing both performance and security.

In contrast, routers function at Layer 3 and are used for directing traffic between different networks rather than for creating microsegmented environments within a single network. Hubs, on the other hand, broadcast all incoming traffic to all ports, which does not create any form of segmentation or efficiency. Firewalls serve to control access and protect the network from unauthorized access or threats, but they do not specifically address the need for microsegmentation in the context of point-to-point networking between nodes.

Therefore, the Layer 2 switch
