How does network segmentation improve management?

Network segmentation enhances management primarily by making larger networks more manageable. When a network is segmented, it is divided into smaller, more manageable sections or segments. This segmentation allows for easier monitoring and control of data traffic within each segment, thereby improving the performance and security of the overall network.

Additionally, it simplifies troubleshooting because issues can be isolated and identified within a smaller segment, rather than having to sift through a vast array of data from the entire network. Each segment can also have tailored security policies and management protocols, providing administrators with greater flexibility and control.

The other choices talk about different aspects that don't directly relate to effective network management. For example, reducing the number of users on the network doesn’t inherently improve management; it may actually limit the usability of the network. Eliminating the need for routers can misrepresent the role of routers in network architecture, which often serve critical functions even in segmented networks. Lastly, combining all network traffic into one stream would likely complicate management, rather than simplify it. Overall, segmentation is a strategic approach to enhance efficiency and control in larger networks.
