What is one benefit of using network segmentation?

Using network segmentation offers significant benefits, particularly in isolating and containing network issues. When a network is segmented, it is divided into smaller, more manageable parts or subnets. This division means that if a problem occurs in one segment—such as a security breach, a malfunction, or excessive traffic—it does not necessarily affect the entire network.

By containing the issue within a specific segment, administrators can troubleshoot, isolate, and resolve the problem more effectively without risking downtime or disruptions to other segments. This helps to maintain overall network performance and security, making it easier to implement measures such as access controls, monitoring, and specific firewall rules tailored to the needs of each segment.

The other choices, while they may imply certain effects of network segmentation, do not capture this critical advantage as effectively. For example, reducing the number of IP addresses and simplifying the physical layout of the network are not primary objectives of segmentation, as segmentation can actually require more addresses within a structured scheme. Streamlining data management may occur as a secondary effect, but is not the main reason for implementing segmentation. Thus, the primary benefit of segmentation lies in its ability to effectively isolate and manage issues within individual segments of the network.
