What is a key advantage of network segmentation?

A key advantage of network segmentation is that it boosts performance. By dividing a larger network into smaller, more manageable segments, network traffic can be optimized. Each segment can handle specific traffic types, reducing congestion and improving overall response times. This is particularly valuable in environments with high volumes of data transmission or where certain applications may require more bandwidth than others.

Segmentation also allows for more efficient use of resources, as it can limit the broadcast domains, thus reducing unnecessary traffic and improving the speed and efficiency of the applications running on the network. Furthermore, with better performance metrics, organizations can ensure that critical services are more reliable and maintain higher levels of user satisfaction.

In contrast, other options either misconstrue the benefits of segmentation or present inaccuracies. For instance, while network segmentation may indeed introduce some complexity to firewall policy management, this is often outweighed by the performance and security benefits it offers. Similarly, segmentation can be both physically implemented (using routers, switches) and logically managed through software solutions, meaning it is versatile rather than limited to a single method. Lastly, though segmentation improves security by isolating sensitive data and workloads, it does not guarantee security; rather, it serves as one layer of a broader security strategy.
