What is the purpose of network segmentation?

• A. To increase internet speeds for all users
• B. Dividing a network to improve security and performance
• C. To allow for easier network configuration
• D. To enhance the aesthetics of network layouts

Answer: (B)

The purpose of network segmentation is to divide a network into smaller, more manageable parts, which in turn improves both security and performance. By isolating different sections of the network, organizations can limit the potential spread of attacks and reduce the risk of unauthorized access. For instance, if one segment is compromised, the threat can be contained and does not automatically affect the entire network.

Moreover, segmentation can enhance performance by reducing congestion and optimizing traffic flow. Each segment can operate with its own set of policies and resource allocation, leading to better overall functionality and efficiency. This approach allows for finer control over network resources, enabling quicker responses to issues and tailored configurations that align with specific requirements, all while maintaining overall security.
