What is the purpose of network segmentation?

• A. To combine all resources for easier access
• B. To divide a network into smaller, manageable parts for better security
• C. To eliminate the need for firewalls
• D. To enhance hardware performance only

Answer: (B)

The purpose of network segmentation is to divide a network into smaller, manageable parts for better security. This practice helps in isolating sections of the network, which can prevent unauthorized access and limit the potential damage of breaches. By segmenting the network, organizations can apply security controls specific to different segments, effectively creating a layered security approach.

This practice also enhances monitoring and management, as administrators can more easily identify and respond to suspicious activities within specific segments instead of sifting through the entire network. Moreover, segmentation can improve overall network performance since it reduces congestion by limiting broadcast traffic within individual segments.

In contrast, combining all resources for easier access does not enhance security and could potentially expose the entire network to risks. Eliminating the need for firewalls ignores the critical role firewalls play in network protection, while focusing solely on hardware performance overlooks the fundamental security benefits that segmentation provides.
