Why is network segmentation recommended in larger networks?

• A. To limit access to external networks
• B. To simplify network administration
• C. To prevent external attacks
• D. To enhance performance and security

Answer: (D)

Network segmentation is recommended in larger networks primarily to enhance performance and security. By dividing a network into smaller, manageable segments or subnetworks, organizations can effectively control traffic flow, reduce congestion, and isolate sensitive data. This practice allows for efficient utilization of network resources and enhances overall performance by minimizing latency caused by unnecessary network traffic. In terms of security, segmentation limits the spread of potential breaches. If one segment is compromised, the threat can often be contained within that segment, preventing it from spreading to the entire network. Additionally, different security policies can be applied to various segments based on their requirements, further enhancing the overall security posture. The concept of segmentation is particularly beneficial in larger networks where the complexity and volume of traffic can lead to challenges in performance and security management. As such, maintaining segmented networks contributes significantly to the resilience and efficiency of larger organizational infrastructures.
