What is the main purpose of subnetting a network?

• A. To enhance network security
• B. To simplify network management
• C. To divide a large network into smaller, manageable sub-networks
• D. To improve data transmission speed

Answer: (C)

The primary purpose of subnetting a network is to divide a large network into smaller, manageable sub-networks. This segmentation allows for a more efficient use of IP addresses, reduces network congestion, and enhances performance by limiting the broadcast domain. Each subnet can be managed independently, which simplifies troubleshooting and administration. This approach also aids in optimizing network performance and allows for better organization of network resources. By isolating different segments of a network, it becomes easier to control traffic flow and enhance security measures tailored to specific parts of the network. While enhancing security, simplifying management, and improving speed are important aspects of network administration, these benefits are secondary to the fundamental goal of creating well-defined, smaller subnetworks that can be monitored and managed more effectively.
