Question

What is the purpose of subnetting?

• A. To convert IPv4 addresses into IPv6
• B. To encrypt network communication
• C. To reduce network congestion and improve efficiency
• D. To multicast Packets

Hint:

Subnetting is like dividing a large office building (a network) into smaller departments (subnets). This way, announcements for the sales department don't disturb the engineering department, reducing overall noise (congestion).

Answer 1

The Correct Option is C

Subnetting is the process of dividing a single large network into multiple smaller, logical sub-networks (subnets).
The primary purposes and benefits of subnetting are:
1. Reduced Network Traffic: By dividing a network, broadcast traffic is confined to its own subnet. A broadcast message sent on one subnet is not forwarded to other subnets, which reduces overall network congestion. 2. Improved Network Performance: The reduction in broadcast traffic and the logical grouping of hosts improve the overall efficiency and performance of the network. 3. Simplified Management: Smaller networks are easier to manage and troubleshoot. 4. Improved Security: Network administrators can implement security policies to control traffic between different subnets.
Looking at the options, (C) best summarizes these key benefits. Subnetting helps to organize a network logically, which in turn reduces congestion (broadcast traffic) and improves overall efficiency.
