    Question

    In networking, what is the primary purpose of

    subnetting?
    A To increase the size of IP address space. Correct Answer Incorrect Answer
    B To divide a network into smaller, more manageable segments Correct Answer Incorrect Answer
    C To reduce latency in data transmission Correct Answer Incorrect Answer
    D To improve security by encrypting data packets Correct Answer Incorrect Answer
    E To establish direct peer-to-peer connections between devices Correct Answer Incorrect Answer

    Solution

    Subnetting involves dividing a larger IP network into smaller, subnetworks (subnets) to improve network efficiency and management. Each subnet functions as an independent network, enabling better control over traffic flow and addressing. Benefits of subnetting include:

    • Efficient IP Utilization : By allocating IP addresses to subnets based on size, subnetting minimizes wastage.
    • Enhanced Security : Subnets can isolate sensitive parts of a network.
    • Traffic Management : Reduces congestion by localizing traffic within subnets.
    • Simplified Administration : Smaller networks are easier to monitor and manage.
    For example, in an organization with multiple departments, subnetting can create separate subnets for each department, ensuring that traffic remains localized and improving overall performance. Explanation of Incorrect Options: A) To increase the size of IP address space : Subnetting does not increase IP space; it optimizes the use of existing space within a network. C) To reduce latency in data transmission : While subnetting can improve performance, its primary purpose is segmentation, not latency reduction. D) To improve security by encrypting data packets : Encryption is unrelated to subnetting. Subnetting can enhance security but does not involve encryption directly. E) To establish direct peer-to-peer connections between devices : Subnetting organizes networks but does not establish direct device connections. This is a characteristic of protocols like P2P.
