What is the general purpose of network segmentation?

Network segmentation serves multiple purposes, and the option that includes all of its benefits encompasses the reasons why organizations implement this practice.

Firstly, improving speed is significant because segmenting a network reduces the size of collision domains. When traffic is isolated within smaller segments, the amount of broadcast traffic is minimized, which can enhance overall network performance and speed.

Secondly, enhancing security is a critical function of network segmentation. By dividing the network into smaller, manageable segments, organizations can enforce specific security policies for each segment. This limits access to sensitive data and systems, thereby reducing the risk of unauthorized access and potential breaches.

Lastly, reducing collisions is inherently part of segmentation. In a non-segmented network, any device communicating on the network can potentially interfere with others, leading to data collisions that can degrade performance. Segmentation helps mitigate this issue by isolating traffic within distinct segments, ultimately leading to more efficient network operations.

Considering these factors, it becomes clear why understanding network segmentation is vital for both enhancing efficiency and bolstering security within an organization's infrastructure.
