What do subnets and VLANs primarily separate?

Subnets and VLANs primarily separate broadcast and security domains.

Subnets are segments of a larger network that allow for the efficient routing of data by dividing a network into smaller, more manageable pieces. Each subnet has its own network address, which helps to control traffic and reduce unnecessary broadcast traffic, as devices in different subnets do not receive broadcast packets addressed to a different subnet.

VLANs (Virtual Local Area Networks) create logical groupings of devices within the same physical network, allowing for segmentation based on user groups, departments, or functions, rather than physical location. This segmentation also helps minimize broadcast traffic and enhances security by isolating devices from each other even if they are on the same physical network infrastructure.

Both subnets and VLANs help manage network performance by containing broadcast traffic and by creating isolated environments that enhance security. For instance, sensitive data traffic can be placed on its own VLAN, ensuring that it is not accessible to general users, thus creating a more secure environment.

Traffic and data integrity, while important concepts, are not the primary focus of what subnets and VLANsachieve. Active and passive devices, as well as public and private networks, describe different aspects of network functionality but do not encapsulate the specific role of
