VLANs can be assigned based on service types during campus network planning.

In modern campus network planning, assigning VLANs based on service type is a fundamental design principle. This method involves creating separate logical networks (VLANs) for different types of traffic, such as data, voice (VoIP), video surveillance, and network management. This segmentation allows network administrators to apply specific Quality of Service (QoS) policies, security controls (e.g., Access Control Lists), and traffic management rules to each service, optimizing performance and enhancing security. For example, voice traffic can be placed in a high-priority VLAN to ensure low latency.

This is a True/False question. The statement is factually correct according to established network design best practices. There is no "False" case under standard design methodologies.

The material explicitly discusses assigning VLANs based on criteria such as port, MAC address, and IP subnet, which are often correlated with service types for policy application.
