H12-811 Exam - Question 45

VLAN assignment by service type is the most logical method to use when assigning service VLANs during campus network planning. This approach ensures that VLANs are categorized based on the type of service they support, which helps in organizing the network more efficiently and enhances manageability and security. Other methods like assignment by geographic area, logical area, or personnel structure may not align as closely with the specific technical requirements and functions of the services being provided.
