You need to add a device to the network that will allow you to create virtual local area networks (VLANs). What device should you use?

To create virtual local area networks (VLANs), the most appropriate device is a managed switch. A managed switch offers advanced features that enable network administrators to segment a physical network into multiple logical networks, known as VLANs. By using VLANs, you can separate different types of traffic within the same physical infrastructure, improving security and reducing broadcast domains.

Managed switches provide a user interface (often through a web portal or console) for configuration and management, allowing for tasks such as assigning ports to specific VLANs, configuring inter-VLAN routing, and applying security policies. This level of control is essential for efficiently managing network traffic and ensuring robust network design.

On the other hand, unmanaged switches do not offer the ability to create VLANs as they lack management features; they work with a flat network topology and cannot separate traffic. Routers can handle inter-VLAN routing but are not primarily used for creating VLANs. Hubs do not support VLANs at all, as they operate at the physical layer and simply forward packets to all connected devices without any filtering or management. Therefore, a managed switch is the proper choice for setting up VLANs effectively.
