Guide on Virtual Local Area Networks (VLANs)
What is Virtual Local Area Networks (VLANs):
VLANs are a network construct that separates an existing physical network into multiple logical networks. They allow devices in different geographical areas to be grouped into identical broadcast domains.
Importance of VLANs:
VLANs increase the network's performance and security, restrict broadcasts, enforce business needs and access policies, and simplify network management. They are crucial in network design as they allow for logical segmentation of networks regardless of the physical location.
How it works:
Network admins can configure VLANs through software rather than manually moving cables or devices. Devices in the same VLAN communicate as if they are attached to the same broadcast domain, regardless of their physical location.
Exam Tips: Answering questions on VLANs:
Understand the principles of VLAN operation, its benefits, and how to implement and manage them on a network. A comprehensive grasp of trunking protocols like VLAN Trunking Protocol (VTP), Inter-VLAN routing, and IEEE 802.1Q, an important VLAN standard, is critical. Remember that each VLAN operates in its own domain and that communication between VLANs requires a layer 3 device.
Always refer to real-world applications whenever possible, as context can be valuable to nail tricks questions or case-based scenarios.

Virtual Local Area Networks (VLANs) practice test
A Virtual Local Area Network (VLAN) is a logical sub-network that groups devices on one or more LANs by logically segmenting them based on specific network criteria. VLANs help improve performance and security by reducing the broadcast domain and allowing network administrators to organize devices or users according to their requirements or access privileges. VLANs are configured using network switches, which enforce the segmentation rules and allow or restrict data traffic between devices based on their assigned VLAN. VLANs can be assigned to users based on defined criteria, such as their physical location, department, or function within a company. Network+ Certification exam covers various aspects of VLANs, including their configuration, management, and troubleshooting.
