A Virtual LAN is basically a group of IPs on the same subnet. In other words you would link 2 switches from different locations like it's on the same LAN. A LAN is just a local network that consist of local clients only. The method of linking to VLANs together is called Truncking 802.1Q

What are the function of VLAN?
VLANs (Virtual Local Area Networks) segment a physical network into multiple logical networks, enhancing security and reducing broadcast traffic. They allow devices on different VLANs to communicate as if they are on the same local network, despite being physically separated. VLANs also simplify network management by organizing devices based on function or department, making it easier to apply policies and manage resources. Additionally, they enhance overall network performance by isolating traffic.
Can cisco layer 2 support vlan?
Yes, Cisco Layer 2 switches support VLANs (Virtual Local Area Networks). VLANs allow network segmentation by creating separate broadcast domains within the same physical network infrastructure. This capability enhances network performance and security by isolating traffic among different groups of users or devices. Cisco's implementation of VLANs follows the IEEE 802.1Q standard, enabling the tagging of Ethernet frames for proper routing between VLANs.
What is a best practice for VLAN design?
Local VLANs should not extend beyond the distribution layer.
What are the two ways to logically segment a network?
The two primary ways to logically segment a network are through Virtual Local Area Networks (VLANs) and subnetting. VLANs allow for the creation of distinct broadcast domains within a single physical network, enabling better traffic management and security. Subnetting involves dividing a larger IP network into smaller, manageable sub-networks, which enhances performance and improves organization by isolating network traffic. Together, these methods help in optimizing network efficiency and security.
A local area network for a building?
Since local area networks are small in size and geographic location, a building may contain several LANs connected together with routers. It is very common to have many LANs within a building, either as true physical LANs or logical VLANs through managed switches.
Where do you create VLAN and what for it is used?
VLANs (Virtual Local Area Networks) are created on network switches, specifically through their management interfaces, which can be accessed via web interfaces, command-line interfaces, or network management software. VLANs are used to segment a physical network into multiple logical networks, improving security and reducing broadcast traffic by isolating devices within the same physical infrastructure based on functional or departmental requirements. This segmentation enhances network performance and simplifies network management by allowing different policies and configurations for each VLAN.

What is traditional inter vlan routing?
Traditional inter-VLAN routing involves using a router to enable communication between different VLANs (Virtual Local Area Networks). Each VLAN is assigned its own subnet, and the router interfaces with each VLAN through sub-interfaces or physical interfaces. This method allows for the separation of broadcast domains while facilitating inter-VLAN traffic, enhancing network performance and security. Typically, this approach requires a router or a Layer 3 switch to manage the routing process.
What is the definition of VLAN?
Virtual local-area networks (VLANs) are a switching technology used to improve network performance by separating large broadcast domains into smaller ones.(quote from CCNA 640-802 Exam Topics)The abbreviation VLAN stands for "Virtual Local Area Network". A VLAN is used to segment a physical network into several logical networks which do not interfere with eachother, even though the data might be traveling on the same physical wires.
What are the categories of a network?
Networks can be categorized based on various criteria, including their scale, topology, and purpose. Common types include local area networks (LANs), wide area networks (WANs), and metropolitan area networks (MANs), which differ primarily in geographical coverage. Additionally, networks can be classified by topology, such as star, ring, bus, or mesh, which describes the arrangement of nodes. Finally, networks can also be categorized by their intended use, such as corporate networks, academic networks, or social networks.
What is network isolation?
Network isolation is a security measure that separates a network or specific devices within a network from other networks to prevent unauthorized access and limit the spread of potential threats. This can be achieved through various methods, such as firewalls, VLANs (Virtual Local Area Networks), or air-gapping, which physically separates networks. By isolating sensitive data and critical systems, organizations can enhance their security posture and reduce the risk of data breaches and cyberattacks.
Wide-area networks contain many local area networks?
Wide area networks can consist of many local area networks, but it is possible for a wide area network to be a single network.
