VLAN Certification
About VLAN
A VLAN (Virtual Local Area Network) is a logical grouping of devices on a network, regardless of their physical location. VLANs allow network administrators to segment and isolate devices on a LAN (Local Area Network) based on specific business needs, such as departmental or security requirements.
By creating VLANs, network administrators can create multiple virtual networks on a single physical infrastructure, which can increase security, reduce network congestion, and improve network performance. For example, a VLAN can be created for the finance department, while another VLAN can be created for the marketing department, this way those VLANs can be configured with different security policies, and access controls, without affecting the other VLANs.
VLANs are configured using VLAN tagging, which is a method of adding a VLAN identifier to the packet header. This allows network devices to identify the VLAN to which a packet belongs and route it accordingly. VLANs are typically used in enterprise networks, but also can be used in smaller networks as well.
Who should take the VLAN Certification exam?
VLAN (Virtual LAN) course is suitable for:
Network administrators and engineers.
IT professionals involved in network design and implementation.
Students studying computer networking or information technology.
Business professionals involved in network operations and management.
Anyone interested in learning about VLANs, a network design and implementation technology used to segment networks into smaller, more manageable sub-networks.
VLAN Certification Course Outline
A VLAN (Virtual Local Area Network) is a logical grouping of devices on a network that allows for the segmentation of broadcast domains. This can improve network security and performance by isolating different groups of devices and controlling the flow of traffic between them.
Some topics that may be covered in a course on VLANs include:
Basic concepts of VLANs and how they are used in network design
Configuring and managing VLANs on different types of network devices (such as switches and routers)
Understanding VLAN tagging (802.1Q) and how it is used to identify VLANs on a network
Implementing VLAN security measures, such as private VLANs and port security
Inter-VLAN routing and the use of VLAN trunking to connect different VLANs
Troubleshooting and monitoring VLANs
Understanding the VLANs standards like IEEE 802.1Q and IEEE 802.1ad
Understanding the concepts of VLANs in Software Defined Networking
