Virtual local area network (VLAN)
Implemented on network switches in a LAN as a way of logically grouping users and resources in a broadcast domain. Often, such VLANs correlate to department functions (such as Accounting, Sales, and Research & Development) and/ or IP subnets. VLANs provide scalability, segmentation, and (some) security at Layer 2 and can also work to limit the size of your Ethernet broadcast domains. VLANs are implemented by using Institute of Electrical and Electronics Engineers (IEEE) 802.1q tagging to tag Ethernet frames with VLAN information. Note: the IEEE is an international organization that defines many standards, including numerous 802 networking standards.
The indexed versions don't agree on this one
This question appears on 5 CBT versions we've indexed, and they don't all give the same answer. Exam editions change and answer keys get re-cut, so more than one of these was correct on the test it came from. Here is each of them, and how many versions give it.
A switch that can be configured via a command-line interface and sometimes can be configured in groups. Usually, they are assigned their own IP addresses. VLANs can only be implemented through managed switches.
