Vlan — CompTIA Network+ (N10-009) Practice Questions
A VLAN (Virtual Local Area Network) is a logical segmentation of a physical switch into multiple broadcast domains, and it is a heavily tested concept on the N10-009 exam. VLANs improve security by isolating traffic between departments or device groups, and they reduce unnecessary broadcast traffic across large flat networks. The exam covers how VLANs are assigned to switch ports, how inter-VLAN routing is achieved through a Layer 3 device or router-on-a-stick configuration, and how VLAN misconfigurations contribute to connectivity problems.
