Network Devices — CompTIA Network+ (N10-009) Practice Questions
Network devices is a broad topic on the N10-009 exam that covers the purpose, placement, and behavior of hubs, switches, routers, firewalls, access points, and other infrastructure components. Understanding the OSI layer at which each device operates is fundamental, since switches work at Layer 2, routers at Layer 3, and firewalls may operate at multiple layers. The exam also covers specialty devices such as load balancers, proxy servers, content filters, and VPN concentrators. Selecting the correct device for a given scenario and diagnosing faults based on device behavior are common question types.
