200-301 - Network Fundamentals - Section 1.1

Explain the role and function of network components - routers, Layer 2 and Layer 3 switches, next-generation firewalls and IPS, access points, controllers, endpoints, servers, and PoE - and characterise topology architectures.

Identify what each device in a campus network does: routers move packets between subnets, Layer 2 switches forward frames within a VLAN, Layer 3 switches add inter-VLAN routing, and wireless LAN controllers manage lightweight access points. Distinguish two-tier and three-tier campus designs, spine-leaf, WAN, and SOHO topologies, and recognise on-premise versus cloud placement of network services.
