  • Understand local area networks (LANs)
    • Perimeter networks; addressing; reserved address ranges for local use (including local loopback IP), VLANs; wired LAN and wireless LAN
  • Understand wide area networks (WANs)
    • Leased lines, dial-up, ISDN, VPN, T1, T3, E1, E3, DSL, cable and more, and their characteristics (speed, availability)
  • Understand wireless networking
    • Types of wireless networking standards and their characteristics (802.11a,b,g,n, including different GHz ranges), types of network security (WPA, WEP, 802.1X and others), point-to-point (P2P) wireless, wireless bridging
  • Understand network topologies and access methods
    • Star, mesh, ring

Understanding Network Hardware (20-25%)

  • Understand switches
    • Transmission speed, number and type of ports, number of uplinks, speed of uplinks, managed or unmanaged switches, VLAN capabilities, Layer 2 and Layer 3 switches and security options, hardware redundancy, support, backplane speed, switching types and MAC table, understand capabilities of hubs versus switches
  • Understand routers
    • Transmission speed considerations, directly connected routes, static routing, dynamic routing (routing protocols), default routes; routing table and how it selects the best route(s); routing table memory, network address translation (NAT), software routing in Windows Server; Quality of Service (QoS)
