Explore the OSI model from layer one to layer three, examining modems, hubs, switches, wireless access points, multilayer switches, and routers.
Identify firewalls, intrusion detection and prevention systems, and a VPN concentrator delivering SSL VPN and IPsec encryption, plus load balancers, content switches, and proxy servers to improve performance.
Brian Farrell explains how the PSTN underpins WAN technology and when you lease lines. He covers dial-up, ISDN with PRI and BRI, and DSLs, plus broadband cable and fibre options.
Compare GSM and CDMA wide area network connections, then explore 4G technologies such as LTE and WiMAX, and conclude with satellite WAN links and COMSAT orbit basics.
Explore metro ethernet WAN connections. Review leased line connections, multi-link PGP, and common standards such as T1/T3, E1/E3, OC lines, and DWDM/SDH multiplexing.
Compare circuit-switched and packet-switched networks, examine frame relay versus asynchronous transfer mode, and conclude with a look at multiprotocol label switching for scalable, protocol-independent traffic control.
Explore VPN basics, including site-to-site, remote access, and host-to-host types, with IPsec, AH, ESP, TLS/SSL, and transport and tunnel modes.
Analyze network access services, including the network interface controller at layer 2 with MAC addresses, Radius and TACACS+ authentication, ARIA's remote access, web services, and unified voice services for VoIP.
Explore static versus dynamic IP addressing, and learn how the DHCP server automates IP configuration. Understand the DHCP process—discover, offer, request, and ack—plus scope, reservations, leases, and relay functionality.
Learn how the domain name system maps hostnames to IPs via local, root, and TLD servers, handling authoritative and non-authoritative responses, with A/AAAA, CNAME, PTR, and RMS records, dynamic DNS.
Explore how network address translation conserves IPv4 space by translating private inside local addresses to public inside global addresses, including NAT, static NAT, dynamic NAT, and PAT.
Explore twisted pair cabling, including UTP and shielded types, EMI and crosstalk reduction, connectors like RJ 11 and RJ 45, and Cat three to Cat six with distance limits.
Explore coaxial cabling basics, including RG-58, RG-59, and RG-6, and fiber optic cabling, featuring multimode and single-mode fibers and various connectors such as bayonet types.
Explore media converters for interconnecting fiber and copper cabling, and review essential tools—shrimpers, wire strippers, punch down tools, cable testers, TDRs and OTDRs—plus buying tips.
