    Study Notes

    IPsec and Network Protocols

    • Encapsulating Security Payload (ESP): Provides both authentication and encryption in IPsec.
    • Firewalls filter traffic primarily based on protocols and ports.

    Network Connections

    • Use full duplex connections for simultaneous data transmission on network adapters connecting to switches.
    • T1 line offers a maximum throughput of 1.544 Mbps.

    VPN and Leased Lines

    • Site-to-Site VPNs are ideal for connecting two companies collaborating on a project.
    • Examples of leased lines include DSL.

    Wireless Standards

    • 802.11ac routers are compatible with 802.11n (300 Mbps at 2.4/5 GHz) and 802.11a (54 Mbps at 5 GHz).

    Wireless Networking Tools

    • A wireless bridge connects different wireless networks, such as 802.11a, 802.11g, and 802.11n.

    Network Topologies

    • Ring topology connects computers in a circular layout.
    • Mesh topology connects every computer directly to every other computer.
    • Switch creates separate collision domains, allowing full duplex operations without collisions.

    Server Roles and Network Cables

    • Remote Access role on Windows Server 2016 enables routing.
    • Single-mode fiber cables support the longest signal distances.

    IP Addressing and Subnetting

    • Use ipconfig /all to find a computer's MAC address.
    • For 750 computers, a Class B IP address is recommended.
    • A Class C network's subnet mask for 192.168.1.0 is 255.255.255.0.

    IPv6 and Network Addresses

    • Implement a multicast address for distributing packets to a group of IPv6 interfaces.
    • The local loopback address in IPv6 is ::1.

    Name Resolution

    • LMHOSTS file resolves NetBIOS names to IP addresses.

    VPNs and Security Protocols

    • A VPN creates a private tunnel over public networks.
    • Several tunneling protocols include PPTP, L2TP, and SSTP.

    Ethernet and Port Specifications

    • Ethernet operates on Layer 1 of the OSI model.
    • Cat5 supports speeds of 100 Mbps, while Cat5e supports 1 Gbps.
    • Unsecured websites typically use port 80, while secured ones use port 443.

    Classful Addressing

    • Class A example IP: 100.100.1.1; Class B example IP: 170.100.1.5; Class C example IP: 198.126.1.55; Class D example IP: 244.0.0.2.

    DNS and IP Configuration Commands

    • AAAA records map hostnames to IPv6 addresses.
    • Commands related to IP address management include:
      • ipconfig /release to delete an IP address.
      • ipconfig /renew to acquire an IP address from DHCP.
      • ipconfig /displaydns to show DNS cache.
      • ipconfig /flushdns to purged DNS cache.

    Tracing and Network Statistics

    • tracert is used to trace the path of IP packets across a network.
    • Use pathping to find packet loss statistics.
    • netstat -a displays all listening and established ports, while netstat -p tcp shows info for TCP connections.

    Routing Protocols

    • RIP routing uses hop counts for route calculation, with a maximum of 15 hops.
