    Study Notes

    IPv6 Addresses

    • FC00::/7: Unique Local Address block for IPv6 addressing
    • FE80::/10: Link-local address block used for communications within a local subnet
    • FF00::/8: Used for IPv6 multicast addressing

    Late Collisions on Ethernet

    • Occurs when Carrier Sense Multiple Access/Collision Detection (CSMA/CD) is used
    • Occurs when one side of the connection is configured for half-duplex

    Frame Flooding

    • Frames are sent to every port on the switch in the same VLAN except from the originating port

    Private IPv4 Addresses

    • Allows multiple companies to use the same addresses without conflicts
    • Used for communication between devices within an organization

    Collapsed Core Architecture

    • Enforces routing policies
    • Ideal for smaller organizations looking to reduce costs

    Layer 3 Devices

    • Forward traffic between different networks

    Three-Tier Architecture

    • Provides uninterrupted forwarding service
    • Ensures that the network is scalable and reliable

    IPv6 Address Compression

    • 2001:0EB8:00C1:2200:0001:0000:0000:0331/64 can be compressed to 2001:EB8:C1:22:1::331/64

    Network Appliances

    • Firewalls check the state of a packet to determine its legitimacy

    Access Points

    • Connect wireless devices to a wired network

    Collapsed Core Architecture

    • Ideal for smaller organizations looking to reduce costs
    • Eliminates the need for a complex and expensive core layer
