Questions and Answers

When explaining an IPv6 GUA (global unicast address), what would be a good point for the instructor to make?

  • An IPv6 GUA is primarily used for multicast communication.
  • An IPv6 GUA is globally unique and routable on the IPv6 internet. (correct)
  • An IPv6 GUA is automatically assigned to devices by the local router.
  • An IPv6 GUA is only used for local communication within a single network.
  • What are two characteristics of the 2.4GHz channels for implementing a WLAN with multiple APs?

  • 2.4GHz channels are less prone to interference from microwave ovens and Bluetooth devices.
  • 2.4GHz channels have only three non-overlapping channels available (channels 1, 6, and 11). (correct)
  • 2.4GHz channels have better penetration through walls compared to 5GHz channels.
  • 2.4GHz channels have higher data transfer rates compared to 5GHz channels.
  • For accommodating at least 500 subnets from address 172.16.0.0/16, what is an appropriate subnet mask and corresponding number of available host IP addresses per subnet to meet the requirement?

  • $/22$ subnet mask with 1022 available host IP addresses per subnet. (correct)
  • $/24$ subnet mask with 254 available host IP addresses per subnet.
  • $/25$ subnet mask with 126 available host IP addresses per subnet.
  • $/23$ subnet mask with 510 available host IP addresses per subnet.

    Study Notes

    IPv6 GUA

    • A global unicast address is a unique identifier for an IPv6 interface, allowing it to be reached from any other IPv6 interface on the internet.

    WLAN Implementation with Multiple APs

    • The 2.4GHz channels have a characteristic of overlapping channels, which can cause interference between APs.
    • The 2.4GHz channels have a limited number of non-overlapping channels, making it challenging to implement a WLAN with multiple APs.

    Subnetting with 172.16.0.0/16

    • To accommodate at least 500 subnets, an appropriate subnet mask is /22, which provides 1022 available host IP addresses per subnet.
    • The subnet mask /22 allows for 1024 subnets, exceeding the required 500 subnets.

    MAC Address

    • A MAC (Media Access Control) address is a unique identifier assigned to a network interface controller (NIC) for communication at the data link layer.

    Subnet Mask Purpose

    • The purpose of a subnet mask is to determine the scope of a subnet, allowing devices to distinguish between local and remote hosts, and to route packets accordingly.
