ITN Section 8.3 Quiz: IPv6 Addressing Answers Cisco 2019 100%

This quiz covers the content in CCNA R&S Introduction to Networks Section 8.2. It is designed to provide an additional opportunity to practice the skills and knowledge presented in the chapter and to prepare for the Chapter Exam.

  1. What type of address is automatically assigned to an interface when IPv6 is enabled on that interface?

    • global unicast
    • link-local
    • loopback
    • unique local
  2. Fill in the blank.

    Consider the following range of addresses:
    2001:0DB8:BC15:0600:: to 2001:0DB8:BC15:0FFF::

    The prefix length for the range of addresses is       52        .

    • Noted: There are 2 possible answers. You can fill in one of the following in netacad: 52, or /52. But you can fill only 52 in our system.

      Explanation:

      All the addresses have the part 2001:0DB8:BC15:0 in common. Each number or letter in the address represents 4 bits, so the prefix is /52.
  3. What is the interface ID of the IPv6 address 2001:DB8::1000:A9CD:47FF:FE57:FE94/64?

    • FE94
    • FE57:FE94
    • 47FF:FE57:FE94
    • A9CD:47FF:FE57:FE94
    • 1000:A9CD:47FF:FE57:FE94
      Explanation:

      The interface ID of an IPv6 address is the rightmost 64 bits, or last four hextets, of the address if no interface ID bits have been used for subnets.
  4. Which IPv6 network prefix is only intended for local links and can not be routed?

    • 2001::/3
    • FC00::/7
    • FE80::/10
    • FEC0::/10
      Explanation:

      FE80::/10 is a link-local prefix. Devices with only link-local addresses can communicate with other devices on the same network but not with devices on any other network.
  5. Refer to the exhibit. What is the global IPv6 address of the host in uncompressed format?

    • 2001:0DB8:0000:0000:0BAF:0000:3F57:FE94
      Explanation:

      In the compressed format, the :: represents two contiguous hextets of all zeros. Leading zeros in the second, fifth, and sixth hextets have also been removed.
