  • Question

  • Which of the following is true when describing a unique local address?


  • Options
  • A. Packets addressed to a unicast address are delivered to a single interface.
  • B. These are your typical publicly routable addresses, just like a regular publicly routable address in IPv4.
  • C. These are like private addresses in IPv4 in that they are not meant to be routed.
  • D. These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap.

  • Correct Answer
  • These addresses are meant for nonrouting purposes, but they are almost globally unique so it is unlikely they will have an address overlap. 

    Explanation
    These addresses are meant for nonrouting purposes like link-local, but they are almost globally unique so it is unlikely they will have an address overlap. Unique local addresses were designed as a replacement for site-local addresses.
