200-301 Question 103
Single answerYou are configuring IPv6 addresses on a network. A specific address type is needed that can be used for communication within a single link and does not require a global routing prefix. Which of the following IPv6 address types meets this requirement?
- A
Global Unicast Address
- B
Unique Local Address
- C
Link-Local Address
- D
Multicast Address
Show answer and explanation
Correct answer: C
Explanation
Link-Local Addresses are specifically designed for communication between nodes on the same link. They are automatically assigned to every IPv6-enabled interface and use the prefix FE80::/10. Unlike Global Unicast or Unique Local Addresses, Link-Local Addresses do not require a routing prefix and cannot be routed beyond their link.
- A. Incorrect.
Global Unicast Addresses are designed for internet-wide routing and require a global routing prefix. They are not limited to a single link.
- B. Incorrect.
Unique Local Addresses are intended for local communication within a site or organization and can route within that scope, but they are not restricted to a single link.
- C. Correct.
Link-Local Addresses are automatically configured on all IPv6-enabled interfaces and are restricted to communication within a single link. They do not require a global routing prefix.
- D. Incorrect.
Multicast Addresses are used for one-to-many communication, not for single-link communication.
