200-301 Question 97
Single answerA network administrator is configuring an IPv6 network and needs to assign an appropriate IPv6 address type for devices that should communicate within the same local link but not route traffic beyond it. Which IPv6 address type should the administrator use?
- A
Global Unicast Address
- B
Link-Local Address
- C
Unique Local Address
- D
Multicast Address
Show answer and explanation
Correct answer: B
Explanation
Link-Local Addresses (starting with FE80::/10) are used for communication between devices within the same local link. They are automatically configured on all IPv6-enabled interfaces and are not routable beyond the local link. This makes them the appropriate choice for communication restricted to the same link.
- A. Incorrect.
Global Unicast Addresses are routable across the internet and not restricted to local communication, so this is not suitable for link-local communication.
- B. Correct.
Link-Local Addresses are designed for communication between nodes on the same link and are automatically configured on all IPv6-enabled interfaces. This is the correct answer.
- C. Incorrect.
Unique Local Addresses are intended for local communication within a site or between a small number of sites but are not limited to the same link. Thus, this is not the correct choice.
- D. Incorrect.
Multicast Addresses are used to send packets to multiple devices in a group simultaneously, but they are not limited to communication within the same link.
