200-301 Question 98
Single answerA network engineer is configuring an IPv6 network and needs to assign an address type that allows devices to communicate with other devices on the same local link without requiring a router. Which IPv6 address type should be used?
- 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 in IPv6 (typically starting with FE80::/10) are automatically configured on all IPv6-enabled interfaces and allow devices to communicate with each other on the same local link without requiring a default gateway or router. This makes them essential for local communication scenarios, such as neighbor discovery and device-to-device communication on the same network segment.
- A. Incorrect.
Global Unicast Addresses are routable on the internet and are used for global communication, not for local link communication.
- B. Correct.
Link-Local Addresses are automatically assigned to all IPv6-enabled interfaces and are used for communication between nodes on the same link without requiring a router.
- C. Incorrect.
Unique Local Addresses are similar to private IPv4 addresses and are used for communication within a private network, not specifically for local link communication.
- D. Incorrect.
Multicast Addresses are used to send packets to multiple nodes simultaneously but are not used for local link communication between devices.
