200-301 Question 104
Select 2You are tasked with configuring IPv6 addresses on a network. One of the devices requires an address that is routable across the internet, while another device needs an address that is only valid within a local network segment. A third device requires an address that can communicate within a private network but is not routable on the internet. Which types of IPv6 addresses should you use for these devices, respectively?
- A
Global Unicast for the internet-routable device, Link-Local for the local network segment, Unique Local for the private network
- B
Unique Local for the internet-routable device, Link-Local for the local network segment, Global Unicast for the private network
- C
Global Unicast for the internet-routable device, Unique Local for the private network, Link-Local for the local network segment
- D
Link-Local for the internet-routable device, Unique Local for the private network, Global Unicast for the local network segment
Show answer and explanation
Correct answers: A, C
Explanation
IPv6 addresses are categorized based on their scope and purpose: Global Unicast addresses (2000::/3) are used for internet routing, Link-Local addresses (FE80::/10) are automatically assigned and only valid within a local network segment, and Unique Local addresses (FC00::/7) are private and not routable on the internet. Properly understanding their scope and use is essential for network design and configuration.
- A. Correct.
Correct: Global Unicast addresses are routable on the internet, Link-Local addresses are used for communication within a local segment, and Unique Local addresses are private and not routable on the internet.
- B. Incorrect.
Incorrect: Unique Local addresses are not routable on the internet, so this configuration is invalid for the internet-routable device.
- C. Correct.
Correct: This configuration properly assigns Global Unicast for internet routing, Unique Local for private communication, and Link-Local for local segment communication.
- D. Incorrect.
Incorrect: Link-Local addresses cannot be used for internet communication, and Global Unicast addresses are not restricted to a local network segment.
