CCDE: Cisco Certified Design Expert (Practical) — Question 151

Company XYZ has a new network based on IPv6. Some of the subnets that they are planning to use will be confidential and need an addressing scheme that confines them to the local campus network. Which type of IPv6 addresses can be used for these networks in the IPv6 addressing design?

Answer options

• A. link-local addresses
• B. private addresses
• C. unique local addresses
• D. local addresses

Correct answer: C

Explanation

The correct answer is C, unique local addresses, as they are specifically designed for local communication within a site and are not routable on the global Internet. Option A, link-local addresses, are only valid on the local link and cannot be used for addressing across different subnets. Option B, private addresses, is a term more commonly associated with IPv4, and option D, local addresses, is not a standard term used in IPv6 addressing.
