CCNA: Cisco Certified Network Associate — Question 629

What is a similarity between global and unique local IPv6 addresses?

Answer options

• A. They use the same process for subnetting.
• B. They are part of the multicast IPv6 group type.
• C. They are routable on the global internet.
• D. They are allocated by the same organization.

Correct answer: A

Explanation

The correct answer is A because both global and unique local IPv6 addresses use similar subnetting techniques to organize the address space. Options B and C are incorrect as unique local addresses are not routable on the global internet and they are not part of the multicast group. Option D is also incorrect since global addresses are assigned by the IANA and regional registries, whereas unique local addresses are not allocated by any organization.
