Considering the IPv6 address independence requirements, which process do you avoid when you use NPTv6 for translation?
A. rewriting of higher layer information
B. checksum verification
C. ipv6 duplication and conservation
D. IPSEC AH header modification

Correct Answer: A

Explanation:
The IPv6-to-IPv6 Network Prefix Translation (NPTv6) serves as a useful mechanism for implementing address independence in an IPv6 environment. A major benefit associated with NPTv6 is the fact that it avoids the requirement for an NPTv6 Translator to rewrite the transport layer headers which reduces the load on network devices
