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
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 thatit avoids the requirement for an NPTv6 Translator to rewrite the transport layer headers whichreduces the load on network devices. http://www.cisco.com/c/en/us/td/docs/ios-xml/ios/ipaddr_nat/configuration/xe-16/nat-xe-16-book/iadnat-asr1k-nptv6.html
