Which of the following IPv6 transformation solutions for data center networks only needs to transform the egress gateway to support IPV4/IPv6 dual-stack services, which requires less transformation effort and less impact on existing network services?
Correct Answer: C
Analysis: Features: It is suitable for temporary solutions in the initial stage, and is not recommended. Advantages: Only need to transform the egress to dual-stack and deploy NAT64, which requires less transformation work, less impact on live network services, and can quickly provide IPv6 services. Disadvantages: NAT conversion will cause ALG problems, and the solution cannot smoothly evolve to the long-term goal of "network-wide single-stack", and the evolutionability is poor.
