Answer: C

Explanation:

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 evolution ability is poor.
