문제4

Which of the following descriptions about IPv6 transition technology is correct?

A. IPv4/IPv6 dual-stack technology has hardware requirements for the device, and two network cards are required to run IPv4/IPv6 respectively

B. Conversion technology is suitable for communication between pure IPv4 network and pure IPv6 network, which is convenient for network management and auditing
