The correct answer is B. If you use an asynchronous remote solution, you need to design the startup synchronization time C. According to the business pressure of each LUN stored on the master side, the controllers of each D. In scenarios where RPO is not required to be zero, it is recommended to use an asynchronous. See the full explanation below for the reasoning.
