Which of the following statements is false about the working principles of HyperReplication?

1. A. In synchronous remote replication mode, after receiving a write I/O request from a host, the primary storage system sends the write I/O request to both the primary and secondary LUNs. After data is successfully written to both the primary and secondary LUNs, the write I/O is returned to the host.
2. B. Asynchronous remote replication relies on the snapshot technology. When a host initiates a write request, the storage system returns a write success message to the host only after data is successfully written to the secondary LUN. — đáp án hiện tại
3. C. In synchronous remote replication mode, a synchronous remote replication relationship is set up between a primary LUN at the production site and a secondary LUN at the DR site, and initial synchronization is started.
4. D. Remote replication can be implemented in synchronous or asynchronous mode. The principle of writing data to the secondary LUN varies according to the mode.
