This question addresses the behavior of remote replication during a primary/secondary switchover in

Huawei flash storage systems, such as OceanStor Dorado. The *HCIP-Storage V5.5 Training Material

(Module 4: Storage Design and Implementation)* explains: “During a primary/secondary switchover

in remote replication, the secondary site becomes the primary site and starts accepting write I/Os.

The original primary site, if available, becomes the secondary site. Data changes are tracked

incrementally, but full synchronization does not occur automatically after the switchover unless

explicitly configured or triggered by a fault recovery process.” The question’s statement that “all data

will be synchronized” implies an automatic full synchronization, which is not the default behavior.

Instead, only incremental changes are synchronized when replication resumes, making the statement

false.
