Question
The best practice of disaster recovery in two locations and three centers (storage disaster recovery service SDRS + cloud backup CBR) is a disaster recovery solution launched to ensure business continuity when a disaster occurs. The SDRS+CBR disaster recovery solution includes synchronous replication disaster recovery across availability zones in the same region and cross-region backup disaster recovery. The principle is shown in the figure. Which of the following descriptions of this solution are correct? (Multiple choice)
