Question 2

In a large and medium-sized database application, files such as data, logs, and modification records are stored in the associated LUN1, LDN2, and LDN3, respectively, and remote replication tasks 1, 2, and 3 are created respectively, and the engineer replicates these three remotely. The task is added to the consistency group.
Which of the following statements is true in this situation? (Multiple Choice)

A. If the remote replication task 2 fails during the data synchronization process, the consistency group will continue to complete the remote replication tasks 1 and 3. After the fault is cleared and recovered, the data synchronization of the remote replication task 2 will continue. B. The remote replication task 2 is accidentally created during the hard data step, and the consistency group will immediately stop the remote replication task 1 to 3 C. When a disaster occurs, use the slave storage system to restore data, and the data in the database is still valid D. These three sets of remote replication can only be transparently added to the consistency group on the primary storage system, and all remote replication slaves must be located on the same remote storage system

Question 9

Which of the following is wrong in the description of the file system snapshot feature of Huawei OceanStor hybrid flash storage?

A. When creating a snapshot of the file system, only the root node of the file system needs to be copied and saved, and a snapshot of the file system is formed. B. The file system snapshot data cannot be deleted directly. This part of the space can be released only after the snapshot is deleted. C. After the file system creates a snapshot, as the file system is continuously updated, the original data blocks will gradually become the space occupied by the snapshot, but the newly written data will not be counted in the space occupied by the snapshot. D. Deleting a snapshot adopts the mechanism of reclaiming space, so the snapshot data space is released immediately after the snapshot is removed.
