質問 4：
In thescenario of database protection, when the slave uses the virtual snapshot to verify LUN data consistency on the production end and the DR end and the disaster recovery end LUN database can not be started normally. Which of the following are the possible reasons for this? (multiple choice)
A. When creating a snapshoton the disaster recovery end LUN The production end is copying data to the disaster recovery end
B. After a snapshot of the LUN of the redundancy site is created, the snapshot is not activated at the same time
C. Disaster recovery data stored in the Cache, not yet written to the hard disk
D. The production end and disaster recovery end adopt the disaster recovery solution of incremental LUN copy. The incremental data is abnormally interrupted during the synchronization process and has not been recovered
正解：A,B,D

質問 6：
A TV station plans to adopt Huawei OceanStor 9000 as a back-end storage system, with 10 OceanStor 9000 C nodes, planned to be deployed in 4 standard cabinets, with all backends connected to a pair of stacked back-end CE6850 switches. There is no single customer in the existing networking standalone management network. Which of the network IP address planning described below is incorrect?
A. You can plan back-end storage network for 9000 internal communications, without planning gateway address, and front-end network with the same network segment IP address.
B. The external NTP server address and the Oceanstro 9000 front-end network need to communicate to ensure that the oacenstor 9000 system and client applications maintain time synchronization.
C. Oceanstor 9000 front-end network and management network can be considered together, planning for the same network segment.
D. Back-end CE6850 switches need to use four stacked cablesfor stacking connection to ensure bandwidth requirements
正解：A

質問 7：
In the N8500 (V200R001) clustered NAS system, when the created file system is used for applications accessing large files sequentially, which of the following is correct?
A. For reliability, the recommendednumber of file systems is less than 40
B. From a performance perspective, it is recommended that the total number of files in a single file system be less than 80 million
C. In order to allow clients to access a single file system, N8000 can provide higher bandwidth and capacity, it is recommended to create a striped file system
D. Large file access business is a large IO sequential read and write, choose a smaller size of the strip and block size to provide higher bandwidth
正解：B

C. Make an incremental synchronization.
D. Add the remote device to the originalproduction array
E. Stop the current production business
正解：B,D
