• Question 11:

  Which statement about SmartMigration functions is false during a SmartMigration-based migration?

  A. If multiple LUNs are used by a service, the LUNs must undergo a consistency splitting after the migration.

  B. If multiple LUNs are used by a service, consistency splitting cannot be performed before stopping services.

  C. For higher migration speed and storage performance, a migration task can be deleted as soon as it is completed.

  D. It is recommended to perform consistency splitting in off-peak hours.

  Correct Answer: B

• Question 12:

  A customer's database application is running on an OceanStor V3 storage system. The database uses six LUNs. The customer wants to migrate data from the OceanStor V3 storage system to an OceanStor 18000 series storage system based on the functions provided at the storage side. Which statements are true? (Multiple Choice)

  A. If you use the HyperReplication function to migrate data on multiple LUNs used by the database, you must add multiple remote replication tasks to one consistency group.

  B. The HyperReplication function can implement online data migration.

  C. After data is migrated using HyperCopy or HyperReplication, services can be started without the need to make any configuration on the host.

  D. If data is migrated using HyperCopy, the migration speed can be dynamically changed during the copy process.

  Correct Answer: ACD

• Question 13:

Taking over the source storage; d. Migrating data; e. Recovering services and applications. Which sequence correctly describes an online migration procedure?

  A. acbde

• Question 14:

  An application's peak write throughput is 10 MB/s, average write throughput is 280 KB/s, average write I/O size is 4 KB, and the network bandwidth utilization rate is 70%. If OceanStor V3 storage systems are used to implement data disaster recovery based on asynchronous replication, Synchronization Method is set to Timed wait when synchronization begins, and the value of Interval is 4 hours, the expected duration to synchronize data is no more than 1 hour. So the minimum network throughput should be (_).

  A. 1600 KB/s

  B. 400 KB/s,

  C. 15 MB/s

  D. 10 MB/s

  Correct Answer: A

• Question 15:

  Huawei HyperMetro active-active disaster recovery supports heterogeneous storage. Therefore, an OceanStor V3 storage system and a Huawei certified third-party storage system can work in active-active mode based on HyperMetro.

  A. TRUE

  B. FALSE

  Correct Answer: A

• Question 16:

  As shown in the figure, the main features of this backup network mode are: (Multiple Choice)

  

  A. Backup tasks will consume a lot of LAN resources.

  B. Backup tasks will consume few LAN resources.

  C. Backup tasks will consume a lot of CPU resources of the production system.

  D. Backup tasks will consume few CPU resources of the production system.

  Correct Answer: BD

• Question 17:

Which of the following disaster recovery technologies is working as the above statement?

  A. LogReplecation

  B. DataGuard

  C. GoldenGate

  D. VVR

  Correct Answer: B

• Question 18:

  In a synchronous replication scenario, an application's peak write throughput is 16 MB/s, average write throughput is 500 KB/s, average write 1/0 size is 8 KB, private information overhead is about 11%, and the FC network bandwidth utilization rate is 70%. The throughput of the disaster recovery network must be at least ( ).

  A. 206 Mbit/s

  B. 23 MB/s

  C. 16 MB/s

  D. 800 KB/s

  Correct Answer: C

• Question 19:
