A customer deploys a set of OceanStor V3 storage in two cities and adopts asynchronous remote replication networking between the two storage arrays. Which of thefollowing statement is correct? (Multiple choice.)

A.

The automatically created Asynchronous Remote Copy snapshot can either be a private quick pick or a public one.

B.

In a DR scenario, it is recommended to create a virtual snapshot of thesecondary LUN and map it to the host for access.

C.

In remote replication link networking, parallel networking is better than crossover networking.

D.

The number of LUNs in the consistency group should be as small as possible, and only the LUNs that have write dependencies on the same application are placed in a consistency group.

In preparation for disaster recovery design, which of the following is correct?

A.

Use the same type of disk as the master

B.

Raid should beset the same as the master

C.

The capacity of Lun and primary LUN is the same

D.

Use the same number of disks as the master

In a Huawei disaster preparedness plan using production site deployment with an oracle RAC cluster, to ensure that the disaster recovery database provides normal service should the production site fail, which of the following statements is correct?

A.

Disaster recovery end must be deployed, oracle rac cluster can not deploy oracle single node.

B.

Oracle RAC grid production side of the file must be copied to the disaster recovery side.

C.

Unable to copy the production sideof the FRA file will be able to guarantee the normal provision of services at the northern end.

D.

Production end of the oracle data files and log files can not be placed in the same consistency group.

In amanual recovery process, which of the following operations is not required? (Multiple choice.)

A.

Stop the current production business, delete the host mapping.

B.

Adding the remote device to the original production side array.

C.

With thedisaster recovery array as the master LUN and the original production array as the slave LUN, create the remote replication relationship between the DR and the production end and wait for the initial synchronization to be completed.

D.

Make an incrementalsynchronization.

E.

Delete the original production array consistency group.

When the database is protected and the virtual snapshots are used from the end to verify LUN data consistency on the production end and thedisaster recovery end. However, the disaster recovery end of the LUNd database can not be started normally. What is the possible reason? (Multiple choice.)

A.

After a snapshot of the LUN of the redundancy site is created, the snapshot is not activated atthe same time.

B.

Disaster recovery storage side of the database resides in the cache has not been written to the hard disk.

C.

When creating a snapshot on the disaster recovery end LUN, the production end is copying data to the disaster recovery end.

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 repaired.

Which of the following describes the correct process of disaster recovery and Huawei disaster recovery solution?

True or False, with a client using the SMB 1.0 / 2.0 / 2.1 / 3.0 protocol to perform file replication inside a Huawei OceanStor 9000, it does not need to pass through the client, but can be done directly to the system.

A.

True

B.

False

Single VIS device failure

B.

Single oracle failure

C.

A single data center full failure

D.

Third-party arbitration array failure
