Question 52

When planning an OceanStore Unified Storage Arraysynchronization remote replication, which of the following description is correct. (Multiple choice.)

Options:

In the scenario where the actual RPO indicator requires zero, you can choose to synchronize remote replication.

Synchronous remote replication canbe used to map the main and secondary storage of the two sets of LUN mapping to the host to create a scenario volume.

Synchronous remote replication on the remote disaster recovery can be well done.

Because synchronous remote replication does not usesnapshots, after synchronous remote replication is interrupted abnormally, the data on the primary LUN needs to be resumed in reply.Start synchronization to the slave site.

Client1 needs to read file X from a Huawei OceanStor 900 and the node that responds to the read request is node A.

Based on this, which of the following are correct?

Options:

If the system has monitored the file X hasbeen cached on Node B, the client client1 can read the file directly from Node B.

If the system monitors that node B has cached file X, then node A can read the file from node

After HUAWEI OceanStor 9000 processes the request for reading the file X from client1, the system reserves the message on both node A and node B.

If the system monitors that node A has cached file X, then node A only caches the data of file X and does not cache its verification data

Question 54

What is correct about the reconstruction of the Huawei OceanStor V3 storage system? (Multiple choice.)
