Question 271

Which of the following statements about synchronous remote replication of the Huawei Active-Passive DR Solution is correct?

A.The link distance between the two data centers cannot be longer than 150 km, and the round-trip transfer latency cannot be longer than 2 ms.

B.The link distance between the hN0 data centers cannot be longer than 200 km, and the round-trip transfer latency cannot be longer than 2 ms.

C.The link distance between the two data centers cannot be longer than 100 km, and the round-trip transfer latency cannot be longer than 4 ms.

D.The link distance between the two data centers cannot be longer than 300 km, and the round-trip transfer latency cannot be longer than 8 ms.

Question 272

Parallel deduplication is highly reliable. The built-in failover capability enables uninterrupted backup operations. Even if one node in the grid is unavailable, the remaining nodes can continue to work and take over the backup. The failed node is automatically repaired in the background, and then joins the network to continue working.

A.False

B.True

Question 273

On Huawei OceanStor 9000, if access requests are not evenly allocated to nodes, a user can adjust zones. After that, the user must unmount shared directories from clients and remount directories based on allocated domain names.

A.FALSE

B.TRUE

Question 274

Which of the following statements are correct about the HyperMetro static priority arbitration mode? (Multiple choice)

A.The static priority mode has higher reliability than the arbitration server mode.

B.When the priority site array is actively powered off for maintenance, the non-priority site array immediately takes over all active-active services, and services will not be interrupted.

C.When the priority site array fails, the non-priority site will automatically take over the active-active service.

D.When an inter-array link failure occurs, or a non-priority site fails, the LUN on the priority site continues to provide services, and the LUN on the non-priority site stops providing services.

Question 275

For OceanStor V3 SmartMigration function: The capacity of the target LUN can be smaller than that of the source LUN, as long as the available capacity is sufficient.
