Accepted Answer

The answer of Which of the following statements about switches...

Question 6

The InfoReplicator feature of Huawei OceanStor 9000 provides full synchronization and incremental synchronization. Incremental synchronization can be triggered manually or automatically.

Accepted Answer

The answer of The InfoReplicator feature of Huawei OceanStor 9000...

Question 7

Which of the following statements about the CIFS sharing configuration of Huawei OceanStor 9000 is false?

Accepted Answer

The statement is false because if "Enable notify" is selected, changes made by a client to a directory can be detected by other clients accessing the directory or its parent directory.

Question 8

A storage cluster has five C72 nodes and adopts 10GE networks at the front and back ends. When distributed file system service and object storage service are both deployed on nodes, how many IP addresses should be planned for the front-end service network?

Accepted Answer

The answer of A storage cluster has five C72 nodes...

Question 9

Huawei OceanStor 9000 uses the DFS to consolidate disk resources of all nodes, providing a unified namespace.

Accepted Answer

Huawei OceanStor 9000 uses a distributed file system (DFS) to pool disk resources from all nodes, creating a unified namespace for efficient data management and access.

Question 10

Which of the following ports is used for firewall software upgrade and advanced debugging in SX6018?

Accepted Answer

The answer of Which of the following ports is used...

Question 11

Huawei OceanStor 9000 employs decentralization. Therefore, the Wushan distributed file does not have performance bottlenecks. As the number of nodes increases, the storage capacity at the computing capability increase linearly, which in turn provides linearly increasing bandwidth and concurrency capabilities for users.

Accepted Answer

Huawei OceanStor 9000's decentralized architecture allows for linear scalability in storage capacity and computing capability, which helps avoid performance bottlenecks and provides increased bandwidth and concurrency as more nodes are added.

Question 12

Which of the following is not a software module at the adaption layer of the OceanStor 9000 DFS?

Accepted Answer

The answer of Which of the following is not a...

Question 13

In Huawei OceanStor 9000, which authentication mode is not supported by NFS sharing?

Accepted Answer

AD authentication is not supported by NFS sharing in Huawei OceanStor 9000.

Question 14

Which of the following statements about quota and statistics is incorrect?

Accepted Answer

The available bucket resources typically include the total capacity, the number of buckets, and the number of objects, but not the "bucket size" as a separate resource.

Question 15

Which feature of Huawei OceanStor 9000 can provide file system snapshots?

Accepted Answer

InfoStamper is the feature in Huawei OceanStor 9000 that provides file system snapshots, allowing users to create point-in-time copies of data for backup and recovery purposes.

Question 16

OceanStor 9000 object storage service (compatible with Amazon S3 Amazon APIs and OpenStack Swift APIs) provides RESTful APIs externally. Clients can store data to the storage nodes through the RESTful APIs.

Accepted Answer

OceanStor 9000 object storage service is designed to be compatible with Amazon S3 and OpenStack Swift APIs, which are RESTful APIs, allowing clients to store data to the storage nodes through these interfaces.

Question 17

Which sub-functions are included in the InfoProtector function provided by Huawei OceanStor 9000? (Choose all that apply.)

Accepted Answer

The answer of Which sub-functions are included in the InfoProtector...

Question 18

Which of the following is not a typical application scenario of cloud storage?

Accepted Answer

The answer of Which of the following is not a...

Question 19

Which type of log is not supported by FusionStorage?

Accepted Answer

FusionStorage does not support monitoring logs, as it primarily focuses on security, system, and operation logs for managing and maintaining storage systems.

Question 20

In Huawei OceanStor 9000, a node pool is a collection of nodes that have the same characteristics such as physical type and access performance, and dynamic storage tiering a user to group physical nodes in the same file system into different node pools.

Accepted Answer

In Huawei OceanStor 9000, node pools are used to group nodes with similar characteristics, and dynamic storage tiering allows users to organize these nodes into different pools within the same file system.
