In an OceanStor 9000 storage system, hard quotas are set for user A to access the /dir directory. The recommended threshold is 3 GB, the soft threshold is 4 GB, the grace period is 10 days, and the hard threshold is 6 GB. If user A has written 3.1 GB data in the /dir directory, which of the following statements are correct? (Select two.)

A. The system reports an alarm indicating that the threshold is exceeded.

B. User A can continue to write data in the /dir directory.

C. User A can continue to write data in the /dir directory for another 10 days.

D. User A cannot continue to write data in the /dir directory.

Which of the following statements about the file system mirroring feature provided by an N8500 clustered NAS system are incorrect? (Select two)

A. The N8500 supports a maximum of two mirrors for a single file system.

B. Resources of different storage pools can be selected to implement file system mirroring.

C. File system mirroring allows users to select three mirroring layout types.

D. In the same service scenario, mirrored-stripe and striped-mirror provide the same data reliability and performance.

In the cluster communication architecture employed by an N8500 clustered NAS system, modules such as the resource agent, HAD, GAB, and Low Latency Transport (LLT) must collaborate to implement cluster communication.

Which of the following statements about the work mechanisms of these modules are correct? (Select three)

A. The agent monitors the resources of each system and provides the status information for the HAD of each machine.

B. If a cluster node is abnormal or faulty, the HAD takes correct actions, for example, performing a failover.

C. The GAB implements a point-to-point communication mechanism. The master node sends the other cluster nodes the information that needs to be synchronized.

D. LLT is a MAC-layer protocol unrelated to IP layer.

The mirrored-stripe file system of the N8500 clustered NAS storage systems is ideal for scenarios that require high data security and read/write performance. Which of the following is the major technical feature of the mirrored-stripe file system?

A. Data is striped and then mirrored, as in RAID 01.

B. Data is mirrored and then striped, as in RAID 10.

C. Data is stored in sequence on data disks that compose the file system.

D. Data is stored in an interlaced manner on multiple data disks that compose the file system.

An OceanStor 9000 must be equipped with a minimum of three nodes that can vary in types.

A. True

B. False

Huawei OceanStor 9000 can provide the SMB3 Multichannel function.

A. True

B. False

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

A. OBS

B. MDS

C. PVS

D. CA

Which are characteristics of the FTP service provided by Huawei OceanStor 9000? (Choose all that apply.)

A. The objects shared by the FTP service are directories, and such a shared directory is accessible to multiple clients.

B. Load balancing is implemented based on the states of services and nodes. Data access requests are evenly distributed in the cluster.

C. The sharing service is provided by a cluster. Nodes in the cluster can monitor the service of each other.

D. The FTP service is compatible with a wide range of operating systems, allowing file resource sharing in a heterogeneous network environment.

Scale-out is a horizontal expansion architecture that addresses the needs and challenges produced by rapid data growth and complex data changes.

Which are characteristics of the scale-out architecture? (Choose all that apply.)

A. Distributed processing

B. Online expansion

C. Data sharing

D. Clustering

How does HDFS Plugin store the Hadoop service data directly into the OceanStor 9000?

A. HDFS Plugin is deployed on Hadoop nodes and is used to convert the HDFS protocol-based access requests to CIFS protocol-based access requests.

B. HDFS Plugin is deployed on Hadoop client and is used to convert the HDFS protocol-based access requests to NFS protocol-based access requests.

C. HDFS Plugin is deployed on Hadoop nodes and the Hadoop client and is used to convert the HDFS protocol-based access requests to CIFS protocol-based access requests.

D. HDFS Plugin is deployed on Hadoop nodes and the Hadoop client and is used to convert the HDFS protocol-based access requests to NFS protocol-based access requests.
