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 storage cluster has five P36 nodes and adopts 10GE networks at the front back ends. The front-end
service network provides two 10GE ports.

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?

When planning RAID for an N8500 clustered NAS storage system, you are advised to configure RAID 10 for database services and random read/write services.

You can check VCS cluster logs by viewing the Engine_A.log file in the /var/VRTSvcs/log directory on an N8500 storage system.

Which authentication modes are supported by the NFS service of Huawei OceanStor 9000? (Choose all that apply.)

Object storage implemented by the OceanStor 9000 Wushan file system is aimed at data but not at metadata.

For N800 V200R001, you can log in to the storage system using the support account and run fsck -t vxfs -o full -y /dev/vx/dsk/sfsdg/fs001 to implement full verification for the fs00l file system.

Which of the following are characteristics of big data? (Select three)

Which of the following statements about the performance optimization check items of the N8500 clustered NAS storage systems are correct? (Select three)

Which of the following statements about the VxVM implementation mechanism employed by an N8500 are correct? (Select two)

S5752 or S5352 switches AC power modules only.

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

In the InfoEqualizer feature provided by Huawei OceanStor 9000, a zone is a collection of nodes. Different zones are isolated and provide different services. Nodes in a zone have the same dynamic and static domain names as well as characteristics of automatic load balancing.

An application requires high write performance and moderate reliability. To ensure that the N8500 clustered NAS storage system delivers the optimal write performance, set the LUN write policy to write back with mirroring.

Huawei OceanStor 9000 provides a single file system offering a unified file system namespace.

Which of the following statements about the unified file system namespace provided by Huawei OceanStor 9000 is false?

Which of the following types of clients are supported by NFS sharing of the OceanStor 9000? (Select

three)

Which of the following technologies is not suitable for the challenges brought by big data?

An N8500 provides synchronous volume mirroring, which is similar to implementation of RAID 1 for the file system.

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

An OceanStor 9000 storage system is deployed using the OceanStor Toolkit.

Which of the following statements about the settings of the OceanStor Toolkit configuration file are correct? (Select two)

Which of the following are the mandatory hardware components of an N8500 clustered NASsystem? (Select two)

Which of the following statement does not belong to the basic object operations?

In an OceanStor 9000 storage system, the calculate quota is set to 50 GB for user A to access the /dir directory. When the amount of data that user A writes exceeds 50 GB in the /dir directory, the system allows user A to continue to write data in the /dir directory.

There are four types of ports on the N8500 clustered NAS engine nodes: heartbeat port, management port, service port, and storage port.

Which of the following statements about the port types in the figure are correct? (Select two.)

A big data processing system involves five layers: data collection, data storage, data processing, data analysis, and data application and presentation.

Which of the following statements about the five layers are correct? (Select two)

Which quota types are supported by the InfoAllocator feature of Huawei OceanStor 9000? (Choose all that apply.)

The license must be purchased for which of the following software features of the OceanStor 9000? (Select three.)

Which of the following statements about the InfoLink feature of the OceanStor 9000 are correct? (Select two.)

A customer has purchased a 4-node N8500 clustered NAS storage system. The enterprise-edition engine nodes have two CPUs, 10GE network ports, and 48 GB cache. The performance of an engine node reaches 700 MB/s. The back-end storage uses the S5600T, which is configured with 80 SAS disks divided into eight 9-disk RAID 5 groups. Each RAID group has one hot spare disk. The performance of each SAS disk in the 9-disk RAID 5 groups is 30 MB/s.
