Exam 10: Huawei Certified Network Professional- Constructing Big Data Solution

Which of the following is not included in the FusionStorage network architecture?

In an N8500 clustered NAS system, the Veritas Volume Manager (VxVM) is located between the operating system and the data management system. The VxVM accesses disks using the interface provided by the operating system, makes the physical storage devices connected to hosts invisible, and provides a logical device layer for the data management system. The logical devices on this layer are called VxVM volumes.

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.

The three mainstream storage forms are as follows: 1)SAN storage that provides block resources; 2)NAS storage that provides file system resources;3) object-based storage (OBS). SAN storage and NAS storage are traditional storage forms. Which of the following statements about the characteristics of the three storage forms are correct? (Select three.)

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

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

After the Hadoop service is interconnected with the OceanStor 9000 through the HDFS API, what data redundancy and protection mechanism is adopted?

If a disk in an OceanStor 9000 stays offline for 15 minutes, the system obtains the data on the disk through calculations and then writes the data to other functional disks.

When the communication between MDC and OSD is interrupted or the OSD is faulty, the OSD exists the storage pool. Then the OSD out-of-service alarm is reported. Which of the following are the possible cause of this fault? (Choose all that apply.)

If homedir is enabled and a directory is specified, the OceanStor 9000 will automatically create a user directory for each user in the specified directory when local users or domain users access the OceanStor 9000 from clients for the first time. The users are authorized to read and write their own user directories. Other users, however, cannot access those user directories by default.

Which of the following statements about CIFS are correct? (Select two.)

Which of the following statements about the bucket is incorrect?

A NAS storage system is dedicated to storing and managing which data type?

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

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

Which functions are provided by InfoAllocator for OceanStor 9000 administrators? (Choose all that apply.)

Which of the following statements about InfoRevive is correct?

A C72 node is a 4 U large-capacity archive storage node. It can be fully populated with 72 SAS disks to adapt to the scenarios that have demanding requirements for both performance and capacity.

CIFS/NFS/FTP sharing implemented by Huawei OceanStor 9000 is intended for which object?

An OceanStor 9000 is equipped with six C72 nodes. How many nodes' NIC0 must be connected to the management network?
