• Question 31:

  A node of an OceanStor 9000 goes offline due to a power module failure and gets online again two days later. If the administrator does not manually restore data, the system automatically updates the data changes made during the offline period to the node.

  A. True

  B. False

  Correct Answer: A

• Question 32:

  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.

  Correct Answer: ABCD

• Question 33:

  Which of the following statements about the erasure code N+M redundancy by Huawei OceanStor 9000 is false?

  A. Different data protection levels can be set different directories and files.

  B. Data written to an OceanStor 9000 is divided into chunks at a size of 4GB.

  C. The erasure code algorithm calculates M parity chunks for every N consecutive chunks.

  D. The utilization rate of storage space is about N/(N+M), and reliability is determined by M, where a larger value of M results in higher reliability.

  Correct Answer: C

• Question 34:

  The OceanStor 9000 employs general-purpose x86 hardware to set up the scale-out NAS architecture. Relying on IB, 10GE, and PCIe networking, nodes deliver high concurrency and outstanding performance. Compared with the other two networks, the PCIe network has better scalability and is easier to manage.

  A. True

  B. False

  Correct Answer: B

• Question 35:

  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.

  A. True

  B. False

  Correct Answer: A

• Question 36:

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

  A. Capacity quota

  C. Calculation quota

  D. Mandatory quota

  Correct Answer: AB

• Question 37:

  What are the reasons for rapid development of the enterprise cloud storage? (Choose all that apply.)

  A. Enterprises have strong demands or resource pooling, shorten product go-to-market time, and reduced cost.

  B. Storing service data to the cloud can reduce the possibility of misoperation and malicious theft compared to storing the data on the local PC.

  C. Enterprise cloud storage can help improve the performance and reliability of typical or new applications.

  D. For typical scenarios such as VSI, VDI, and big data, enterprise cloud storage conserves more storage space, provides larger bandwidth, and enhances compatibility between virtual machines (VMs).

  Correct Answer: ACD

• Question 38:

  C. Cables or optical modules

  D. I/O modules

  Correct Answer: D

• Question 39:

  Before restriping, Huawei OceanStor 9000 determines whether the used space of the node pool in the target tier reaches the read-only watermark. Restriping is implemented only when the used space is lower than read-only watermark.

  A. True

  B. False

  Correct Answer: A
