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. According to the preceding information, what is the overall performance of the N8500 without considering other factors?

A. 700 MB/s

B. 2800 MB/s

C. 1920 MB/s

D. 2400 MB/s

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.

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

A. Capacity quota

B. File quantity quota

C. Calculation quota

D. Mandatory quota

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).

Which module or device cannot be replaced by using the OceanStor 9000 FRU replacement tool?

A. Power modules

B. Disks

C. Cables or optical modules

D. I/O modules
