Question 91

It can prevent failures in time, analyze and accurately locate failures, and automatically analyze the root causes of errors. Which of the following are hardware fault isolation? (Multiple choice)

A.Realize the fault handling of hardware such as CPU and memory

B.Support dynamic loading mechanism of diagnosis / response components

C.Support batch deployment and one-click hot patch installation

D.Realize CPU core MEM isolation technology

Question 92

What is the correct statement about data routing and cluster management in the Huawei Fusionstorage architecture? (Multiple choice)

A.When the distributed storage system is created, N Partitions are generated in the space of 2 to the 32th power, and the backup OSD starting write data corresponding to the Partition is generated according to the distribution of the disk.

B.Query the main MDC when VBS starts and register with the main MDC.

C.When the system starts, MDC and ZK interact to determine MC, and the main MDC and other MDCs monitor each other's heartbeats. The master MDC decides who will take over after a certain MDC fails. Other MDC found that the main MDC was faulty and interacted with zk as the main MDC.

D.When the OSD starts, it queries the MDC from the MDC, reports the status to the home MDC, and the home MDC sends the status change to the VBS. When the home MDC fails, the master MDC designates one MDC to take over, and at most two pools belong to one MDC.

E.Distributed storage system writes data. According to the LBA from the application layer and the block size, the VBS generates multiple Keys in units of 1MB, hashes the Keys into Partition IDs, and then follows up the Partition to find the main OSD, and the main OSD notifies the partition corresponding to the OSD to start writing data.

Question 93

Which of the following statements about the docking feature of Huawei's hyper-converged management eService and the Plugin plug-in is correct?

A.HUAWEI hyper-converged integrated management and eService only supports sending alarms to the GTAC center (eService cloud), remote log collection, and does not support remote health checks, etc.

B.vCenter Plugin provides monitoring and management of the hardware and storage device resources of the Huawei HCI system. The system reports alarms but does not support the creation of management volume devices and virtual machine snapshots.

C.Customers can monitor and manage Huawei's hyper-converged system through the vCenter server to achieve unified management of the system on the vCenter interface. Only one set of HCI system access is supported.

D.Huawei Service Support Center supports drop-down selection (4) and manual entry (@Huawei.com mailbox). The mailbox server provided by the customer can communicate with Huawei's mailbox.

Question 94

TaiShan server adopts NUMA architecture. You can view the running status of NUMA through commands. If you need to view the number allocated by the local node and the number of processes allocated by other nodes, what data items should you pay attention to at this time?

A.numa miss

B.local node

C.other node

D.numa hit

Question 95

Huawei has achieved high-performance network acceleration through its self-developed network control chip. Which of the following are correct about the understanding of this network control chip? (Multiple choice)

A.Huawei IN series adopts standard card form, which is convenient for the deployment and operation and maintenance of various servers.

B.Through self-developed programmable network engine, Huawei Unique Networking smart network card can accelerate business in cloud network, cloud storage and other scenarios, while optimizing the utilization of infrastructure

C.Huawei IN series smart network card can support 2*100G/4*25G network card interface, and support PCIe Gen3 X16 system interface.
