質問 4

A new engineer is learning about Huawei's distributed storage products and does not understand DPC file services. Please help him determine which of the following descriptions of DPC are wrong? (Multiple choice)

A. If the engineer wants to enable CPU performance mode, he can use the cpupowerfrequency-set - g performance command to buy cash

B. DPC itself and NUMA are mutually exclusive, so in actual scenarios, it is impossible to provide NUMA affinity optimization features.

C. If engineers want to deploy DPC resource reservation, the remaining memory of the computing node must not be less than 8G, of which the operating system reserves no less than 4G.

D. When the business running on the DPC requires higher performance, engineers can set the CPU to performance mode.

正解: B,C

質問 7

Assume a government office purchases the Huawei OceanProtect Appliance. Which statement about the device initialization is false?

A. If the engineer uses the Network Time Protocol (NTP) automatic synchronization mode to configure the device time in a firewall-enabled environment, port 123 must be enabled.

B. The engineer needs to configure service logical ports before configuring networks. If there are two OceanProtect backup storage nodes, at least two IP addresses must be reserved from the backup service network segment.

C. During network configuration, if the archive network and backup network are separate, the engineer needs to disable the function of reusing the backup network configuration.

D. The engineer needs to configure the Secure File Transfer Protocol (SFTP) service. If management data exists before the SFTP service is enabled, the management data file becomes invalid after the SFTP service is enabled.

質問 10

FILL BLANK
For the storage performance evaluation system, there are two performance testing benchmarks for SAN storage performance certification. Of the two benchmarks, _______ is used to measure the SAN array performance in email and OLTP applications in scenarios where random small I/Os are quickly responded.

正解:

SPC-1
Explanation:
SPC-1 is a benchmark designed to measure SAN storage performance under workloads typical of email and OLTP applications, focusing on rapid response to random small I/O operations.

質問 11

A scientific research customer has purchased several Huawei scale-out storage devices for high- performance computing (HPC) service deployment. To ensure service performance, an engineer wants to install the distributed parallel client (DPC). Which of the following statements is true about the configuration?

A. When creating a disk pool, the engineer does not need to select the main storage and cache disks, but needs to configure a tier grade.

B. To enable the function of creating namespaces with the same name for different accounts, the engineer can run the "change space ops cmd=sameFsName args=set,1" command.

C. The engineer can install the DPC software in an existing container environment. To install the DPC, the engineer needs to configure the container node and install network management components.

D. After a converged storage pool is created, the engineer needs to enable the object and HDFS services for nodes in the storage pool. The file service does not need to be enabled.

正解: B

質問 12

An enterprise provides a variety of services to users. In order to meet different business needs and allocate resources reasonably, the administrator needs to configure the SmartQuota feature.
Which of the following descriptions about creating quotas are correct? (Multiple choice)

A. When creating a quota for a specified user or user group, you need to create the user or user group first.

B. Before creating a quota, you need to complete the creation of a namespace or Dtree.

C. When creating a user or user group quota for a namespace (i.e. Dtree is left empty), the namespace for which the quota needs to be created is empty

D. When creating a quota for a specified Dtree, the selected Dtree must be empty.

正解: A,B

質問 13

A financial customer has purchased several Huawei OceanStor Dorado series storage devices for mission-critical service deployment. SmartMigration is configured to migrate services from a source LUN to a target LUN without interrupting host services. Which of the following statements about this feature is false?

A. When configuring this feature, you cannot use a LUN that has been mapped to an application server as the target LUN of a SmartMigration task.

B. The implementation of a SmartMigration task between heterogeneous storage systems depends on the LUN takeover function provided by SmartVirtualization.

C. The higher the migration rate, the better the host service performance is. Therefore, the highest migration rate can be used when the host service load is heavy.

D. When configuring this feature, you must plan the capacities of the source and target LUNs. The capacity of the target LUN must be greater than or equal to that of the source LUN.
