Which of the following is not a possible impact of modifying the storage device time?

Modifying the device time will affect the life of the hard disk, controller, etc., and may trigger an alarm for hardware expiration or aging.

If the modified device time is greater than the password validity period configured by the user, the system may force the user to change the login password.

If the modified device time exceeds the set deadline for saving historical performance data, the system will no longer save historical performance data.

If the modified device time exceeds the certificate validity period, the certificate will expire

Question 5 of 33

During the tuning process, you can run the upadm showoption command to view the multipath configuration and confirm that the multipath function has been disabled.

During the tuning process, you must use the show performanceport command to view the backend port performance indicators to assist in problem location.

To address this problem, you can usually use the echo noop >/sys/block/sdc/queuelscheduler method to temporarily modify the scheduling algorithm of the block device to optimize the multipath ping-pong effect.

Question 9 of 33

10. Which of the following descriptions of the networking principles of Huawei flash storage device disk enclosures is wrong?

The P0 port of the disk enclosure is an upstream port and can only be connected to the P1 port of the upper disk enclosure.

The P1 port of the disk enclosure expansion module is connected to the P0 port of the next-level disk enclosure expansion module

Disk enclosure cascading networking usually adopts full positive connection

The interface modules of the two ports on the controller enclosure connected to the same disk enclosure should be symmetrical and have the same port number.

Question 10 of 33

11. Which of the following descriptions about the principle of the Flash Storage HyperReplication feature is wrong?

In synchronous remote replication mode, after the primary storage system receives a write I/O request from the host, it will send the write I/O request to the slave LU and the primary LUN at the same time. When both the primary LUN and the slave LUN are written successfully, it will return the write I/O success result to the host.

Asynchronous remote replication mode relies on snapshot technology. When the host initiates a write operation request, the storage system will return a successful write request to the host only if the write from the LUN is successful.

Remote replication can be divided into two modes: synchronous and asynchronous. The principles of writing data to the slave LUN are different in different modes.

In synchronous remote replication mode, the primary LUN of the production site and the secondary LUN of the disaster recovery site will establish a synchronous remote replication relationship and start the initial synchronization.

Question 11 of 33

12. A scientific research customer purchased several Huawei distributed storage systems for HPC business deployment. In order to ensure the performance requirements of the business, the engineer now needs to configure DPC file services on the storage system. Which of the following configuration descriptions of the engineer is correct? One item?

If an engineer wants to enable the feature that allows the creation of namespaces with the same name for different accounts, this can be achieved by executing the change space ops cnd-sameFsName args-set,1 command

Engineers can install DPC software in an existing container environment and need to configure the container node and install the network management component.

After the fusion storage pool is created, engineers need to enable the object service and big data service types of the nodes in the storage pool, while the file service type does not need to be checked.

When creating a disk pool, engineers do not need to select main memory and cache, but need to configure the grading level.

Question 12 of 33

13. A financial customer wants to configure the DME IQ service to perform daily management of flash storage. Before setting up DME IQ, it is necessary to open the server port of the DME IQ cloud to ensure that the storage device can send HTTP requests to the DME IQ cloud normally.
Which of the following ports does not belong to the ports that need to be opened?

8448/TCP

8900/TCP

7448/TCP

9448/TCP

Question 16 of 33

17. A financial customer purchased several Huawei distributed storages. Engineers now need to install the distributed storage software through LID configuration.
Which of the following descriptions of LID configuration is wrong?

When installing software using LID, engineers need to create a LID configuration file

Before engineers use the LID Designer tool to create LID configuration files, they need to complete the planning of system deployment parameters and IP addresses.

In LID configuration mode, engineers need to manually complete operations such as node addition and network configuration on the DeviceManager interface.

In LID configuration mode, engineers can use SmartKit to configure node iBMC IP addresses, configure node management, and other operations based on the exported configuration file.
