H13-622 Online Practice Questions and Answers

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

Which of the following statements about the OceanStor Toolkit installation of the OceanStor 9000 is incorrect?

A. The OceanStor Toolkit can be installed on any storage node.

B. The PC used for installation is connected to a storage node through port eth0.

C. The IP address of the network port used to upload the OceanStor Toolkit must be configured on the same network segment as the management network.

D. After the OceanStor Toolkit is successfully installed, enter https://xx.xx.xx.xx:8088/tools in the Internet Explorer address box to go to the login page.

A. NIC

B. Hashadow

C. Disk

D. IP

If the InfoLink license is not activated in an OceanStor 9000 storage system, the system cannot balance loads coming from clients.

A. True

B. False

The %util value of back-end disks frequently exceeds 90% after the iostat command is run. This indicates that the bandwidth utilization is high and performance bottlenecks exist.

A. True

B. False

Which of the following device indicator states will not appear after an OceanStor storage system powers up and operates properly?

A. The system Alarm indicators are off.

B. The disk Running indicators are steady green.

C. The disk Alarm/Location indicators are steady red.

D. The system Running indicators on the GE switches are blinking green.

Which of the following statements about the Global Cache technology employed by the WushanFS are correct? (Select three.)

A. Global Cache enables the memory space on all storage servers to form a unified memory resources pool logically.

B. Data cached on a node cannot be hit by the read/write service of another node.

C. Global Cache helps improve the sharing of memory resources among nodes.

D. The WushanFS uses the distributed lock mechanism to implement global management of cached data. The same service data is cached only on one node. Another node that needs to access the service data can apply for a lock to obtain the cached data.

If an application server cannot access the storage resources of an N8500 storage system, which of the following operations can be performed for troubleshooting? (Select three.)

A. Log in to the ISM to check alarms.

B. Check the indicators on the storage system.

C. Reinstall the ISM software.

D. Restart the sharing service.

C. A node pool that consists of P nodes must contain a minimum of three nodes.

Which of the following statements about data protection functions provided by Huawei OceanStor 9000 is false?

A. Huawei OceanStor 9000 uses the erasure code technique to provide N+M redundant storage of data.

B. Huawei OceanStor 9000 uses the mirroring technique to provide redundant storage of metadata.

C. If physical domains are used, the failure of a disk or node in one domain will deteriorate the data reliability of other domains or even cause data loss.

D. If the protection level is N+1, a cluster requires a minimum of three nodes.

Which of the following statements about versioning for buckets are correct? (Choose all that apply.)

A. You can check whether the versioning is enabled by viewing its state.

B. You can use versioning to save, query, and restore objects of different versions

C. The versioning state can be configured and queried.

D. Versioning cannot be used to retain and archive data.
