HCPP-Storage Certification H19-338 Sample Questions

1. Dorado V6 LUNs have controller ownership.

True

False

2. To configure HyperMetro for LUNs that are carrying host services, you must first stop the host services.

True

False

3. HyperCDP objects can be used to restore data but cannot be directly mapped to hosts for read and write operations.

True

False

4. The full-stripe write technology supported by Dorado can effectively improve SSDs’ service life.

True

False

5. Controllers must be restarted during software NDU upgrade of Dorado V6.

True

False

6. When performing a controller fault test on the Dorado V6 mission-critical product models, ensure that each controller has a link to the host.

True

False

7. Which is the technology used for end-to-end protection of data integrity in the industry?

CRC

T10 PI

SHA

8. Which method can be used to upgrade a Dorado active-active (HyperMetro) solution to a 3DC solution?

Synchronous replication

Active-active

Asynchronous replication

Volume mirroring

9. Which of the following statements is incorrect about the Active-active architecture of Dorado V6?

LUNs are not owned by any controller.

The logical paths of the host are Active-Active.

Load is balanced among controllers.

ALUA must be configured when the operating system_x27;s native multipathing software is used.

10. What is the purpose of using sequential I/Os to overwrite all LUNs before testing Dorado performance?

To ensure correct deduplication and compression ratios

To ensure that all space of thin LUNs is allocated so read performance is close to that in actual scenarios

To provide better performance

11. Which of the following statements about the relationship between HyperMetro and multipathing software is correct?

HyperMetro can be used only when Huawei UltraPath is used

HyperMetro is irrelevant to multipathing software

HyperMetro supports native multipathing software of compatible operating systems, such as VMware NMP, MPIO, and Device Mapper

12. Which is NOT a typical application of HyperMetro for SAN?

Oracle RAC application

VMware vSphere application

SAP HANA application (in application mode)

SQL Server application

13. In static-priority arbitration mode, if the active-active relationships are functional, but all replication links between storage arrays are down, what will happen?

Services stop at the preferred site while they continue at the non-preferred site

Services continues at the preferred site while they stop at the non-preferred site

Services stop at both the preferred and non-preferred sites

Services continues at both the preferred and non-preferred sites

14. Which statement about the recommended deployment of the quorum device is true?

Deploy the quorum device at the preferred site.

Deploy the quorum device at the non-preferred site.

Deploy the quorum device at the third-place site.

Do not deploy the quorum device.

15. Which is the scale-out networking protocol that OceanStor Dorado V6 supports?

RoCE

PCIe

16. In database application scenarios, which is the recommended latency of the active-active (HyperMetro) replication network?

0.5

17. Which statement about the ROW technology for OceanStor V5 is true?

Block snapshots use the ROW technology

ROW-based snapshots do not have extra data copies, and therefore the performance is better.

One of the advantages of ROW is that it does not easily generate data fragments

18. Which technology does FusionStorage HyperSnap run on?

COW

ROW

19. The storage system monitors the responses to I/Os delivered to disks. If the responses exceed the upper limit, the RAID group experiences a read degrade to quickly respond to the hosts. This technology is called:

Online diagnosis

Slow disk detection

Rapid response to slow I/Os

20. Which statement about the replication network between storage arrays in an active-active (HyperMetro) network is NOT true?

The active-active (HyperMetro) replication network supports the FC network

The active-active (HyperMetro) replication network supports the IP network

The active-active (HyperMetro) replication network bandwidth must be larger than the average service bandwidth

Each controller of active-active (HyperMetro) arrays has at least two redundant links
