H13-623 by Huawei Actual Free Exam Q&As

Question 1

Which of the following statements about synchronous remote replication implemented by OceanStor V3 storage systems is false?

A. The primary storage system writes data to the primary LUN and sends the data to the secondary LUN. B. After data is successfully written to both the primary and secondary LUNs, the primary storage system returns a write success response to the host. C. The impact of synchronous remote replication on the write performance of a host is not related to the distance between the primary site and the secondary site. D. Synchronous remote replication implemented by OceanStor V3 storage systems allows data to be simultaneously replicated from one primary LUN to two secondary LUNs.

Question 7

Is the Active-Active DR Solution feasible for the scenario where the existing third-party storage system and a newly purchased OceanStor 5300 V3 are deployed in the two data centers separately?

A. No. An Active-Active DR Solution requires at least one set of OceanStor 5600 V3 or higher-level storage. B. Yes. All conditions required for the solution are met. C. No. An Active-Active DR Solution requires at least one set of OceanStor 5800 V3 or higher-level storage. D. No. An Active-Active DR Solution requires that two OceanStor 2600 V3 or higher-level storage devices be separately deployed in the two data centers.

Question 8

Huawei's end-to-end active-active data center solution is divided into six logical layers, namely, storage, computing, application, network, transmission, and security layers. Which are key points in designing these layers? (Multiple Choice)

A. The computing layer uses virtualization platforms such as FusionSphere and VMware to provide cross-data-center clustering, thereby enabling multiple mission-critical applications to run in active-active mode. B. The security layer uses Huawei USG series to provide security protection functions such as FW and IDS for data centers. C. The transmission layer employs optimization approaches such as dispersion compensation to ensure the minimum latency on the transmission layer. D. The storage layer uses the FastWrite function to reduce two round trips to one for each standard write I/O, thereby improving the write performance.

Question 11

In the HyperMetro active-active data center solution, if a member LUN has bad blocks, which of the following statements is false?

A. If irreparable bad blocks are read from a local LUN, the system uses data stored on the remote LUN to repair these bad blocks. B. If irreparable bad blocks are read from a local LUN, a read error message is returned to the host. C. If repairable bad blocks are read from a local LUN, data is returned to the host, ensuring fast host response. D. Before repairing bad blocks, the read permission must be obtained and the local read permission for active-active pairs must be confirmed.
