Q51. For OceanStor V3 SmartMigration function: The capacity of the target LUN can be smaller than that of the source LUN, as long as the available capacity is sufficient.

Q52. Which load balancing method does the Huawei Oceanstor 9000 InfoEqualize feature not support?

Q53. What information must be collected before deploying a DR solution? (Multiple Choice)

Q54. In Huawei distributed storage, the block service asynchronous remote replication architecture is based on the block service cluster to build an asynchronous replication relationship. Based on the difference data, the data of the master and slave volumes are periodically synchronized. From the data synchronization of the last synchronization cycle completes to the current synchronization starts, all data generated on the master volume will be written to the slave volume during this synchronization.

Q55. OceanStor CloudService is a professional remote maintenance system that monitors customer’s device alarms around the clock.

Q56. The intelligent load balancing technology in Huawei’s distributed storage supports partitions, and each partition can set an independent domain name and load balancing strategy.

Q57. What are the values of recovery point objective (RPO) and recovery time objective (RTO) in Huawei synchronous remote replication?

Q58. Which of the following is wrong description of the characteristics of Oceanstor 9000 InfoStamaper?

Q59. Suppose that a customer that adopts the Huawei Network-Layer Full-Sized Snapshot Solution creating a snapshot for the source volume at 9:00 am, and the snapshot finishes being created at 9:10 am. During the snapshot creation, some data is written to the source volume.
Based on the preceding conditions, which of the following statements is correct?

Q60. HyperMetro uses cross-site real-time data mirroring to ensure real-time data synchronization between the storage arrays at two sites. Upon receiving a write I/O, the storage array in a data center generates a write log. In the log, only address information is recorded, but data is not recorded. To ensure performance, log information is recorded in memory space capable of power failure protection.

Q61. Which of the following types of intermediate links can be used in Huawei’s disaster recovery dual-active solution? (Multiple choice)

Q62. Highway reconstruction project A uses Huawei’s Hyper-converged Storage LightDC ROBO branch solution. Which of the following options reflects the advantages of this solution? (Multiple choice)

Q63. An enterprise’s business data is stored in two data centers, and storage devices from different vendors are deployed. SmartVirtualization can be used to host the original LUNs on the heterogeneous storage system in each data center and create eDevLUNs, and then create eDevLUNs and other storage devices. Asynchronous remote replication between local LUNs on the Huawei storage system at one site realizes data disaster recovery between sites.

Q64. The HyperLock (WORM) feature of Huawei Storage enables files to be written only once, cannot be written repeatedly, and cannot be modified, deleted, or renamed.

Q65. Operation and maintenance are based on technology and provide higher-quality services through technical guarantee products. Which of the following aspects can be used to improve the quality of operation and maintenance? (Multiple choice)

Q66. At Oceanstor 9000, Huawei adopted the Scale-out for the characteristics of big data to architecture and use the big data storage platform launched through X86 architecture hardware.

Q67. Huawei’s end-to-end active-active data center solution is divided into 6 logical levels, namely storage layer, computing layer, application layer, network layer, transmission layer, and security layer. What are the design points of each layer? (Multiple choice)

Q68. In the era of big data, traditional technology upgrades can no longer meet the needs of big data processing. Which of the following is not the direction of technology development in the era of big data?

Q69. Regarding CIFS share configuration, which of the following options is incorrect?
