Huawei Huawei Certifications H13-624 Questions & Answers

• Question 91:

  In the Huawei dual-active disaster recovery solution, the peak write bandwidth of an application needs 10MB/s, and the average write bandwidth needs 200KB/s.

  The average write I/O volume is 4KB, and the bandwidth utilization rate is 70%. What is the bandwidth required for the application to deploy asynchronous remote replication?

  A. A.10MB/s

  B. B.200KB/s

  C. C.2.23MB/s

  D. D.114.3Mbit/s

  Correct Answer: C

• Question 92:

  The value of Huawei OceanStor 9000 InfoTier is reflected in:

  A. It can ensure the system's response speed to hot data access and improve the storage performance of the entire system.

  B. Comprehensively utilize the cost advantages of different storage media to effectively reduce deployment and maintenance costs.

  C. Improve system storage performance and realize intelligent data management.

  D. Realize automatic file migration according to the corresponding relationship between file attributes and different storage devices, reducing the cost and complexity of manual management.

  Correct Answer: ABCD

• Question 93:

  The OceanStor backup solution architecture includes three parts: the central site, branch sites, and remote backup sites. Only the backup system can be deployed at the backup site, not the production system.

  A. True

  B. False

  Correct Answer: B

• Question 94:

  When selecting the type of data backup, which option is wrong in the following description?

  A. If there are only cumulative incremental backups in the schedule, but no full backups, when performing cumulative incremental backups for the first time, all files will be backed up pieces.

  B. It is recommended to use a combination of three backup types: full backup, differential incremental backup, and cumulative incremental backup.

  C. If the backup strategy is full backup combined with differential incremental backup, after a system failure, if you want to restore to the most recent data, then It is necessary to restore the data of the last full backup and all differential incremental backups after the full backup.

  D. Differential incremental can save storage space to the greatest extent, and the backup window is small.

  Correct Answer: B

• Question 95:

  There are 1040GB files that need to be backed up, the backup window is 6 hours, and the GE network and media end deduplication, then the following statement is correct Yes: (multiple choice)

  A. Optional LAN-Base networking

  B. The required bandwidth is 61.6MB/s

  C. The required bandwidth is 71.7MB/s

  D. Must use LAN-Free networking\

  Correct Answer: AB

• Question 96:

  (Judgment) Through the Huawei OceanStor 9000 Device Manager, we can view the real- time OPS performance indicators of the system.

  A. True

  B. False

  Correct Answer: A

• Question 97:

  The cascading replication disaster recovery solution establishes a cascading replication relationship for the storage devices used by the business to achieve intra-city disaster recovery + remote disaster recovery, with little impact on the performance of the production center.

  A. True

  B. False

  Correct Answer: A

• Question 98:

  Which of the following are typical application scenarios of Huawei's active-active disaster recovery solution? (multiple choice)

  A. Oracle RAC application

  B. SQL Server application

  D. FusionSphere application

  Correct Answer: ABCD

• Question 99:

  In the following description of the asynchronous remote replication of the OceanStor V3 storage array, which one is wrong?

  A. During asynchronous remote replication, after the master LUN write I/O is successful, the master array returns the write I/O success to the host.

  B. After creating an asynchronous remote replication relationship, you need to do an initial synchronization.

  C. When adding a secondary LUN for asynchronous remote replication, the system automatically creates and activates the snapshot of the primary and secondary LUNs.

  Correct Answer: C

• Question 100:
