• Question 23:

  The following description of the principles of making a backup strategy is wrong:

  A. Measure the frequency of data backup based on the importance of the data

  B. Measure task execution time based on the amount of data change

  C. Measure the data retention period based on the amount of data

  D. Measure backup media based on the discreteness of data

  Correct Answer: D

• Question 24:

  Which of the following is the correct power-on sequence of the Huawei OceanStor 9000 big data storage system?

  A. Cabinet-->Switch-->KVM--->Node

  B. Cabinet-->KVM-->Switch--->Node

  C. Cabinet-->Switch-->Node--->KVM

  D. Cabinet-->Node-->KVM--->Switch

  Correct Answer: A

• Question 25:

  During data backup, in order to save space, single-selection data may be deduplicated, such as repeated data block A and For block B, only one copy of data is physically saved, and the index corresponding to block A or B will be deleted.

  A. True

  B. False

  Correct Answer: B

• Question 26:

  After testing, the bandwidth of the two data centers of the customer is 155Mbit/s, the peak write bandwidth of an application is 9.8MB/s, and the average The write bandwidth is 300KB/s, the average write I/O size is 4KB., and the bandwidth utilization rate is 70%. Colleagues choose active and standby synchronous remote replication for disaster recovery Scheme, the scheme:

  A. Not feasible, 200Mbit/s is required to calculate the bandwidth.

  B. Not feasible. The primary and standby synchronous remote replication disaster recovery solution requires that the bandwidth utilization rate must be >80%.

  C. Not feasible. The primary and standby synchronous remote replication disaster recovery solution requires that the write I/O size must be less than 2KB.

  D. Feasible, because the conditions meet the requirements of the primary and standby synchronous remote replication disaster recovery program.

  Correct Answer: D

• Question 27:

  Send a control command through the backup server, first take a snapshot (or other similar operations) of the data volume that needs to be backed up, Make a copy, then use the backup server to mount the snapshot volume, and use the backup server to back up the data on this volume to the backup On the device. What type of backup networking is described in the above workflow?

  A. LAN-Base

  B. LAN-Free

  C. Server-Less

  D. Server-Free

  Correct Answer: C

• Question 28:

  In the Huawei OceanStor 9000, which of the following is not an authentication method supported by NFS sharing?

  A. NIS authentication

  B. LDAP authentication

  C. Client IP address/host name authentication

  D. Local user authentication

  Correct Answer: D

• Question 29:

  Regarding the storage layer data replication disaster recovery technology, which of the following statements is correct?

  A. Install dedicated data replication software on the server.

  B. Reduce the impact on server performance: Compatibility requirements are relatively high, and options are small.

  C. Mature technology, large selection area, small connection distance limit, and high stability.

  D. Less investment and good compatibility. Affect server performance.

  Correct Answer: C

• Question 30:

  Huawei's end-to-end active-active data center solution is divided into 6 logical levels, namely storage layer, computing layer, application layer, and network layer. Network layer, transport layer and security layer, the design points of each layer include: (multiple choice)

  A. The security layer provides security protection functions such as FW and IDS of the data center through the Huawei USC series.

  B. The storage layer optimizes the standard 1 write I/O 2 round trips to 1 round trip through the FastWrite function to improve write performance.

  C. The computing layer adopts virtualization platforms such as Huawei FusionSphere and VMware to provide cross-data center large cluster technology to meet the needs of enterprises A variety of key business dual-active requirements.

  D. The transmission layer uses dispersion compensation and other tuning methods to ensure the minimum delay of the transmission layer.

  Correct Answer: ABCD
