• Question 211:

  Which of the read and write strategies of Huawei Oceanstor V3 storage system is correct?

  A. Read and write strategies include permanent, default, recycling.
  B. Recycling strategy is suitable for business scenarios that require high performance and small amount of data.
  C. Select out the recycling strategy when the data or write data is the lowest priority.
  D. Resident strategy is suitable for large read and write data, and read-only scenes.
  A. Read and write strategies include permanent, default, recycling.

• Question 212:

  In simpana backup software, incremental backup means _______.

  A. The data that has changed since the last backup is backed up.
  B. Changed data backup since last full backup.
  C. Full backup of all data.
  D. After the initial backup data backup of all data.
  A. The data that has changed since the last backup is backed up.

• Question 213:

  Maintaining a persistent connection between host and storage, ESXi must support multipathing. Which of the following statements is incorrect regarding multipathing for VMware vSphere 5.5?

  A. In addition to path failover, multipathing also provides load balancing. Load balancing is the process of distributing I / O load across multiple physical paths.
  B. In the event of a path failover, the virtual machine I / O delays Nintendo pump by 60s.
  C. If the failover takes a long time to complete, the windows virtual machine may interrupt the I / O and eventually fail. To avoid this, set the windows virtual machine timeout to at least 30 seconds.
  D. When coordinating vmware NMP and any installed third-party MPP, the PSA (Pluggable Storage Architecture) performs load and unload multipathing plug-ins and handles physical path discovery and removal.
  C. If the failover takes a long time to complete, the windows virtual machine may interrupt the I / O and eventually fail. To avoid this, set the windows virtual machine timeout to at least 30 seconds.

• Question 214:

  Create LUNs on an OceanStor V3 storage system. Set the initial space allocation policy to be automatic. Create LUN 1, and 80% of its space comes from the capacity tier. Create LUN 2 in the same storage pool. It can be concluded that 0% of LUN 2's space comes from the performance tier.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 215:

  In a media application scenario, large files is an important application feature. Huawei OceanStor 9000 can allocate different configurations according to different users. This avoids some of the unimportant data transition overhead, which of the following description of the quota is correct?

  A. The types of quotas include capacity quota and file quota.
  B. Quota methods include calculating quotas, soft quotas and mandatory quotas.
  C. The system pre-allocates quotas for files before writing the file. When the user cancels the writing of the file being written, the system does not release a pre-allocated quota.
  D. When the user continues to write data, the quota information has been used in the InfoAllocator interface real-time updates.
  A. The types of quotas include capacity quota and file quota.

• Question 216:

  Which of the following is a description of the UltraPath multipath setting? (Multiple answers)

  A. The mode of operation of the array can be in-controller load balancing or inter-controller load balancing.
  B. Load Balancing Mode Including wheel training algorithm, the maximum queue depth algorithm, the maximum workload algorithm.
  C. After the connection is interrupted between the LUN home controller and the host, the host accesses the LUN through the peer controller. In this case, the over-trail software defaults the switched home controller of the LUN to the remote controller.
  D. When multipath detects a preferred controller failure recovery, the I / O is resumed immediately at the preferred controller by default.
  A. The mode of operation of the array can be in-controller load balancing or inter-controller load balancing.
  C. After the connection is interrupted between the LUN home controller and the host, the host accesses the LUN through the peer controller. In this case, the over-trail software defaults the switched home controller of the LUN to the remote controller.
