Huawei H13-622 Online Questions & Answers

• Question 81:

  In a NetBackup-based N8500 file system backup network, all the nodes of the N8500 must be connected to both the NetBackup master server and media servers.

  A. True
  B. False
  B. False

• Question 82:

  Which of the following are not functions of OMS? (Choose all that apply.)

  A. Alarm reporting
  B. Performance reporting
  C. Tenant management
  D. Device monitoring
  A. Alarm reporting
  B. Performance reporting
  D. Device monitoring

• Question 83:

  Which of the following statements about the performance optimization check items of the N8500 clustered NAS storage systems are correct? (Select three)

  A. Check whether the BBUs are faulty. If only one BBU is faulty, the current write policy of LUNs changes to write through.
  B. Log in to the ISM and check whether alarms indicating slow disk response exist.
  C. Check on the ISM whether bit errors exist on Fibre Channel ports.
  D. Check whether front-end service ports are functioning at the optimal rate. For example, check whether the port rate is 4 Gbit/s when the bandwidth is 8 Gbit/s.
  B. Log in to the ISM and check whether alarms indicating slow disk response exist.
  C. Check on the ISM whether bit errors exist on Fibre Channel ports.
  D. Check whether front-end service ports are functioning at the optimal rate. For example, check whether the port rate is 4 Gbit/s when the bandwidth is 8 Gbit/s.

• Question 84:

  Which of the following about WushanFS global cache technology employed by Huawei OceanStor 9000 is false?

  A. WushanFS global cache enables the memory spaces on all storage servers to logically form a unified memory resource pool.
  B. Data cached on a node cannot be hit by the read/write service of another node.
  C. Global cache helps improve the sharing of memory resources among nodes.
  D. The WushanFS uses a distributed lock mechanism to implement global management of cached data. The same service data is cached only on one node. Another node that needs to access the service data can apply for a lock to obtain the cached data.
  B. Data cached on a node cannot be hit by the read/write service of another node.

• Question 85:

  Which of the following statements about the indicators on an N8500 clustered NAS system are correct? (Select two.)

  A. A power module runs properly if its indicator is steady red.
  B. The system is being started if the power indicator on the NAS service module blinks green.
  C. The data transmission rate is 4 Gbit/s if the port indicator on the NAS service 10GE interface card is steady blue.
  D. Data is being transmitted if the Active indicator of the management network port blinks orange.
  B. The system is being started if the power indicator on the NAS service module blinks green.
  D. Data is being transmitted if the Active indicator of the management network port blinks orange.

• Question 86:

  In an N8500 clustered NAS system, underlying virtualization is implemented by the VxVM component. The virtual objects managed by the VxVM are VM disks, disk groups, subdisks, and plexes. Which of the following statements is incorrect?

  A. A VM disk is controlled by the VxVM and typically located in a disk group. Each VM disk corresponds to at least one physical disk or disk partition.
  B. A disk group is a collection of VM disks.
  C. A subdisk is the basic unit for the VxVM to allocate disk space. To improve the efficiency of underlying resource use, a subdisk can be a group of inconsecutive disk blocks.
  D. A plex consists of one or multiple subdisks on one or multiple physical disks. Each plex contains a duplicate of the data selected in a volume.
  C. A subdisk is the basic unit for the VxVM to allocate disk space. To improve the efficiency of underlying resource use, a subdisk can be a group of inconsecutive disk blocks.

• Question 87:

  Based on full interconnection of data channels and communication channels, a clustered NAS system employs cluster volume management to manage storage space globally. All nodes in the cluster can access the same storage space using the same volume device name, ensuring block device access consistency.

  A. TRUE
  B. FALSE
  A. TRUE

• Question 88:

  If an application server cannot access the storage resources of an N8500 storage system, which of the following operations can be performed for troubleshooting? (Select three.)

  A. Log in to the ISM to check alarms.
  B. Check the indicators on the storage system.
  C. Reinstall the ISM software.
  D. Restart the sharing service.
  A. Log in to the ISM to check alarms.
  B. Check the indicators on the storage system.
  D. Restart the sharing service.

• Question 89:

  Which of the following statements about the file system planning of the N8500 clustered NAS storage systems are correct? (Select two)

  A. A file system has at most 10 million files.
  B. A directory has at most 10,000 files.
  C. A file system has at most 10 levels of directories.
  D. A file system has at most 10,000 directories.
  B. A directory has at most 10,000 files.
  C. A file system has at most 10 levels of directories.

• Question 90:

  Which of the following statements about the InfoLocker feature of Huawei OceanStor 9000 is false?

  A. WORM files can be modified and deleted.
  B. A WORM clock can be set only once, and it cannot be modified later.
  C. If a directory is configured as a WORM root directory, all existing subdirectories as well as newly created subdirectories and files under the directory automatically obtain as a WORM attributes of the directory.
  D. WORM protection can be submitted only in an automatic manner.
  A. WORM files can be modified and deleted.
