Which of the following is incorrectly described in the Huawei OceanStor 9000 file pool policy?

• A.The create policy is used to determine the initial placement of the file when creating the file system file.
  The policy conditions include the storage path, the file name, and
  UID/GID
• B.The load balancing strategy can be based on: CPU, memory, bandwidth, network connections, node capability values
• C.Oceanstor 9000 load balancing service support; round robin mode, CPU usage, number of node connections
• D.You can classify nodes as needed. For each partition load balancing system, you can configure independent load policies and independent access to domain names.

If the name of a shared directory is dirtest in an OceanStor 9000 storage system, local users who have permission can access the directory by entering \\*.*.*.*\dirtest, where *,*.*,* must be the front-end service IP address of the node that provides storage space for the dirtest directory.

• A.True
• B.False

On the Linux client that accesses the Huawei OceanStor 9000 cluster, you can adjust the client parameters to improve access performance. The following errors occur.
Which one is it?

• A.Turning on jumbo frames can reduce TCP loss and improve performance. The premise is to confirm the client interface from the Oceanstor 9000 front-end network interface channel.
  Jumbo frames must be supported by all network devices
• B.In order to support jumbo frames, all nodes of the corresponding Oceanstor 9000 need to be set at the same time.
• C.NFS uses the TCP protocol to send and receive data, and appropriately increase the buffer size to speed up TCP transmission.
• D.Oceanstor9000 supports jumbo frames. It is necessary to set the MTU of all front-end service network ports.

Which of the following statements about different service applications' storage performance and capacity requirements are correct?

• A.Compared with picture and video applications, a large-sized relational database requires a larger storage capacity.
• B.Compared withan email application, an enterprise OLTP/OLAP database requires higher storage performance.
• C.Compared with a real-time online service system, scientific computing requires higher storage performance.
• D.Compared with the content delivery network application, the backup and archive services require higher storage performance.

In an N8500 system, if an engine node is faulty and the other components are in the normal state, the consequences do not include which of the following?

• A.Service performance deteriorates.
• B.The N8500 cannot be managed.
• C.The NFS file sharing service becomes abnormal.
• D.LUNson the storage units become unavailable.
