According to the relevant laws and regulations, which of the following descriptions of data loss prevention is wrong?

The engineer has set the WORM root directory according to the hospital's requirements, and all the subdirectories under this directory have the WORMattribute.

During the file protection period, no one can delete the protected file.

Protected Documents are Protected for a Period of 70 Years on Huawei OceanStor 9000 Storage Device.

WORM log save root, quota and WORM protection period cannot beset.

Provide file system-level snapshots, copy.

File System Snapshots, Scenarios, Replication, etc. Features are based on Storage Checkpoint.

3. True or False, In an OceanStor V3 system storage array, all the snapshots of a LUN occupy no more space than the LUN.

True

False

4. True or False, with aclient using the SMB 1.0/2.0/2.1/3.0 protocol to perform file replication inside a Huawei OceanStor 9000, it does not need to pass through the client, but can be done directly to the system.

True

False

5. Client1 needs to read file X from a Huawei OceanStor 900 and the node that responds to the read request is node A.

Based on this, which of the following are correct?

If the system has monitored the file X has been cached on Node B, the client client1 can read the file directly from Node

If the system monitors that node B has cached file X, then node A can read the file from node

After HUAWEI OceanStor 9000 processes the request for reading the file X from client1, the system reserves the message on bothnode A and node

If the system monitors that node A has cached file X, then node A only caches the data of file X and does not cache its verification data

OLTP database generally have a large number of random write, it is recommended to choose RAID 10 to store data.

In order to improve write performance, all SQL server database data stored in the LUN write strategy is configured to "write back the image".

Because the size of the SQL server page is 8K, in order to ensure the best performance of the database, NTFS allocated block size should not be less than 8K

SQL Server database instance memory size and recovery mode of choice has no effect on the performance of the database.

18. In the OceanStor VIS6600T dual-redundant switch network environment, using OceanStor Toolkit inspection found that "multi-path state detection "does not pass the inspection report.

Replacing the optical module of port 0 in slot A0 of node 0.

Replacing the light of the P0 port in the A0 slot of 0 node.

Replacing the optical module of the port connected to port 0 of the corresponding 0-node A0 slot on the switch.

20. 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?

In addition to path failover, multipathing also provides load balancing. Load balancing is the process of distributing I/O load across multiple physical paths.

In the event of a path failover, the virtual machine I/O delays Nintendo pump by 60s.

If the failover takes a long time to complete, the windows virtual machine may interrupt theI/O and eventually fail. To avoid this, set the windows virtual machine timeout to at least 30 seconds.

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.

114. Which of the following description of the infoLocker feature of Huawei's Ocenastor 9000 is incorrect?

To prevent changes in the directory or file protection time because of the changes in cluster time, a directory or file is configured with WORM attributes. After the directory or file will use the WORM clock to time, set the WORM clock. When the system will be based on the clock, user’s file will not be modified over the protection period.

If the cluster time is earlier than the WORM clock, the WORM clock will be chased every hour for up to 138 seconds to adjust. If the cluster is after the WORM clock, the WORM clock adjusts to the cluster time.

When a directory is configured as a WORM root directory, all subdirectories, new directories and new files in the directory automatically get the parent directory of WORM attributes. These attribute parameters can only be configured when the WORM root directory is set. Only then the user’s view can not be modified.

WORM logs are used to record the logs related to WORM operations and record them according to the time. The monthly log is a file that can be modified and can delete the file.
