Which of the following statement about RAID 2.0 is correct?(Multiple choice.)

• A.A CKG chunk may come from the same hard disk.
• B.The hard disk is divided into chunks.
• C.Lun consists of extend or grain
• D.Chunk in a CKG may come from a different storage pool.

Database applications are one of the important applications supporting storage arrays.
Differentapplication configurations and parameter settings may affect the service performance. In order to store arrays (such as OceanStor V3 series storage) with SQL server applications with the best performance, which of the following statements is wrong:

• A.SQL Server database instance memory size and recovery mode of choice has no effect on the performance of the database.
• B.In order to improve write performance, all SQL server database data stored in the LUN write strategy is configured to "write back the image".
• C.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 8KB.
• D.OLTP database generally have a large number of random write, it is recommended to choose RAID 10 to store data.

True or False, one project adopts the OceanStor 18500 toachieve the performance of 50,000 IOPS. Enable the SmartTier feature and configure the Layer 3 Tier configuration disk computing, high-performance layer up to
30,000 IOPS, the performance layer can reach 20,000 IOPS, capacity can reach 10,000 IOPS. This configuration will certainly be able to meet the project's 50,000 IOPS needs.

• A.True
• B.False

Which of the following best practice descriptions of Oralce database is correct? (Multiple choice.)

• A.If the database OLTP business log write is very frequent, it is recommended that the appropriate online log file up, but it is recommended not to exceed 128MB.
• B.OLAP business query output is usually astatistical value (using group by with order by), so you can set a larger SGA-target value (relative to OLTP).
• C.In Windows2008 or windows2012 operating system environment, in order to improve I / O processing efficiency, MBR partition is created, and diskpart command is recommended to set the partition alignment.
• D.It is recommended to use UDEV UUID and drive letter binding, in Linux environment configuration Oracle database, to avoid subsequent maintenance letter changes caused by the database which can not start.

Oracle database normally starts the opening state of the process. Which files must it read? (Multiple choice.)

• A.Control Documents
• B.Data files
• C.Archive log file
• D.Parameter file
