多选题You support Oracle Database 12c Oracle Database 11g, and Oracle Database log on the same server. All databases of all versions use Automatic Storage Management (ASM). Which three statements are true about the ASM disk group compatibility attributes that are set for a disk group?（）AThe ASM compatibility attribute controls the format of the disk group metadata.BRDBMS compatibility together with the database version determines whether a database Instance can mount the ASM disk group.CThe RDBMS compatibility setting allows only databases set to the same version as the compatibility value, to mount the ASM disk group.DThe ASM compatibility attribute determines some of the ASM features that may be used by the Oracle disk group.EThe ADVM compatibility attribute determines the ACFS features that may be used by the Oracle 10g database.
考题
多选题You are administering a database stored in Automatic Storage Management (ASM). You use RMAN to back up the database and the MD_BACKUP command to back up the ASM metadata regularly. You lost an ASM disk group DG1 due to hardware failure. In which three ways can you re-create the lost disk group and restore the data?（）AUse the MD_RESTORE command to restore metadata for an existing disk group by passing the existing disk group name as an input parameter and use RMAN to restore the data.BUse the MKDG command to restore the disk group with the same configuration as the backed-up disk group and data on the disk group.CUse the MD_RESTORE command to restore the disk group with the changed disk group specification, failure group specification, name, and other attributes and use RMAN to restore the data.DUse the MKDG command to restore the disk group with the same configuration as the backed-up disk group name and same set of disks and failure group configuration, and use RMAN to restore the data.EUse the MD_RESTORE command to restore both the metadata and data for the failed disk group.FUse the MKDG command to add a new disk group DG1 with the same or different specifications for failure group and other attributes and use RMAN to restore the data.

单选题Your multitenant container database (CDB) contains pluggable databases (PDBs), you are connected to the HR_PDB. You execute the following command: SQL CREATE UNDO TABLESPACE undotb01 DATAFILE ‘u01/oracle/rddb1/undotbs01.dbf’ SIZE 60M AUTOEXTEND ON; What is the result?（）A
It executes successfully and creates an UNDO tablespace in hr_pdb.B
It falls and reports an error because there can be only one undo tablespace in a cdb.C
It fails and reports an error because the CONTAINER=ALL clause is not specified in the command.D
It fails and reports an error because the CONTAINER=CURRENT clause is not specified in the command.E
It executes successfully but neither tablespace nor the data file is created.
考题
单选题Examine the parameter for your database instance: You generated the execution plan for the following query in the plan table and noticed that the nested loop join was done. After actual execution of the query, you notice that the hash join was done in the execution plan: Identify the reason why the optimizer chose different execution plans.（）A
The optimizer used a dynamic plan for the query.B
The optimizer chose different plans because automatic dynamic sampling was enabled.C
The optimizer used re-optimization cardinality feedback for the query.D
The optimizer chose different plan because extended statistics were created for the columns used.

多选题Which two statements are true about Oracle Managed Files (OMF)?（）AOMF cannot be used in a database that already has data files created with user-specified directions.BThe file system directions that are specified by OMF parameters are created automatically.COMF can be used with ASM disk groups, as well as with raw devices, for better file management.DOMF automatically creates unique file names for table spaces and control files.EOMF may affect the location of the redo log files and archived log files.
