• 2You are administering a database stored in Automatic Storage Management (ASM). Youuse RMAN to back up the database and the MD_BACKUP command to back up the ASMmetadata 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、

  A.Use the MD_RESTORE command to restore metadata for an existing disk group bypassing the existing disk group name as an input parameter and use RMAN to restore the data.

  B.Use the MKDG command to restore the disk group with the same configuration as the backed-up disk group and data on the disk group.

  C.Use 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 torestore the data.

  D.Use 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.

  E.Use the MD_RESTORE command to restore both the metadata and data for the failed disk group.

  F.Use 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.

• 5Your multitenant container (CDB) contains two pluggable databases (PDB), HR_PDB andACCOUNTS_PDB, both of which use the CDB tablespace. The temp file is called temp01.tmp.A user issues a query on a table on one of the PDBs and receives the following error:ERROR at line 1:ORA-01565: error in identifying file ‘/u01/app/oracle/oradata/CDB1/temp01.tmp’ORA-27037: unable to obtain file statusIdentify two ways to rectify the error.

  A.Add a new temp file to the temporary tablespace and drop the temp file that that produced the error.

  B.Shut down the database instance, restore the temp01.tmp file from the backup, and then restart the database.

  C.Take the temporary tablespace offline, recover the missing temp file by applying redo logs, and then bring the temporary tablespace online.

  D.Shutdown the database instance, restore and recover the temp file from the backup, and then open the database with RESETLOGS.

  E.Shut down the database instance and then restart the CDB and PDBs.
