Your multitenant container database, CDB1, is running in ARCHIVELOG mode and has two pluggable databases, HR_PDB and ACCOUNTS_PDB. An RMAN backup exists for the database.
You issue the command to open ACCOUNTS_PDB and find that the USERDATA.DBF data file for the default permanent tablespace USERDATA belonging to ACCOUNTS_PDB is corrupted.
What should you do before executing the commands to restore and recover the data file in ACCOUNTS_PDB?（）
A. Place CDB1 in the mount stage and then the USERDATA tablespace offline in ACCOUNTS_PDb.
B. Place CDB1 in the mount stage and issue the ALTER PLUGGABLE DATABASE accounts_pdb CLOSE IMMEDIATE command.
C. Issue the ALTER PLUGGABLE DATABASE accounts_pdb RESTRICTED command.
D. Take the USERDATA tablespace offline in ACCOUNTS_PDb.
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?（）
A. Use 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.
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 to restore 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.

Which three statements are true about the working of system privileges in a multitenant control database(CDB) that has pluggable databases (PDBs)?（）
You upgraded from a previous Oracle database version to Oracle Database version to Oracle Database12c. Your database supports a mixed workload. During the day, lots of insert, update, and deleteoperations are performed. At night, Extract, Transform, Load (ETL) and batch reporting jobs are run.The ETL jobs perform certain database operations using two or more concurrent sessions.After the upgrade, you notice that the performance of ETL jobs has degraded. To ascertain the cause ofperformance degradation, you want to collect basic statistics such as the level of parallelism, totaldatabase time, and the number of I/O requests for the ETL jobs.How do you accomplish this?（）
