B. BACKUP PLUGGABLE DATABASE PDB1 while connected to the PDB1 container
C. BACKUP DATABASE while connected to the PDB1 container

第4题:
RMAN enables you to open the target database when it is already mounted. Which command must you execute at the RMAN prompt to open the database?()
第5题:
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.
第6题:
A. The PDB must be open in read only mode.
B. The PDB must be dosed.
C. The unplugged PDB becomes a non-cdb.
D. The unplugged PDB can be plugged into the same multitenant container database (CDB)
E. The unplugged PDB can be plugged into another cdb.
F. The PDB data files are automatically removed from disk.
第7题:
Your multitenant container database (CDB) contains three pluggable database (PDBs). You find that the control file is damaged. You plan to use RMAN to recover the control file. There are no startup triggers associated with the PDBs.Which three steps should you perform to recover the control file and make the database fully operational?()
A. Mount the container database (CDB) and restore the control file from the control file auto backup.
B. Recover and open the CDB in NORMAL mode.
C. Mount the CDB and then recover and open the database, with the RESETLOGS option.
D. Open all the pluggable databases.
E. Recover each pluggable database.
F. Start the database instance in the nomount stage and restore the control file from control file auto backup.
