Your multitenant container database has three pluggable databases (PDBs): PDB1, PDB2, and PDB3.Which two RMAN commands may be; used to back up only the PDB1 pluggable database?() A. BACKUP PLUGGABLE DATABASE PDB1 while connected to the root containerB. BACKUP PLUGGABLE DATABASE PDB1 while connected to the PDB1 containerC. BACKUP DATABASE while connected to the PDB1 containerD. BACKUP DATABASE while connected to the boot containerE. BACKUP PLUGGABLE database PDB1 while connected to PDB2
Which two statements are true concerning the Resource Manager plans for individual pluggabledatabases (PDB plans) in a multitenant container database (CDB)?() A. If no PDB plan is enabled for a pluggable database, then all sessions for that PDB are treated to an equal degree of the resource share of that pdb.B. In a PDB plan, subplans may be used with up to eight consumer groups.C. If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups across all PDBs in the cdb.D. If no PDB plan is enabled for a pluggable database, then the PDB share in the CDB plan is dynamically calculated.E. If a PDB plan is enabled for a pluggable database, then resources are allocated to consumer groups based on the shares provided to the PDB in the CDB plan and the shares provided to the consumer groups in the PDB plan.
Which statement is true concerning dropping a pluggable database (PDB)?() A. The PDB must be open in read-only mode.B. The PDB must be in mount state.C. The PDB must be unplugged.D. The PDB data files are always removed from disk.E. A dropped PDB can never be plugged back into a multitenant container database (CDB).
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.
