A.creating a database link from CDB$ROOT in the local database to the PDB in the remote system that is to be cloned

B.creating a database link from CDB$ROOT in the local database to CDB$ROOT in the remote system that is to be cloned

C.creating a database link from CDB$ROOT in the remote database to the PDB in the local database

D.opening the cloned PDB

E.creating a new empty PDB in the local database from PDB$SEED

F.creating a database link from CDB$ROOT in the remote database to be cloned to CDB$ROOT in the local database

G.automatically dropping the database link to the remote database if it already exists

A.If an RMAN BACKUP VALIDATE command takes noticeably less time than an actual backup, then write I/O is a likely bottleneck.

B.Data files with a high value in V$BACKUP_SYNC_IO.DISCRETE_BYTES_PER_SECOND are a potential performance bottleneck when synchronous I/O is used.

C.If an RMAN BACKUP VALIDATE command takesroughly the same time as an actual backup, then both read and write I/O are likely bottlenecks.

D.Data files with a high value in V$BACKUP_ASYNC_IO.SHORT_WAITS are a potential performance bottleneck when asynchronous I/O is used.

E.If an RMAN BACKUP VALIDATE command takesroughly the same time as an actual backup, then read I/O is a likely bottleneck.F

A.ata Recovery Advisor can be used if a database is in the NOMOUNT state.

B.A failure can be closed only if the database is in MOUNT state.

C.Using the Data Recovery Advisor LIST FAILURE command always requires that the database for which failures are to be listed is in MOUNT state.

D.Data Recovery Advisor can be used if a database is closed.

E.Data Recovery Advisor can proactively check for failures.

A.The database must have FLASHBACK DATABASE ON to perform Database Point-in-Time Recovery.

B.The database must be in MOUNT state when performing Database Point-in-Time Recovery.

C.Database Point-in-Time Recovery is performed by the Managed Recovery Process (MRP)

D.The Database must be in ARCHIVELOG mode.

E.The target point for the recovery must be specified as a stime or System Change Number (SCN).

F.The database must be open RESETLOGS after Database Point-in-Time Recovery.

A.The target database control file is synchronized from the recovery catalog with a partial resync at the next backup.

B.The recovery catalog is synchronized from the target database control file with a full resync at the next backup.

C.The recovery catalog is synchronized from the target database control file with a partial resync at the next backup.

D.The target database control file is synchronized from the recovery catalog with a full resync at the next backup.
