A.It can be used to install and upgrade Oracle Database for single-instance and cluster configurations.

B.It uses a single RPM that automatically extracts and installs the Oracle Database software.

C.It can only install and configure Oracle Database software. The database has to be created separately.

D.It does not require the setup wizard.

E.It can be used for both Oracle Database and Oracle Grid Infrastructure installation.

A.Automatic block repair can repair blocks with no standby database if db_block_checking = TRUE.

B.Real-Time Query must be enabled on a physical standby database for automatic block repair to be done on its primary database.

C.Real-Time Query must be enabled on a physical standby database for automatic block repair to be done on that physical standby database.

D.It is not possible for media corrupt blocks.

E.Real-Time Query must be enabled on a primary database for automatic block repair to be done on any of its physical standby databases.

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

B.Setting DBWR_IO_SLAVES to a non zero value can improve backup performance when using synchronous I/O.

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

D.If an RMAN BACKUP VALIDATE command takes roughly the same time as an actual backup, then read I/O is a likely bottleneck.

E.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.

F.Setting DBWR_IO_SLAVES to a non zero value can improve backup performance when using asynchronous I/O/

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

C.Control file backups can be created while connected to CDB$ROOT.

D.Online Redo Log backups can be created while connected to CDB$ROOT

E.The BACKUP TABLESPACE command can back up a pDB tablespace even if RMAN is connected to CDB$ROOT.

A.PDB1 and PDB2 are in read only state.

B.CDB$ROOT is in mount state.
