Question 91

Examine this configuration:
1. The ORCLdatabase data files are in Automatic Storage Management (Oracle ASM) disk group +DATA.
2. ORCLuses disk group +FRAfor the Fast Recovery Area.
3. LISTENER is the listener for ORCL.
4. The database, listener, ASM instance, and ASM disk groups are managed by Oracle Restart.
5. All components are currently shut down.
You execute this command:

What is the outcome?

A.Only the ORCLdatabase instance and the +DATAand +FRAdisk groups are started.

B.Only the ORCLdatabase and the ASM instances are started.

C.The ORCL database, the Oracle ASM instances, the +DATAand +FRAdisk groups, and the LISTENER are started.

D.Only the ORCLdatabase instance, the Oracle ASM instance, and the +DATAand +FRAdisk groups are started.

E.Only the ORCL database instance is started.

Question 92

choose two You take your database backups by using the RMAN media management interface (MMI). Which two are true about the use of the RMAN MMI?

A.You can

B.You can

C.You can

D.You can

E.You can

Question 93

Which two are true about duplicating pluggable databases (PDBs) with RMAN? (Choose two.)

A.A user with SYSDBA or SYSBACKUP must be logged in with RMAN to the PDB to duplicate it.

B.CDB$ROOT and PDB$SEED are automatically duplicated.

C.The auxiliary instance is automatically created with ENABLE_PLUGGABLE_DATABASE = TRUE.

D.Two or more PDBs can be duplicated with the same RMAN DUPLICATE command.

E.All tablespaces belonging to a PDB must be duplicated when duplicating the PDB.

Question 94

Which two are true about instance recovery? (Choose two.)

A.It is performed automatically while the database remains in MOUNT state. Then the database is opened.

B.It is not possible if an archived log is missing.

C.It is performed by the Recovery Writer (RVWR) background process.

D.Setting FAST_START_MTTR_TARGET to a higher value reduces instance recovery time by causing the log writer to write more frquently, thereby reducing the number of I/Os needed during instance recovery.

E.It is performed automatically after the database is opened; however, blocks requiring recovery are not available until they are recovered.

F.Setting FAST_START_MTTR_TARGET to a lower value reduces instance recovery time by causing dirty buffers to be written to disk more frequently, thereby reducing the number of I/Os needed during instance recovery.

Question 95

Choose two. Your database is in ARCHIVELOG mode and you plan to use Flashback Database. Which two features or parameters manage space availability in the fast recovery area?

A.the archived log deletion policy

B.the backup optimization policy

C.the DB_CREATE_ONLINE_LOG_DEST_n parameter setting

D.using guaranteed UNDO retention

E.the DB_RECOVERY_FILE_DEST parameter setting

F.the backup retention policy
