Question 231

Your database is configured in ARCHIVELOGmode.
Examine the RMAN configuration parameters:

Examine the command:
RMAN> BACKUP DATABASE PLUS ARCHIVELOG DELETE INPUT;
What is the outcome?

A.It fails because the DELETE INPUToption can be used only with the BACKUP ASBACKUPSET command.

B.It executes successfully and creates a backup set of the database along with archived log files and then deletes the original archived log files.

C.It executes successfully and creates an image copy of the database along with archive log files and then deletes the original archived log files.

D.It fails because the DELETE INPUToption can be used only with the BACKUP AS COPYcommand.

Question 232

What is the effect of specifying the "ENABLE PLUGGABLE DATABASE" clause in a "CREATE DATABASE" statement?

A.It will create a multitenant container database (CDB) with only the root opened.

B.It will create a CDB with root opened and seed read only.

C.It will create a CDB with root and seed opened and one PDB mounted.

D.It will create a CDB that must be plugged into an existing CDB.

E.It will create a CDB with root opened and seed mounted.

Question 233

An application repeatedly accesses small lookup tables, causing a lot of physical I/O operations.
What do you recommend to minimize this?

A.Configure the KEEP buffer cache and alter the tables to use the KEEP cache.

B.Configure the RECYCLE buffer cache and alter the tables to use the RECYCLE cache.

C.Configure the nonstandard buffer cache with a buffer size greater than the size of the default buffer
cache.

D.Increase the size of the shared pool

Question 234

In your database instance, the UNDO_RETENTIONparameter is set to 1000and undo retention is not guaranteed for the fixed size undo tablespace.
Which statement is true about undo retention?

A.Inactive undo is retained for at least 1000 seconds if free undo space is available.

B.Undo becomes expired obsolete after 1000 seconds.

C.Inactive undo is retained for 1000 seconds even if new transactions fall due to lack of space in the undo tablespace.

D.Undo is retained in the UNDO tablespace for 1000 seconds, and then moved to the SYSTEM tablespace to provide read consistency.

Question 235

Examine the structure of the SALES table, which is stored in a locally managed tablespace with Automatic Segment Space Management (ASSM) enabled.

You want to perform online segment shrink to reclaim fragmented free space below the high water mark.
What should you ensure before the start of the operation?

A.Row movement is enabled.

B.No queries are running on this table.

C.Extra disk space equivalent to the size of the segment is available in the tablespace.

D.Referential integrity constraints for the table are disabled.

E.No pending transaction exists on the table.
