Question 1.
You observe that a database performance has degraded over a period of time. While investigating the reason, you find that the size of the database buffer cache is not large enough to cache all the needed data blocks. 

Which advisory component would you refer to, in order to determine that required size of the database buffer cache?

A. Memory Advisor
B. Segment Advisor
C. SQL Tuning Advisor
D. SQL Access Advisor
E. Automatic Database Diagnostic Monitor (ADDM)

Answer: A

Question 2.

Exhibit:
 
In your production database, the total waits and the time waited for log file parallel write are significantly high. While investigating the reason, you find that there are three redo log groups with two members in each group, and all redo log members are places on a single physical disk.

What action would you take to minimize the waits?

A. start the log writer slave processes
B. increase the number of redo log files
C. increase the size of the redo log buffer
D. place the redo log files on the different disks
E. increase the number of log writer processes

Answer: D

Question 3.
One of the tablespaces is read-only in your database. The loss of all control files forced you to re-create the control file.

Which operation do you need to perform after re-creating the control file and opening the database?

A. drop and re-create the read-only tablespaces
B. rename the read-only data files to their correct file names
C. change the tablespace status from read/write to read-only
D. re-create the read-only tablespace because it is automatically removed

Answer: B

Question 4.
You have set some of the initialization parameters as:
DB_BLOCK_SIZE = 8KB
SGA_MAX_SIZE = 2GB
SGA_TARGET = 0
SHARED_POOL_SIZE = 120MB
DB_CACHE_SIZE = 896MB
STREAM_POOL_SIZE = 0
LARGE_POOL_SIZE = 110 MB

Which two statements are correct? (Choose two.)

A. You cannot set a value for the DB_8K_CACHE_SIZE parameter.
B. If you increase the size of the large pool to 120 MB, then the memory allocated to the shared 
    poll will be reduced to 110 MB.
C. If the value for SGA_TARGET is changed to 1 GB and SHARED_POOL_SIZE is set to 120 
    MB, then memory cannot be taken from the shared pool, even if the shared pool has free 
    space available.
D. If an application attempts to allocate more than 120 MB from the shared pool and free space is 
    available in the buffer pool, then the free space from the buffer pool is allocated to the shared 
    pool.

Answer: A, C

Question 5.
You are performing a block media recovery on the tools01.dbf data file in the SALESdatabase using RMAN. 

Which two statements are correct in this scenario? (Choose two.)

A. You must ensure that the SALES database is mounted or open.
B. You must restore a backup control file to perform a block media recovery.
C. You must take the tools01.dbf data file offline before you start a block media recovery.
D. You must put the database in NOARCHIVELOG mode to perform a block media recovery.
E. You can perform only a complete media recovery of individual blocks, point-in-time recovery of 
    individual data blocks is not supported.

Answer: A, E

Question 6.

Exhibit:
 
You executed the following command to perform a backup of the USERStablespace:
RMAN > BACKUP TABLESPACE USERS;

Which type of backup would this command perform?

A. backup set
B. image copy
C. incremental backup
D. None; the user receives an error indicating that the backup type must be specified.

Answer: A

Question 7.
In your database, online redo log files are multiplexed and one of the members in a group is lost due to media failure?

How would you recover the lost redo log member?

A. import the database from the last export
B. restore all the members in the group from the last backup
C. drop the lost member from the database and then add a new member to the group
D. restore all the database files from the backup and then perform a complete recovery
E. restore all the database files from the backup and then perform an incomplete recovery

Answer: C

Question 8.
You are using Oracle Database 10g. Which statement regarding an incomplete recovery is true?

A. You do not need to restore all the data files.
B. You do not need to open the database with the RESETLOGS operation
C. You do not need to perform a full backup after the RESETLOGS operation.
D. You do not need to recover all the data files to the same system change number (SCN).

Answer: C

Question 9.

Exhibit:
 
View the Exhibit and examine the Resource Manager settings for the groups at different levels.

Which two effects would be the result of this setting? (Choose two.)

A. The members of LOW_GROUP would get more priority than those of OTHER_GROUPS.
B. The members of SYS_GROUP would get most of the CPU allocation at level 1.
C. The members of LOW_GROUP would get most of the CPU allocation because it has CPU 
    allocation at two different levels.
D. The members of LOW_GROUP would get no CPU allocation at level1 if the members of 
    OTHER_GROUPS are using all the CPU at level 2.
E. The members of SYS_GROUP would get no CPU allocation at level 1 if the members of 
    OTHER_GROUPS are using all the CPU at level 2.

Answer: A, B 

Question 10.
The current time zone for one of the user sessions is set to the database local time zone. For one application, the user session requires the time zone to be set to the local operating system time zone without affecting other user sessions.

Which two solutions could the user implement to achieve this objective? (Choose two.)

A. use the ALTER SYSTEM command to change the time zone
B. use the ALTER SESSION command to change the time zone
C. use the ALTER DATABASE command to change the time zone
D. set the value for the operating system variable ORA_SDTZ on the client machine
E. set the value for the operating system variable ORA_SDTZ on the database server machine

Answer: B, D

Question 11.
You work as a database administrator at ITCertKeys .com. Your database is open and running in ARCHIVELOGmode. You take RMANfull backups every Sunday night. On Monday morning, while querying the user1.employeestable, you receive the following error message:
01578: ORACLE data block corrupted (file # 5, block # 51)
ORA-01110: data file 5:
'/u01/app/oracle/oradata/orcl/example01.dbf'

You need to rectify the corruption while ensuring the following: 
The data file should remain online.
The mean time to recover (MTTR) should be minimal.
You are not using a backup control file and all the archived logs are accessible.

Which option would you choose?

A. flash back the corrupted blocks
B. use the DBMS_REPAIR package
C. use the RMAN TSPITR command
D. use the RMAN BLOCKRECOVER command
E. use the RESTORE DATABASE and RECOVER DATABASE commands
F. investigate the time at which the corruption occurred and perform a point-in-time recovery
