What could be the reason for it? (Choose all that apply.)
A. The OPTIMIZER_INDEX_COST_ADJ initialization parameter has a low value.
B. The DB_FILE_MULTIBLOCK_READ_COUNT initialization parameter has a low value.

The statistics for the CUSTOMERS table have been updated recently by using the following command:
SQL> EXEC DBMS_STATS.GATHER_TABLE_STATS('SH','CUSTOMERS',method_opt=>'FOR ALL
INDEXED COLUMNS SIZE AUTO');
View Exhibit2 to examine a query plan. Even though the index is present on the COUNTRY_ID and
CUST_GENDER columns, the query uses a full table scan. What could be the reason?
A. because the histogram statistics for the COUNTRY_ID column are not updated
B. because the DB_FILE_MULTIBLOCK_READ_COUNT initialization parameter is set to a high value
C. because the optimizer calculates the cost of accessing blocks by using a full table scan to be less as
compared to index scans, even though indexes are available
D. because indexes on CUST_GENDER and COUNTRY_ID columns are of different types, the index on
the CUST_GENDER column is bitmap index, and on COUNTRY_ID columns is btree index.

database.
On further investigation, you find that at the end of each day the contents of the SALES_RECORDS table
are transferred to the SALES table and deleted from the SALES_RECORDS table. The deleted
operations cause the table to be sparsely populated.
You decided to use the ALTER TABLE...SHRINK SPACE COMPACT command to shrink the table.
Why would you choose this method? (Choose all that apply.)
A. because it can be used during peak hours
B. because it avoids unnecessary cursor invalidation
C. because it adjusts the high-water mark (HWM) immediately
D. because you have long-running queries that might span the shrink operation
E. because it does not allow any data manipulation language (DML) operations, thereby making the
shrink
operation faster

optimizer_index_caching integer 0
optimizer_index_cost_adj integer 100
optimizer_mode string ALL_ROWS

You notice that the one of the queries is using a full table scan (view Exhibit1) instead of index unique
scan (view Exhibit2). The index is present on the column that is accessed in the WHERE clause of the
query. The cost for a full table scan is more than that for an index unique scan.
Why would the optimizer choose full table scan over index unique scan? (Choose all that apply.)
A. The OPTIMIZER_INDEX_COST_ADJ initialization parameter is set to a low value.
B. The OPTIMIZER_INDEX_COST_ADJ initialization parameter is set to a high value.
C. The DB_FILE_MULTIBLOCK_READ_COUNT initialization parameter is set to a low value.

together in the WHERE clause of the queries. The CUSTOMERS table is a big table with 20 GB of data.
You notice that the selectivity for these three columns varies from the selectivity that the optimizer
calculates.
What would you recommend to influence the selectivity calculated by the optimizer?
A. creating function-based indexes by concatenating all the columns
B. updating histogram statistics for these columns by using the DBMS_STATS.GATHER_TABLE_STATS
procedure
C. using the DBMS_STATS.CREATE_EXTENDED_STATS function to create a virtual column and create

INDEXED COLUMNS SIZE AUTO');
View Exhibit2 to examine a query plan. Even though the index is present on the COUNTRY_ID and
CUST_GENDER columns, the query uses a full table scan. What could be the reason?
A. because the histogram statistics for the COUNTRY_ID column are not updated
B. because the DB_FILE_MULTIBLOCK_READ_COUNT initialization parameter is set to a high value
C. because the optimizer calculates the cost of accessing blocks by using a full table scan to be less as
compared to index scans, even though indexes are available
D. because indexes on CUST_GENDER and COUNTRY_ID columns are of different types, the index on
the CUST_GENDER column is bitmap index, and on COUNTRY_ID columns is btree index.

database.
On further investigation, you find that at the end of each day the contents of the SALES_RECORDS table
are transferred to the SALES table and deleted from the SALES_RECORDS table. The deleted
operations cause the table to be sparsely populated.
You decided to use the ALTER TABLE...SHRINK SPACE COMPACT command to shrink the table.
Why would you choose this method? (Choose all that apply.)
A. because it can be used during peak hours
B. because it avoids unnecessary cursor invalidation
C. because it adjusts the high-water mark (HWM) immediately
D. because you have long-running queries that might span the shrink operation
E. because it does not allow any data manipulation language (DML) operations, thereby making the

NO.10 You are about to build a new Oracle Clusterware-based cluster and you want to make the
installation process as smooth as possible. You decide to use the Cluster Verification Utility
(CLUVFY) to check whether or not your system administrator has set up the hardware and system
software correctly. Which two statements about CLUVFY are true? (Choose two.)
A.You can run CLUVFY only from a privileged operating system account.
B.You can run CLUVFY directly from the Oracle Clusterware distribution media.
C.CLUVFY cannot be used until the Oracle Clusterware is installed successfully.
D.After the Oracle Clusterware installation, you can run CLUVFY from the Oracle Home that holds the
CRS binaries.
E.You have to install CLUVFY on all cluster nodes in order to use CLUVFY on other nodes than the one
from which you perform the installation.
F.To use CLUVFY during the Oracle Clusterware installation, you have to download CLUVFY from the
Oracle Technology Network (OTN) Web site and install it before you can use it.

NO.11 View the Exhibit, which displays the cluster database performance page after the same
workload has been executed three times on your cluster without varying any non-Oracle
workloads on the cluster. What are the two ways by which you can tell that the corresponding
application was better tuned during the second and third execution? (Choose two.)
A.There is less paging each time.
B.The run queue length is going down each time.
C.It takes less time to execute the workload each time.
D.The number of transactions per second is getting higher each time.
E.The database throughput graphic is below the red dashed line during the last execution.

NO.12 You are working as a DBA in a RAC environment that is available for testing. The RAC
environment has all the database files stored in the OCFS file system. You plan to install ASM and
move all the database files to ASM to achieve better performance. During the installation, you
selected redundancy level as normal for the disk group being added. What is the reason for
selecting this redundancy level?
A.You want to use hardware mirroring.
B.You do not want to have any mirroring in the disk group.
C.You have two failure groups defined, so you want to use two-way mirroring.
D.You have three failure groups defined, so you want to use three-way mirroring.

NO.13 You have a well-tuned, non-RAC single instance Oracle database with several services, all of
which perform perfectly. You plan to migrate the database to RAC in the next two weeks and all file
systems would be shared using Oracle Cluster File System. After the migration, you want to
perform a test to monitor RAC-specific tuning issues that would not have occurred on a non-RAC
database. Which six areas would you monitor to determine whether there are RAC-specific
performance problems after migration? (Choose six.)
A.Interconnect latency
B.Instance recovery time
C.Services with applications that use external tables
D.Services with applications that truncate large tables
E.Services with applications using local context variables
F.Services with query-intensive applications relying on full table scans
G.Services with insert-intensive applications that use Oracle sequences for index keys
H.Services with applications that have occasional queries, using index access on modestly sized tables
I.Services with insert-intensive applications that generate their own keys without Oracle sequences
