Q91. Examine this command:
SQL > exec DBMS_STATS.SET_TABLE_PREFS (‘SH’, ‘CUSTOMERS’, ‘PUBLISH’,
Which three statements are true about the effect of this command?
A. Statistics collection is not done for the CUSTOMERS table when schema stats are gathered.
B. Statistics collection is not done for the CUSTOMERS table when database stats are gathered.
C. Any existing statistics for the CUSTOMERS table are still available to the optimizer at parse time.

Q92. On your Oracle Database, you issue the following commands to create indexes:
SQL > CREATE INDEX oe.ord_customer_ix1 ON oe.orders (customer_id, sales_rep_id) INVISIBLE;
SQL> CREATE BITMAP INDEX oe.ord_customer_ix2 ON oe.orders (customer_id, sales_rep_id);
Which two statements are true?
A. Only the ORD_CUSTOMER_IX1 index created.
B. Both the indexes are updated when a row is inserted, updated, or deleted in the ORDERS table.
C. Both the indexes are created: however, only ORD_CUSTOMERS_IX1 is used by the optimizer for queries on the ORDERS table.
D. The ORD_CUSTOMER_IX1 index is not used by the optimizer even when the OPTIMIZER_USE_INVISIBLE_INDEXES parameters is set to true.
E. Both the indexes are created and used by the optimizer for queries on the ORDERS table.
F. Both the indexes are created: however, only ORD_CUSTOMERS_IX2 is used by the optimizer for queries on the ORDERS table.

Q94. Your database has the SRV1 service configured for an application that runs on middle-tier application server. The application has multiple modules. You enable tracing at the service level by executing the following command:
SQL > exec DBMS_MONITOR.SERV_MOD_ACT_TRACE_ENABLE (‘SRV1’);
The possible outcome and actions to aggregate the trace files are as follows:
1.The command fails because a module name is not specified.
2.A trace file is created for each session that is running the SRV1 service.
3.An aggregated trace file is created for all the sessions that are running the SRV1 service.
4.The trace files may be aggregated by using the trcess utility.
5.The trace files be aggregated by using the tkprof utility.
Identify the correct outcome and the step to aggregate by using tkprof utility?
B. 2 and 4
C. 2 and 5
D. 3 and 4
E. 3 and 5
Q95. Identify two situations in which the alert log file is updated.
A. Running a query on a table returns ORA-600: Internal Error.
B. Inserting a value into a table returns ORA-01722: invalid number.
C. Creating a table returns ORA-00955: name us already in used by an existing objects.
D. Inserting a value into a table returns ORA-00001: unique constraint (SYS.OK_TECHP) violated.
E. Rebuilding an index using ALTER INDEX . . . REBUILD fails with an ORA-01578: ORACLE data block corrupted (file # 14, block # 50) error.
Q96. You created an encrypted tablespace:
You then closed the encryption wallet because you were advised that this is secure.
Later in the day, you attempt to create the EMPLOYEES table in the SECURESPACE
tablespace with the SALT option on the EMPLOYEE column.
Which is true about the result?
A. It creates the table successfully but does not encrypt any inserted data in the EMPNAME column because the wallet must be opened to encrypt columns with SALT.
B. It generates an error when creating the table because the wallet is closed.
C. It creates the table successfully, and encrypts any inserted data in the EMPNAME column because the wallet needs to be open only for tablespace creation.
D. It generates error when creating the table, because the salt option cannot be used with encrypted tablespaces.

C. The granter of system privileges must possess the set container privilege.
D. Common users connected to a PDB can exercise privileges across other PDBs.
E. System privileges with the with grant option container all clause must be granted to a common user before the common user can grant privileges to other users.
Q98. Which three statements are true about Oracle Data Pump export and import operations?
A. You can detach from a data pump export job and reattach later.
B. Data pump uses parallel execution server processes to implement parallel import.
C. Data pump import requires the import file to be in a directory owned by the oracle owner.
D. The master table is the last object to be exported by the data pump.
E. You can detach from a data pump import job and reattach later.
Q99. You executed a DROP USER CASCADE on an Oracle 11g release 1 database and immediately realized that you forgot to copy the OCA. EXAM_RESULTS table to the OCP schema.
The RECYCLE_BIN enabled before the DROP USER was executed and the OCP user has been granted the FLASHBACK ANY TABLE system privilege.
What is the quickest way to recover the contents of the OCA. EXAM_RESULTS table to the OCP schema?
A. Execute FLASHBACK TABLE OCA. EXAM_RESULTS TO BEFORE DROP RENAME TO OCP.EXAM_RESULTS; connected as SYSTEM.
B. Recover the table using traditional Tablespace Point In Time Recovery.
C. Recover the table using Automated Tablespace Point In Time Recovery.
D. Recovery the table using Database Point In Time Recovery.
