关于oracle认证考试，最近有人向我打听有没有什么题库可以拿来参考，呵呵。那我就晒一下最近从网上拉的战果吧！
虽然只是一些题目，但是找到它已经算是很不容易了，因为像有些网站上的题库不是最新的也不是最全的。
下面是我从一家题库网上拉下来的，据说是最近新的也是最全的，需要的朋友你可以过来看看。已经考过的朋友也可以评评理到底是不是这样一种情况呢？
1.Identify the two direct sources from where SQL plans can be loaded into the SQL plan baselines.
(Choose two.)
A.Cursor cache
B.Stored outline
C.SQL Tuning Set
D.Automatic Workload Repository (AWR) snapshots
Correct:A C
2.Which two statements about workload capture and replay operations are true? (Choose two.)
A.The clients must be created manually on the test machines to perform more realistic testing.
B.Restart the database in RESTRICTED mode before beginning workload replay to enable a clean state
for workload replay.
C.Restart the database in RESTRICTED mode before beginning workload capture to enable a clean state
for capturing the workload.
D.The application state of the capture system must be identical to the application state of the replay
system when the workload replay begins.
Correct:C D
3.View the Exhibit exhibit1 to examine the series of SQL commands. View the Exhibit exhibit2 to
examine the plans available in the SQL plan baseline. The baseline in the first row of the Exhibit is
created when OPTIMIZER_MODE was set to FIRST_ROWS. Which statement is true if the SQL
query in exhibit1 is executed again when the value of OPTIMIZER_MODE is set to FIRST_ROWS?
A.The optimizer uses a new plan because none of the plans in the exhibit2 are fixed plans.
B.The optimizer uses the plan in the second row of the exhibit2 because it is an accepted plan.
C.The optimizer uses the plan in the first row of the exhibit2 because it is the latest generated plan.
D.The optimizer uses the plan in the first row of the exhibit2 because OPTIMIZER_MODE was set to
FIRST_ROW during its creation.
Correct:B
4.Which statement describes the effect of table redefinition on the triggers attached to the table?
A.All triggers on the table remain valid.
B.All triggers on the table are invalidated and are automatically revalidated with the next DML execution
on the table.
C.All triggers on the table are invalidated and must be manually recompiled before the next DML
execution on the table.
D.Only triggers that are affected by the changes to the structure of the table are invalidated and
automatically revalidated with the next DML execution on the table.
Correct:B
5.USER_DATA is a nonencrypted tablespace that contains a set of tables with data. You want to
convert all existing data in the USER_DATA tablespace and the new data into the encrypted format.
Which methods would you use to achieve this? (Choose all that apply.)
A.Use Data Pump to transfer the existing data to a new encrypted tablespace.
B.Use ALTER TABLE..MOVE to transfer the existing data to a new encrypted tablespace.
C.Use CREATE TABLE AS SELECT to transfer the existing data to a new encrypted tablespace.
D.Enable row movement for each table to be encrypted and then use ALTER TABLESPACE to encrypt
the tablespace.
E.Encrypt the USER_DATA tablespace using the ALTER TABLESPACE statement so that all the data in
the tablespace is automatically encrypted.
Correct:A B C
