• D、 The user， BLAKE， cannot start a transaction that uses any DML operations until you increase the value of the undo pool resource plan directive.
• E、 The user BLAKE can start a transaction that uses any DML operations after the batch operation started by the user， SCOTT， terminates with an error.

第5题：

You want to create a consumer group， GROUP1， and you execute the following command in the command-line interface：  SQL> EXEC DBMS_RESOURCE_MANAGER.CREATE_CONSUMER_GROUP （CONSUMER_GROUP =>’group1’， COMMENT => ’New Group’）；  This command errorsout displaying the following message：  ERROR at line 1：  ORA-01031： insufficient privileges  ORA-06512： at "SYS.DBMS_RMIN"， line 115  ORA-06512： at SYS.DBMS_RESOURCE_MANAGER"， line 108 ORA-06512： at line 1  What action would you take to overcome this error？（）

• B、 grant SYSOPER to the user
• C、 grant the RESOURCE role to the user
• D、 use the GRANT command to grant the ADMINISTER_RESOURCE_MANAGER privilege to the use

第6题：

The HR user creates a view with this command：  SQL> CREATE VIEW emp_v AS SELECT * FROM scott.emp；  Now HR wants to grant the SELECT privilege on the EMP_V view to the JIM user.  Which statement is true in this scenario？（）

• A、HR can grant the privilege to JIM but without GRANT OPTION.
• B、HR can grant the privilege to JIM because HR is the owner of the view.
• C、SCOTT has to grant the SELECT privilege on the EMP table to JIM before this operation.
• D、HR needs the SELECT privilege on the EMP table with GRANT OPTION from SCOTT for this operation.

第7题：

Manually， you set the consumer group of all of the newly created users to MYDB_GRP. You want the users to be able to change their consumer groups as per the application requirement. What was the first step that was needed in the process to achieve this objective？（）

第9题：

You issue the following code：    EXEC DBMS_RESOURCE_MANAGER_PRIVS.GRANT_SWITCH_CONSUMER_GROUP        （’SCOTT’ ’GRP1’， TRUE）；   What will be the result of executing the above code？（）  

• A、 The switch privilege will be granted to the user， Scott， for changing the consumer group to GRP1.
• B、 The switch privilege will be granted to the user， Scott， for changing the consumer group from GRP1 to any other group.
• C、 The code will not execute successfully because there is no GRANT_SWITCH_CONSUMER_GROUP procedure in the DBMS_RESOURCE_MANAGER_PRIVS package.
• D、The code will execute successfully but no privilege will be granted to the user， Scott.

第10题：

The user HR owns the EMP table. The user HR grants privileges to the user SCOTT by using this command：  SQL> GRANT SELECT，INSERT，UPDATE ON emp TO scott WITH GRANT OPTION； The user SCOTT executes this command to grant privileges to the user JIM： SQL> GRANT SELECT，INSERT，UPDATE ON hr.emp TO jim；  Now， the user HR decides to revoke privileges from JIM using this command： SQL> REVOKE SELECT，INSERT，UPDATE ON emp FROM jim； Which statement is true after HR issues the REVOKE command（）

• A、The command fails because SCOTT still has privileges.
• B、The command succeeds and privileges are revoked from JIM.
• C、The command fails because HR cannot revoke the privileges from JIM.
• D、The command succeeds and only HR has the privilege to perform the SELECT， INSERT， and UPDATEoperations on the EMP table.
