Question 53

You execute the following commands to audit database activities:
SQL > ALTER SYSTEM SET AUDIT_TRIAL=DB, EXTENDED SCOPE=SPFILE;
SQL > AUDIT SELECT TABLE, INSERT TABLE, DELETE TABLE BY JOHN By SESSION WHENEVER SUCCESSFUL;
Which statement is true about the audit record that generated when auditing after instance restarts?

A. One audit record is created for every successful execution of a SELECT, INSERT OR DELETE command on a table, and contains the SQL text for the SQL Statements.
B. One audit record is created for every successful execution of a SELECT, INSERT OR DELETE command, and contains the execution plan for the SQL statements.
C. One audit record is created for the whole session if john successfully executes a SELECT, INSERT, or DELETE command, and contains the execution plan for the SQL statements.
D. One audit record is created for the whole session if JOHN successfully executes a select command, and contains the SQL text and bind variables used.
E. One audit record is created for the whole session if john successfully executes a SELECT, INSERT, or DELETE command on a table, and contains the execution plan, SQL text, and bind variables used.

Correct Answer:A
Note:
* BY SESSION
In earlier releases, BY SESSION caused the database to write a single record for all SQL statements or operations of the same type executed on the same schema objects in the same session. Beginning with this release (11g) of Oracle Database, both BY SESSION and BY ACCESS cause Oracle Database to write one audit record for each audited statement and operation.
* BY ACCESS
Specify BY ACCESS if you want Oracle Database to write one record for each audited statement and operation. Note:
If you specify either a SQL statement shortcut or a system privilege that audits a data definition language (DDL) statement, then the database always audits by access. In all other cases, the database honors the BY SESSION or BY ACCESS specification.
* For each audited operation, Oracle Database produces an audit record containing this information:
/ The user performing the operation
/ The type of operation
/ The object involved in the operation
/ The date and time of the operation References:

Question 54

Examine the following commands for redefining a table with Virtual Private Database (VPD) policies:
1Z0-062 dumps exhibit
Which two statements are true about redefining the table? (Choose two.)

A. All the triggers for the table are disabled without changing any of the column names or column types in the table.
B. The primary key constraint on the EMPLOYEES table is disabled during redefinition.
C. VPD policies are copied from the original table to the new table during online redefinition.
D. You must copy the VPD policies manually from the original table to the new table during online redefinition.

Correct Answer:BC
C (not D): CONS_VPD_AUTO
Used to indicate to copy VPD policies automatically
* DBMS_RLS.ADD_POLICY
/ The DBMS_RLS package contains the fine-grained access control administrative interface, which is used to implement Virtual Private Database (VPD).DBMS_RLS is available with the Enterprise Edition only.
Note:
* CONS_USE_PK and CONS_USE_ROWID are constants used as input to the "options_flag" parameter in both the START_REDEF_TABLE Procedure and CAN_REDEF_TABLE Procedure. CONS_USE_ROWID is used to indicate that the redefinition should be done using rowids while CONS_USE_PK implies that the redefinition should be done using primary keys or pseudo-primary keys (which are unique keys with all component columns having NOT NULL constraints).
* DBMS_REDEFINITION.START_REDEF_TABLE
To achieve online redefinition, incrementally maintainable local materialized views are used. These logs keep track of the changes to the master tables and are used by the materialized views during refresh synchronization.
* START_REDEF_TABLE Procedure
Prior to calling this procedure, you must manually create an empty interim table (in the same schema as the table to be redefined) with the desired attributes of the post-redefinition table, and then call this procedure to initiate the redefinition.

Question 55

Examine the following steps:
ADBA grants the CREATE TABLE system privilege with ADMIN OPTION to the user SIDNEY. SIDNEY grants the CREATE TABLE system privilege to the HR user.
Which statement is true?

A. SIDNEY can revoke the CREATE TABLE system privilege only from HR, to whom he granted it.
B. HR can grant the CREATE TABLE system privilege to other users.
C. Neither SIDNEY nor HR can create new tables if the DBA revokes the CREATE TABLE privilege from SIDNEY.
D. HR still retains the CREATE TABLE system privilege if the DBA revokes the CREATE TABLE privilege from SIDNEY.
