NEW QUESTION 7
You execute the following piece of code with appropriate privileges:
1Z0-062 dumps exhibit
User SCOTT has been granted the CREATE SESSION privilege and the MGR role.
Which two statements are true when a session logged in as SCOTT queries the SAL column in the view and the table? (Choose two.)

  • A. Data is redacted for the EMP.SAL column only if the SCOTT session does not have the MGR role set.
  • B. Data is redacted for EMP.SAL column only if the SCOTT session has the MGR role set.
  • C. Data is never redacted for the EMP_V.SAL column.
  • D. Data is redacted for the EMP_V.SAL column only if the SCOTT session has the MGR role set.
  • E. Data is redacted for the EMP_V.SAL column only if the SCOTT session does not have the MGR role set.

Answer: AC

Explanation: Note:
* DBMS_REDACT.FULL completely redacts the column data.
* DBMS_REDACT.NONE applies no redaction on the column data. Use this function for development testing purposes. LOB columns are not supported.
* The DBMS_REDACT package provides an interface to Oracle Data Redaction, which enables you to mask (redact) data that is returned from queries issued by low-privileged users or an application.
* If you create a view chain (that is, a view based on another view), then the Data Redaction policy also applies throughout this view chain. The policies remain in effect all of the way up through this view chain, but if another policy is created for one of these views, then for the columns affected in the subsequent views, this new policy takes precedence.

NEW QUESTION 8
Examine the following query output:
1Z0-062 dumps exhibit
You issue the following command to import tables into the hr schema:
$ > impdp hr/hr directory = dumpdir dumpfile = hr_new.dmp schemas=hr TRANSFORM=DISABLE_ARCHIVE_LOGGING: Y

  • C. Only CREATE TABLE and ALTER TABLE statements generated by the import are logged.
  • D. None of the operations against the master table used by Oracle Data Pump to coordinate its activities are logged.

Explanation: Oracle Data Pump disable redo logging when loading data into tables and when creating indexes.
The new TRANSFORM option introduced in data pumps import provides the flexibility to turn off the redo generation for the objects during the course of import. The Master Table is used to track the detailed progress information of a Data Pump job.
The Master Table is created in the schema of the current user running the Pump Dump export or import, and it keeps tracks of lots of detailed information.
