Which two of the following features or options can be used to implement security based on data
values in individual rows?
A.
Advanced Security
B.
Oracle Database Vault
C.
Oracle Audit Vault
D.
Oracle Label Security
E.
Oracle Data Masking Pack
F.
Virtual Private Database
Explanation:
Both Oracle Virtual Private Database (VPD) and Oracle Label Security (OLS) enable you to restrict the
data that different users can see in database tables. But when should you use Virtual Private
Database and when should you use Oracle Label Security? Virtual Private Database is effective when
there is existing data you can use to determine the access requirements. For example, you can
configure a sales representative to see only the rows and columns in a customer order entry table
for orders he or she handles. Oracle Label Security is useful if you have no natural data (such as user
accounts or employee IDs) that can be used to indicate a table’s access requirements. To determine
this type of user access, you assign different levels of sensitivity to the table rows.
