Your government customer has purchased a full rack of Exadata. The customer has two departments that
would like to share the Exadata Database Machine but the concern is that department A will be able to see
data from department B.
Which architecture would you suggest to solve this deployment issue?

A.
Split the configuration by using Oracle Nimbula’s cloud software so that four database servers and seven
cells can be used by department A and the rest can be used by department B.

B.
Split the configuration and use ASM-Scoped Security so that four database servers and seven cells can be
used by department A and the rest can be used by department B.

C.
Set up instance caging to ensure that department A has access only to four database servers and seven
cells and department B has access to the rest.

D.
Define the split by setting up database services that are specific to department A and department B.
