departmental databases, which are synchronized weekly. What would be the BEST recommendation?

A.
increase the frequency for data replication between the different department systems to ensure timely
updates.

B.
Centralize all request processing in one department to avoid parallel processing of the same request.

C.
Change the application architecture so that common data are held in just one shared database for all
departments.

D.
implement reconciliation controls to detect duplicates before orders are processed in the systems.

Explanation:
Keeping the data in one place is the best way to ensure that data are stored without redundancy and that all
users have the same data on their systems. Although increasing the frequency may help to minimize the
problem, the risk of duplication cannot be eliminated completely because parallel data entry is still possible.
Business requirements will most likely dictate where data processing activities are performed. Changing the
business structure to solve an IT problem is not practical or politically feasible. Detective controls do not solve
the problem of duplicate processing, and would require that an additional process be implemented to handlethe discovered duplicates.
