Which of the following is NOT a characteristic of a distributed data processing (DDP) approach?

A.
Consists of multiple processing locations that can provide alternatives for computing in the event
of a site becoming inoperative.

B.
Data stored at multiple, geographically separate locations is easily available to the user.

C.
Distances from user to processing resource are transparent to the user.

D.
Security is enhanced because of networked systems.

Explanation:
Security is more of a concern in distributed systems since there are vulnerabilities associated with
the network and the many locations from which unauthorized access to the computing resources
can occur. The other answers are characteristics of a DDP architecture.
