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.
