Which statement about co-locating server and client applications on the same device is most accurate?

• A. It is not permitted by any policy
• B. It is allowed but never used
• C. It is required for all hospitals
• D. It is feasible and sometimes implemented to reduce hardware and cost

Answer: (D)

Co-locating server and client applications on the same device is a practical architectural option when the benefits outweigh the risks. It is feasible and sometimes implemented because it can reduce hardware needs, cut costs, and simplify deployment by eliminating extra servers and network infrastructure for certain tasks. This approach can also improve performance in scenarios where local data access is advantageous or network connectivity is limited, such as edge devices or offline operation. However, it carries trade-offs: shared resources can lead to contention, there’s a higher potential for a single point of failure, and security and access controls must be carefully managed to protect PHI. In healthcare environments, you’d apply robust segmentation, encryption, and strict access controls regardless of whether components are co-located.
