What is a task that service-oriented architecture (SOA) reduces or eliminates?

• A. File integration between systems
• B. Data entry
• C. Payroll processing
• D. Employee scheduling

Answer: (A)

SOA focuses on decoupling systems and exposing functionality as reusable services with standard interfaces. Because communication happens through service calls and messages rather than exchanging files directly, organizations don’t need to build and maintain file-based integrations between each system. Data moves through structured messages via an integration backbone like an enterprise service bus or API gateway, which simplifies maintenance and boosts agility. This is why file integration between systems is reduced or eliminated. The other options describe business processes or operations that SOA can automate or support, but they aren’t about how systems exchange data.
