One advantage of Service Oriented Architecture is that which of the following is true?

• A. Each service is unique and cannot be reused
• B. Services can be used over and over again
• C. It eliminates the need for networks
• D. It guarantees real-time data

Answer: (B)

Reusability of services is a key benefit of Service Oriented Architecture. By designing modular services with well-defined interfaces, you can reuse the same service across multiple applications or workflows, which reduces duplication, speeds development, and promotes consistent behavior across systems. Therefore, the statement that services can be used over and over again is the best fit. The other options don’t hold as advantages of SOA: claiming each service is unique and cannot be reused goes against the very idea of reusability; eliminating the need for networks is incorrect because services must communicate over networks; and guaranteeing real-time data isn’t inherent to SOA—real-time performance depends on design, infrastructure, and SLAs rather than the architecture type alone.
