The S90.03 exam (SOA Design & Architecture) is designed for Java developers pursuing the Certified SOA Java Developer credential through Arcitura Education. This exam validates your ability to design and architect service-oriented solutions, understand core SOA principles, and apply them in real-world scenarios. Whether you're preparing for the first time or refining your knowledge, this page provides a clear roadmap of exam topics, question formats, and practical preparation strategies to help you succeed.
Use this topic map to guide your study for Arcitura Education S90.03 (SOA Design & Architecture) within the Certified SOA Java Developer path.
The S90.03 exam uses a variety of question formats to assess both conceptual knowledge and practical decision-making skills in SOA design scenarios.
Questions progress in difficulty and emphasize practical reasoning, you'll need to justify why one approach is better than another, not just recall definitions.
Effective preparation for S90.03 requires systematic study of each topic area combined with regular practice and self-assessment. A structured approach helps you identify weak areas early and build confidence in applying SOA concepts to unfamiliar scenarios.

Service design, composition patterns, and governance typically account for a significant portion of exam questions. However, all ten topics are important, the exam tests breadth of knowledge across the full SOA landscape. Focus on understanding how these high-weight areas connect to other concepts rather than neglecting less-emphasized topics entirely.
Service design decisions (like contract structure and versioning) directly impact how services can be composed and governed. A well-designed contract makes composition simpler and governance easier to enforce. In practice, you'll find that poor design choices early on create governance and integration headaches later, so understanding these connections is critical for both the exam and real work.
Practical experience designing service contracts, building a simple service composition, and working with a service registry is valuable. If you haven't done this, focus exam prep on scenario-based questions that simulate these tasks. Understanding how Java frameworks implement SOA concepts, such as SOAP web services or REST APIs, will also strengthen your ability to apply theory to practice.
Many candidates confuse orchestration with choreography or misapply patterns to inappropriate scenarios. Others overlook the importance of non-functional requirements like security and performance in design decisions. A frequent error is choosing a technically correct answer that ignores business context or governance constraints, always read scenario questions carefully for all constraints.
Review your practice test results and focus on topics where you scored below 80 percent. Redo scenario-based questions that challenged you, paying attention to the reasoning behind each answer. Take one full-length timed practice test to build confidence and ensure your pacing allows time for all questions. Avoid cramming new material; instead, reinforce what you've already studied.
I was discussing my new service with a client who told me that my technical service contract revealed too much information about the underlying service design. For example, based only on the names of my service capabilities, my client could determine that the service was using an Oracle database. What service-orientation principle should I apply to address this problem? Select the correct answer.
The following statement describes the relationship between the Service Reusability principle and which other design principle? "Because of the potentially high performance and concurrent usage demands of reusable services, the extent of control they can exercise over their underlying environment is an important design consideration in guaranteeing an acceptable level of predictable runtime behavior." Select the correct answer.
Which are the three design principles that often act as regulators to ensure that the remaining five principles are properly applied: SELECT ALL THAT APPLY
The "contract first" approach to building services helps realize contract-to-logic coupling. Select the correct answer.
I have a service composition with three services. Service A retrieves a list of country codes from a database and keeps this data in memory while interacting with Service B and Service C. However, because Service A is concurrently invoked many times, and because each instance of Service A loads its own copy of the country code data into memory, the demands on the overall infrastructure become too high and performance and reliability are negatively affected. Which service-orientation principle can be applied to help solve this problem? Select the correct answer.
