S90.03 Exam Syllabus & Core Topics

Use this topic map to guide your study for Arcitura Education S90.03 (SOA Design & Architecture) within the Certified SOA Java Developer path.

• Service Contract Design: Candidates must define clear, reusable service contracts using WSDL and XML Schema, ensuring consistency across distributed systems and minimizing coupling between service consumers and providers.
• Service Composition Patterns: Understand orchestration versus choreography approaches, evaluate trade-offs between centralized and decentralized composition logic, and apply patterns like aggregation and routing to coordinate multiple services.
• Enterprise Service Bus (ESB) Architecture: Design and configure ESB deployments for message routing, transformation, and protocol bridging; assess when an ESB adds value versus introducing unnecessary complexity.
• SOA Governance & Lifecycle: Establish policies for service versioning, registry/repository management, and lifecycle governance; implement controls that balance agility with stability in production environments.
• Security in SOA: Apply authentication, authorization, and encryption strategies across service boundaries; design secure message flows and manage identity propagation in federated SOA landscapes.
• Service Data Management: Handle data consistency, entity resolution, and state management across loosely coupled services; evaluate approaches like eventual consistency and compensating transactions.
• Performance & Scalability: Optimize service communication, implement caching strategies, and design for horizontal scaling; analyze bottlenecks in synchronous and asynchronous call chains.
• Integration Patterns & Protocols: Select appropriate protocols (SOAP, REST, messaging), implement reliable delivery mechanisms, and apply integration patterns (publish-subscribe, request-reply, fire-and-forget).
• Service Testing & Quality Assurance: Design test strategies for distributed services including contract testing, mock services, and end-to-end scenarios; validate non-functional requirements like latency and throughput.
• SOA Migration & Legacy Integration: Plan incremental SOA adoption, wrap legacy systems as services, and manage technical debt; assess risk and ROI for service-oriented transformation initiatives.

Question Formats & What They Test

The S90.03 exam uses multiple question types to assess both conceptual understanding and practical problem-solving in SOA design scenarios.

• Multiple Choice: Test foundational knowledge of SOA principles, terminology, and architectural patterns; questions focus on definitions, feature behavior, and when to apply specific design approaches.
• Scenario-Based Items: Present real-world situations (e.g., "Your organization needs to integrate three legacy systems with a new microservices platform") and require you to evaluate design trade-offs, select appropriate patterns, and justify architectural decisions.
• Design Analysis: Examine incomplete or problematic service architectures and identify gaps, security risks, or performance issues; demonstrate the ability to refactor and improve existing designs.

Questions progress in difficulty and emphasize practical application of SOA concepts to production-like challenges, ensuring candidates can make sound architectural decisions under real constraints.

Preparation Guidance

An effective study plan maps exam topics to structured weekly goals and reinforces learning through practice and cross-topic integration. Dedicate 4-6 weeks to thorough preparation, allocating more time to complex areas like service composition and governance.

• Organize study weeks around topic clusters: start with service contract design and composition patterns (weeks 1-2), move to infrastructure and governance (weeks 3-4), then focus on security, data management, and testing (weeks 5-6).
• Work through practice question sets aligned to each topic; review explanations carefully to understand not just the correct answer but why alternatives fail in specific contexts.
• Connect concepts across the syllabus by studying how security policies affect service contracts, how governance enables composition patterns, and how testing strategies validate performance decisions.
• Take a timed 60-minute mini mock exam 1-2 weeks before your test date to build pacing, identify remaining weak areas, and reduce test-day anxiety.
• In the final week, review high-weight topics (service composition, ESB architecture, SOA governance) and work through scenario-based questions that combine multiple concepts.

Frequently Asked Questions

Which topics carry the most weight on the S90.03 exam?

Service composition patterns, ESB architecture, and SOA governance typically represent 40-50% of exam content. These areas are critical to real-world SOA success and require both theoretical knowledge and practical decision-making. Allocate study time proportionally, but ensure you have solid foundational knowledge across all ten topics to handle scenario questions that combine multiple concepts.

How do service contract design and composition patterns work together in a real project?

Service contracts define the interface and data structure each service exposes; composition patterns determine how multiple services are orchestrated to fulfill business processes. Well-designed contracts make composition simpler and reduce coupling, while poor contracts force composition logic to become complex and brittle. Understanding this relationship helps you recognize when architectural decisions in one area affect another, a key skill tested in scenario-based questions.

What hands-on experience helps most for this exam?

Direct experience designing or implementing WSDL contracts, configuring an ESB platform (such as Apache Camel or MuleSoft), and working with service governance tools provides valuable context. If you lack hands-on experience, focus on understanding the "why" behind design decisions and practice analyzing architecture diagrams and design documents. Lab work on service composition, security policies, and integration patterns will reinforce exam concepts most effectively.

What are common mistakes that cost candidates points?

Misunderstanding the trade-offs between synchronous and asynchronous patterns, overlooking security implications of service design choices, and failing to consider data consistency challenges across service boundaries are frequent pitfalls. Candidates also struggle when they confuse ESB capabilities with service composition logic or neglect governance and lifecycle management in architecture decisions. Carefully read scenario questions to identify all constraints (performance, security, scalability) before selecting an answer.

How should I approach the final week before the exam?

Focus on high-weight topics and scenario-based questions that combine multiple concepts rather than re-reading notes. Take a full-length timed practice test to identify any remaining gaps, then spend 2-3 days drilling those weak areas with targeted Q&A review. In the last 2-3 days, skim your notes on service composition patterns and governance to keep those concepts fresh, and get good sleep the night before the exam to ensure sharp decision-making.
