The S90.05 exam, part of the Certified SOA NET Developer certification path, validates your ability to design, implement, and manage service-oriented architecture solutions using .NET technologies. This exam is designed for developers and architects who have hands-on experience with SOA principles and need to demonstrate both theoretical knowledge and practical problem-solving skills. Arcitura Education's SOA Technology Lab provides the foundation for this exam, offering real-world scenarios and technical depth. This page guides you through the syllabus, question formats, and effective preparation strategies to help you succeed.
Use this topic map to guide your study for Arcitura Education S90.05 (SOA Technology Lab) within the Certified SOA NET Developer path.
The S90.05 exam combines knowledge-based questions with scenario-driven items that assess your ability to make sound architectural decisions. Questions progress in difficulty and reflect real-world SOA challenges you will encounter in production environments.
Effective preparation maps the ten exam topics to a structured study plan, with regular practice and cross-topic review. Dedicate time each week to one or two topics, then revisit them as you progress to build connections across the syllabus. This layered approach reduces last-minute cramming and builds confidence in your decision-making.

Service contract design, .NET service implementation, and service composition typically represent 40-50% of the exam. Security and monitoring are also heavily tested because they directly impact production reliability. Focus your study time on these areas first, then deepen your knowledge of versioning, transaction management, and performance optimization.
In practice, you start with SOA fundamentals and design a clear service contract; then you implement the service using .NET, apply security policies, and configure monitoring. As the system grows, you compose services into workflows, manage versions, handle distributed transactions, and optimize performance. The exam tests your ability to see these connections and make decisions that affect multiple objectives at once.
The exam assumes you have built at least one or two services and configured bindings, endpoints, and security settings. You don't need to be an expert, but you should understand how to create a basic WCF service, host it, and troubleshoot common configuration errors. If you lack hands-on experience, set up a simple service lab before taking the exam to build confidence.
Candidates often overlook versioning implications when designing service contracts, choose overly complex solutions when simpler patterns fit better, and misunderstand the trade-offs between synchronous and asynchronous messaging. Another frequent error is selecting a security approach without considering its impact on performance or monitoring. Read scenario items carefully, consider constraints, and eliminate options that solve only part of the problem.
Focus on high-weight topics and scenario items that combine multiple objectives. Review your practice test results to identify patterns in your mistakes, whether you struggle with security decisions, composition patterns, or performance analysis, and drill those areas. Do a final timed practice test three days before the exam, then spend your last days reviewing explanations and building mental models of how decisions cascade across the architecture.
You currently have a Catalog service that currently imports an XML schema that is based on PROD-XML, an industry standard vocabulary for representing product catalog information. Specifically, the Catalog service WSDL definition contains "message" elements that reference the "productDefinition" element that is defined in the "prod1Q.xsd" schema. The current WSDL definition is as follows:
A new version of the PROD-XML vocabulary is released and you are required to upgrade from the "prod10.xsd" schema to the new version, "prod20.xsd" schema. Although the new version still defines an element named "productDefinition", the target namespace of the schema has changed from "http://www.prod-consortium.org" to "http://www.prod-consortium.0rg/2.O". You now need to update the WSDL definition to reflect this change. Which of the following is correct?
You are building the Quote Request service that allows other services to request the current value of a stock. You have developed the following WSDL definition for this service:
The "message" element named "QuoteRequestMessage" represents the request message sent to the service and the "message" element named "QuoteResponseMessage" represents the response message that the service responds with. Your next task is to define the concrete description for this WSDL definition and you start with the "binding" element. Which of the following represents the correct "binding" element for this WSDL definition?
You are working with an Authentication service that submits user credentials for authentication purposes. Atypical XML document passed to the service looks like this:
You are contacted by the IT department manager and told that from now on, all XML documents that are passed to and from services must have a namespace in order to more easily identify their related XML schema definitions. You revise the above sample document by adding a namespace declaration, as well as prefixes to the "user" element, as shown here:
Assuming the "date" element is of type date, the "login" element is of type string, and the "password" element is of type hexBinary, which of the following XML schemas will correctly validate the revised sample?
You have written the following WSDL definition to describe the Payroll service, which provides a "PayrollNotification" operation that sends out employee payroll information:
Subsequent to a review by the enterprise architecture team, you are notified that although this WSDL definition is technically correct, it is not in compliance with current internal design standards. Specifically, it is a current convention for the WSDL namespace to be the default namespace, rather than using the "wsdl" prefix. Furthermore, another design standard dictates that the "Ins" always be used to represent the target namespace. Which of the following WSDL definitions have been correctly revised to comply with the design standards?
Your company is developing an Articles service that will encapsulate a legacy content management system. The existing content management system uses a proprietary XML vocabulary (called ArticleML). Each article record in the system is represented by an "article" element as shown here:
The new Articles service contract is able to continue using this XML document structure for article data it will exchange via request and response messages. However, the existing content management system was not designed to work with XML Schema. The proprietary article records were stored as XML documents but never validated using XML Schema. You are tasked with the responsibility of defining a WSDL definition with an embedded XML schema for the new Articles service. As a start, you are asked to create preliminary versions of the WSDL definition and XML schema so that they only define the first "message" element for the request message that submits an article record to the service, as per the example above. Which of the following accomplishes this?
