The Certified SOA NET Developer S90.05 exam, delivered through SOA Technology Lab by Arcitura Education, validates your ability to design, implement, and manage service-oriented architecture solutions using .NET technologies. This exam is designed for developers and architects who need to demonstrate practical expertise in SOA principles, messaging patterns, and cloud-based integration. This page guides you through the exam structure, core topics, 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 and scenario-driven questions to assess both conceptual understanding and practical decision-making. Questions progress in difficulty and reflect real-world SOA implementation challenges.
Efficient preparation requires mapping each exam objective to focused study weeks and hands-on practice. Start by reviewing the ten core topics in order, then reinforce learning through scenario-based questions and mini labs. Allocate extra time to areas where you have less production experience.

Service contract design, message exchange patterns, and service composition typically account for a larger share of exam questions because they form the foundation of SOA implementations. Security, monitoring, and deployment are also heavily tested. Focus your study time proportionally on these areas, but ensure you have working knowledge of all ten objectives.
Service contracts define the data structure and format that services exchange; data transformation logic then converts data between different contract formats when services from different teams or legacy systems communicate. Understanding both ensures you can design contracts that minimize transformation overhead and build transformation rules that preserve data integrity across service boundaries.
Practical experience with at least three to four core SOA scenarios (such as designing a contract, implementing a message queue, or configuring security) significantly improves your ability to answer scenario-based questions correctly. If you lack production experience, prioritize labs that cover contract design, messaging patterns, and security configuration.
Candidates often confuse message patterns or choose patterns that don't match the performance and reliability requirements described in scenarios. Others overlook security implications when designing service interactions or fail to consider deployment and versioning constraints. Read scenario questions carefully, identify the key constraint (latency, security, scalability), and verify your answer addresses it.
Review weak topics identified in your practice tests rather than re-reading all material. Take one more full-length practice test to verify pacing and confidence. Spend the last two days reviewing scenario-based questions and their explanations to reinforce decision-making logic. On exam day, read each question twice before answering to catch nuances you might otherwise miss.
You are asked to build a newTimesheet service that needs to provide centralized access to timesheet-related data access functions. Because the service delivery project team follows a "contract-first" approach when building any service, you and your group of developers are asked to create a WSDL definition that will need to import an existing "Employee.xsd" schem
a. Furthermore, in order to comply with established design standards and conventions, you are given the following instructions as to how the WSDL definition must be designed:
* It must contain a "message" element for the request message with the name "getWeeklyHoursRequestMessage". The "message" element must contain a "part" element that references the "EmployeeHoursRequestType" element defined in the imported XML schema.
* It must contain a "message" element for the response message with the name "getWeeklyHoursResponseMessage".The "message" element must contain a "part" element that references the "EmployeeHoursResponseType" element defined in the imported XML schema.
* It must contain a "portType" element called Timesheetlnterface" that contains an "operation" element called "GetWeeklyHoursLimit", an "input" element referencing the request message and an "output" element referencing the response message.Three of your junior developers take on this assignment. At the end of the day, each developer presents you with a different WSDL definition. Which of the following is a correctly designed WSDL definition that also complies with the above instructions?
You have created the following XML Schema definition for a new Invoice Reporting service:
The Invoice Reporting service needs to represent invoice data in a unique format. Therefore, this schema will only be used by the WSDL definition for the Invoice Reporting service. As a result, you decide to embed the schema inside the WSDL definition. Which of the following shows a valid way to accomplish this?
You are in the process of designing a service that manages content in a database of medical images. The service is able to add, update and delete images in the database. Each of these three functions requires a separate message exchange with the service. Therefore, the XML schema for this service provides an "addimage" element, an "updateimage" element and a "deleteimage" elements for the request messages, and separate "addlmageResponse," "updateimageResponse" and "deletelmageResponse" elements for the response messages.
Which of the following describes the minimum number of WSDL "message", "operation", "portType", "binding", and "service" elements that the WSDL definition must have for this service?
A partner organization has given you samples of XML documents retrieved from their product information database. The three samples they have sent you are:
Because they are an important partner, you have agreed to write a service to accept XML documents in their format. However, they did not send you a schema, so you are tasked with defining a schema that will correctly validate their documents. Which of the following XML schemas will successfully validate each of the above XML document fragments?
You have developed the following WSDL definition for the Article Notification service that needs to be able to notify employees when a new article has been posted to the company's internal intranet Web site:
The service has an "ArticleNotification" operation that receives a request message containing the article information. The receipt of this request message triggers the issuance of a notification to employees. This operation does not issue a response message. Your next task is to define the concrete description for this WSDL definition. You have already completed the "binding" element and you now need to add the "service" element. Which of the following represents the correct "service" element for this WSDL definition?
