S90.05 is Arcitura Education's SOA Technology Lab exam, part of the SOA Certified Professional (SOACP) program and associated with the Certified SOA .NET Developer credential. It is a hands-on, scenario-based exam that tests how well you apply core service technologies: XML and XML Schema, WSDL, SOAP, WS-Policy, WS-BPEL, UDDI, and REST with HTTP methods and uniform contracts. The exam is delivered through Pearson VUE test centres and OnVUE online proctoring, and vouchers are ordered from Arcitura. TroyTec offers 40 S90.05 practice questions in PDF and Online Test Engine formats and AI feature.
S90.05 is the practical technology exam in Arcitura's SOA Certified Professional program and a key step toward the Certified SOA .NET Developer credential. It doesn't ask you to define service-orientation. It puts you in developer-level scenarios where you work with the standards that service-oriented solutions are built on. You might need to write a schema that validates a product record, define WSDL operations with the right request and response messages, structure a SOAP message, or decide how a REST service should use HTTP methods under a uniform contract.
Most S90.05 scenarios test how the core standards fit together. You need to know how SOAP messages rely on WSDL and XML Schema, how WSDL definitions attach WS-Policy, and how a WS-BPEL process builds on WSDL contracts. Candidates who understand those relationships, rather than memorizing each standard separately, handle the lab-style questions with far more confidence.
.NET and Java developers building Web services or REST APIs.
Integration specialists and middleware engineers who configure service contracts and messaging.
QA and test engineers who validate service behaviour.
Candidates pursuing the Certified SOA .NET Developer credential.
Professionals preparing for Arcitura's architecture exams, such as S90.08 Advanced SOA Design & Architecture and S90.08B SOA Design & Architecture Lab.
Build your XML foundation. Get comfortable with XML syntax, namespaces, and XML Schema complex and simple types. Every other standard on the exam depends on them.
Master service contracts. Study WSDL definition structure, operations and messages, then learn how WS-Policy attaches to WSDL.
Connect messaging and composition. Practice SOAP message structure, headers and faults, then see how WS-BPEL processes invoke WSDL-defined services.
Practice scenarios under time pressure. Use TroyTec's Online Test Engine to work through requirement-plus-schema scenarios, and review every explanation until you can justify each answer.

S90.05 is Arcitura Education's SOA Technology Lab exam in the SOA Certified Professional program. It tests how well you apply XML, XML Schema, WSDL, SOAP, WS-Policy, WS-BPEL and REST in practical scenarios.
S90.05 is associated with Arcitura's Certified SOA .NET Developer credential in the SOACP program. Contact Arcitura to confirm current track requirements.
The questions are scenario-based. You typically review a service requirement along with a schema, WSDL definition or message sample, then choose the correct implementation.
Focus on how the standards relate to each other: SOAP to WSDL and XML Schema, WSDL to WS-Policy, and WS-BPEL to WSDL. Also cover XML Schema types, HTTP methods, uniform contracts and UDDI basics.
It suits developers, integration specialists, middleware engineers and test engineers who build or validate Web services and REST services, especially those pursuing the Certified SOA .NET Developer credential.
S90.05 tests hands-on work with service technologies. S90.08B tests applying SOA design and architecture to case studies involving services and microservices.
