Solution Architects and System Integrators must demonstrate expertise in deploying and managing IBM WebSphere DataPower SOA Appliances running firmware version 5.0. Candidates implement security policies using WS-Security, AAA frameworks, and SSL profiles while configuring XML, JSON, and SOAP message transformation via XSLT and GatewayScript. The assessment covers service-oriented architecture integration, including Web Services Proxy and Multi-Protocol Gateway configuration, alongside robust troubleshooting, logging, and monitoring techniques. Practitioners execute administrative tasks such as firmware upgrades, secure backup procedures, and appliance hardening. Mastery of network-level protocols, including HTTP, MQ, and FTP connectivity, remains critical for optimizing high-availability traffic routing and infrastructure throughput within enterprise service buses.
