Secure exam system network architecture integrating registration stations, exam workstations, and centralized web services through a DMZ-protected infrastructure. Registration and exam stations at each site connect through a WAF/Firewall to a three-tier web application handling presentation, business logic, and integration layers. The integration layer orchestrates data flow between exam repositories, candidate databases, a central file server for images and diagrams, and a mainframe system that receives final answers and scores. This architecture demonstrates defense-in-depth security for high-stakes testing environments while maintaining seamless data synchronization across distributed exam sites. Fork and customize this diagram on Diagrams.so to adapt it for your institution's specific exam workflows and compliance requirements.
