This free platform offers practice questions and a scenario-based mock exam for the Forward-Deployed Engineer (FDE) role — an engineer who works directly with customers to debug issues, integrate systems, and deliver technical solutions. It includes 40 foundational practice questions across six topic areas (FDE fundamentals and communication, debugging and root-cause analysis, web APIs and HTTP status codes, version control and CI/CD, performance and deployment reliability, and security and data protection), plus a 50-question scenario-based mock exam covering realistic customer troubleshooting situations. Built and maintained by Isha Training Solutions as general FDE skills practice material. It is not an official certification from any third-party body.
