Adobe AD0-E122 - Study Material - Adobe Experience Manager Sites Developer Expert

AD0-E122 is the current exam for the Adobe Experience Manager certification from Adobe. It succeeds AD0-E116 and validates expert-level ability to build, configure, and maintain Adobe Experience Manager Sites. Rather than testing product trivia, it checks whether a developer can turn designs and business requirements into working AEM components, templates, services, and integrations that hold up in production.

The blueprint is organised around four areas. Configurations covers dispatcher rules, multi-tenancy, OSGi configuration, custom Oak indexes, and SAML and LDAP integration. AEM Development, the largest section, covers SPA structure, complex components built with HTL, Sling models and services, unit testing with mock data, custom workflows, third-party integrations, and headless or hybrid delivery. Build and Deployment addresses front-end and back-end dependency management and the correct use of project archetypes. Environment Maintenance covers managing AEM environments, release management, synchronising content and configuration between environments, and planning upgrades and repository migrations.

The intended candidates are senior AEM developers, technical leads, and junior architects who already work on the AEM platform day to day. Adobe's guidance for this developer role expects hands-on platform experience, advanced component development skills, a deep understanding of the MVC framework and AEM libraries, and a clear grasp of the AEM development life cycle, from local setup through Cloud Manager pipelines to live maintenance.

Preparation works best domain by domain. The Study4Pass practice test for AD0-E122 contains 50 questions mapped to these four areas, so you can work in study mode on one topic at a time and read the detailed explanation after every answer. When a concept is unclear, such as Sling resolution, dispatcher caching, or Oak indexing, use Ask AI inside the test engine to work through the underlying idea before moving on. Once your topic scores are steady, switch to timed mode to rehearse pacing and decision-making under exam conditions, then return to topic training for any domain that is still costing you marks.
