About the AD0-E123 exam

How to earn the certification

Earns

Adobe Certified Professional - Adobe Experience Manager Sites DeveloperProfessional

The certification is valid for two years.

How to prepare for AD0-E123

1. 1

   Run author, publish and Dispatcher locally

   Install an AEM author and a publish instance with a Dispatcher in front. Publish a page, find it in the cache, then change it and watch the flush agent clear it.

2. 2

   Build one component end to end

   AEM Development is the largest domain. Proxy a core component, add a dialog field, read it in a Sling Model and render it with HTL, then add a workflow step that acts on the same page.

3. 3

   Open every module the archetype makes

   Generate a project from the AEM Project Archetype and read each module. Note what the core and all modules hold, and how the parent POM and build profiles change the build.

4. 4

   Rehearse a Cloud Service migration

   Read how the Best Practices Analyzer, the Content Transfer Tool and Cloud Acceleration Manager fit together. Then practise reading the error log and inspecting nodes in CRXDE Lite for the debugging questions.

5. 5

   Close with timed AD0-E123 runs

   Take the AD0-E123 practice test in Timed Mode once each domain is covered. For every miss, ask Brainy AI Assistant to show the configuration or code that makes the right answer work.
