The Adobe AD0-E137 exam validates your expertise as an Adobe Experience Manager Sites Developer Expert. This certification is designed for developers who have hands-on experience building, configuring, and maintaining solutions within Adobe Experience Manager. This page provides a structured study roadmap covering the core domains, question formats, and practical preparation strategies you need to pass with confidence. Whether you're advancing your career or deepening your AEM skills, understanding the exam structure and content focus will help you allocate study time effectively.
Use this topic map to guide your study for Adobe AD0-E137 (Adobe Experience Manager Sites Developer Expert) within the Adobe Experience Manager path.
The AD0-E137 exam uses multiple-choice and scenario-based questions to assess both theoretical knowledge and practical decision-making. Questions progress in difficulty and reflect real-world situations you will encounter as an AEM developer.
Questions are weighted toward practical application, so understanding not just "what" but "why" and "when" to use each technique is essential for success.
A structured study plan that maps topics to weekly goals and includes hands-on practice will maximize your readiness. Allocate time proportionally to each domain, but prioritize areas where you have less real-world experience. Regular practice with realistic questions and timed reviews will build confidence and improve your pacing on exam day.

AEM Development and Build and Deployment typically represent the largest portion of the exam, reflecting the hands-on nature of the role. However, all four domains are tested, so a balanced study approach is essential. Review the official exam guide to confirm current weighting and adjust your study schedule accordingly.
These domains form a complete developer workflow: you develop components and features (AEM Development), configure them for your environment (Configurations), package and deploy them (Build and Deployment), and then monitor and troubleshoot them in production (Environment Maintenance). Understanding these connections helps you answer scenario-based questions and apply knowledge in your daily work.
At least 18-24 months of practical AEM development experience is recommended. Prioritize labs that cover component creation, template design, OSGi configuration, Maven builds, and package deployment. If possible, set up a local AEM instance and work through real-world tasks like fixing a broken dispatcher rule or deploying a feature package.
Common pitfalls include confusing HTL syntax with other template languages, misunderstanding dispatcher caching rules, and overlooking security considerations in configurations. Many candidates also rush through scenario questions without fully analyzing the requirements. Take time to read each question completely and consider edge cases before selecting your answer.
In your final week, focus on weak areas identified in practice tests rather than re-reading notes. Complete one full-length timed mock exam to build stamina and pacing. Review explanations for any questions you missed, and create a quick reference sheet for formulas, commands, and key terminology. On the day before the exam, do light review only; rest is more valuable than cramming.
A developer is asked to create an Adobe Experience Manager servlet MyServlet that listens for HTTP requests capable of handling the GET method. The servlet must be registered using Declarative Services (OSGi) and be bound to a specific resource type /my/resourcetype allowing it to serve requests for a particular component.
What is the correct way to register a servlet?
A)
@SlingServletResourceTypes(resourceTypes ="/my/resourcetype", methods = {"get"})
public class MyServlet extends SlingSafeMethodServlet {
@Override
protected void doGET(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {
// Handle get request
}
}
B)
@SlingServletResourceTypes(resourceTypes="/my/resourcetype", methods = { "GET" })
public class MyServlet extends SlingAllMethodsServlet {
@Override
protected void doGet(SlingHttpServletRequest request, SlingHttpServletResponse response) throws ServletException, IOException {
// Handle get request
}
}
C)
@SlingServletResourceTypes(resourceTypes ="/my/resourcetype", methods = { "get" })
public class MyServlet extends SlingSafeMethodServlet {
@Override
protected void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
// Handle get request
}
}
