400 AEM Interview Questions with Answers 2026

Master AEM with Real-World Scenarios, Sling Models, and Cloud Service Best Practices.

Adobe Experience Manager (AEM) Interview Practice Questions and Answers is designed to bridge the gap between theoretical knowledge and the high-level technical expertise required to ace modern AEM interviews or certification exams. I have personally crafted this comprehensive question bank to cover everything from the "plumbing" of the Oak JCR and OSGi service lifecycles to the nuances of AEM as a Cloud Service (AEMaaCS), ensuring you understand not just the "how," but the "why" behind every architectural decision. By focusing on practical, scenario-based challenges involving HTL, Sling Models, Multi-Site Manager (MSM), and GraphQL-based headless implementations, I provide you with the deep-dive explanations needed to confidently discuss Dispatcher security, Asset Compute services, and Cloud Manager pipelines with any hiring manager or technical lead.

Exam Domains & Sample Topics:

• Core Architecture: OSGi, Sling Request Processing, Oak Indexing (Lucene), and JCR Node Types.

• Development: Sling Models, HTL, Core Components, SPA Editor, and ClientLibs.

• AEM as a Cloud Service: Dispatcher, Mutable/Immutable partitions, and Cloud Manager.

• Content Strategy: MSM, Live Copies, Experience Fragments, and Content Fragments.

• Advanced Integrations: Adobe Target, Analytics, GraphQL, and SAML Security.

Sample Practice Questions

• Question 1: A developer needs to ensure that a specific OSGi service configuration is applied only to the "author" runmode in an AEM as a Cloud Service environment. Where should this configuration be placed in the project structure?

  • A. /apps/my-project/config

  • B. /apps/my-project/config. author

  • C. /ui.config/src/main/content/jcr_root/apps/my-project/osgiconfig/config. author

  • D. /ui.apps/src/main/content/jcr_root/apps/my-project/config. prod

  • E. /conf/global/settings/osgi/config. author

  • F. /libs/system/config. author

  • Correct Answer: C

  • Overall Explanation: In AEMaaCS, OSGi configurations must be stored in the ui.config module using a specific folder naming convention (config.<runmode>) to ensure the Cloud Manager deployment engine applies them to the correct environment.

  • Detailed Option Explanations:

    • A: Incorrect. This would apply to all runmodes, not just author.

    • B: Incorrect. While this worked in older on-prem versions, AEMaaCS requires configurations to be in the ui.config module under the osgiconfig path.

    • C: Correct. This follows the standard AEM Project Archetype structure for cloud-ready runmode-specific configurations.

    • D: Incorrect. Configurations should reside in ui.config, not ui.apps, and .prod targets production, not author.

    • E: Incorrect. This path is generally used for editable templates and context-aware configs, not standard OSGi factory configs.

    • F: Incorrect. The /libs path is reserved for system code and is immutable; developers should never place configurations there.

• Question 2: When implementing a custom Sling Model for a component, which annotation is most appropriate to inject a resource property while ensuring the model remains adaptable from both a Request and a Resource?

  • A. @Inject

  • B. @ValueMapValue

  • C. @ScriptVariable

  • D. @OSGiService

  • @Self

  • F. @RequestAttribute

  • Correct Answer: B

  • Overall Explanation: @ValueMapValue is a specialized injector for Sling Models that specifically targets properties from the Resource's ValueMap, making it more efficient and readable than the generic @Inject.

  • Detailed Option Explanations:

    • A: Incorrect. While @Inject works, it is generic and less performant than the specific @ValueMapValue injector.

    • B: Correct. It is the best practice for injecting properties from the underlying JCR node into a Sling Model.

    • C: Incorrect. This is used for objects standardly available in HTL/JSP (like currentStyle or pageProperties), not JCR properties.

    • D: Incorrect. This is used to inject OSGi services, not content properties.

    • E: Incorrect. This injects the adaptable object itself (the Resource or Request).

    • F: Incorrect. This injects attributes explicitly set on the ServletRequest, not JCR node properties.

• Question 3: In AEM as a Cloud Service, which of the following is a "Mutable" path where content can be modified at runtime?

  • A. /apps

  • B. /libs

  • C. /content

  • D. /oak:index

  • E. /etc/clientlibs

  • F. /bin

  • Correct Answer: C

  • Overall Explanation: AEMaaCS uses a clear separation between immutable storage (/apps, /libs) which is read-only at runtime, and mutable storage (/content, /conf, /var, /home) where content and configurations can be changed.

  • Detailed Option Explanations:

    • A: Incorrect. /apps is immutable and can only be changed via a Cloud Manager deployment.

    • B: Incorrect. /libs is managed by Adobe and is strictly read-only.

    • C: Correct. /content is the primary location for authors to create and edit pages and assets at runtime.

    • D: Incorrect. While indexes can be updated, the definitions in /oak:index are treated as part of the code deployment in AEMaaCS.

    • E: Incorrect. ClientLibs under /etc are deprecated or moved; if they are in /apps, they are immutable.

    • F: Incorrect. System binaries and scripts are part of the immutable code base.
