400 AEM Interview Questions with Answers 2026
Course Description
Adobe Experience Manager (AEM) Developer & Architect Interview Practice Questions are meticulously designed to bridge the gap between theoretical knowledge and the high-pressure environment of technical interviews and certification exams. Whether you are navigating the complexities of AEM as a Cloud Service (AEMaaCS), optimizing Dispatcher configurations, or architecting headless solutions with Content Fragments and GraphQL, these practice tests provide a rigorous simulation of the challenges faced by modern Adobe professionals. We go beyond simple rote memorization by focusing on the "why" behind every architectural decision, covering everything from the underlying Oak/JCR repository and Sling Models to advanced Multi-Site Manager (MSM) strategies and Cloud Manager CI/CD pipelines. This course is your definitive toolkit for mastering the Adobe Experience Cloud ecosystem, ensuring you can confidently explain mutable vs. immutable partitions, implement secure OAK indexing, and deploy scalable components using HTL and the SPA Editor.
Exam Domains & Sample Topics
Core Architecture: OSGi R7, Apache Sling, Jackrabbit Oak, and JCR Node Types.
Development: Sling Models, HTL (Sightly), ClientLibs, and Core Components.
Cloud Operations: AEMaaCS, Cloud Manager, Dispatcher, and Asset Compute.
Content Strategy: MSM, Live Copies, Experience Fragments, and Content Fragments.
Security & Integration: SAML/OKTA, ACLs, GraphQL, and Adobe Target/Analytics.
Sample Practice Questions
1. In AEM as a Cloud Service, where should developer-defined OSGi configurations and custom code be stored to comply with the immutable repository structure? A. /apps B. /libs C. /conf D. /var E. /etc F. /content
Correct Answer: A
Overall Explanation: AEMaaCS enforces a strict separation between mutable and immutable content. The /apps and /libs directories are considered immutable and are locked at runtime. Custom code and configurations must be deployed via Cloud Manager into /apps.
A is Correct: /apps is the designated immutable area for custom application code and OSGi configs.
B is Incorrect: /libs is reserved for Adobe’s default product code; developers should never modify this.
C is Incorrect: /conf is for runtime configurations and is generally considered mutable.
D is Incorrect: /var is for transient system data and is mutable.
E is Incorrect: /etc is deprecated for many uses in AEMaaCS and is not for code deployment.
F is Incorrect: /content is for actual page and asset data (mutable).
2. Which Sling feature is responsible for mapping an incoming HTTP request URL to a specific JCR resource? A. Sling Models B. Sling Resource Resolver C. Sling Servlet D. Sling Adapter Factory E. Sling Health Check F. Sling Filter
Correct Answer: B
Overall Explanation: The Resource Resolution process is the heart of Sling. It translates a URL into a Resource object by checking resource mappings and the JCR tree.
A is Incorrect: Sling Models are used to map Resources to Java POJOs, not for URL resolution.
B is Correct: The Resource Resolver uses ResourceResolver.getResource() to find the node matching the URL.
C is Incorrect: A Servlet handles the request after the resource has been identified.
D is Incorrect: Adapters transform one object type to another (e.g., Resource to Node).
E is Incorrect: Health Checks monitor system status, not request routing.
F is Incorrect: Filters intercept requests but do not perform the primary URL-to-resource mapping.
3. When using Multi-Site Manager (MSM), what happens to a component on a Live Copy page if a "Cancel Inheritance" action is performed? A. The component is deleted immediately. B. The component becomes read-only. C. The component is moved to the /etc/blueprints folder. D. The synchronization between the Blueprint and the Live Copy for that component is broken. E. The component is automatically pushed to the Publish environment. F. The entire page inheritance is cancelled.
Correct Answer: D
Overall Explanation: Cancelling inheritance allows local authors to modify a specific component without those changes being overwritten by the Blueprint during a rollout.
A is Incorrect: The component remains on the page; only the link to the source is severed.
B is Incorrect: It becomes editable, the opposite of read-only.
C is Incorrect: Components are never moved to /etc during this process.
D is Correct: This action stops the Rollout Config from updating that specific resource.
E is Incorrect: MSM actions are author-side and do not trigger automatic replication to Publish.
F is Incorrect: Inheritance can be cancelled at the component level without affecting the rest of the page.
