NEW QUESTION # 34
A developer needs to write a Java service that will provide data to a custom component. Which Maven module is the appropriate place to create this service?
Answer: A
Explanation:
Comprehensive Explanation
The core module in an AEM Maven project is responsible for Java-based application functionality, including OSGi services, Sling Models, servlets, event listeners, schedulers, and other backend implementations.
When a developer creates a Java service to provide data to a custom component, the service should be implemented within the core module and registered using the appropriate OSGi component annotations.
For example:
@Component(service = ProductService.class)
public class ProductServiceImpl
implements ProductService {
// Business logic
}
The service can then be injected into a Sling Model using the appropriate dependency-injection mechanism.
The model exposes the processed information to the component's HTL rendering script.
Option B is incorrect because content modules are intended for repository content and configuration resources rather than compiled Java service implementations.
Option C refers to the application-resource module, commonly named ui.apps in the AEM Project Archetype.
This module stores component definitions, HTL scripts, client libraries, dialogs, and other repository-based application resources.
Keeping Java logic within the core module supports separation of concerns, reusable services, independent unit testing, and proper OSGi bundle packaging.
Adobe's official archetype documentation explicitly identifies the core module as the location for Java-based OSGi services and other backend functionality.

NEW QUESTION # 35
A developer needs to determine whether a publication is pending or blocked.
Where can this information be located?
Answer: B
Explanation:
Comprehensive Explanation
Adobe Experience Manager provides Replication Agent Status information for monitoring publication requests and identifying replication-queue problems.
In AEM 6.5, developers and administrators can inspect replication agents through the Replication console, available from the Author environment.
Each replication agent exposes configuration details, operational status, queue information, and relevant diagnostic information.
Adobe documents several replication-queue states, including Active, Idle, and Blocked.
An Active queue is processing replication requests. An Idle queue contains no outstanding requests. A Blocked queue contains requests that cannot currently be processed, potentially because the receiving Publish instance is unavailable, network connectivity has failed, or transport authentication is unsuccessful.
The replication queue also identifies pending requests, enabling administrators to determine which content has not yet completed publication.
Option B is incorrect because publish.log is not the standard AEM location for determining replication-agent queue status.
Option C is plausible because replication logging can provide useful diagnostic information. However, the agent's queue-status interface is the more direct location for determining whether publication requests are pending or blocked.
Option D is incorrect because Dispatcher-related status information concerns caching and request delivery rather than the Author-to-Publish publication queue.
Adobe recommends inspecting replication-agent queues when diagnosing failed or delayed publication operations.

NEW QUESTION # 36
An Adobe Experience Manager developer needs to identify issues involving client-side events associated with a UI button. The developer intends to use the client library for debugging.
What should the developer do first?
Answer: C
Explanation:
Comprehensive Explanation
Adobe Experience Manager provides client-library debugging functionality to help developers inspect JavaScript and CSS resources included through the AEM client library system.
Client libraries frequently combine and minify multiple JavaScript and CSS files to improve production performance. This optimization can make it difficult to determine which source file contains a defective event handler.
Adobe documents the debugClientLibs=true query parameter as a mechanism for examining the underlying files embedded within client libraries.
The developer can append this parameter to the page URL:
/content/mysite/en/home.html?debugClientLibs=true
After reloading the page, the developer can inspect the generated client-library references to identify the original source files and troubleshoot the relevant JavaScript.
Option B is incorrect because examining repository configuration folders is not the most direct approach for diagnosing client-side event behavior.
Option C primarily supports debugging Adobe Experience Cloud and Experience Platform integrations rather than general component event handlers.
Option D can assist with investigating failed network requests, but it does not specifically activate AEM client-library debugging.
Qualification: Enabling debugClientLibs does not itself identify a faulty button event handler. The developer should subsequently use browser developer tools, JavaScript breakpoints, and event-listener inspection to isolate the problem.

NEW QUESTION # 37
A front-end developer working on an AEM SPA project cannot view the property that should be exposed in the JSON for a newly created component, which was then added to the homepage (page-name.html).
Which option would provide information about whether the required property is exposed by the Sling Model?
Answer: C
Explanation:
Comprehensive Explanation
Adobe Experience Manager supports exposing structured component data through the Sling Model Exporter, which serializes Sling Model properties into JSON representations.
In an AEM Single Page Application (SPA) implementation, the frontend application consumes exported component data to render the user interface.
The .model.json selector provides access to the JSON representation generated by the Sling Model Exporter.
For example, a homepage located at /content/mysite/en/home.html can expose its exported model through:
/content/mysite/en/home.model.json
The developer can inspect this response to determine whether the custom component and its expected property are included in the exported model.
Option A correctly uses the .model.json selector.
Option B is incorrect because /sling.json is not the documented endpoint for the page's Sling Model Exporter representation.
Option C is incorrect because /sling-model.json does not follow the required selector structure.
If the property is absent, the developer should inspect the Sling Model's exported getters, annotations, implementation, component resource type, and the frontend component mapping.
The developer must also confirm that the relevant component is present in the page model and that the exported property is not explicitly excluded from JSON serialization.
This diagnostic method allows the frontend and backend implementations to be evaluated independently.

NEW QUESTION # 38
A developer reviews an AEM start script on the server and finds that the CQ_JVM_OPTS parameter is set to:
"-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n"
How does this value affect startup of the AEM instance?
Answer: B
Explanation:
Comprehensive Explanation
The -agentlib:jdwp Java Virtual Machine parameter activates the Java Debug Wire Protocol (JDWP), enabling a debugger to connect to a running Java process.
In Adobe Experience Manager, this configuration is commonly used when debugging Java code through an IDE such as Eclipse or IntelliJ IDEA.
The parameter transport=dt_socket specifies socket-based communication between the JVM and debugging client.
The address=8000 setting identifies the port used for debugger connections, while server=y instructs the JVM to listen for incoming debugger connections.
The suspend=n setting is particularly important because it allows the AEM instance to continue starting without waiting for a debugger to attach.
Option A is incorrect because suspending startup would require suspend=y . Even then, startup would wait for a debugger rather than necessarily fail.
Option C is incorrect because the debug-agent settings do not determine the AEM instance's Author or Publish run mode.
Option B correctly identifies that the instance starts with remote debugging enabled.
Technical distinction: Remote JVM debugging is different from setting the AEM application log level to DEBUG . The JDWP parameter enables debugger attachment, breakpoints, and Java execution inspection.
Adobe recommends avoiding unnecessary remote debugging in production because it can introduce performance and security risks.
