NEW QUESTION # 47
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 # 48
A developer needs to enable asynchronous indexing of multiple properties.
Which type of index should the developer use?
Answer: B
Explanation:
Comprehensive Explanation
A Lucene index is the appropriate choice for asynchronously indexing multiple properties in Adobe Experience Manager.
AEM uses Apache Jackrabbit Oak as its repository implementation. Oak supports several index types, but Lucene indexes are particularly suitable for complex queries involving multiple properties, full-text searches, and structured content filtering.
A Lucene index is defined under /oak:index with an index definition specifying its indexed properties, applicable node types, and operational settings. Asynchronous indexing can be enabled through the async property, allowing repository changes to be processed independently of the original content-writing transaction.
This architecture reduces the overhead associated with maintaining complex indexes during content modifications. However, asynchronous indexes are eventually consistent, meaning that recently committed changes may not immediately appear in query results.
Option A is unsuitable because the historical Ordered index is not the recommended mechanism for modern AEM indexing requirements. Option C refers to a Property index, which is generally appropriate for simpler property-based equality queries rather than complex asynchronous indexing.
Adobe recommends Lucene-based indexes for custom indexing requirements, with carefully defined index rules and property definitions to maintain query efficiency.

NEW QUESTION # 49
A developer is troubleshooting a component in AEMaaCS and needs to compare its properties in the development environment with those in the production environment.
Which action should the developer take next to compare the two environments?
Answer: B
Explanation:
Comprehensive Explanation
Adobe Experience Manager as a Cloud Service provides the Repository Browser as a diagnostic tool for examining repository resources and their stored properties across different environments.
The Repository Browser offers read-only access to the content structure of AEM environments, including Development, Stage, and Production.
To compare component properties, the developer accesses the AEM Developer Console through Cloud Manager and opens the Repository Browser for the appropriate environment and service tier.
The developer can navigate to the component's repository resource and inspect its stored properties, including sling:resourceType , component-specific configuration values, and other relevant JCR properties.
The same procedure can then be performed in the Production environment to identify differences.
Option A is incorrect because log files primarily contain execution and diagnostic messages rather than providing a complete view of stored component properties.
Option B is incorrect because the Developer Console's component-status information generally relates to OSGi components and runtime services, not the repository properties of an authored page component.
Option C directly supports the comparison required in the question.
Adobe documents the Repository Browser as a read-only tool accessible through the Developer Console. This design enables production troubleshooting without allowing developers to modify repository content.

NEW QUESTION # 50
A developer must create a new AEM project archetype that uses Adobe Managed Services.
Which property must be set while generating the project?
Answer: C
Explanation:
Comprehensive Explanation
The AEM Project Archetype uses the aemVersion property to determine the target Adobe Experience Manager runtime environment for the generated project.
When generating a project intended for Adobe Managed Services (AMS), developers must specify a compatible AEM 6.5 version rather than selecting the Cloud Service target.
For example:
-DaemVersion=6.5.8
Adobe explicitly documents 6.5.8 as an example value for Adobe Managed Services or on-premises environments. The actual value should correspond to the AEM version targeted by the implementation.
If aemVersion is not specified, current archetype versions default to cloud , which generates an AEM as a Cloud Service-oriented project.
Option A controls the generated Java source package and does not identify the target AEM runtime.
Option B specifies the Maven project version, commonly initialized with a snapshot value.
Option C specifies an AEM SDK version when targeting the Cloud Service environment. It does not determine whether the project is intended for Adobe Managed Services.
The aemVersion property influences generated dependencies and deployment-related configuration. It is therefore essential when targeting an AMS environment rather than AEM as a Cloud Service.

NEW QUESTION # 51
A developer wants to view response times for page transactions.
Which log file should they use?
Answer: B
Explanation:
Comprehensive Explanation
Adobe Experience Manager maintains an HTTP request log that records incoming requests and their corresponding responses, including response times.
The request.log file is particularly useful for identifying slow page requests, diagnosing performance problems, and evaluating application responsiveness.
Each request receives an identifier that associates the incoming HTTP request with its corresponding response. The response record includes the HTTP status code, content type, and processing time.
For example:
09:43:41 [66] - > GET /content/site/en.html HTTP/1.1
09:43:41 [66] < - 200 text/html 797ms
In this example, AEM required 797 milliseconds to process the request.
Option A is incorrect because audit.log primarily records auditing information, such as content-related administrative and moderation activities.
Option B is incorrect because stdout.log captures standard-output messages, including startup-related information, rather than providing the dedicated request timing records.
Option C is correct because request.log provides a direct mechanism for analyzing HTTP response times.
Adobe recommends using request-log analysis to identify slow pages, evaluate request concurrency, and diagnose application performance bottlenecks.
For extensive performance investigations, developers can aggregate response times by URL and correlate slow requests with thread dumps, repository query performance, and application logs.
