NEW QUESTION # 10
A custom component has one dialog field:
The developer needs to implement a Sling Model to perform a business logic on the authored value. The developer writes the following HTL snippet.
Which two implementations will support this HTL snippet? (Choose two.)
- A.
- B.
- C.
- D.
Answer: A,D
Explanation:
Explanation
Option B and Option D are two implementations that will support the HTL snippet. Option B uses the
@Model annotation with the adaptables parameter set to Resource.class. This allows the Sling Model to adapt from a resource object and access its properties using the ValueMap interface. Option B also uses the @Inject annotation with the name parameter set to "./text" to inject the value of the text property into the text field.
Option D uses the @Model annotation with the defaultInjectionStrategy parameter set to OPTIONAL. This allows the Sling Model to use optional injection for all fields and avoid null pointer exceptions if a property is missing. Option D also uses the @Inject annotation without any parameters to inject the value of the text property into the text field, using the field name as the default property name. References:

NEW QUESTION # 12
What is the correct order of resolution of OSGi configuration at Runtime?
- A. 1. Modifying a configuration in the Web console will take immediate effect as it takes precedence at runtime.
2. Modifying a configuration in /apps will take immediate effect
3. Modifying a configuration in /libs will take immediate effect, unless it is masked by a configuration in
/apps. - B. 1. Modifying a configuration in /libs will lake immediate effect, unless it is masked by a configuration in
/apps O 2. Modifying a configuration in /apps will take immediate effect
3. Modifying a configuration in the Web console will take immediate effect as it takes precedence at runtime. - C. 1. Modifying a configuration in /apps will take immediate effect
2. Modifying a configuration in the Web console will take immediate effect as it takes precedence at runtime.
3. Modifying a configuration in /libs will take immediate effect, unless it is masked by a configuration in
/apps. - D. 1. Modifying a configuration in the Web console will take immediate effect as it takes precedence at runtime.
2. Modifying a configuration in /libs will take immediate effect, unless it is masked by a configuration in
/apps.
3. Modifying a configuration in /apps will lake immediate effect.
Answer: A
Explanation:
The order of resolution for OSGi configurations at runtime in AEM is as follows:
* Web Console Configuration:
* Changes made through the OSGi Web Console take immediate effect and have the highest precedence. This is because these configurations are considered the most direct way to adjust OSGi settings at runtime.
* References:OSGi Configuration in AEM
* /apps Configuration:
* Configurations in the /apps directory take precedence over those in the /libs directory. This allows custom configurations to override the default configurations provided by AEM.
* References:AEM Project Structure
* /libs Configuration:
* Configurations in the /libs directory are the default configurations provided by AEM. They are overridden by any configurations in the /apps directory.
* References:AEM Configuration
By understanding this order, developers can effectively manage and prioritize their OSGi configurations to ensure the desired behavior of their AEM instances.
NEW QUESTION # 13
SPA components are connected to AEM components via the MapTo() method.
Which code should be used to correctly connect an SPA component called ItemList to its AEM equivalent?
- A. MapTo(ltemList)('project/components/content/itemList,,ltemListEditConfig);
- B. ItemList.MapToCproject/components/content/itemList1);
- C. ('project/components/content/itemList,).MapTo(ltemList,ltemListEditConfig);
- D. MapToCproject/cornponents/content/itemList^ltemListJtemListEditConfig);
Answer: B
Explanation:
The MapTo() method is used to map a SPA component to an AEM component by specifying the sling:resourceType of the AEM component as an argument. The MapTo() method should be called on the SPA component and not on a string. The secondargument of the MapTo() method is optional and can be used to provide an edit configuration for the SPA component.
NEW QUESTION # 14
An AEM developer is assigned a task to design a workflow. The workflow is supposed to collect data from the participant and then determine the reviewer/approver branch to proceed further.
Which workflow step should be used by the developer?
- A. Dialog Participant Step
- B. Dynamic Participant Step
- C. Form Participant Step
- D. Workflow Initiator Participant Chooser
Answer: B
Explanation:
To design a workflow that collects data from the participant and then determines the reviewer/approver branch to proceed further, the developer should use theDynamic Participant Step. This workflow step allows for dynamic determination of participants based on the data collected or any other logic implemented in the workflow.
Here's how to implement a Dynamic Participant Step in AEM:
* Create the Workflow Model:
* In AEM, navigate to Tools > Workflow > Models.
* Create a new workflow model or edit an existing one.
* Add Dynamic Participant Step:
* Drag and drop the Dynamic Participant Step into your workflow model.
* Configure the Dynamic Participant Step:
* Click on the Dynamic Participant Step and configure it by specifying the participant chooser class.
This class should implement the logic to determine the next participant.
@Component(service = ParticipantStepChooser.class, property = {
"service.description=Dynamic Participant Chooser"
})
public class CustomParticipantStepChooser implements ParticipantStepChooser {
@Override
public String getParticipant(WorkItem workItem, WorkflowSession workflowSession, MetaDataMap metaDataMap) {
// Custom logic to determine the participant based on workflow data
String reviewer = // logic to determine reviewer
return reviewer;
}
}
* Implement Participant Chooser Logic:
* The CustomParticipantStepChooser class should contain the logic to determine the next participant based on the workflow data. This can include reading workflow variables, making decisions based on conditions, or any other custom logic.
* Deploy and Test:
* Save the workflow model and test it by starting a new workflow instance. Ensure that the dynamic participant determination works as expected.
By using the Dynamic Participant Step, you can create flexible workflows that adapt to the data and context, ensuring that the appropriate participants are chosen dynamically.

NEW QUESTION # 16
Where should an AEM Developer add a front end dependency?
- A. package.json
- B. config.json
- C. settlngs.xml
- D. vault.xml
Answer: A
Explanation:
An AEM Developer should add a front-end dependency in the package.json file. The package.json file is a standard configuration file for managing dependencies in JavaScript projects, including those using npm or Yarn as package managers.
Here's how to add a front-end dependency:
* Open the package.json File: This file is typically located at the root of your project.
* Add the Dependency: Add the required front-end dependency under the dependencies or devDependencies section. For example, to add lodash as a dependency:
{
"name": "my-aem-project",
"version": "1.0.0",
"dependencies": {
"lodash": "^4.17.21"
}
}
Install the Dependency: Run the following command to install the new dependency:
npm install
* Verify Installation: Ensure that the dependency has been added to the node_modules directory and is listed in the package-lock.json file.
The package.json file is the central place to manage all front-end dependencies, making it easy to track, update, and share dependencies across the development team.
References:
* npm Documentation
* Managing Dependencies in AEM Projects
These steps ensure that the front-end dependencies are managed efficiently and consistently within the AEM project.

NEW QUESTION # 19
An AEM Developer receives requirements for Sling Models in a human-readable yaml format. A custom application needs to be built. The dependency is as shown:
- A. 1. Create Sling models to export as yaml
2. Configure mime type in Apache Sling MIME Type Service - B. 1. Create OSGI models to export as yaml
2. Configure mime type in Apache Sling Servlet/Script Resolver and Error Handler - C. 1. Create Sling models to export as yaml
2. Configure mime type in Apache Sling Referrer Filter - D. 1. Create OSGI models to export as yaml
2. Configure mime type in Apache Sling MIME Type Service
Answer: A
Explanation:
To create Sling Models that can export data in a human-readable yaml format, the following steps are required:
* Create Sling models to export as yaml. Sling models are Java classes that can be used to represent resources in AEM. Sling models can use annotations to define how they can be adapted from a resource and how they can export data in different formats. To export data in yaml format, the Sling model class needs to use the @Model annotation with the resourceType parameter set to the resource type of the resource that the model represents. The Sling model class also needs to implement the org.apache.sling.models.annotations.Exporter annotation with the name parameter set to "jackson" and the extensions parameter set to "yaml". The Sling model class also needs to use the @JsonProperty annotation on the fields or methods that need to be exported in yaml format.
* Configure mime type in Apache Sling MIME Type Service. The Apache Sling MIME Type Service is
* an OSGi service that maps file extensions to MIME types and vice versa. To enable the yaml format for Sling models, the MIME Type Service needs to be configured with a new entry for the yaml extension and its corresponding MIME type, which is "application/x-yaml". This can be done by creating an OSGi configuration for the org.apache.sling.commons.mime.internal.MimeTypeServiceImpl service and adding the entry "yaml=application/x-yaml" to the mime.types property.

NEW QUESTION # 25
If multiple configurations for the same PID are applicable, which configuration is applied?
- A. The last modified configuration is applied.
- B. The one that occurs first in the repository is applied.
- C. The configuration with the highest number of matching run modes is applied.
- D. A configuration factory is created and all configurations are applied.
Answer: C
Explanation:
Explanation
When multiple configurations for the same PID are applicable, the configuration with the highest number of matching runmodes is applied.
