NEW QUESTION # 21
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. Dynamic Participant Step
- B. Form Participant Step
- C. Workflow Initiator Participant Chooser
- D. Dialog Participant Step
Answer: A
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 # 24
A customer is having trouble with some search queries and provides the following information:
* The logs show the following warning occurs many time: WARN* Traversed 1000 nodes with filter Filter (query=select...)
* The client has more than 100,000 stored in their AEM instance
* The client uses a custom page property to help search for pages of a given type What should the AEM Developer do to help resolve the client's issue?
- A. Create a custom oak index for the custom page property.
- B. Set the reindex flag to true for node ''oakindex/cqPageLicen'
- C. Use the index Manager to validate the 'cqPageLicence index is enabled.
Answer: A
Explanation:
The warning WARN* Traversed 1000 nodes with filter Filter (query=select...) indicates that the query is performing a traversal instead of using an index. This results in poor performance, especially when the client has a large number of nodes (e.g., more than 100,000).
To resolve this issue, you should create a custom Oak index for the custom page property. This ensures that the queries can leverage the index for efficient data retrieval.
Steps to create a custom Oak index:
* Define the Oak Index:
* Navigate
to the /oak:index node in CRXDE Lite (http://localhost:4502/crx/de).
* Create a new node of type oak:QueryIndexDefinition.
* Configure the Index:
* Set the properties of the new index node to define the indexing rules for the custom page property.
{
"jcr:primaryType": "oak:QueryIndexDefinition",
"type": "property",
"propertyNames": ["customPageProperty"],
"reindex": true,
"async": "async"
}
* Deploy and Reindex:
* Save the changes and initiate a reindexing process.
* Ensure that the reindex flag is set to true for the newly created index.
* Validate the Index:
* Use the Index Manager or the AEM Web Console to validate that the new index is enabled and functioning correctly.
By creating a custom Oak index for the custom page property, the queries will be optimized to use the index, significantly improving the search performance and resolving the client's issue.

NEW QUESTION # 26
An AEM Developer needs to migrate to AEM as a Cloud Service from AEM version 6.4. The AEM Developer is not able to run the Best Practice Analyzer.
What is preventing the Best Practice Analyzer from running?
- A. The AEM Developer is not an admin or does not have administrator rights.
- B. Best Practice Analyzer is not supported on AEM version 6.4.
- C. Best Practice Analyzer should run on Publisher instead of Author instance.
Answer: A
Explanation:
The inability to run the Best Practice Analyzer (BPA) in AEM is most commonly due to the AEM Developer not having the necessary administrative rights. The Best Practice Analyzer is a tool that requires certain permissions to execute, typically administrative privileges.
Here's a detailed explanation:
* Administrator Rights Requirement: The Best Practice Analyzer tool needs access to various parts of the AEM system, including configuration settings and repository data, which require administrator-level permissions. Without these permissions, the tool cannot run properly.
* Permissions Check: Verify that the AEM Developer has admin rights. This can be done by checking the user roles in the AEM User Management console. Ensure that the user is part of the "administrators" group or has equivalent privileges.
* Running BPA: Once the correct permissions are in place, the developer can navigate to the Best Practice Analyzer tool in AEM and execute it. The BPA will then analyze the AEM instance for compliance with best practices.
* Version Compatibility: Note that while this specific issue is related to permissions, it's also important to ensure that the BPA tool version is compatible with the AEM version being used. In this case, the BPA supports AEM version 6.4 and above.
Steps to assign admin rights:
* Log into AEM: As an existing admin, log into the AEM instance.
* Navigate to User Management: Go to Tools > Security > Users.
* Add User to Admin Group: Find the user and add them to the "administrators" group.
* Save and Log Out: Save the changes and ask the user to log out and log back in to acquire the new permissions.
References:
* Adobe Best Practice Analyzer Documentation
* AEM User Management Documentation
These steps should resolve the issue and enable the AEM Developer to run the Best Practice Analyzer tool successfully.
NEW QUESTION # 27
A developer needs to create a workflow custom process step in AEM. In a custom process step, an OSGi component needs to implement the WorkflowProcess interface.
Which method should the developer implement?
- A. submit
- B. execute
- C. call
- D. apply
Answer: B
Explanation:
The WorkflowProcess interface is the interface to be used for automatic workflow steps implemented in Java.
Classes implementing this interface define Java based processes that can be attached to a WorkflowNode and executed by the workflow engine. The method execute takes a WorkItem, a WorkflowSession and a MetaDataMap as parameters and performs thelogic of the custom process step. References:

NEW QUESTION # 28
A new component called Page Headline needs to be implemented. The only difference to the title component delivered by Adobe's WCM core components is that the text needs to be taken from the current page title instead of jcr.title.
How should a developer implement this request?
A)
1. Create custom component
2. Implement Sling Modal as follows
B)
1. Create proxy component from the core title component
2. Implement sling Model as follows
C)
1. Create proxy component from the core title component
2. Implement Sling Model as follows
- A. Option C
- B. Option B
- C. Option A
Answer: A
Explanation:
To implement a new component called "Page Headline" which takes the text from the current page title instead of jcr:title, you should create a proxy component from the core title component and implement a Sling Model accordingly. Option C demonstrates the correct approach to achieve this functionality.
Here is a detailed explanation of Option C:
* Create Proxy Component:
* Create a new component in your project that will act as a proxy to the core title component. This involves creating a new component node in the repository that inherits from the core title component.
* Example path: /apps/myproject/components/pageHeadline with sling:resourceSuperType set to core/wcm/components/title/v2/title.
* Implement Sling Model:
* Implement a Sling Model that adapts from SlingHttpServletRequest and Title.class, ensuring it
* overrides the text fetching logic to retrieve the title from the current page's title.
* The model will use @ScriptVariable to inject the current page and @Self to access the core title component's logic.
@Model(adaptables = SlingHttpServletRequest.class, adapters = Title.class, resourceType =
"myproject/components/pageHeadline")
public class PageHeadline implements Title {
@ScriptVariable
private Page currentPage;
@Self @Via(type = ResourceSuperType.class)
private Title title;
@Override
public String getText() {
return currentPage.getTitle();
}
@Override
public String getType() {
return title.getType();
}
}
* @Model Annotation: Specifies that this class is a Sling Model and adapts from SlingHttpServletRequest. It is also an adapter for Title.class and applies to the myproject/components/pageHeadline resource type.
* @ScriptVariable: Injects the current Page object, which allows access to the current page's properties.
* @Self @Via(type = ResourceSuperType.class): Injects the core title component, allowing the reuse of existing logic.
* getText() Method: Overrides the getText() method to return the title from the current page instead of the jcr:title.
* getType() Method: Delegates to the core title component's getType() method to maintain existing functionality.
This approach leverages the power of Sling Models and the core components to extend functionality while keeping the implementation clean and maintainable.

NEW QUESTION # 29
A developer is on an AEM application that is being used to calculate an employee's salary. The calculation is done in an OSGi service called CalculationService. This service class has a dependency on one other service, called the EmployeeService.
How should the developer make sure that the critical code in the CalculationService has a high unit test coverage?
- A. Use a mock framework in the unit test to inject the CalculationService
- B. Use the feature flag in the unit test to disable the calls to the EmployeeService
- C. Use a mock framework in the unit test to inject the EmployeeService
- D. Instantiate the EmployeeService in the unit test and pass it to the constructor of the CalculationService
Answer: C
Explanation:
A mock framework is a tool that allows creating mock objects that simulate the behavior of real objects in a controlled way. A mock framework can be used in a unit test to inject the EmployeeService dependency into the CalculationService and verify its interactions. This way, the unit test can focus on testing the logic of the CalculationService without relying on the actual implementation of the EmployeeService.References:

NEW QUESTION # 30
In a non-optimized website, the final HTML generated for a typical page by publish instance includes a relatively large number of <script> elements that refer to other script files loaded from AEM environment. The developer wants to minimize these network calls by combining all required client library code into a single file to reduce the number of back-and-forth requests on page load.
Which step should a developer take to solve this issue?
- A. Embed the required libraries into an app-specific client library using the allowProxy property of the cq:Clientl_ibraryFolder node
- B. Embed the required libraries into an app-specific client library using the embed property of the cq:ClientLibraryFolder node
- C. Embed the required libraries into an app-specific client library using the dependencies property of the cq:Clientl_ibraryFolder node
- D. Add the categories property of the cq:Clientl_ibraryFolder node into an app-specific client library folder
Answer: C
Explanation:
The embed property of the cq:ClientLibraryFolder node allows embedding code from a client library into another client library. At runtime, the generated JS and CSS files of the embedding library include the code of the embedded library. This reduces the number of network calls and improves performance. Embedding code is useful for providing access to libraries that are stored in secured areas of the repository. References:

NEW QUESTION # 31
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 OSGI models to export as yaml
2. Configure mime type in Apache Sling MIME Type Service - B. 1. Create Sling models to export as yaml
2. Configure mime type in Apache Sling MIME Type Service - C. 1. Create OSGI models to export as yaml
2. Configure mime type in Apache Sling Servlet/Script Resolver and Error Handler - D. 1. Create Sling models to export as yaml
2. Configure mime type in Apache Sling Referrer Filter
Answer: B
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.

- A. $[env:ENV_VAR_NAME]
- B. $[secret:ENV_VAR_NAME]
- C. $[secret:SECRET_VAR_NAME]
- D. $[env:SECRET_VAR_NAME]
Answer: C
Explanation:
This syntax allows the developer to reference a secret variable that is stored in the Cloud Manager UI under Environment Details > Variables. The secret variable name must start with a lowercase letter and can contain alphanumeric characters and underscores.References:

NEW QUESTION # 33
A development team is starting a new AEM project that is going to integrate with the Adobe Commerce platform. The developer needs to create a new AEM project using the Maven command line interface.
How can the 'mvn -B archetype:generate' command help the developer with the integration between AEM and Adobe Commerce?
- A. Using the property ,aemVersion=cloudl automatically provides a report with integration guidelines.
- B. Using the property 'commerceModule=AdobeCommerce' can provide a path to an external jar that integrates between the platforms.
- C. Using the property 'includeCommerce=y'1 the command will generate specific Commerce Core Components.
Answer: C
Explanation:
The includeCommerce property is a boolean flag that indicates whether to include Commerce Core Components in the project or not. If set to y, the command will generate a commerce module that contains specific Commerce Core Components and their dependencies. These components can be used to integrate AEM with Adobe Commerce platform or other commerce solutions. References:

NEW QUESTION # 34
How should a developer create a custom log configuration?
- A.
- B.
- C.
Answer: A
Explanation:
To create a custom log configuration in AEM, the developer should create an OSGi configuration file for the org.apache.sling.commons.log.LogManager.factory.writer component. This configuration file should be placed under the appropriate runmode-specific folder within the config directory.
Here is the detailed process:
* Create Configuration File:
* Create a new XML file named
org.apache.sling.commons.log.LogManager.factory.writer-<identifier>.xml in the config.<runmode> folder.
* The <identifier> can be any unique identifier for your custom log configuration.
* Specify Configuration:
* Add the necessary configuration properties within this XML file. For example:
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root
xmlns:sling="http://sling.apache.org/jcr/sling/1.0"
xmlns:jcr="http://www.jcp.org/jcr/1.0"
jcr:primaryType="sling:OsgiConfig"
org.apache.sling.commons.log.file="/var/log/custom.log"
org.apache.sling.commons.log.level="debug"
org.apache.sling.commons.log.pattern="\{0\}"
org.apache.sling.commons.log.names="[com.myproject.custom]" />
* Deploy Configuration:
* Save the configuration file and deploy it to the appropriate environment. The logging system in AEM will pick up this configuration and create a custom log file with the specified settings.

NEW QUESTION # 35
A customer adds third-party client libraries to add some features in an existing AEM application, which will significantly reduce performance.
How should the developer optimize the site?
- A. Embed client libraries to consolidate them into fewer files.
- B. Rebuild Client libraries.
- C. Debug third-party client lib and fix the code.
Answer: A
Explanation:
Explanation
Embedding client libraries is a technique that allows combining code from multiple client libraries into a single file. This reduces the number of network requests and improves performance. Embedding client libraries can be done by using the embed property of the cq:ClientLibraryFolder node and specifying the categories of the client libraries to be embedded. References:
https://experienceleague.adobe.com/docs/experience-manager-cloud-service/content/implementing/developing/fu
NEW QUESTION # 36
If multiple configurations for the same PID are applicable, which configuration is applied?
- A. The one that occurs first in the repository is applied.
- B. The last modified configuration 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. This is because the runmodes act as a filter to select the most specific configuration for a given environment. If there is a tie between two or more configurations with the same number of matching runmodes, the one that occurs first in the repository is applied.

NEW QUESTION # 37
A developer has multiple LDAP Authentication providers. The user is not required to pass the authentication test of the Authentication provider
* If authentication succeeds, control is returned to the caller; no subsequent Authentication provider down the list Is executed.
* If authentication fails, authentication continues down the list of providers.
What should be the JAAS Control flag value in Apache Jackrabbit Oak External Login Module configuration?
- A. REQUIRED
- B. OPTIONAL
- C. SUFFICIENT
- D. MANDATORY
Answer: C
Explanation:
The JAAS Control flag SUFFICIENT is used when you have multiple LDAP authentication providers and you want the following behavior:
* Immediate Return on Success:
* If authentication succeeds with the current provider, control is returned to the caller immediately, and no subsequent providers in the list are executed.
* This is efficient and reduces unnecessary processing if a user's credentials are successfully authenticated by one of the initial providers.
* Continue on Failure:
* If authentication fails with the current provider, the authentication process continues down the list of providers until a successful authentication occurs or all providers are exhausted.
* This ensures that all available providers are tried before authentication is ultimately denied.
The SUFFICIENT control flag is thus well-suited for configurations where multiple authentication providers are used, and only one successful authentication is needed to grant access.

NEW QUESTION # 39
A developer needs to create an OSGI service that is able to read a list of spoken languages from the configuration of the service. Theconfiguration file tanguageServicelmplefgjson' already exisls:
Which snippet should the developer use lo read the OSGi configurations?
- A.
- B.
Answer: B
Explanation:
To read a list of spoken languages from the configuration of an OSGi service, the correct snippet to use is Option B. This snippet demonstrates how to define and read the configuration properties using the OSGi R7 annotations (@ObjectClassDefinition and @AttributeDefinition), which are the recommended way for defining OSGi configurations in modern AEM projects.
Here is the detailed explanation of the snippet:
Option B Snippet Explanation:
* Component Definition:
@Component(
service = { LanguageService.class }
)
@Designate(ocd = LanguageServiceImpl.Config.class)
public class LanguageServiceImpl implements LanguageService {
This defines an OSGi component and designates a configuration class for it.
Configuration Interface:
@ObjectClassDefinition(
name = "Sample - Language Service",
description = "OSGi Service providing information about languages"
)
@interface Config {
@AttributeDefinition(
name = "Sample Languages",
description = "List of spoken languages"
)
String[] languages() default { "English", "Japanese" };
}
This defines the configuration interface with annotations to describe the configuration properties. The languages attribute is defined with a default value of {"English", "Japanese"}.
Activate Method:
private String[] languages;
@Activate
protected void activate(Config config) {
this.languages = config.languages();
}
* The activate method reads the configuration values and assigns them to the instance variable languages when the service is activated.
Here is the complete Option B code:
@Component(
service = { LanguageService.class }
)
@Designate(ocd = LanguageServiceImpl.Config.class)
public class LanguageServiceImpl implements LanguageService {
@ObjectClassDefinition(
name = "Sample - Language Service",
description = "OSGi Service providing information about languages"
)
@interface Config {
@AttributeDefinition(
name = "Sample Languages",
description = "List of spoken languages"
)
String[] languages() default { "English", "Japanese" };
}
private String[] languages;
@Activate
protected void activate(Config config) {
this.languages = config.languages();
}
// Additional methods to use the languages array
}
By using this approach, you ensure that your OSGi service can dynamically read and use the list of spoken languages specified in its configuration, making it adaptable to different environments and requirements.
