NEW QUESTION # 29
AEM SPA integration provides various design models. In an application the developer chooses to use AEM as a headless CMS without using the SPA Editor SDK framework.
What would be an advantage for this design model?
- A. The developer keeps control over the app by only enabling authoring in restricted areas of the app
- B. The developer has full control over the app.
- C. The content author can edit the app using AEM's content authoring experience.
- D. The SPA is compatible with the template editor
Answer: B
Explanation:
Explanation
AEM SPA integration provides various design models for different levels of authoring capabilities and developer control. In the design model where AEM is used as a headless CMS without using the SPA Editor SDK framework, the developer has full control over the app and can use any SPA framework or library.
However, this also means that the content author cannot edit the app using AEM's content authoring experience, the SPA is not compatible with the template editor, and the developer cannot enable authoring in restricted areas of the app.

NEW QUESTION # 30
Refer to the exhibit.
The current page has three children.
What is the final rendered html output for the code snippet?
- A.
- B.
- C.
Answer: B
Explanation:
Explanation
Option B is the final rendered html output for the code snippet. The code snippet uses the data-sly-list block statement to iterate over the child pages of the current page. The data-sly-list statement assigns each child page to a variable named page and provides an index variable named i. The code snippet then uses the data-sly-test block statement to check if the index is odd or even and applies a different CSS class accordingly. The code snippet also uses the data-sly-element block statement to create an HTML element with the name specified by the elementName variable. The code snippet also uses the data-sly-attribute block statement to add an attribute with the name specified by the attrName variable and the value specified by the attrValue variable. The code snippet also uses the data-sly-resource block statement to include a resource with the path specified by the page.path variable and the resourceType specified by the resourceType variable.

NEW QUESTION # 31
A developer needs to create a new Title component. The requirements are:
1. The layout must be the same as the Title core component
2. The text property must have the page title as prefix (e.g., Page Title - <component text>)
3. The component must be reusable
Which approach is recommended?
- A. 1. Create a Proxy Component of Title core component
2. Create a Custom Sling Model that overrides the default behavior
3. Customize the component template
B, 1. Create a custom component from scratch
2. Create a Custom Sling Model for the component that follows the requirement
3. Create a Model Exporter - B. 1. Create a Proxy Component from Title core component
2. Create a Custom Sling Model that overrides the default behavior
Answer: A
Explanation:
Explanation
A proxy component is a site-specific component that inherits from a core component and allows customization of the component name, group, dialog, and behavior. A proxy component can refer to any version of the core component by changing the sling:resourceSuperType property. A custom sling model can be used to implement the logic for adding the page title as prefix to the text property. A component template can be used to define the layout of the component.

NEW QUESTION # 33
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 EmployeeService
- B. Instantiate the EmployeeService in the unit test and pass it to the constructor of the CalculationService
- C. Use the feature flag in the unit test to disable the calls to the EmployeeService
- D. Use a mock framework in the unit test to inject the CalculationService
Answer: A
Explanation:
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 # 34
If multiple configurations for the same PID are applicable, which configuration is applied?
- A. The last modified configuration is applied.
- B. The configuration with the highest number of matching run modes is applied.
- C. The one that occurs first in the repository is applied.
- D. A configuration factory is created and all configurations are applied.
Answer: B
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 # 35
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,B
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 # 36
An AEM application wants to set up multi-tenancy using Adobe-recommended best practices and bind multiple configurations to it. Which of the following options is recommended?
- A. import org.osgi.service.metatype.annotations.AttributeDefinition;
import org.osgi.service.metatype.annotations.ObjectClassDefinition;
@ObjectClassDefinition(name = "My configuration") - B. @Component(service = ConfigurationFactory.class)
@Designate(ocd = ConfigurationFactorylmpl.Config.class, factory=true) - C. import org.apache.felix.scr.annotations.Component; @Component(label = "My configuration", metatype = true, factory= true)
- D. import org.osgi.service.component.annotations.Component; @Component(service = ConfigurationFactory.class)
Answer: B
Explanation:
Explanation
The @Component(service = ConfigurationFactory.class) @Designate(ocd =
ConfigurationFactorylmpl.Config.class,factory=true) option is recommended for creating a multi-tenancy configuration and binding multiple configurations to it. This option uses the OSGi R6 annotations to define a component that provides a service of type ConfigurationFactory and designates a class that contains the configuration properties. The factory=true attribute indicates that multiple configurations can be created for this component.

An AEM as a Cloud Service implementation customer wants content to be replicated as soon as the On Time and Off Times are reached.
What must the developer configure?
- A. Configure the Publish content tree via Workflow Models
- B. Enable On Time or Off Time via Page Properties
- C. Enable Auto Replicate via On Off Trigger Configuration
Answer: C
Explanation:
Explanation
The Auto Replicate via On Off Trigger Configuration is a feature that allows content to be replicated as soon as the On Time and Off Times are reached. This feature can be enabled by creating an OSGi configuration for the com.day.cq.wcm.core.impl.servlets.OnOffTimeServlet service. This service listens for changes in the On Time and Off Time properties of pages andtriggers replication accordingly. References:

NEW QUESTION # 38
A customer who is running an AEM application on premise reports that the application is slowing down over time and even crashes The issues seem to start occurring after a new production deployment. The AEM developer knows that the described symptoms could be caused by a memory leak.
Which two steps should be taken after confirming the problem is related to a memory issue? (Choose two.)
- A. Create a heap dump for analysis
- B. Create a thread dump for analysis
- C. Increase the cache ratio of the application
- D. Analyze the request log and make sure the number of requests are below the expected threshold
- E. Open the error log and look for messages with 'OutOfMemoryError'
Answer: A,B
Explanation:
Explanation
Creating a heap dump and a thread dump are two steps that should be taken after confirming the problem is related to a memory issue. A heap dump is a snapshot of the memory usage of the Java Virtual Machine (JVM) at a given point in time. A heap dump can be used to identify memory leaks, memory consumption patterns, and objects that occupy large amounts of memory. A thread dump is a snapshot of the state of all threads that are part of the JVM process. A thread dump can be used to identify deadlocks, blocked threads, and CPU-intensive threads. References:

NEW QUESTION # 41
What is the recommended path to override /libs standard functionality?
- A. /content
- B. /Iibs
- C. /conf
- D. /apps
Answer: D
Explanation:
Explanation
The recommended path to override /libs standard functionality is /apps. The /apps folder contains application-specific code and configuration that can extend or override the default functionality provided by
/libs. The /apps folder has precedence over the /libs folder, meaning that if there are two resources with the same path under both folders, the one under /apps will be used. References:

NEW QUESTION # 42
A snippet throws an exception at runtime:
@Model(adaptables = {Resource.class}) public class MyCustomModel {
(SSIingObject
private Resource resource;
What should the developer add to fix it?
- A. defaultlnjectionStrategy = DefaultlnjectionStrategy property to @Model Class annotation
- B. SlingHttpServletRequest.class to adaptables property of Model Class annotation
- C. (Optional annotation to page field
- D. throws Exception at the end of the init method declaration
Answer: A
Explanation:
Explanation
The developer should add the defaultInjectionStrategy = DefaultInjectionStrategy property to the @Model Class annotation to fix the snippet. The defaultInjectionStrategy property defines how the Sling Model handles missing or null values for the injected fields. By default, the Sling Model uses the REQUIRED injection strategy, which means that all fields must have a non-null value or else an exception is thrown. By setting the defaultInjectionStrategy property to OPTIONAL, the Sling Model allows null values for the injected fields and does not throw an exception. This way, if the page field is null because the resource is not a page, the Sling Model can still work without errors. References:

The following code is included in sling models inherited from interface com.adobe.aem.guides.wknd.core.models.Byline
- A.
- B.
- C.
- D.
Answer: A
Explanation:
Explanation
Option C is the correct implementation for the Sling Model. Option C 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 C also uses the @Inject annotation with the name parameter set to "./name" and "./occupations" to inject the values of the name and occupations properties into the name and occupations fields. Option C also uses the @Named annotation with the value parameter set to
"byline" to specify the name of the Sling Model that can be used in HTL scripts. References:

NEW QUESTION # 46
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 Referrer Filter - 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 OSGI models to export as yaml
2. Configure mime type in Apache Sling MIME Type Service
Answer: B
Explanation:
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 # 47
A developer needs to create a dynamic participant step where the participant is selected automatically at run time.
The developer decides to develop an OSGi service, which needs to implement the com.day.cq.workflow.exec.ParticipantStepChooser interface.
Which method should the developer implement from the com.day.cq.workflow.exec.ParticipantStepChooser interface?
- A. void getParticipant(Workltem workltem, WorkflowSession workflowSession, MetaDataMap metaDataMap)
- B. String getParticipant(Workltem workltem, WorkflowSession workflowSession, MetaDataMap metaDataMap)
- C. void getDynamicParticipant(Workltem workltem, WorkflowSession workflowSession, MetaDataMap metaDataMap)
- D. String getDynamicParticipant(Workltem workltem, WorkflowSession workflowSession, MetaDataMap metaDataMap)
Answer: D
Explanation:
Explanation
The com.day.cq.workflow.exec.ParticipantStepChooser interface is intended for implementations that will define the participant dynamically. This interface replaces the deprecated com.day.cq.workflow.exec.ParticipantChooser interface. The method getDynamicParticipant returns the dynamically resolved Principal id based on the work item, workflow session and metadata map parameters.

NEW QUESTION # 48
On package install content that is already present in the repos must not be overwritten and if not present in the repos it must not be removed.
Which import mode should the developer use?
- A. merge
- B. replace
- C. update
Answer: C
Explanation:
Explanation
The merge import mode is used to import content that is already present in the repository without overwriting it and without removing content that is not present in the package. This mode preserves existing content properties and nodes while adding new ones from the package. This mode is useful for incremental updates or initial content seeding. References:
