NEW QUESTION # 29
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. throws Exception at the end of the init method declaration
- D. (Optional annotation to page field
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:

NEW QUESTION # 31
Which configuration must be applied to enable re-fetching of cached items based on Cache Headers sent by AEM?
- A. /enableTTLtrue
- B. /enableTTL "1"
- C. /autolnvalidate "1"
- D. /autolnvalidate true
Answer: B
Explanation:
Explanation
The /enableTTL "1" configuration must be applied to enable re-fetching of cached items based on Cache Headers sent by AEM. This configuration enables the Time To Live (TTL) feature of dispatcher, which allows dispatcher to check the Cache-Control and Expires headers of the cached files and re-fetch them from AEM if they are expired.

NEW QUESTION # 32
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 configuration with the highest number of matching run modes is applied.
- C. A configuration factory is created and all configurations are applied.
- D. The last modified configuration is 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 # 33
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. @Component(service = ConfigurationFactory.class)
@Designate(ocd = ConfigurationFactorylmpl.Config.class, factory=true) - B. import org.osgi.service.component.annotations.Component; @Component(service = ConfigurationFactory.class)
- C. import org.osgi.service.metatype.annotations.AttributeDefinition;
import org.osgi.service.metatype.annotations.ObjectClassDefinition;
@ObjectClassDefinition(name = "My configuration") - D. import org.apache.felix.scr.annotations.Component; @Component(label = "My configuration", metatype = true, factory= true)
Answer: A
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.

NEW QUESTION # 36
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. Enable Auto Replicate via On Off Trigger Configuration
- B. Enable On Time or Off Time via Page Properties
- C. Configure the Publish content tree via Workflow Models
Answer: A
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 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 getDynamicParticipant(Workltem workltem, WorkflowSession workflowSession, MetaDataMap metaDataMap)
- B. String getParticipant(Workltem workltem, WorkflowSession workflowSession, MetaDataMap metaDataMap)
- C. String getDynamicParticipant(Workltem workltem, WorkflowSession workflowSession, MetaDataMap metaDataMap)
- D. void getParticipant(Workltem workltem, WorkflowSession workflowSession, MetaDataMap metaDataMap)
Answer: C
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 # 39
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 from Title core component
2. Create a Custom Sling Model that overrides the default behavior - B. 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
Answer: B
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 # 40
The OSGi configuration is added to a runmode specific configuration "config.author.staging" in AEM as a Cloud Service. The application fails to read the configuration.
What is a possible cause of this issue?
- A. Only <service> specific OSGi configuration runmodes like "config.author" or "config.publish" are supported in AEM as a Cloud service.
- B. The custom OSGi configuration runmode used (i.e., "config.author.staging") is not supported in AEM as a Cloud service.
- C. OSGi configuration runmodes cannot be installed automatically on AEM as a Cloud Service. We need to install them as a package using the Package manager.
- D. AEM as a Cloud service does not support OSGi configuration runmodes.
Answer: A
Explanation:
Explanation
AEM as a Cloud Service does not support custom OSGi configuration runmodes, such as
"config.author.staging". Only <service> specific OSGi configuration runmodes, such as "config.author" or
"config.publish", are supported. These runmodes are used to apply configurations to specific services, such as author or publish. The <service> specific runmodes can be combined with environment variables to achieve different configurations for different environments. References:

NEW QUESTION # 41
An application development team needs to create a multi-channel application that uses AEM as a headless CMS Which feature should be used to maintain structured data for this application?
- A. Experience fragment
- B. Custom component
- C. Static template
- D. Content fragment
Answer: D
Explanation:
Explanation
A content fragment is a reusable piece of content that can be authored and managed independently from a page. Content fragments are based on structured data models that define the elements and data types of the content. Content fragments can be delivered as JSON using various APIs, such as Assets HTTP API, Content Fragments REST API, or Content Fragments GraphQL API. Content fragments are suitable for creating multi-channel applications that use AEM as a headless CMS. References:

NEW QUESTION # 42
A client is having issues with some query results:
* Many of the client's industry terms have the same meaning, and users do not always search the exact wording
* Many users search by typing in short phrases instead of exact keywords, ex:// "cats and dogs" What index analyzers should the AEM developer recommend?
- A. 1. Add a Synonym filter to the current indexes
2. Add a LowerCase filter to the current indexes - B. 1. Tokenize the current indexes with a Keyword tokenizer
2. Add a Mapping filter to the current indexes - C. 1. Add a Mapping filter to the current indexes
2. Add a Stop filter to the current indexes - D. 1. Add a Synonym filter to the current indexes
2. Add a Stop filter to the current indexes
Answer: A
Explanation:
Explanation
A Synonym filter can help to map different terms that have the same meaning, such as "cat" and "feline". A LowerCase filter can help to normalize the case of the terms, so that "cats and dogs" and "Cats and Dogs" are treated the same.
NEW QUESTION # 43
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 dependencies 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 allowProxy 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: A
Explanation:
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 arestored in secured areas of the repository. References:

NEW QUESTION # 44
The following anchor tag is not resolving:
<a href="item.path" >{item.name}</a>
Upon further inspection the developer notices that the link has no .html appended to the end of the URL What could be a potential fix for the issue?
- A.
- B.
- C.
- D.
Answer: C
Explanation:
Explanation
Option B is a potential fix for the issue. Option B uses the data-sly-attribute block statement to add the href attribute to the anchor tag. The data-sly-attribute statement uses an expression to append ".html" to the item.path value. This way, the link will have the correct extension and will resolve to the corresponding page.
