NEW QUESTION # 23
A developer needs to create a runmode-specific OSGi configuration for an AEM as a Cloud Service implementation. In which location should the OSGi configuration be created?
- A. core project, (/core/.../config <runmode>) folder
- B. all project, (/all/.../config.<runmode>) folder
- C. ui.apps project (/apps/.../config.<runmode>) folder
- D. ui.config project, (/config/.../config.<runmode>) folder
Answer: D
Explanation:
Explanation
The ui.config project, (/config/.../config.<runmode>) folder is the location where the OSGi configuration should be created for a runmode-specific configuration for an AEM as a Cloud Service implementation. The ui.config project contains OSGi configurations that are deployed to /apps in the repository. The config.<runmode> folder specifies the runmode for which the configuration is applicable, such as author or publish.

NEW QUESTION # 24
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:

NEW QUESTION # 25
An AEM application development team is assigned a task to create an Event-Driven Data Layer implementation for an Analytics solution.
Which Adobe recommended best practice should the developer choose?
- A. Create a custom data layer and add each component template, and its properties to the data layer
- B. Use Adobe Client Data Layer and integrate with Core components.
- C. Use Adobe Experience Platform's data layer to integrate with AEM.
- D. Create an Adobe Cloud Service configuration to use third-party tool's data layer.
Answer: B
Explanation:
Explanation
Adobe Client Data Layer is a JavaScript library that provides a standardized way to collect, structure, and manage data on a web page. It can be used to implement an event-driven data layer for analytics solutions. It integrates with Core components and allows authors to configure data layer properties for each component. It also supports custom events and data sources. References:

NEW QUESTION # 26
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: A
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 # 27
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 On Time or Off Time via Page Properties
- B. Enable Auto Replicate via On Off Trigger Configuration
- C. Configure the Publish content tree via Workflow Models
Answer: B
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 # 28
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. Instantiate the EmployeeService in the unit test and pass it to the constructor of the CalculationService
- C. Use a mock framework in the unit test to inject the EmployeeService
- D. Use the feature flag in the unit test to disable the calls to the EmployeeService
Answer: C
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:

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 # 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.apache.felix.scr.annotations.Component; @Component(label = "My configuration", metatype = true, factory= true)
- B. import org.osgi.service.metatype.annotations.AttributeDefinition;
import org.osgi.service.metatype.annotations.ObjectClassDefinition;
@ObjectClassDefinition(name = "My configuration") - C. import org.osgi.service.component.annotations.Component; @Component(service = ConfigurationFactory.class)
- D. @Component(service = ConfigurationFactory.class)
@Designate(ocd = ConfigurationFactorylmpl.Config.class, factory=true)
Answer: D
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 # 37
Which configuration/section should be used to resolve the domain name by dispatcher?
- A. Configuration in filters.any
- B. Configuration in DNS
- C. Configuration in vhosts file
- D. Configuration in httpd.conf
Answer: B
Explanation:
Explanation
The configuration in DNS (Domain Name System) should be used to resolve the domain name by dispatcher.
The DNS resolves the domain names to the IP address of the web server that hosts the dispatcher. The dispatcher then matches the incoming request URL with the cached files or the AEM publish instances.
