NEW QUESTION # 34
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: B,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 # 35
Which property under /cache on dispatcher.any file identifies the directory where cached files are stored?
- A. /invalidate
- B. /cacheroot
- C. /docroot
- D. /statfile
Answer: B
Explanation:
Explanation
The /cacheroot property under /cache in the dispatcher.any file identifies the directory where cached files are stored. It is a relative or absolute path to the cache root directory. The dispatcher creates a subdirectory for each virtual host under this directory and stores thecached files there.

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. import org.apache.felix.scr.annotations.Component; @Component(label = "My configuration", metatype = true, factory= true)
- C. @Component(service = ConfigurationFactory.class)
@Designate(ocd = ConfigurationFactorylmpl.Config.class, factory=true) - D. import org.osgi.service.component.annotations.Component; @Component(service = ConfigurationFactory.class)
Answer: C
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
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.

What is Out of Scope for the Pattern Detector tool, while doing an AEM upgrade?
- A. Backward Compatibility with the previous AEM Version
- B. rep:User nodes compatibility (in context of OAuth configuration)
- C. Definitions of Oak indices for compatibility
- D. OSGi bundles exports and imports mismatch
Answer: A
Explanation:
Explanation
Backward Compatibility with the previous AEM Version is out of scope for the Pattern Detector tool, while doing an AEM upgrade. The Pattern Detector tool is a tool that scans an existing AEM code base and identifies patterns that are incompatible with AEM as a Cloud Service or newer versions of AEM on-premise.
