QUESTION: 13

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.)

Answer(s): B,D

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.

QUESTION: 14

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?

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
1. Create a Proxy Component from Title core component
2. Create a Custom Sling Model that overrides the default behavior

Answer(s): A

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.

QUESTION: 15

A developer needs to create sling models for two fields name and occupations. The dialog has two fields, name - a single value field, and occupations - a multi value field. The following code is included in sling models inherited from interface com.adobe.aem.guides.wknd.core.models.Byline

Answer(s): C

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.

QUESTION: 16

SPA components are connected to AEM components via the MapTo() method. Which code should be used to correctly connect an SPA component called ItemList to its AEM equivalent?

('project/components/content/itemList,).MapTo(ltemList,ltemListEditConfig);
MapToCproject/cornponents/content/itemList^ltemListJtemListEditConfig);
ItemList.MapToCproject/components/content/itemList1);
MapTo(ltemList)('project/components/content/itemList,,ltemListEditConfig);

Answer(s): C

Explanation:

The MapTo() method is used to map a SPA component to an AEM component by specifying the sling:resourceType of the AEM component as an argument. The MapTo() method should be called on the SPA component and not on a string. The second argument of the MapTo() method is optional and can be used to provide an edit configuration for the SPA component.
