Free Practice Questions for Adobe AD0-E137 Exam

The issue in this case is that the title field is declared but not annotated with @Inject. In Sling Models, all fields that should be populated from the resource or request must be annotated appropriately (@Inject, @ValueMapValue, or @Self). Without this annotation, the Sling Model cannot populate the field when adapting from the resource, resulting in the model not functioning as expected. Option A is incorrect because Resource.class is a valid adaptable for Sling Models. Option C does not apply because the problem is not with hard-coded paths but with injection. Option D is also incorrect because while @PostConstruct must be properly annotated, the root issue here is missing injection on the field. Adobe’s Sling Models documentation emphasizes correct use of injection annotations as a core requirement.

To optimize queries against DAM assets with custom properties, developers must extend the existing damAssetLucene index. The correct method is to add the custom property under:

oak:index/damAssetLucene/indexRules/dam:Asset/properties. This ensures that the property is indexed for all assets and avoids traversal queries. Option B refers to a non-existent lucene index path, and Option C incorrectly suggests adding a property value (Hello) instead of the property name. Adobe’s indexing guidelines specify that extending existing Lucene indexes such as damAssetLucene is the standard approach for asset-related queries. This ensures queries remain efficient, scalable, and compatible across environments.

Explanation (Adobe Docs Reference):

Editable templates + Policies: Editable templates allow developers to restrict which components are available by defining policies that control allowed components for layout containers.

Content Fragment Model validation: Developers can define validation rules (e.g., regex, required fields, min/max length) directly in the content fragment model.

Options A, C, and D are incorrect:

Field validation is not configured in editable templates (A is wrong).

Workflows are not used for enforcing component usage (C is wrong).

Dynamic templates are deprecated in favor of editable templates (D is wrong).

Adobe Documentation:

“Editable templates support defining policies to determine which components can be used in the layout container.”

— AEM Templates – Defining Policies

“Content Fragment Models can include validation rules to ensure data integrity, including regex patterns, length restrictions, and required fields.”

In AEM as a Cloud Service, multi-tenant projects can be managed via independent repositories linked to a primary project repository using git submodules. When a new tenant is added, the tenant’s repository must be registered as a submodule of the main project so that it is included in the CI/CD build and deployment pipelines.

From Adobe Documentation:

“When using independent repositories for tenant modules, these repositories must be referenced as git submodules in the main project repository. This ensures they are included in the Cloud Manager build and deployment process.”

The recommended way to generate a new AEM project is by using the official Adobe AEM Maven Archetype. Developers must specify the correct groupId (com.adobe.aem) and artifactId (aem-project-archetype). The archetypeVersion should match the latest stable archetype version (e.g., 50 for AEM 6.5). The groupId of the project should be set to the organization’s package, in this case com.mysite. The appId defines the project name and should match the intended application (mysite). The version is defined as 2.0 to represent the project version, while aemVersion=6.5 ensures compatibility with AEM 6.5. Option A is invalid because the archetype groupId is incorrect and the values are mismatched. Option C contains placeholders and an invalid groupId. Adobe’s official documentation for generating projects specifies option B as the valid approach.
