In AEM as a Cloud Service, one notable change that developers should be aware of is the removal of replication agents. Instead of the traditional replication agents used in on-premise or AEM Managed Services environments, AEM as a Cloud Service uses a different mechanism to distribute content.

Key points about this change:

Content Distribution:

In AEM as a Cloud Service, content distribution is managed through automated processes that do not rely on manually configured replication agents.

The cloud infrastructure handles the replication and distribution of content to publish instances.

Publishing Model:

The publishing process is designed to be more seamless and integrated within the cloud environment, leveraging the underlying cloud services for scalability and efficiency.

Developers and administrators do not need to manually manage replication agents, simplifying the content deployment process.

Benefits:

This change reduces the complexity of content distribution in AEM projects.

It ensures higher reliability and performance by leveraging the capabilities of the cloud infrastructure.

Content Distribution in AEM as a Cloud Service

By understanding this change, developers can effectively manage content distribution in AEM as a Cloud Service and leverage the new mechanisms provided by the cloud platform.

To generate a test coverage report for an AEM project using the latest archetype, the correct plugin to use is the maven-surefire-plugin (Option A). The maven-surefire-plugin is a part of the Maven ecosystem and is widely used to run unit tests within a Maven project. This plugin can be configured to generate detailed test reports, including HTML versions, which can be easily shared with clients.

Here’s how to configure the maven-surefire-plugin to generate test coverage reports:

Add the Plugin to the POM File: Add the maven-surefire-plugin configuration in your pom.xml file:

org.apache.maven.plugins

maven-surefire-plugin

2.22.2

${project.build.directory}/surefire-reports

html

false

Execute the Maven Command: Run the following command to execute the tests and generate the coverage report:

mvn clean test

Locate the Report: The HTML test coverage report will be generated in the target/surefire-reports directory of your project.

Utilizing model props to drill down and access or set the state on desired components is the least complex approach for sharing information between Single Page Application (SPA) components in AEM.

Here’s why using model props is effective:

Simplicity: This approach leverages the existing component hierarchy and properties, making it straightforward to pass data between components.

Direct Access: Model props allow for direct access to the state and properties of parent or sibling components, enabling easy data sharing.

Minimal Setup: Unlike implementing a state library or customizing container components, using model props requires minimal additional setup, reducing complexity and potential overhead.

Steps to utilize model props for state management:

Define the State in the Parent Component: Ensure that the parent component maintains the state that needs to be shared.

Pass Props to Child Components: Pass the necessary state and any setter functions as props to the child components. For example, in a React-based SPA, you can do this using JSX syntax:

function ParentComponent() {

const [sharedState, setSharedState] = useState(initialState);

return (

);

}

Access and Modify State in Child Components: In the child components, access and modify the shared state using the props passed from the parent:

function ChildComponentA({ sharedState, setSharedState }) {

return (

);

}

By using this approach, you ensure a simple and effective way of managing and sharing state across components in your SPA, adhering to best practices for component-based architecture.

Extend the Teaser Component from Core Components

Create style variations to be used in the Style System** Comprehensive Explanation of Correct Answer Only: The Teaser Component from Core Components is a component that allows authors to display a title, description, image and link for a teaser item. The component supports multiple designs and can be extended to add custom features or logic. The Style System allows authors to define style variations for components without requiring code changes or new templates.

JUnit and Mockito are two unit testing dependencies that are generated by AEM archetype. JUnit is a framework for writing and running unit tests in Java. Mockito is a framework for creating and using mock objects in unit tests. AEM archetype also adds Apache Sling Mocks and AEM Mocks Test Framework by io.wcm as dependencies for unit testing.

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.

Code Quality Testing is a type of Cloud Manager tests that are enabled for all Cloud Manager production pipelines and cannot be skipped. Code Quality Testing checks the code quality of the project using SonarQube and reports any issues or vulnerabilities. Code Quality Testing can fail the pipeline if the code quality does not meet the minimum standards defined by Adobe.

AEM Assets HTTP API is a RESTful API that allows access to content fragments in JSON format without any customization. The API supports CRUD operations on content fragments and their variations, as well as querying and searching for content fragments based on metadata or full-text search.References:https://experienceleague.adobe.com/docs/experience-manager-65/assets/extending/assets-api-content-fragments.html?lang=en

Option C is the AEM dependency that provides APIs for all AEM environments. Option C uses the uber-jar dependency with the provided scope and the classifier set to apis. The uber-jar dependency contains all the public Java APIs that are available in AEM. The provided scope indicates that the dependency is not required for runtime, as it is already provided by the AEM platform. The apis classifier indicates that only the API classes are included in the dependency, not the implementation classes.

To ensure that text pasted inside the Text component in AEM is stripped of all styling and formatting, you need to override the RTE (Rich Text Editor) plugin implementation and change the default paste behavior. The correct option to achieve this is defaultPasteMode=plaintext.

Steps to configure the RTE plugin for plain text pasting:

Locate the RTE Configuration: Find the existing configuration for the RTE or create a new one in the /apps directory of your AEM project.

Modify the Plugin Configuration: Add or update the configuration to include the defaultPasteMode parameter. The configuration might look something like this:

{

"jcr:primaryType": "nt:unstructured",

"features": "[text]",

"defaultPasteMode": "plaintext"

}

Apply the Configuration: Ensure that this configuration is applied to the Text component. This typically involves updating the component dialog or design dialog to reference the updated RTE configuration.

Test the Configuration: In the AEM author instance, open the page with the Text component and paste text using CTRL+V. The pasted text should now be stripped of all styling and formatting, adhering to the plaintext mode.

By setting defaultPasteMode to plaintext, you ensure that the RTE only accepts plain text input, removing any formatting that might come from external sources.
