Explanation: To create Sling Models that can export data in a human-readable yaml format, the following steps are required: Create Sling models to export as yaml. Sling models are Java classes that can be used to represent resources in AEM. Sling models can use annotations to define how they can be adapted from a resource and how they can export data in different formats. To export data in yaml format, the Sling model class needs to use the @Model annotation with the resourceType parameter set to the resource type of the resource that the model represents. The Sling model class also needs to implement the org.apache.sling.models.annotations.Exporter annotation with the name parameter set to "jackson" and the extensions parameter set to "yaml". The Sling model class also needs to use the @JsonProperty annotation on the fields or methods that need to be exported in yaml format. Configure mime type in Apache Sling MIME Type Service. The Apache Sling MIME Type Service is an OSGi service that maps file extensions to MIME types and vice versa. To enable the yaml format for Sling models, the MIME Type Service needs to be configured with a new entry for the yaml extension and its corresponding MIME type, which is "application/x-yaml". This can be done by creating an OSGi configuration for the org.apache.sling.commons.mime.internal.MimeTypeServiceImpl service and adding the entry "yaml=application/x-yaml" to the mime.types property.

Correct Answer: BD

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.

Correct Answer: B

The Best Practice Analyzer 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. The Best Practice Analyzer is not supported on

AEM version 6.4 or earlier versions. The Best Practice Analyzer requires AEM version 6.5 or later to run.

Explanation: 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.

Correct Answer: A

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.

Correct Answer: C

This syntax allows the developer to reference a secret variable that is stored in the Cloud Manager UI under Environment Details > Variables. The secret variable name must start with a lowercase letter and can contain alphanumeric characters and underscores.
