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.

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.

Explanation
Adobe Client Data Layer is a JavaScript library that provides a standardized way to collect, structure, and manage data on a web page. It can be used to implement an event-driven data layer for analytics solutions. It integrates with Core components and allows authors to configure data layer properties for each component. It also supports custom events and data sources. References:

Explanation
A content fragment is a reusable piece of content that can be authored and managed independently from a page. Content fragments are based on structured data models that define the elements and data types of the content. Content fragments can be delivered as JSON using various APIs, such as Assets HTTP API, Content Fragments REST API, or Content Fragments GraphQL API. Content fragments are suitable for creating multi-channel applications that use AEM as a headless CMS. References:
