Selected AD0-E134 Adobe Experience Manager Questions Answers

When multiple configurations for the same PID are applicable, the configuration with the highest number of matching runmodes is applied. This is because the runmodes act as a filter to select the most specific configuration for a given environment. If there is a tie between two or more configurations with the same number of matching runmodes, the one that occurs first in the repository is applied.References:https://experienceleague.adobe.com/docs/experience-manager-65/deploying/configuring/configure-runmodes.html?lang=en#configuring-osgi-settings-per-runmode

The /enableTTL “1” configuration must be applied to enable re-fetching of cached items based on Cache Headers sent by AEM. This configuration enables the Time To Live (TTL) feature of dispatcher, which allows dispatcher to check the Cache-Control and Expires headers of the cached files and re-fetch them from AEM if they are expired.

When building out a project using the most recent AEM Archetype, the ui.frontend module is optional. The ui.frontend module is typically used for integrating front-end build processes, such as those involving npm, Webpack, or other front-end tooling. If your project does not require such front-end tooling, you can omit this module.

Here is a breakdown of the archetype modules:

it.launcher: This module is used for integration tests and is required if you need to run automated tests as part of your build process.

ui.frontend: This module includes front-end tooling and build processes. It is optional and can be omitted if your project does not involve complex front-end development.

ui.tests: This module includes unit and integration tests for the UI part of your AEM project. It is often required for testing purposes.

ui.content: This module includes the content structures and initial content for your AEM project. It is generally required to set up the content for your project.

AEM Development Best Practices

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.
