• Question 33:

  A developer is trying to decide whether to use a Core Breadcrumb component or develop a custom one. The business requirement is to have an identical Breadvrumb as the core, with an additional icon which is not part of the Core Breadcrumb component that will be uploaded from assets.

  Which decision should the developer make?

  A. Request Adobe to modify the Core Breadcrumb component, and then use it after modification
  B. Re-use the Core Breadcrumb, and then add a custom option to upload the asset.
  C. A new custom component needs to be developed
  C. A new custom component needs to be developed

  ---

  Explanation/Reference:

  Understand the Core Breadcrumb Component: The Core Breadcrumb component provided by Adobe is a standardized, out-of-the-box solution for displaying a breadcrumb trail. It includes default functionalities and styling which meet

  common requirements but does not support custom icons uploaded from assets directly.

  Business Requirement Analysis: The requirement is to have an identical breadcrumb as the core component but with an additional custom icon uploaded from the assets. This customization goes beyond the capabilities of the existing Core

  Breadcrumb component.

  Evaluate Modification Options:

  Requesting Adobe to Modify the Core Component: This option is not practical due to the time and effort involved in getting Adobe to make such a specific customization. Moreover, it may not align with Adobe's development roadmap or

  priorities.

  Reusing the Core Component with Custom Options: Although this approach could potentially save development time, it might lead to complexities in integrating custom upload functionality with the existing core component structure. This can

  also result in maintenance challenges during future updates to the core components.

  Developing a Custom Component: Given the specific need for custom icons uploaded from assets, developing a new custom component is the most viable solution. This approach ensures that the breadcrumb functionality is tailored exactly

  to the business requirement. The developer can start by leveraging the core component's code as a base and extending it to include the custom icon feature. This way, the business can achieve both the desired appearance and functionality.

  Implementation Strategy:

  Custom Component Creation: Create a new AEM component by extending the existing Core Breadcrumb component.

  Custom Icon Feature: Add functionality to upload an icon from the DAM (Digital Asset Management) and integrate it into the breadcrumb trail. Styling and Integration: Ensure the custom breadcrumb aligns with the site's styling guidelines and

  integrates seamlessly with the existing site structure.

• Question 34:

  A developer is working on a section of a new content component that has an identical look and behavior to a section of another component within the project's codebase.

  According to AEM Best Practices, how should this component be configured?

  A. The new component should extend an existing component
  B. The old component should be divided into separate components
  C. The new component should be built separately
  D. The existing component should be duplicated
  A. The new component should extend an existing component

  ---

  Explanation/Reference:

  Understanding AEM Best Practices: Extending existing components rather than duplicating code is a best practice in AEM. It promotes code reuse, maintainability, and reduces redundancy.

  Component Extension:

  Definition: Extending a component means creating a new component that inherits functionality and styling from an existing component. This allows for modifications and enhancements without duplicating code. Benefits: This approach

  leverages the existing codebase, ensuring consistency and reducing maintenance efforts. Changes to the base component propagate to the extended component, making updates easier.

  Implementation Steps:

  Identify the Existing Component: Determine the component that has the desired look and behavior.

  Create a New Component: In the AEM component structure, create a new component and specify the existing component as itssling:resourceSuperType.

  Customize as Needed: Add or override properties, scripts, or styles in the new component as needed.

  Example Configuration:

  xmlns:sling="http://sling.apache.org/jcr/sling/1.0" xmlns:cq="http://www.day.com/jcr/cq/1.0"

  sling:resourceType="project/components/content/newComponent" sling:resourceSuperType="project/components/content/existingComponent">
