AD0-E123 Adobe Experience Manager Sites Developer Professional Questions and Answers

AEM service pack release notes typically include information that helps users understand the changes that the service pack will bring to their AEM instance. These release notes commonly include:

A. Deprecated features - This section informs users about the features that are being deprecated with the current release and guides them on migrating away from deprecated features to the recommended alternatives.

B. Known issues - This section provides information about any issues or bugs that are known at the time of the release, which might not yet be fixed. It often includes workarounds for these issues if they are available.

• Option C, "Next service pack release date," is not typically included because release dates are subject to change and are usually communicated through official channels closer to the actual release.
• Option D, "Download link to AEM jar," is not included in the release notes but is typically available through the Adobe Software Distribution site or Cloud Manager for AEM as a Cloud Service.

When modifications are made to a workflow model in AEM, they must be saved and synchronized with the running instance of AEM. If a user starts a workflow and does not see the recent changes or workflow steps, it could be because the workflow model was not synced in runtime. This means the running instance of AEM is not yet aware of the changes, and as a result, the workflow instance uses the old version of the workflow model.

• Option B is incorrect because permissions would not cause the recent changes to be unavailable; they would more likely prevent the user from starting the workflow at all.
• Option C is also incorrect because while errors in subsequent steps could potentially stop the workflow from proceeding, they would not prevent new steps from appearing in the workflow instance if they were properly saved and synced.

The "Multi Resource Support" property is used in custom workflow models in AEM to allow a single workflow instance to handle multiple resources, such as assets or pages. When this property is set to true, if multiple assets or pages are selected and theworkflow is initiated, AEM will start only one workflow instance instead of individual instances for each item. This is useful for bulk processing of resources, improving efficiency, and managing workflows better.

• Option B, "Multi Resource Enable," is not a standard AEM workflow property.
• Option C, "Transient Workflow," refers to workflows that do not persist their data and are not related to handling multiple resources in a single instance.

When defining a blueprint configuration in AEM, the content author must adhere to certain structure rules to ensure the proper functioning of the live copy mechanism. The rules include:

B. The immediate child pages of the root are language branches of the website - This structure is commonly used in AEM to organize content according to language and regional variations, allowing for more manageable and scalable content management across different locales.

D. The website should have a single page as the root - Having a single root page for a website is a standard practice in AEM as it simplifies the content hierarchy and providesa clear entry point for the site structure. This root page then serves as the source for live copies.

Options A and C are not strict requirements for a blueprint configuration. AEM does not mandate that the root of each language branch has at least two child pages or that each language page must have a country child page. These decisions are usually based on the specific content structure and organizational needs of the website.

In an AEM Single Page Application (SPA) project, the.model.jsonendpoint is used to expose the properties of a Sling Model as JSON. This is useful for SPAs that need to access component properties dynamically. The front-end developer should check the URL[homepage-path]/model.jsonto see the JSON output of the Sling Model for the new component. This endpoint provides a tree of the page content as JSON, which includes the Sling Model's exported properties for components included on the page.

AEM as a Cloud Service includes the latest AEM features out-of-the-box, including AEM Core Components, which are production-ready without the need for additional downloads or installations of sample content. This version of AEM has a continuousdelivery model, ensuring that the most up-to-date features and components are readily available.

• Option A, Version 6.3, is incorrect because this version would require the manual download and installation of core components.
• Option B, Adobe Managed Services, is not a version of AEM, but rather a hosting option that could include various versions of AEM.

In AEM, Lucene is often used for indexing due to its powerful full-text search capabilities, and it also supports asynchronous indexing. Asynchronous indexing allows the system to handle other tasks while indexing is being processed in the background, which can improve performance and scalability. This is especially useful when multiple properties need to be indexed without impacting the immediate response times of the system. Therefore, when a developer needs to enable the indexing of multiple properties asynchronously, a Lucene index is the most suitable choice.

In HTL (HTML Template Language), the syntax to manipulate the URI path does not provide direct methods for removing selectors. However, within Sling and HTL, the Link Handler can be extended to support such operations. For out-of-the-box HTL, the proper approach to manipulate the link would be done in the Java layer (e.g., a Sling Model or a Use-Class in HTL), and then passed to the template for rendering. Nevertheless, if such a functionality were to be implemented within HTL, it would require custom code and not use the indicated syntax options. It is important to note that options A and B with 'removeSelectors' are not standard HTL syntax.

When an AEM instance starts with specified run modes, it selects configurations from the repository that match those run modes. Run modes allow for flexible management of settings and configurations across different environments. For the instance started with 'author', 'dev', and 'emea' run modes, it would apply configurations from paths that match these run modes.

Option B,/config/author.dev.emea.noldap, is correct. This path matches all three run modes specified and would, therefore, be included.

Option D,/apps/mysite/config.author.emea.dev, is also correct. This path matches the run modes and would be applied to the instance as well.

Options A and C do not match all three run modes and therefore would not be applied.

When the 'Display Mode' is set to 'Single Text Element' in the configuration of a Content Fragment Component in AEM, the properties that will determine the resulting action are related to how the text is displayed and managed in terms of paragraphs.

• C. Paragraph Range — This property would determine the range of paragraphs to display from the multiline text element.
• D. Paragraph Scope — This property would define the scope of the paragraph, such as whether all paragraphs are included or just a specific subset.

Options A (Paragraph Description) and B (Paragraph Heading) are not directly related to the action of displaying a single text element with paragraph control.

In HTL, theformatoption in the data-sly-use or data-sly-test attribute can be used to format values according to a pattern. The pattern'-#.##%'indicates that the number should be formatted as a percentage with up to two decimal places. ThepiValuevariable would be the number to format, and in this example, it would convert -3.14 to -314%. The@symbol is used to denote the use of an option with the variable in HTL.

• Options B and C are incorrect because they do not use the correct syntax for the format option in HTL. The use of@is to specify options and not part of the variable or pattern itself.

Global project properties in a Maven project are typically defined in the<properties>section of the parentpom.xmlfile. This allows these properties to be shared across all modules of the project, ensuring consistency and easy maintenance of project-wide settings such as versions of dependencies, plugin configurations, and other properties that are common across multiple modules of the project.
