Pass the Adobe Experience Manager AD0-E123 Questions and answers with ValidTests

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.

To start an AEM instance in debug mode automatically, without manually providing JVM parameters each time, a developer can add the required JVM parameters to the AEM instance's start script. This script is executed every time the AEM instance is started, and by including the debug parameters there, the instance will automatically start in debug mode each time. The start script is typically namedstart.bat(for Windows) orstart.sh(for Unix-based systems) and is located in the AEM installation directory.

Adding JVM parameters to a properties file under a run mode-specific directory (Option A) or setting an OSGi configuration (Option B) are not standard methods for configuring JVM debug parameters for AEM startup.

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.

When using a Network File System (NFS) for AEM,CachingFileDataStoreis recommended because it caches binary data on the file system and stores only references to the binaries in the repository. This can be beneficial for performance, as it reduces the latency associated with reading binaries over the network, especially when NFS is being used. The caching layer helps in optimizing read operations by keeping a local cache of frequently accessed data.

S3DataStoreis used when integrating with Amazon S3 for storage.

FileDataStoredoes not provide caching capabilities and would not be as efficient asCachingFileDataStorewhen using NFS.

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.

Experience Fragments in AEM can be exported to Adobe Target, and the default format for this export is HTML. When Experience Fragments are exported to Adobe Target, they are typically used for personalization and A/B testing. HTML is the format that is readily usable within Adobe Target to create variations of a page or a component for these testing purposes.

XML (Option B) and JSON (Option C) are not the default formats for exporting Experience Fragments to Adobe Target. While they can represent structured data, for the purposes of visual personalization in Adobe Target, the HTML format is used because it can directly represent the markup required for the content to be rendered in a browser.

In Maven, themaven-clean-pluginis used to clean the project by removing files generated at build-time in thetargetdirectory. Before a new build, cleaning the project is a common practice to ensure that no stale artifacts affect the new build. The plugin's goalcleanis bound to the clean phase of the build lifecycle and can be executed with the commandmvn clean.

Option A,mvn-clean-plugin, is incorrectly named; the correct name ismaven-clean-plugin.

Option B,maven-scr-plugin, is related to Service Component Runtime and not to cleaning build artifacts.

Given the dispatcher configuration snippet provided in the image, we can understand the URL patterns that will be ignored (not cached) by the dispatcher. The configuration under/ignoreUrlParamsshows patterns to match query parameters in the URLs:

/0001 { /glob "*" /type "deny" } means that by default, all query parameters are ignored (not cached).

/0002 { /glob "search" /type "allow" } specifically allows caching for URLs with the 'search' parameter.

/0003 { /glob "order" /type "allow" } specifically allows caching for URLs with the 'order' parameter.

Based on this, let's evaluate the options:

A. /myproduct/myrecipe.html?search=searchparam — This URL will not be cached because the 'search' parameter is allowed, but the actual value 'searchparam' does not match any allow pattern. B. /myproduct/myrecipe.html?search=s&order=asc&brand=ad — This URL will not be cached because although 'search' and 'order' parameters are allowed, the 'brand' parameter is not allowed according to the configuration. C./myproduct/myrecipe.html?brand=mybrand — This URL will be cached because there are no allowed parameters, so the default deny does not apply, and the page can be cached without considering the 'brand' parameter.

Therefore, the page that will be cached on the dispatcher is the one in option C, as it does not contain any of the explicitly allowed query parameters ('search' or 'order'), and all other parameters are ignored by default.

When customizing a core component in AEM, setting thesling:resourceSuperTypeproperty in the new component's definition allows it to inherit features from an existing core component. This property points to the resource type of the core component that is being extended or customized. By doing so, the new component inherits the core component's logic and rendering scripts but can be customized further according to project-specific requirements.

Option A,sling:resourceType, is used to define the primary resource type for a component and does not indicate inheritance.

Option B,jcr:title, is used to give a human-readable title to a node in the JCR and is unrelated to component inheritance.

Updating the cache in AEM is critical to ensure that users receive the most current content without unnecessary delays. Two common methods used to update the cache include:

A. Content Updates - Content updates can trigger an invalidation or flush of the cache. When content is published or updated on the AEM author instance and replicated to the publish instance, the dispatcher cache can be set to automatically invalidate the affected pages. This ensures that the next request to these pages serves the latest content.

D. Auto-invalidation on the Dispatcher - The dispatcher can be configured to automatically invalidate cached content under certain conditions, such as when a TTL (Time To Live) expires or when specific actions occur, such as a page activation ordeactivation. This is often preferred to manual cache clearing as it can be more efficient and targeted to the specific content that has changed.

Options B and C are incorrect because restarting the AEM Author or Publish instances does not directly relate to cache update methods. These actions are more associated with system maintenance or updates and would not be standard practice for updating cached content.
