Most Recent Adobe AD0-E123 Exam Questions & 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.

In AEM, OSGi configurations are typically managed within the ui.apps Maven module. This module is responsible for the application code that comprises the components, templates, and OSGi configurations among other things. By placing OSGi configurations within the ui.apps module, a developer can ensure that these configurations are deployed to the JCR repository and become part of the application package.

When using a Network File System (NFS) for AEM, CachingFileDataStore is 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.

S3DataStore is used when integrating with Amazon S3 for storage.

FileDataStore does not provide caching capabilities and would not be as efficient as CachingFileDataStore when using NFS.

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 Sling Models, annotations are used to map request parameters, attributes, and properties to fields in Java classes. When an HTL script passes parameters to a Sling Model, the Sling Model can use annotations to access these parameters.

Option B uses the @RequestAttribute annotation which allows the Sling Model to retrieve an attribute that has been set on the Sling HTTP request object. This is a valid approach to read the 'testParam' if it has been set as a request attribute.

Option C uses the @Inject annotation with the name attribute specifying the name of the parameter to inject. This is another valid approach to read the 'testParam' from the request.

Option A is incorrect because @Named is not the correct annotation for retrieving request attributes or parameters.

Option D is incorrect because there is no @Prop annotation in Sling Models; it's likely confused with the @Property annotation which is not the correct one for this context either.
