Adobe Adobe Certifications AD0-E134 Questions & Answers

• Question 21:

  If multiple configurations for the same PID are applicable, which configuration is applied?

  A. The last modified configuration is applied.

  B. The configuration with the highest number of matching run modes is applied.

  C. The one that occurs first in the repository is applied.

  D. A configuration factory is created and all configurations are applied.

  Correct Answer: B

  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.

• Question 22:

  Which AEM as a Cloud Service role can configure or run pipelines?

  A. Deployment Manager

  B. DevOps

  C. Developer

  D. Program Manager

  Correct Answer: A

  Explanation: The Deployment Manager is a role that can configure or run pipelines in Cloud Manager. The Deployment Manager can create and edit programs and environments, configure pipelines, start and cancel pipeline executions, and

  approve or reject deployments to production. The Deployment Manager role requires an IMS ID that is associated with the Adobe Experience Cloud product profile.

• Question 23:

  Which tool should a developer use to look up Adobe Identity Management System (IMS) users by email and return their IMS IDs?

  A. Developer Console

  C. IMS Lookup Tool

  D. Cloud Acceleration

  Correct Answer: C

  Explanation: The IMS Lookup Tool is a tool that allows looking up Adobe Identity Management System (IMS) users by email and returning their IMS IDs. The IMS Lookup Tool is available in the Cloud Manager UI under the Tools menu. The

  IMS Lookup Tool can be used to find the IMS IDs of users who need to be added to Cloud Manager programs or environments.

• Question 24:

  On package install content that is already present in the repos must not be overwritten and if not present in the repos it must not be removed.

  Which import mode should the developer use?

  A. update

  B. replace

  C. merge

  Correct Answer: C

• Question 25:

  A customer adds third-party client libraries to add some features in an existing AEM application, which will significantly reduce performance.

  How should the developer optimize the site?

  A. Embed client libraries to consolidate them into fewer files.

  B. Debug third-party client lib and fix the code.

  C. Rebuild Client libraries.

  Correct Answer: A

  Explanation: Embedding client libraries is a technique that allows combining code from multiple client libraries into a single file. This reduces the number of network requests and improves performance. Embedding client libraries can be done

  by using the embed property of the cq:ClientLibraryFolder node and specifying the categories of the client libraries to be embedded.

• Question 27:

  An AEM Developer receives requirements for Sling Models in a human-readable yaml format. A custom application needs to be built. The dependency is as shown:

  

  A. 1. Create OSGI models to export as yaml

  2. Configure mime type in Apache Sling MIME Type Service

  B. 1. Create OSGI models to export as yaml

  2. Configure mime type in Apache Sling Servlet/Script Resolver and Error Handler

  C. 1. Create Sling models to export as yaml

  2. Configure mime type in Apache Sling MIME Type Service

  D. 1. Create Sling models to export as yaml

  2. Configure mime type in Apache Sling Referrer Filter

  Correct Answer: C

  Explanation: To create Sling Models that can export data in a human-readable yaml format, the following steps are required: Create Sling models to export as yaml. Sling models are Java classes that can be used to represent resources in AEM. Sling models can use annotations to define how they can be adapted from a resource and how they can export data in different formats. To export data in yaml format, the Sling model class needs to use the @Model annotation with the resourceType parameter set to the resource type of the resource that the model represents. The Sling model class also needs to implement the org.apache.sling.models.annotations.Exporter annotation with the name parameter set to "jackson" and the extensions parameter set to "yaml". The Sling model class also needs to use the @JsonProperty annotation on the fields or methods that need to be exported in yaml format. Configure mime type in Apache Sling MIME Type Service. The Apache Sling MIME Type Service is an OSGi service that maps file extensions to MIME types and vice versa. To enable the yaml format for Sling models, the MIME Type Service needs to be configured with a new entry for the yaml extension and its corresponding MIME type, which is "application/x-yaml". This can be done by creating an OSGi configuration for the org.apache.sling.commons.mime.internal.MimeTypeServiceImpl service and adding the entry "yaml=application/x-yaml" to the mime.types property.

• Question 28:

  A snippet throws an exception at runtime:

  @Model(adaptables = {Resource.class}) public class MyCustomModel {

  (SSIingObject

  private Resource resource;

  

  What should the developer add to fix it?

  A. defaultlnjectionStrategy = DefaultlnjectionStrategy property to @Model Class annotation

  B. (㎡ptional annotation to page field

  C. throws Exception at the end of the init method declaration

  D. SlingHttpServletRequest.class to adaptables property of ㎝odel Class annotation

  Correct Answer: A

  The developer should add the defaultInjectionStrategy = DefaultInjectionStrategy property to the @Model Class annotation to fix the snippet. The defaultInjectionStrategy property defines how the Sling Model handles missing or null values for the injected fields. By default, the Sling Model uses the REQUIRED injection strategy, which means that all fields must have a non-null value or else an exception is thrown. By setting the defaultInjectionStrategy property to OPTIONAL, the Sling Model allows null values for the injected fields and does not throw an exception. This way, if the page field is null because the resource is not a page, the Sling Model can still work without errors.

• Question 29:

  Which AEM dependency provides APIs for all AEM environments?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: D

• Question 30:

  A developer needs to create a workflow custom process step in AEM. In a custom process step, an OSGi component needs to implement the WorkflowProcess interface. Which method should the developer implement?

  A. call

  B. apply

  C. execute

  D. submit

  Correct Answer: C

  Explanation: The WorkflowProcess interface is the interface to be used for automatic workflow steps implemented in Java. Classes implementing this interface define Java based processes that can be attached to a WorkflowNode and executed by the workflow engine. The method execute takes a WorkItem, a WorkflowSession and a MetaDataMap as parameters and performs the logic of the custom process step.
