Adobe Adobe Experience Manager AD0-E134 Questions & Answers

• Question 1:

  In an AEM as a Cloud Service environment, which repository areas are considered as immutable?

  A. /content and /libs

  B. /content and /etc

  C. /apps and /libs

  D. /apps and /content

  Correct Answer: C

  Explanation: In AEM as a Cloud Service environment, the repository areas /apps and /libs are considered as immutable, meaning that they cannot be modified at runtime by any means. These areas contain application code and configuration

  that are deployed via Cloud Manager and are read-only for security and performance reasons. Any changes to these areas require a new deployment via Cloud Manager.

• Question 2:

  A developer needs to create a runmode-specific OSGi configuration for an AEM as a Cloud Service implementation. In which location should the OSGi configuration be created?

  A. core project, (/core/.../config ) folder

• Question 3:

  An AEM application development team is assigned a task to create an Event-Driven Data Layer implementation for an Analytics solution. Which Adobe recommended best practice should the developer choose?

  A. Use Adobe Experience Platform's data layer to integrate with AEM.

  B. Create a custom data layer and add each component template, and its properties to the data layer

  C. Use Adobe Client Data Layer and integrate with Core components.

  D. Create an Adobe Cloud Service configuration to use third-party tool's data layer.

  Correct Answer: C

  Adobe Client Data Layer is a JavaScript library that provides a standardized way to collect, structure, and manage data on a web page. It can be used to implement an event-driven data layer for analytics solutions. It integrates with Core components and allows authors to configure data layer properties for each component. It also supports custom events and data sources.

• Question 4:

  A developer needs to create a dynamic participant step where the participant is selected automatically at run time.

  The developer decides to develop an OSGi service, which needs to implement the com.day.cq.workflow.exec.ParticipantStepChooser interface.

  Which method should the developer implement from the com.day.cq.workflow.exec.ParticipantStepChooser interface?

  A. String getParticipant(Workltem workltem, WorkflowSession workflowSession, MetaDataMap metaDataMap)

  B. void getParticipant(Workltem workltem, WorkflowSession workflowSession, MetaDataMap metaDataMap)

  C. String getDynamicParticipant(Workltem workltem, WorkflowSession workflowSession, MetaDataMap metaDataMap)

  D. void getDynamicParticipant(Workltem workltem, WorkflowSession workflowSession, MetaDataMap metaDataMap)

  Correct Answer: A

• Question 5:

  An AEM server is overloaded with too many concurrently running workflows. The developer decides to reduce the number of concurrent workflows. What should be configured to reduce the number of concurrent workflows?

  A. The number of threads in Scheduler

  B. The number of threads in Apache Felix Jetty Http Service

  C. Launchers for each workflow

  D. Maximum Parallel Jobs in OSGI console

  Correct Answer: D

  Explanation: Maximum Parallel Jobs is a configuration property that controls how many workflows can run concurrently on an AEM instance. Reducing this value can help to avoid overloading the server with too many workflows. Reference: Workflow Engine Configuration section

• Question 6:

  Refer to the exhibit.

  

  The current page has three children.

  What is the final rendered html output for the code snippet?

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: D

• Question 7:

  A customer who is running an AEM application on premise reports that the application is slowing down over time and even crashes The issues seem to start occurring after a new production deployment. The AEM developer knows that the described symptoms could be caused by a memory leak.

  Which two steps should be taken after confirming the problem is related to a memory issue? (Choose two.)

  A. Open the error log and look for messages with 'OutOfMemoryError'

  B. Create a heap dump for analysis

  C. Analyze the request log and make sure the number of requests are below the expected threshold

  D. Increase the cache ratio of the application

  E. Create a thread dump for analysis

  Correct Answer: BE

  Explanation: Creating a heap dump and a thread dump are two steps that should be taken after confirming the problem is related to a memory issue. A heap dump is a snapshot of the memory usage of the Java Virtual Machine (JVM) at a given point in time. A heap dump can be used to identify memory leaks, memory consumption patterns, and objects that occupy large amounts of memory. A thread dump is a snapshot of the state of all threads that are part of the JVM process. A thread dump can be used to identify deadlocks, blocked threads, and CPU-intensive threads.

• Question 8:

  The OSGi configuration is added to a runmode specific configuration "config.author.staging" in AEM as a Cloud Service. The application fails to read the configuration.

  What is a possible cause of this issue?

  A. The custom OSGi configuration runmode used (i.e., "config.author.staging") is not supported in AEM as a Cloud service.

  B. OSGi configuration runmodes cannot be installed automatically on AEM as a Cloud Service. We need to install them as a package using the Package manager.

  C. AEM as a Cloud service does not support OSGi configuration runmodes.

  D. Only specific OSGi configuration runmodes like "config.author" or "config.publish" are supported in AEM as a Cloud service.

  Correct Answer: C

  The correct answer is C: AEM as a Cloud service does not support OSGi configuration runmodes.

  In AEM as a Cloud service, only the default runmodes (i.e., "config.author" and "config.publish") are supported for OSGi configuration. Runmodes like "config.author.staging" are not supported and cannot be added as a Cloud service.

  This is because AEM as a Cloud service has specific limitations and configurations that are imposed by the cloud environment itself. The OSGi configuration runmodes are one such limitation, which can only use the default author and publish runmodes.

• Question 9:

  Which two unit testing dependencies are generated by AEM archetype? (Select two.)

  A. JUnit

  B. Selenium

  C. PowerMock

  D. Mockito

  E. Hobbes

  Correct Answer: AD

  Explanation: JUnit and Mockito are two unit testing dependencies that are generated by AEM archetype. JUnit is a framework for writing and running unit tests in Java. Mockito is a framework for creating and using mock objects in unit tests.

  AEM archetype also adds Apache Sling Mocks and AEM Mocks Test Framework by io.wcm as dependencies for unit testing.

• Question 10:

  A client is having issues with some query results:

  Many of the client's industry terms have the same meaning, and users do not always search the exact wording Many users search by typing in short phrases instead of exact keywords, ex://";cats and dogs"

  What index analyzers should the AEM developer recommend?

  A. 1. Add a Mapping filter to the current indexes

  2. Add a Stop filter to the current indexes

  B. 1. Tokenize the current indexes with a Keyword tokenizer

  2. Add a Mapping filter to the current indexes

  C. 1. Add a Synonym filter to the current indexes

  2. Add a Stop filter to the current indexes

  D. 1. Add a Synonym filter to the current indexes

  2. Add a LowerCase filter to the current indexes

  Correct Answer: D

  A Synonym filter can help to map different terms that have the same meaning, such as "cat" and "feline". A LowerCase filter can help to normalize the case of the terms, so that "cats and dogs" and "Cats and Dogs" are treated the same. Reference: 1 Lucene Analyzers section
