• Question 32:

  A new component called Page Headline needs to be implemented. The only difference from the Title component delivered by Adobe's WCM Core Components is that the text needs to be taken from the current page title instead of jcr:title.

  How should a developer implement this request?

  A. 1. Create custom component 2. Implement Sling Modal as follows: @Model(adaptables = SlingHttpServletRequest.class, adapters = Title.class, resourceType = "myproject/components/pageHeadline") public class PageHeadline { @ScriptVariable private Page currentPage; @Override public String getText() { return currentPage.getTitle(); } }
  B. 1. Create proxy component from the core Title component 2. Implement Sling Model as follows: @Model(adaptables = Resource.class, adapters = Title.class, resourceType = "myproject/components/pageHeadline") public class PageHeadline implements Title { @ScriptVariable private Page currentPage; @Self @Via(type = ResourceSuperType.class) private Title title; @Override public String getText() { return currentPage.getTitle(); } }
  C. 1. Create proxy component from the core Title component 2. Implement Sling Model as follows: @Model(adaptables = SlingHttpServletRequest.class, adapters = Title.class, resourceType = "myproject/components/pageHeadline") public class PageHeadline implements Title { @ScriptVariable private Page currentPage; @Self @Via(type = ResourceSuperType.class) private Title title; @Override public String getText() { return currentPage.getTitle(); } @Override public String getType() { return title.getType(); } }
  C. 1. Create proxy component from the core Title component 2. Implement Sling Model as follows: @Model(adaptables = SlingHttpServletRequest.class, adapters = Title.class, resourceType = "myproject/components/pageHeadline") public class PageHeadline implements Title { @ScriptVariable private Page currentPage; @Self @Via(type = ResourceSuperType.class) private Title title; @Override public String getText() { return currentPage.getTitle(); } @Override public String getType() { return title.getType(); } }

• Question 33:

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

  ---

  Explanation Explanation/Reference: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 34:

  An AEM Developer needs to build out a project that contains only the required modules. Which most recent AEM Archetype module is optional?

  A. it.launcher
  B. ui.frontend
  C. ui.tests
  D. ui.content
  C. ui.tests

• Question 35:

  AMS recommends a learner to upgrade AEM servers with In-place Upgrade because the existing version has reached EOL.

  What are two disadvantages of performing an In-place Upgrade to the latest version of AEM? (Select two.)

  A. Content revision history is not preserved.
  B. Depending on the version difference between the old and new instances, the upgrade can be a long and arduous process.
  C. Content migration is required.
  D. ACLs, users, and groups are lost.
  E. Complex developer setup and automation of the upgrade process.
  B. Depending on the version difference between the old and new instances, the upgrade can be a long and arduous process.
  E. Complex developer setup and automation of the upgrade process.

• Question 36:

  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
  B. Create a heap dump for analysis
  E. Create a thread dump for analysis

  ---

  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 37:

  A developer is working on a project based on core components. The client requests that text pasted inside the Text component should be stripped of all styling and formatting.

  The developer needs to override RTE plugin implementation and change the default paste (CTRL+V) behavior.

  Which paste option should the developer add to achieve this?

  A. defaultPasteMode=text
  B. defaultPasteMode=plaintext
  C. pasleMode=text
  D. pasteMode-plaintext
  B. defaultPasteMode=plaintext

• Question 38:

  A developer has multiple LDAP Authentication providers. The user is not required to pass the authentication test of every Authentication provider. If authentication succeeds, control is returned to the caller; no subsequent Authentication

  provider down the list is executed.

  If authentication fails, authentication continues down the list of providers.

  What should be the JAAS Control flag value in Apache Jackrabbit Oak External Login Module configuration?

  A. SUFFICIENT
  B. REQUIRED
  C. MANDATORY
  D. OPTIONAL
  A. SUFFICIENT

• Question 39:

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

  ---

  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 40:

  An AEM application requires LDAP Service integration to synchronize users/groups. Which two OSGi configuration are required for LDAP integration in AEM? (Select Two.)

  A. Apache Jackrabbit Oak AuthorizableActionProvider
  B. Apache Jackrabbit Oak Solr server provider
  C. Apache Jackrabbit Oak CUG Configuration
  D. Apache Jackrabbit Oak External Login Module
  E. Apache Jackrabbit Oak Default Sync Handler
  D. Apache Jackrabbit Oak External Login Module
  E. Apache Jackrabbit Oak Default Sync Handler

  ---

  The Apache Jackrabbit Oak External Login Module and Apache Jackrabbit Oak Default Sync Handler are the two OSGi configurations that are required for LDAP integration in AEM. The External Login Module defines how AEM connects to the LDAP server and authenticates users against it. The Default Sync Handler defines how AEM synchronizes users and groups from the LDAP server to the repository.
