Question 1
Which attribute must be present in all filter rules in AEM dispatcher configuration?
Question 2
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?
Answer : D
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.
Question 3
An AEM application requires LDAP Service integration to synchronize users/groups. Which two OSGi configuration are required for LDAP integration in AEM? (Select Two.)
Question 4
A customer is having trouble with some search queries and provides the following information:
* The logs show the following warning occurs many time: WARN* Traversed 1000 nodes with filter Filter (query=select...)
* The client has more than 100,000 stored in their AEM instance
* The client uses a custom page property to help search for pages of a given type
What should the AEM Developer do to help resolve the client's issue?
Answer : A
The warning WARN* Traversed 1000 nodes with filter Filter (query=select...) indicates that the query is performing a traversal instead of using an index. This results in poor performance, especially when the client has a large number of nodes (e.g., more than 100,000).
To resolve this issue, you should create a custom Oak index for the custom page property. This ensures that the queries can leverage the index for efficient data retrieval.
Steps to create a custom Oak index:
Define the Oak Index:
Navigate to the /oak:index node in CRXDE Lite (http://localhost:4502/crx/de).
Create a new node of type oak:QueryIndexDefinition.
Configure the Index:
Set the properties of the new index node to define the indexing rules for the custom page property.
{
'jcr:primaryType': 'oak:QueryIndexDefinition',
'type': 'property',
'propertyNames': ['customPageProperty'],
'reindex': true,
'async': 'async'
}
Deploy and Reindex:
Save the changes and initiate a reindexing process.
Ensure that the reindex flag is set to true for the newly created index.
Validate the Index:
Use the Index Manager or the AEM Web Console to validate that the new index is enabled and functioning correctly.
By creating a custom Oak index for the custom page property, the queries will be optimized to use the index, significantly improving the search performance and resolving the client's issue.
Question 5
A development team is starting a new AEM project that is going to integrate with the Adobe Commerce platform. The developer needs to create a new AEM project using the Maven command line interface.
How can the 'mvn -B archetype:generate' command help the developer with the integration between AEM and Adobe Commerce?
Question 6
A client has asked to share an HTML version of test coverage report for the AEM project.
What plugin should the AEM developer use to generate test coverage report using latest archetype?
A)
B)
C)
Answer : A
To generate a test coverage report for an AEM project using the latest archetype, the correct plugin to use is the maven-surefire-plugin (Option A). The maven-surefire-plugin is a part of the Maven ecosystem and is widely used to run unit tests within a Maven project. This plugin can be configured to generate detailed test reports, including HTML versions, which can be easily shared with clients.
Here's how to configure the maven-surefire-plugin to generate test coverage reports:
Add the Plugin to the POM File: Add the maven-surefire-plugin configuration in your pom.xml file:
<groupId>org.apache.maven.plugins</groupId>
<version>2.22.2</version>
<configuration>
<reportsDirectory>${project.build.directory}/surefire-reports</reportsDirectory>
<reportFormat>html</reportFormat>
<trimStackTrace>false</trimStackTrace>
</configuration>
Execute the Maven Command: Run the following command to execute the tests and generate the coverage report:
mvn clean test
Locate the Report: The HTML test coverage report will be generated in the target/surefire-reports directory of your project.
