NEW QUESTION # 42
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 Synonym filter to the current indexes
2. Add a Stop filter to the current indexes - B. 1. Add a Mapping filter to the current indexes
2. Add a Stop filter to the current indexes - C. 1. Add a Synonym filter to the current indexes
2. Add a LowerCase filter to the current indexes - D. 1. Tokenize the current indexes with a Keyword tokenizer
2. Add a Mapping filter to the current indexes
Answer: C
Explanation:
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.
NEW QUESTION # 43
Refer to the exhibit.
The current page has three children.
What is the final rendered html output for the code snippet?
- A.
- B.
- C.
Answer: B
Explanation:
Explanation
Option B is the final rendered html output for the code snippet. The code snippet uses the data-sly-list block statement to iterate over the child pages of the current page. The data-sly-list statement assigns each child page to a variable named page and provides an index variable named i. The code snippet then uses the data-sly-test block statement to check if the index is odd or even and applies a different CSS class accordingly. The code snippet also uses the data-sly-element block statement to create an HTML element with the name specified by the elementName variable. The code snippet also uses the data-sly-attribute block statement to add an attribute with the name specified by the attrName variable and the value specified by the attrValue variable. The code snippet also uses the data-sly-resource block statement to include a resource with the path specified by the page.path variable and the resourceType specified by the resourceType variable.

NEW QUESTION # 44
In a non-optimized website, the final HTML generated for a typical page by publish instance includes a relatively large number of <script> elements that refer to other script files loaded from AEM environment. The developer wants to minimize these network calls by combining all required client library code into a single file to reduce the number of back-and-forth requests on page load.
Which step should a developer take to solve this issue?
- A. Embed the required libraries into an app-specific client library using the dependencies property of the cq:Clientl_ibraryFolder node
- B. Embed the required libraries into an app-specific client library using the embed property of the cq:ClientLibraryFolder node
- C. Embed the required libraries into an app-specific client library using the allowProxy property of the cq:Clientl_ibraryFolder node
- D. Add the categories property of the cq:Clientl_ibraryFolder node into an app-specific client library folder
Answer: A
Explanation:
The embed property of the cq:ClientLibraryFolder node allows embedding code from a client library into another client library. At runtime, the generated JS and CSS files of the embedding library include the code of the embedded library. This reduces the number of network calls and improves performance. Embedding code is useful for providing access to libraries that are stored in secured areas of the repository. References:

NEW QUESTION # 45
Which configuration/section should be used to resolve the domain name by dispatcher?
- A. Configuration in filters.any
- B. Configuration in DNS
- C. Configuration in httpd.conf
- D. Configuration in vhosts file
Answer: B
Explanation:
Explanation
The configuration in DNS (Domain Name System) should be used to resolve the domain name by dispatcher.
The DNS resolves the domain names to the IP address of the web server that hosts the dispatcher. The dispatcher then matches the incoming request URL with the cached files or the AEM publish instances.

NEW QUESTION # 47
A developer needs to create sling models for two fields name and occupations. The dialog has two fields, name - a single value field, and occupations - a multi value field.
The following code is included in sling models inherited from interface com.adobe.aem.guides.wknd.core.models.Byline
Which method should be used to used to represent this model in HTL?
- A.
- B.
- C.
- D.
Answer: C
Explanation:
Option C is the correct implementation for the Sling Model. Option C uses the @Model annotation with the adaptables parameter set to Resource.class. This allows the Sling Model to adapt from a resource object and access its properties using the ValueMap interface. Option C also uses the @Inject annotation with the name parameter set to "./name" and "./occupations" to inject the values of the name and occupations properties into the name and occupations fields. Option C also uses the @Named annotation with the value parameter set to
"byline" to specify the name of the Sling Model that can be used in HTL scripts. References:

NEW QUESTION # 48
An AEM developer is assigned a task to design a workflow. The workflow is supposed to collect data from the participant and then determine the reviewer/approver branch to proceed further.
Which workflow step should be used by the developer?
- A. Dialog Participant Step
- B. Dynamic Participant Step
- C. Form Participant Step
- D. Workflow Initiator Participant Chooser
Answer: B
Explanation:
To design a workflow that collects data from the participant and then determines the reviewer/approver branch to proceed further, the developer should use theDynamic Participant Step. This workflow step allows for dynamic determination of participants based on the data collected or any other logic implemented in the workflow.
Here's how to implement a Dynamic Participant Step in AEM:
* Create the Workflow Model:
* In AEM, navigate to Tools > Workflow > Models.
* Create a new workflow model or edit an existing one.
* Add Dynamic Participant Step:
* Drag and drop the Dynamic Participant Step into your workflow model.
* Configure the Dynamic Participant Step:
* Click on the Dynamic Participant Step and configure it by specifying the participant chooser class.
This class should implement the logic to determine the next participant.
@Component(service = ParticipantStepChooser.class, property = {
"service.description=Dynamic Participant Chooser"
})
public class CustomParticipantStepChooser implements ParticipantStepChooser {
@Override
public String getParticipant(WorkItem workItem, WorkflowSession workflowSession, MetaDataMap metaDataMap) {
// Custom logic to determine the participant based on workflow data
String reviewer = // logic to determine reviewer
return reviewer;
}
}
* Implement Participant Chooser Logic:
* The CustomParticipantStepChooser class should contain the logic to determine the next participant based on the workflow data. This can include reading workflow variables, making decisions based on conditions, or any other custom logic.
* Deploy and Test:
* Save the workflow model and test it by starting a new workflow instance. Ensure that the dynamic participant determination works as expected.
By using the Dynamic Participant Step, you can create flexible workflows that adapt to the data and context, ensuring that the appropriate participants are chosen dynamically.

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 thread dump for analysis
- C. Increase the cache ratio of the application
- D. Create a heap dump for analysis
- E. Analyze the request log and make sure the number of requests are below the expected threshold
Answer: B,D
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. References:

/apps O 2. Modifying a configuration in /apps will take immediate effect
3. Modifying a configuration in the Web console will take immediate effect as it takes precedence at runtime.
Answer: A
Explanation:
The order of resolution for OSGi configurations at runtime in AEM is as follows:
* Web Console Configuration:
* Changes made through the OSGi Web Console take immediate effect and have the highest precedence. This is because these configurations are considered the most direct way to adjust OSGi settings at runtime.
* References:OSGi Configuration in AEM
* /apps Configuration:
* Configurations in the /apps directory take precedence over those in the /libs directory. This allows custom configurations to override the default configurations provided by AEM.
* References:AEM Project Structure
* /libs Configuration:
* Configurations in the /libs directory are the default configurations provided by AEM. They are overridden by any configurations in the /apps directory.
* References:AEM Configuration
By understanding this order, developers can effectively manage and prioritize their OSGi configurations to ensure the desired behavior of their AEM instances.
