NEW QUESTION # 33
A new component called Page Headline needs to be implemented. The only difference to 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
B)
1. Create proxy component from the core title component
2. Implement sling Model as follows
C)
1. Create proxy component from the core title component
2. Implement Sling Model as follows
- A. Option A
- B. Option C
- C. Option B
Answer: B
Explanation:
To implement a new component called "Page Headline" which takes the text from the current page title instead of jcr:title, you should create a proxy component from the core title component and implement a Sling Model accordingly. Option C demonstrates the correct approach to achieve this functionality.
Here is a detailed explanation of Option C:
* Create Proxy Component:
* Create a new component in your project that will act as a proxy to the core title component. This involves creating a new component node in the repository that inherits from the core title component.
* Example path: /apps/myproject/components/pageHeadline with sling:resourceSuperType set to core/wcm/components/title/v2/title.
* Implement Sling Model:
* Implement a Sling Model that adapts from SlingHttpServletRequest and Title.class, ensuring it
* overrides the text fetching logic to retrieve the title from the current page's title.
* The model will use @ScriptVariable to inject the current page and @Self to access the core title component's logic.
@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();
}
}
* @Model Annotation: Specifies that this class is a Sling Model and adapts from SlingHttpServletRequest. It is also an adapter for Title.class and applies to the myproject/components/pageHeadline resource type.
* @ScriptVariable: Injects the current Page object, which allows access to the current page's properties.
* @Self @Via(type = ResourceSuperType.class): Injects the core title component, allowing the reuse of existing logic.
* getText() Method: Overrides the getText() method to return the title from the current page instead of the jcr:title.
* getType() Method: Delegates to the core title component's getType() method to maintain existing functionality.
This approach leverages the power of Sling Models and the core components to extend functionality while keeping the implementation clean and maintainable.

- A. Launchers for each workflow
- B. The number of threads in Apache Felix Jetty Http Service
- C. The number of threads in Scheduler
- D. Maximum Parallel Jobs in OSGI console
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.
NEW QUESTION # 35
Which configuration/section should be used to resolve the domain name by dispatcher?
- A. Configuration in vhosts file
- B. Configuration in filters.any
- C. Configuration in DNS
- D. Configuration in httpd.conf
Answer: A
Explanation:
To resolve the domain name by the dispatcher, you should configure it in the vhosts file. The vhosts file is part of the Apache HTTP server configuration and allows you to define how requests for different domain names are handled. This is crucial for setting up virtual hosts, which is essential for resolving domain names and directing them to the appropriate content served by your AEM instance.
Here are the detailed steps to configure domain name resolution in the vhosts file:
* Locate the vhosts file: The file is typically located in the conf directory of your Apache HTTP server installation. Common paths are:
* /etc/httpd/conf/httpd.conf (on many Linux systems)
* /usr/local/apache2/conf/httpd.conf (if installed from source)
* Edit the vhosts file: Open the file with a text editor. You might need superuser permissions to edit this file.
* Add a VirtualHost directive: Define a new VirtualHost block for your domain. For example:
<VirtualHost *:80>
ServerName www.example.com
ServerAlias example.com
DocumentRoot "/path/to/your/document/root"
# Dispatcher configuration
<IfModule disp_apache2.c>
SetHandler dispatcher-handler
ModMimeUsePathInfo On
</IfModule>
<Directory "/path/to/your/document/root">
AllowOverride None
Options FollowSymLinks
Require all granted
</Directory>
</VirtualHost>
* ServerName specifies the primary domain name.
* ServerAlias allows you to specify additional names that should resolve to the same content.
* DocumentRoot specifies the directory from which the content should be served.
* The <IfModule disp_apache2.c> section includes the Dispatcher handler configuration.
Restart Apache: After saving the changes to the vhosts file, restart the Apache server to apply the changes.
sudo systemctl restart httpd
# or
sudo service apache2 restart

NEW QUESTION # 36
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. Add the categories property of the cq:Clientl_ibraryFolder node into an app-specific client library folder
- B. Embed the required libraries into an app-specific client library using the allowProxy property of the cq:Clientl_ibraryFolder node
- C. Embed the required libraries into an app-specific client library using the dependencies property of the cq:Clientl_ibraryFolder node
- D. Embed the required libraries into an app-specific client library using the embed property of the cq:ClientLibraryFolder node
Answer: C
Explanation:
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 arestored in secured areas of the repository. References:

- A. maven-enforcer-plugin
- B. femaven-assembly-plugin
- C. content-package-maven-plugin
- D. aemanalyser-maven-plugin
Answer: D
Explanation:
Explanation
The aemanalyser-maven-plugin is a Maven plugin that checks if all the requirements declarations made in OSGi bundles are satisfied by the capabilities declarations of other bundles included in the Maven project.
This plugin ensures that the OSGi bundles are consistent and can be resolved at runtime. The plugin also checks for other issues such as API compatibility, package versioning, and bundle start order. References:

@ObjectClassDefinition(name = "My configuration") - D. @Component(service = ConfigurationFactory.class)
@Designate(ocd = ConfigurationFactorylmpl.Config.class, factory=true)
Answer: D
Explanation:
Explanation
The @Component(service = ConfigurationFactory.class) @Designate(ocd =
ConfigurationFactorylmpl.Config.class,factory=true) option is recommended for creating a multi-tenancy configuration and binding multiple configurations to it. This option uses the OSGi R6 annotations to define a component that provides a service of type ConfigurationFactory and designates a class that contains the configuration properties. The factory=true attribute indicates that multiple configurations can be created for this component.

NEW QUESTION # 39
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 Sling models to export as yaml
2. Configure mime type in Apache Sling MIME Type Service - B. 1. Create Sling models to export as yaml
2. Configure mime type in Apache Sling Referrer Filter - C. 1. Create OSGI models to export as yaml
2. Configure mime type in Apache Sling MIME Type Service - D. 1. Create OSGI models to export as yaml
2. Configure mime type in Apache Sling Servlet/Script Resolver and Error Handler
Answer: A
Explanation:
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.

NEW QUESTION # 41
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: B
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 # 42
A developer is using sling context-aware configuration trying to get the configuration resource using:
This works as intended in author and in publish when logged in lo publish as admin. However this gives a null when run as anonymous. Which method is going to fix the issue?
- A. Applying read permissions to anonymous user for /cont directory
- B. Applying read permissions to anonymous user for /content directory
- C. Applying write permissions to anonymous user for/conf directory.
- D. Applying read permissions to anonymous user for /etc directory.
Answer: B
Explanation:
The issue arises because the anonymous user does not have the necessary read permissions for the /content directory. When using Sling context-aware configurations, access to the configuration resource is required. If the anonymous user lacks read permissions, the configuration cannot be retrieved, resulting in a null value.
To fix this issue, you need to grant read permissions to the anonymous user for the /content directory.
Steps to apply read permissions:
* Access CRXDE Lite:
Log into your AEM instance and navigate to CRXDE Lite (http://localhost:4502/crx/de).
* Navigate to the /content Directory: In the CRXDE Lite interface, browse to the /content directory.
* Set Permissions:
* Right-click on the /content directory and select "Permissions".
* Add the anonymous user (if not already present).
* Grant read permissions to the anonymous user.
* Save Changes: Apply the changes and ensure that they are saved correctly.
* Test the Configuration: Log out of the AEM instance and test the context-aware configuration as an anonymous user to ensure that the configuration resource can now be retrieved.
By granting read permissions to the anonymous user for the /content directory, you allow access to the necessary configuration resources, resolving the issue.

NEW QUESTION # 43
A project requires sharing information between SPA components. What is the least complex approach to achieve that objective?
- A. Centralize the logic and broadcast to the necessary components.
- B. Implement a state library in order to share component states.
- C. Utilize model props to drill down and access or set the state on desired components.
- D. Customize and extend the container component to leverage the object hierarchy.
Answer: C
Explanation:
Utilizing model props to drill down and access or set the state on desired components is the least complex approach for sharing information between Single Page Application (SPA) components in AEM.
Here's why using model props is effective:
* Simplicity: This approach leverages the existing component hierarchy and properties, making it straightforward to pass data between components.
* Direct Access: Model props allow for direct access to the state and properties of parent or sibling components, enabling easy data sharing.
* Minimal Setup: Unlike implementing a state library or customizing container components, using model props requires minimal additional setup, reducing complexity and potential overhead.
Steps to utilize model props for state management:
* Define the State in the Parent Component: Ensure that the parent component maintains the state that needs to be shared.
* Pass Props to Child Components: Pass the necessary state and any setter functions as props to the child components. For example, in a React-based SPA, you can do this using JSX syntax:
function ParentComponent() {
const [sharedState, setSharedState] = useState(initialState);
return (
<ChildComponentA sharedState={sharedState} setSharedState={setSharedState} />
<ChildComponentB sharedState={sharedState} setSharedState={setSharedState} /> );
}
Access and Modify State in Child Components: In the child components, access and modify the shared state using the props passed from the parent:
function ChildComponentA({ sharedState, setSharedState }) {
return (
<div>
{sharedState}
<button onClick={() => setSharedState(newState)}>Update State</button>
</div>
);
}
By using this approach, you ensure a simple and effective way of managing and sharing state across components in your SPA, adhering to best practices for component-based architecture.

NEW QUESTION # 45
A developer is on an AEM application that is being used to calculate an employee's salary. The calculation is done in an OSGi service called CalculationService. This service class has a dependency on one other service, called the EmployeeService.
How should the developer make sure that the critical code in the CalculationService has a high unit test coverage?
- A. Use the feature flag in the unit test to disable the calls to the EmployeeService
- B. Use a mock framework in the unit test to inject the EmployeeService
- C. Instantiate the EmployeeService in the unit test and pass it to the constructor of the CalculationService
- D. Use a mock framework in the unit test to inject the CalculationService
Answer: B
Explanation:
Explanation
A mock framework is a tool that allows creating mock objects that simulate the behavior of real objects in a controlled way. A mock framework can be used in a unit test to inject the EmployeeService dependency into the CalculationService and verify its interactions. This way, the unit test can focus on testing the logic of the CalculationService without relying on the actual implementation of the EmployeeService. References:

NEW QUESTION # 46
A developer has multiple LDAP Authentication providers. The user is not required to pass the authentication test of the 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. MANDATORY
- C. REQUIRED
- D. OPTIONAL
Answer: A
Explanation:
The JAAS Control flag SUFFICIENT is used when you have multiple LDAP authentication providers and you want the following behavior:
* Immediate Return on Success:
* If authentication succeeds with the current provider, control is returned to the caller immediately, and no subsequent providers in the list are executed.
* This is efficient and reduces unnecessary processing if a user's credentials are successfully authenticated by one of the initial providers.
* Continue on Failure:
* If authentication fails with the current provider, the authentication process continues down the list of providers until a successful authentication occurs or all providers are exhausted.
* This ensures that all available providers are tried before authentication is ultimately denied.
The SUFFICIENT control flag is thus well-suited for configurations where multiple authentication providers are used, and only one successful authentication is needed to grant access.

NEW QUESTION # 47
The following anchor tag is not resolving:
<a href="item.path" >{item.name}</a>
Upon further inspection the developer notices that the link has no .html appended to the end of the URL What could be a potential fix for the issue?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
Explanation
Option B is a potential fix for the issue. Option B uses the data-sly-attribute block statement to add the href attribute to the anchor tag. The data-sly-attribute statement uses an expression to append ".html" to the item.path value. This way, the link will have the correct extension and will resolve to the corresponding page.
