Adobe Experience Manager Sites Developer AD0-E134 Exam Questions
Question 1
An AEM application wants to set up multi-tenancy using Adobe-recommended best practices and bind multiple configurations to it. Which of the following options is recommended?
Question 2
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 3
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
Answer : C
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.
Question 4
What is Out of Scope for the Pattern Detector tool, while doing an AEM upgrade?
Question 5
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)
Question 6
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?
Answer : A
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.
Question 7
Which OSGi configuration values can be used in an AEM as a Cloud Service Implementation?
Answer : D
In AEM as a Cloud Service, the OSGi configuration values that can be used include Inline, secret, and environment-specific. These configurations provide flexibility and security for managing environment-specific settings and sensitive information.
Inline Configurations: Inline configurations are directly embedded within the code and are typically used for straightforward configurations.
Secret Configurations: Secret configurations are used to securely store sensitive information, such as passwords and API keys. These configurations are managed separately to ensure security.
Environment-Specific Configurations: Environment-specific configurations allow you to tailor settings for different environments (e.g., development, staging, production) without changing the underlying codebase.
Example of using these configurations:
Inline Configuration:
{
'service.url': 'https://api.example.com'
}
Secret Configuration: Managed through Adobe IMS and not directly embedded in the code.
Environment-Specific Configuration:
{
'runmode': 'dev',
'service.timeout': '30'
}
