NEW QUESTION # 23
An AEM development team is working on a new multi-country application using AEM as a Cloud Service. A developer has been assigned the task for building the integration with a third-party web service. A secret key is needed to connect with this web service. The website creators will provide this key. The key is different for each type of environment (dev, stage and production) What is the recommended way to make the secret key available in the AEM application?
- A. Read the key value from OSGi configuration stored in run nNdes
- B. Use an environment variable which is then consumed by an OSGi configuration
- C. Read the key value from a property file stored in the code base
- D. Use a context aware configuration
Answer: B
Explanation:
Explanation
The recommended way to make the secret key available in the AEM application is to use an environment variable which is then consumed by an OSGi configuration. This way, the secret key is not stored in the code base or in the repository, but rather in a secure and encrypted way in the Cloud Manager environment variables. The OSGi configuration can use a placeholder to reference the environment variable and inject its value at runtime. References:

NEW QUESTION # 24
What is the recommended path to override /libs standard functionality?
- A. /conf
- B. /content
- C. /apps
- D. /Iibs
Answer: C
Explanation:
The recommended path to override /libs standard functionality is /apps. The /apps folder contains application-specific code and configuration that can extend or override the default functionality provided by
/libs. The /apps folder has precedence over the /libs folder, meaning that if there are two resources with the same path under both folders, the one under /apps will be used. References:

NEW QUESTION # 25
How should a developer create a custom log configuration?
- A.
- B.
- C.
Answer: A
Explanation:
To create a custom log configuration in AEM, the developer should create an OSGi configuration file for the org.apache.sling.commons.log.LogManager.factory.writer component. This configuration file should be placed under the appropriate runmode-specific folder within the config directory.
Here is the detailed process:
* Create Configuration File:
* Create a new XML file named
org.apache.sling.commons.log.LogManager.factory.writer-<identifier>.xml in the config.<runmode> folder.
* The <identifier> can be any unique identifier for your custom log configuration.
* Specify Configuration:
* Add the necessary configuration properties within this XML file. For example:
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root
xmlns:sling="http://sling.apache.org/jcr/sling/1.0"
xmlns:jcr="http://www.jcp.org/jcr/1.0"
jcr:primaryType="sling:OsgiConfig"
org.apache.sling.commons.log.file="/var/log/custom.log"
org.apache.sling.commons.log.level="debug"
org.apache.sling.commons.log.pattern="\{0\}"
org.apache.sling.commons.log.names="[com.myproject.custom]" />
* Deploy Configuration:
* Save the configuration file and deploy it to the appropriate environment. The logging system in AEM will pick up this configuration and create a custom log file with the specified settings.

NEW QUESTION # 27
On package install content that is already present in the repos must not be overwritten and if not present in the repos it must not be removed.
Which import mode should the developer use?
- A. replace
- B. update
- C. merge
Answer: B
Explanation:
When installing a package in AEM and you want to ensure that existing content in the repository is not overwritten while ensuring that content not present in the repository is not removed, you should use the update import mode.
The update import mode performs the following actions:
* It updates existing content nodes in the repository with the nodes from the package being installed.
* It does not remove any existing nodes or properties in the repository that are not present in the package.
* It adds any new nodes or properties from the package to the repository.
This mode is particularly useful when you want to preserve any manual changes or additions that might have been made to the repository content outside of the package installations.
Here's how you can specify the import mode during package installation:
* Access Package Manager:
Log into your AEM instance and navigate to the CRX Package Manager (e.g.,
http://localhost:4502/crx/packmgr/index.jsp).
* Upload the Package: If the package is not already uploaded, click on "Upload Package" and select the package file from your local system.
* Install the Package: Click on "Install" for the package you wish to install.
* Choose the Import Mode: During the installation process, you will have the option to choose the import mode. Select update from the available options.
AEM Package Manager - Import Mode
* Complete Installation: Proceed with the installation. The content will be updated according to the rules defined by the update import mode.
By using the update mode, you ensure that your repository content is updated without losing any existing nodes or properties that are not part of the package.
References:
* Adobe Experience Manager Package Manager Documentation
* AEM Import Modes
These steps ensure that you manage content updates in a controlled manner, preserving existing repository content while incorporating updates from the installed package.
NEW QUESTION # 28
An AEM Developer needs to migrate to AEM as a Cloud Service from AEM version 6.4. The AEM Developer is not able to run the Best Practice Analyzer.
What is preventing the Best Practice Analyzer from running?
- A. Best Practice Analyzer should run on Publisher instead of Author instance.
- B. The AEM Developer is not an admin or does not have administrator rights.
- C. Best Practice Analyzer is not supported on AEM version 6.4.
Answer: B
Explanation:
The inability to run the Best Practice Analyzer (BPA) in AEM is most commonly due to the AEM Developer not having the necessary administrative rights. The Best Practice Analyzer is a tool that requires certain permissions to execute, typically administrative privileges.
Here's a detailed explanation:
* Administrator Rights Requirement: The Best Practice Analyzer tool needs access to various parts of the AEM system, including configuration settings and repository data, which require administrator-level permissions. Without these permissions, the tool cannot run properly.
* Permissions Check: Verify that the AEM Developer has admin rights. This can be done by checking the user roles in the AEM User Management console. Ensure that the user is part of the "administrators" group or has equivalent privileges.
* Running BPA: Once the correct permissions are in place, the developer can navigate to the Best Practice Analyzer tool in AEM and execute it. The BPA will then analyze the AEM instance for compliance with best practices.
* Version Compatibility: Note that while this specific issue is related to permissions, it's also important to ensure that the BPA tool version is compatible with the AEM version being used. In this case, the BPA supports AEM version 6.4 and above.
Steps to assign admin rights:
* Log into AEM: As an existing admin, log into the AEM instance.
* Navigate to User Management: Go to Tools > Security > Users.
* Add User to Admin Group: Find the user and add them to the "administrators" group.
* Save and Log Out: Save the changes and ask the user to log out and log back in to acquire the new permissions.
References:
* Adobe Best Practice Analyzer Documentation
* AEM User Management Documentation
These steps should resolve the issue and enable the AEM Developer to run the Best Practice Analyzer tool successfully.
NEW QUESTION # 29
An AEM application is expected to export a content fragment in JSON format without any customization for a headless implementation.
What is the recommended approach?
- A. Use Sling Exporter framework
- B. Use AEM Assets HTTP API
- C. Use Core components to export JSON
Answer: B
Explanation:
AEM Assets HTTP API is a RESTful API that allows access to content fragments in JSON format without any customization. The API supports CRUD operations on content fragments and their variations, as well as querying and searching for content fragments based on metadata or full-text search.References:https://experienceleague.adobe.com/docs/experience-manager-65/assets/extending/assets-api-
NEW QUESTION # 30
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: A
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 # 31
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 Referrer Filter - B. 1. Create Sling models to export as yaml
2. Configure mime type in Apache Sling MIME Type Service - C. 1. Create OSGI models to export as yaml
2. Configure mime type in Apache Sling Servlet/Script Resolver and Error Handler - D. 1. Create OSGI models to export as yaml
2. Configure mime type in Apache Sling MIME Type Service
Answer: B
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 # 32
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. pasteMode-plaintext
- C. defaultPasteMode=plaintext
- D. pasleMode=text
Answer: C
Explanation:
To ensure that text pasted inside the Text component in AEM is stripped of all styling and formatting, you need to override the RTE (Rich Text Editor) plugin implementation and change the default paste behavior. The correct option to achieve this is defaultPasteMode=plaintext.
Steps to configure the RTE plugin for plain text pasting:
* Locate the RTE Configuration: Find the existing configuration for the RTE or create a new one in the
/apps directory of your AEM project.
* Modify the Plugin Configuration: Add or update the configuration to include the defaultPasteMode parameter. The configuration might look something like this:
{
"jcr:primaryType": "nt:unstructured",
"features": "[text]",
"defaultPasteMode": "plaintext"
}
* Apply the Configuration: Ensure that this configuration is applied to the Text component. This typically involves updating the component dialog or design dialog to reference the updated RTE configuration.
* Test the Configuration: In the AEM author instance, open the page with the Text component and paste text using CTRL+V. The pasted text should now be stripped of all styling and formatting, adhering to the plaintext mode.
By setting defaultPasteMode to plaintext, you ensure that the RTE only accepts plain text input, removing any formatting that might come from external sources.

NEW QUESTION # 33
AEM SPA integration provides various design models. In an application the developer chooses to use AEM as a headless CMS without using the SPA Editor SDK framework.
What would be an advantage for this design model?
- A. The content author can edit the app using AEM's content authoring experience.
- B. The developer keeps control over the app by only enabling authoring in restricted areas of the app
- C. The developer has full control over the app.
- D. The SPA is compatible with the template editor
Answer: C
Explanation:
AEM SPA integration provides various design models for different levels of authoring capabilities and developer control. In the design model where AEM is used as a headless CMS without using the SPA Editor SDK framework, the developer has full control over the app and can use any SPA framework or library.
However, this also means that the content author cannot edit the app using AEM's content authoring experience, the SPA is not compatible with the template editor, and the developer cannot enable authoring in restricted areas of the app.References:https://experienceleague.adobe.com/docs/experience-manager-learn/spa-editor-overview/spa-ove
NEW QUESTION # 34
A customer adds third-party client libraries to add some features in an existing AEM application, which will significantly reduce performance.
How should the developer optimize the site?
- A. Debug third-party client lib and fix the code.
- B. Rebuild Client libraries.
- C. Embed client libraries to consolidate them into fewer files.
Answer: C
Explanation:
Embedding client libraries is a technique that allows combining code from multiple client libraries into a single file. This reduces the number of network requests and improves performance. Embedding client libraries can be done by using the embed property of the cq:ClientLibraryFolder node and specifying the categories of the client libraries to be embedded. References:

NEW QUESTION # 35
If multiple configurations for the same PID are applicable, which configuration is applied?
- A. The last modified configuration is applied.
- B. The one that occurs first in the repository is applied.
- C. A configuration factory is created and all configurations are applied.
- D. The configuration with the highest number of matching run modes is applied.
Answer: D
Explanation:
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.References:https://experienceleague.adobe.com/docs/experience-manager-65/deploying/configuring/con
NEW QUESTION # 36
The OSGi configuration is added to a runmode specific configuration "config.author.staging" in AEM as a Cloud Service. The application fails to read the configuration.
What is a possible cause of this issue?
- A. The custom OSGi configuration runmode used (i.e., "config.author.staging") is not supported in AEM as a Cloud service.
- B. AEM as a Cloud service does not support OSGi configuration runmodes.
- C. Only <service> specific OSGi configuration runmodes like "config.author" or "config.publish" are supported in AEM as a Cloud service.
- D. OSGi configuration runmodes cannot be installed automatically on AEM as a Cloud Service. We need to install them as a package using the Package manager.
Answer: C
Explanation:
AEM as a Cloud Service does not support custom OSGi configuration runmodes, such as
"config.author.staging". Only <service> specific OSGi configuration runmodes, such as "config.author" or
"config.publish", are supported. These runmodes are used to apply configurations to specific services, such as author or publish. The <service> specific runmodes can be combined with environment variables to achieve different configurations for different environments. References:

In an AEM as a Cloud Service environment, which repository areas are considered as immutable?
- A. /apps and /libs
- B. /content and /etc
- C. /apps and /content
- D. /content and /libs
Answer: A
Explanation:
In AEM as a Cloud Service environment, the repository areas /apps and /libs are considered as immutable, meaning that they cannot be modified at runtime by any means. These areas contain application code and configuration that are deployed via Cloud Manager and are read-only for security and performance reasons.
Any changes to these areas require a new deployment via Cloud Manager. References:

NEW QUESTION # 43
A snippet throws an exception at runtime:
@Model(adaptables = {Resource.class}) public class MyCustomModel {
(SSIingObject
private Resource resource;
What should the developer add to fix it?
- A. (Optional annotation to page field
- B. SlingHttpServletRequest.class to adaptables property of Model Class annotation
- C. defaultlnjectionStrategy = DefaultlnjectionStrategy property to @Model Class annotation
- D. throws Exception at the end of the init method declaration
Answer: C
Explanation:
Explanation
The developer should add the defaultInjectionStrategy = DefaultInjectionStrategy property to the @Model Class annotation to fix the snippet. The defaultInjectionStrategy property defines how the Sling Model handles missing or null values for the injected fields. By default, the Sling Model uses the REQUIRED injection strategy, which means that all fields must have a non-null value or else an exception is thrown. By setting the defaultInjectionStrategy property to OPTIONAL, the Sling Model allows null values for the injected fields and does not throw an exception. This way, if the page field is null because the resource is not a page, the Sling Model can still work without errors. References:
