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 a property file stored in the code base
- B. Use a context aware configuration
- C. Read the key value from OSGi configuration stored in run nNdes
- D. Use an environment variable which is then consumed by an OSGi configuration
正解：D
解説：
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:

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 developer keeps control over the app by only enabling authoring in restricted areas of the app
- B. The developer has full control over the app.
- C. The SPA is compatible with the template editor
- D. The content author can edit the app using AEM's content authoring experience.
正解：B
解説：
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

* References:Automating AEM Upgrades
These disadvantages highlight the potential challenges and resource investments needed for an in-place upgrade.
質問 # 48
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 a mock framework in the unit test to inject the CalculationService
- B. Use the feature flag in the unit test to disable the calls to 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 EmployeeService
正解：D
解説：
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:

質問 # 51
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 /content directory
- B. Applying read permissions to anonymous user for /etc directory.
- C. Applying write permissions to anonymous user for/conf directory.
- D. Applying read permissions to anonymous user for /cont directory
正解：A
解説：
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.

質問 # 52
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 OSGI models to export as yaml
2. Configure mime type in Apache Sling Servlet/Script Resolver and Error Handler - C. 1. Create OSGI models to export as yaml
2. Configure mime type in Apache Sling MIME Type Service - D. 1. Create Sling models to export as yaml
2. Configure mime type in Apache Sling Referrer Filter
正解：A
解説：
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.

質問 # 53
SPA components are connected to AEM components via the MapTo() method.
Which code should be used to correctly connect an SPA component called ItemList to its AEM equivalent?
- A. ItemList.MapToCproject/components/content/itemList1);
- B. ('project/components/content/itemList,).MapTo(ltemList,ltemListEditConfig);
- C. MapTo(ltemList)('project/components/content/itemList,,ltemListEditConfig);
- D. MapToCproject/cornponents/content/itemList^ltemListJtemListEditConfig);
正解：A
解説：
Explanation
The MapTo() method is used to map a SPA component to an AEM component by specifying the sling:resourceType of the AEM component as an argument. The MapTo() method should be called on the SPA component and not on a string. The second argument of the MapTo() method is optional and can be used to provide an edit configuration for the SPA component.

Refer to the exhibit.
The current page has three children.
What is the final rendered html output for the code snippet?
- A.
- B.
- C.
正解：B
解説：
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.

質問 # 55
Which configuration/section should be used to resolve the domain name by dispatcher?
- A. Configuration in filters.any
- B. Configuration in httpd.conf
- C. Configuration in DNS
- D. Configuration in vhosts file
正解：D
解説：
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

質問 # 57
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
正解：A
解説：
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:
