It defines the type of the rule, such as \"Allow\" or \"Deny\", indicating whether to permit or block certain requests. The **/type** attribute is fundamental because it directly specifies the action that the Dispatcher should take when a rule is matched. Other attributes like **/glob**, **/selectors**, and **/url** are used to detail the criteria of the filtering, but the **/type** attribute is crucial for the rule to be valid and functional. **Additional Notes:** **Attribute** **Short Description** **Example** --------------- ---------------------------------------------------------------------- ------------------------------------------------------- /type Determines if the rule allows or denies requests. **/type \"deny\"** /selectors Filters requests based on AEM selectors in the URL. **/selectors \"(print\|export)\"** /url Matches requests based on the full URL. **/url \"http://www.example.com/content/page.html\"** /glob Specifies patterns for matching URLs or paths using wildcards. **/glob \"\*.html\"** /path Filters requests based on the path of the requested resource. **/path \"/content/mysite/\*\"** /extension Matches requests based on the file extension. **/extension \"html\"** /method Filters requests based on the HTTP method used (GET, POST, etc.). **/method \"GET\"** /query Matches requests based on the presence of specific query parameters. **/query \"id=123\"** /clientheader Filters requests based on specific HTTP request headers. **/clientheader \"User-Agent\"** Answer 2 -------- **The correct answer to the [[question]](#question-2) is: C** This option provides a comprehensive approach to setting up application logging by configuring both the aspects of logging: what to log (through the Logger Configuration) and how to write those logs (through the Writer Configuration). **[Additional notes:]** **Apache Sling Logging Logger Configuration:** This configuration is used to define individual loggers in Apache Sling. It allows you to specify the log level, the logger name, and the log file to which the logger should write. This is essential for controlling what messages (like DEBUG, INFO, ERROR) are logged and where they are stored. **Apache Sling Logging Configuration:** This is a more general configuration for the overall logging mechanism in Apache Sling. It typically includes settings for the root logger, default log levels, and overall logging behavior. It does not deal with specific loggers or output destinations but sets the baseline for the logging framework. **Apache Sling Request Logger:** This configuration is specifically used for logging HTTP requests in Sling. It can be configured to log details about incoming requests and responses. This is particularly useful for debugging and monitoring the traffic handled by the Sling application. **Apache Sling Logging Writer Configuration:** This configuration is used to define how and where log messages are written. It includes settings for log writers, such as file writers or console writers, specifying the format, location, and rotation policy for log files. This is key for managing the output of log messages and ensuring they are stored or displayed in an appropriate manner Answer 3 -------- The correct answer to the [[question]](#question-3) is C: Explanation: - The **/docroot** property in the **/cache** section of the **dispatcher.any** file specifies the root directory for the Dispatcher\'s cache. This is where the Dispatcher stores its cached files, mirroring the structure of the content as it is on the publish instance. - The other options provided have different purposes: - **/invalidate:** This property is used to define rules for cache invalidation, not for specifying the cache directory. - **/statfile:** This property defines the name of the file used by the Dispatcher to track when the cache content was last invalidated. It\'s not a directory path. - **/cacheroot:** While this sounds like it could be the correct answer, it is not a standard property in the Dispatcher\'s configuration. The correct property for the cache directory is **/docroot**. Answer 4 -------- The correct answer to the [[question]](#question-4) is C: Explanation - AEM as a Cloud Service introduces the concept of \"secrets\" for handling sensitive data, such as private API keys. - These secrets are stored securely and can be accessed in the application via a specific syntax. - The syntax **\$\[secret:SECRET\_VAR\_NAME\]** is used to reference these stored secrets. **SECRET\_VAR\_NAME** would be the name of the specific secret (environment variable) that you have configured. - This method ensures that sensitive data like API keys are not exposed in the codebase and are managed securely according to best practices in cloud environments. Answer 5 -------- The correct answer to the [[question]](#question-5) is B. **Explanation:** - AEM uses the concept of run modes to determine which configurations should be active in a given instance. Run modes allow for the differentiation between environments like development, staging, and production. - When there are multiple configurations for the same OSGi component (same PID), AEM determines which configuration to apply based on the run modes. - The system selects the configuration that has the highest number of run modes matching the run modes of the current AEM instance. - This approach ensures that the most specific configuration applicable to the current environment is the one that gets used. In summary, the choice of configuration is based on the relevance to the current operational context of the AEM instance, as indicated by its run modes. Answer 6 -------- The correct answer to the [[question]](#question-6) is C. To resolve the domain name by the dispatcher, the appropriate configuration is: C. **Configuration in httpd.conf** Explanation: - **httpd.conf**: This is the main configuration file for the Apache HTTP Server, which is often used as the web server in front of the AEM dispatcher. Domain names and virtual hosts are typically configured here, allowing the Apache server (and thereby the dispatcher) to resolve domain names to specific AEM instances or environments. Within this file, you can specify **VirtualHost** directives to handle different domain names and route traffic appropriately. - **vhosts file**: While virtual host configurations can be included in the **httpd.conf** file directly, AEM\'s dispatcher often uses separate **vhost** files for organization. However, the inclusion of these **vhost** files and the resolution of domain names to specific configurations still originates from directives within the **httpd.conf** file. - **filters.any**: This file is used for configuring Dispatcher filters, which control what content can be cached or blocked by the Dispatcher. It is not used for resolving domain names. - **DNS (Domain Name System)**: While DNS is responsible for resolving domain names to IP addresses at the network level, the specific handling of domain names to AEM instances or configurations is managed by the web server (Apache) and dispatcher configurations, not DNS settings directly. In summary, domain name resolution in the context of directing traffic to the appropriate AEM instance via the dispatcher is configured in the **httpd.conf** file of the Apache HTTP Server, where **VirtualHost** directives are defined to handle different domains. Answer 7 -------- the correct answer to the [[question]](#question-7) is **D. /enableTTL \"1\"**. Explanation: This configuration allows the Dispatcher to evaluate the TTL information in the HTTP response headers from AEM and automatically refresh its cache when the TTL expires, ensuring the content served is up-to-date. Answer 8 -------- The correct answer to the [[question]](#question-8) is B. **Explanation:** - In AEM as a Cloud Service, the configuration management follows a slightly different approach compared to traditional AEM setups. The configurations are more cloud-centric and follow the principles of immutable infrastructure. - **ui.config Project:** The **ui.config** project or module in the AEM project structure is specifically designated for holding OSGi configurations. Placing configurations in this module aligns with AEM as a Cloud Service\'s deployment practices. - **Runmode-Specific Folder:** Within the **ui.config** module, the configurations are typically organized into runmode-specific folders. For example, if you have a configuration for the **author** runmode, it would go into a folder named **config.author**. - This approach ensures that the configurations are applied based on the runmode of the AEM instance, whether it's an **author** or **publish** instance, or any other custom runmode that might be in use. - **Other Options:** - **A. Core Project:** Typically used for Java code (OSGi services, servlets, models). - **C. All Project:** Generally used for assembling all parts of the project into a complete package. - **D. ui.apps Project:** Mainly used for application content such as components, templates, client libraries, etc. By following this structure, you ensure that your OSGi configurations are managed in a way that's consistent with AEM as a Cloud Service's best practices, leveraging its cloud-native features for configuration management. Answer 9 -------- The correct answer to the [[question]](#question-9) is D. **Explanation:** - **Use of OSGi R6 Annotations:** This option uses OSGi Declarative Services (R6) annotations, which is the modern and recommended way of defining OSGi components and services in AEM. The **\@Component** annotation is used to declare an OSGi service. - **Factory Configuration:** The **factory=true** attribute in the **\@Designate** annotation indicates that this is a factory configuration, meaning it can be instantiated multiple times. This is essential for multi-tenancy, where you might need different configurations for different tenants. - **Object Class Definition (OCD):** The **ocd** attribute in the **\@Designate** annotation points to the Object Class Definition that defines the structure of the configuration. This aligns with best practices for clear and maintainable configuration structures. **Other Options:** - **A:** Uses the older Felix SCR annotations, which are not recommended in newer versions of AEM that support OSGi R6 annotations. - **B:** Lacks the **\@Designate** annotation and does not specify the OCD, which is essential for defining the structure of the configuration. - **C:** Only includes meta-type annotations for defining the configuration structure but does not define an OSGi service component or indicate that it\'s a factory configuration. Option D is the most comprehensive and aligns with the best practices for AEM as a Cloud Service and modern AEM development, supporting multi-tenancy and allowing for multiple configurations. Answer 10 --------- The correct answers to the [[question]](#question-10) are D and E Explanation: For integrating LDAP services with an AEM application to synchronize users and groups, the required OSGi configurations are related to external authentication and user synchronization. Among the provided options, the two configurations required for LDAP integration in AEM are: 1. **D. Apache Jackrabbit Oak External Login Module** - This module is responsible for handling external authentication, such as connecting to an LDAP service. It allows AEM to authenticate users against an LDAP directory, facilitating the integration of AEM with LDAP for user authentication. 2. **E. Apache Jackrabbit Oak Default Sync Handler** - The Default Sync Handler is used for synchronizing user and group information from the external authentication system (like LDAP) into the AEM repository. It ensures that user and group data in AEM are kept in sync with the LDAP directory. **Explanation of Other Options:** - **A. Apache Jackrabbit Oak AuthorizableActionProvider:** - This is related to actions performed upon creation, modification, or deletion of authorizables (users and groups) but is not specifically for LDAP integration. - **B. Apache Jackrabbit Oak Solr server provider:** - This configuration is related to integrating Apache Solr for search capabilities in AEM and is not relevant to LDAP integration. - **C. Apache Jackrabbit Oak CUG Configuration:** - CUG (Closed User Group) configuration is for restricting access to specific content areas within AEM and is not directly related to LDAP integration. In summary, for LDAP Service integration in AEM, focusing on the Apache Jackrabbit Oak External Login Module and the Apache Jackrabbit Oak Default Sync Handler is essential, as these handle the core aspects of authentication and synchronization with the LDAP directory. Answer 11 --------- The correct answer to the [[question]](#question-11) is B To address the client\'s issues with query results, especially considering that users are not always searching with exact wording and are using short phrases, the focus should be on enhancing the search functionality to accommodate synonyms and potentially disregard common, less meaningful words (stop words). Based on this, the AEM developer should recommend: - **Option 2:** 1. **Add a synonyms filter to the current indexes:** This allows the indexing process to consider synonyms of terms. For example, if the client has industry-specific jargon or terms that have similar meanings, the synonyms filter can help index these terms more effectively, enabling users to find relevant results even if they don\'t use the exact term. 2. **Add a lowercase filter to the current indexes:** This ensures that the search is case-insensitive, which is important because users may not always use the correct case when searching. It helps standardize the indexed terms for more consistent search results. **Explanation of Other Options:** - **Option 1:** - A mapping filter can be useful, but it\'s more about correcting for variations in spelling rather than addressing synonyms. - A stop filter removes common words (like "and", "the", etc.) from the index. This might not be as effective in this scenario if the issue is more about synonym matching and phrase searches. - **Option 3:** - A keyword tokenizer treats the entire input as a single token, which isn\'t ideal for phrase searches where individual word relevance is important. - While a mapping filter can correct variations in spelling, it doesn\'t address the synonym issue. - **Option 4:** - While adding a synonyms filter is beneficial, adding a stop filter might not be the best choice if users are searching with phrases where common words could be significant to the context of the search. In summary, **Option 2** is the most suitable recommendation. It enhances the search functionality in AEM to better handle variations in user search behavior, such as using synonyms or different phrasings, while ensuring case insensitivity in searches. Answer 12 --------- The answer to the [[question]](#question-12) is D. **Explanation:** - **Maximum Parallel Jobs:** This setting, found in the OSGi console, specifically controls the number of workflows that can be executed in parallel. By reducing this number, you can limit the concurrent execution of workflows, thereby reducing the load on the server caused by workflows. **Why Not the Other Options?** - **A. The number of threads in Scheduler:** The Scheduler\'s thread pool is used for scheduled tasks, not specifically for workflow execution. Adjusting this would not directly impact the workflow concurrency. - **B. The number of threads in Apache Felix Jetty Http Service:** This configuration relates to the HTTP service\'s thread pool, which handles incoming HTTP requests. It is not directly related to the execution of workflows. - **C. Launchers for each workflow:** While you could technically disable or adjust workflow launchers (which trigger workflows based on certain events or conditions), this approach isn\'t about limiting concurrency but rather controlling when and if certain workflows are triggered. It\'s not as direct or effective for managing concurrent workflow execution as adjusting the \"Maximum Parallel Jobs.\" **Implementing the Change:** To adjust the \"Maximum Parallel Jobs\" setting: 1. Go to the AEM OSGi console (usually at **http://\[your-aem-instance\]/system/console/configMgr**). 2. Find the configuration for the Workflow Engine (often titled something like \"Apache Sling Workflow Engine\" or \"AEM Workflow Engine\"). 3. Locate the \"Maximum Parallel Jobs\" setting and adjust it to the desired number to control the parallel execution of workflows. 4. Save the configuration. This change should help manage the server load by limiting how many workflows can run concurrently. This change is a direct and effective way to manage the load caused by workflows on an AEM server. Answer 13 --------- The correct answers to the [[question]](#question-13) are B and C Explanation: Option B is correct because it uses the **\@Inject** annotation to inject the value of the **title** property from the dialog. The **init()** method then checks if **title** is not blank and sets **messageText** accordingly. Option D is also correct because it uses the **\@ValueMapValue** annotation with the **name** parameter to explicitly map the **title** property from the dialog to the **authoredVal** field in the Sling Model. Answer 14 --------- The correct answer to the [[question]](#question-14) is C. **Explanation:** - **Proxy Component:** Creating a Proxy Component from the core Title component allows you to leverage the existing layout and functionality of the core Title component, which satisfies the first requirement. A proxy component inherits everything from the core component but allows you to override certain aspects. - **Custom Sling Model:** By creating a Custom Sling Model that overrides the default behavior, you can prepend the page title to the component text, satisfying the second requirement. This Sling Model would fetch the page title and concatenate it with the component text. - **Reusability:** Using a proxy component ensures that you are extending a core component, making the new component reusable across projects and environments, which meets the third requirement. **Why Not the Other Options?** - **Option A:** Option A is similar to Option C, but it also mentions customizing the component template. This might not be necessary if the layout of the Title core component already meets the layout requirement. Overriding the Sling Model should be enough to prepend the page title without needing to change the template. - **Option B:** Creating a custom component from scratch isn\'t recommended when you can reuse the existing core Title component. It would involve unnecessary duplication of effort and code, and it wouldn\'t be as maintainable as extending the core component. In conclusion, Option C is the most efficient and maintainable approach that leverages existing functionality and follows best practices for AEM development. Answer 15 --------- The correct answer to the [[question]](#question-15) is A. Considering the requirements and the code provided, **Option A** is the most appropriate method to represent the model in HTL. - This option has the correct **data-sly-use.byline** statement to use the **Byline** interface. - The **\@join** option is correctly used with the **occupations** field. - This option assumes that the **empty** property is available to determine if the model has content. If not, this property must be defined in the **Byline** interface or class. Answer 16 --------- The correct answer to the [[question]](#question-16) is B The correct answer, Option B, uses the **MapTo()** function in the syntax that aligns with the AEM SPA Editor SDK\'s requirements for connecting SPA components to AEM components. Here\'s a brief explanation: - **MapTo() Syntax:** In AEM\'s SPA Editor SDK, **MapTo()** is a higher-order function used for mapping SPA components to AEM components. The function takes the **sling:resourceType** of the AEM component as its first argument and returns another function. - **SPA Component Mapping:** The returned function is then called with the SPA component and an optional configuration object. This step effectively connects the SPA component with the specified AEM component. - **Option B Structure:** Option B correctly implements this pattern: This structure ensures that the **ItemList** SPA component is correctly linked to its AEM counterpart, allowing content authored in AEM to be rendered and managed through the **ItemList** component in the SPA. Answer 17 --------- The correct answer to the [[question]](#question-17) is D. Explanation: The **data-sly-list** directive iterates over a collection and repeats the element it is declared on (and its children) for each item in the collection. Given that the current page has three children, the **li** element inside the **ul** with **data-sly-list** will be repeated three times within the same **ul**. The **data-sly-repeat** directive behaves similarly, but it repeats the entire element it\'s declared on for each item in the collection. This means that the **ul** element with **data-sly-repeat** will be repeated three times, each with a single **li**. Additional info:\ \ The **MapTo()** function in Adobe Experience Manager (AEM) is a crucial part of the SPA Editor SDK, facilitating the integration of Single Page Application (SPA) frameworks like React or Angular with AEM\'s content management capabilities. Here\'s a brief explanation of its role and functionality: **Purpose of MapTo():** - **Connects SPA Components to AEM Components:** **MapTo()** is used to map SPA components (like a React or Angular component) to corresponding AEM components defined by their **sling:resourceType**. - **Enables Dynamic Rendering:** This mapping allows dynamic rendering of content managed in AEM through the SPA components, making the SPA compatible with AEM\'s content authoring and management features. **How MapTo() Works:** - **Higher-Order Function:** **MapTo()** is a higher-order function. It first takes the **sling:resourceType** of the AEM component as an argument and returns a new function. - **Component Binding:** The returned function is then called with the SPA component and an optional edit configuration object. This step binds the SPA component to the AEM component, allowing the SPA to render content based on AEM\'s content structure and data. **Usage Pattern:** - **Syntax:** The typical usage pattern is as follows: **Role in AEM SPAs:** - **Integrating Front-end and Back-end:** **MapTo()** serves as a bridge between the front-end SPA components and the AEM back-end, ensuring that the SPA can effectively display and interact with content managed in AEM. - **Supporting AEM Authoring:** It supports AEM\'s authoring capabilities, allowing content authors to use AEM\'s tools to manage and edit content that will be rendered by the SPA. In summary, the **MapTo()** function is key to developing SPAs in AEM, ensuring seamless integration between AEM\'s powerful content management system and modern SPA frameworks. Answer 18 --------- The correct answer to the [[question]](#question-18) is A. The developer should implement the following method from the **com.day.cq.workflow.exec.ParticipantStepChooser** interface: **\ [getParticipant]**(**[WorkItem]** workItem,  **[WorkflowSession]** workflowSession, **[MetaDataMap]** args) This method is used to dynamically determine the participant of a workflow step at runtime. It returns a **String** representing the user or group ID that should be assigned to the participant step. The **WorkItem**, **WorkflowSession**, and **MetaDataMap** parameters provide the necessary context and data to make this determination. Answer 19 --------- The correct answer to the [[question]](#question-19) is D. **Explanation of Choice:** - **Centralized Management:** Experience Fragments in AEM allow for the creation of reusable content pieces (like headers and footers) that can be authored once and used across multiple pages. - **Variations:** Experience Fragments support the creation of multiple variations, enabling different versions of the Header and Footer to be created and used as needed. - **Scheduled Changes:** AEM\'s Experience Fragments can be integrated with Launches, allowing for the scheduling of content changes. This feature enables the Header and Footer to be changed for specific time periods. - **Versioning:** Experience Fragments benefit from AEM\'s versioning capabilities, allowing previous versions to be restored if necessary. **Why Not the Other Options?** - **A. Custom Component:** While custom components are flexible, they don\'t inherently provide the centralized management, scheduling, and versioning capabilities required for this use case. - **B. Content Fragment:** Content Fragments are primarily used for headless content delivery and lack the layout/design capabilities that might be needed for headers and footers. They also don't directly support scheduled variations. - **C. Static Template:** Static templates offer less flexibility for creating variations and scheduling content changes compared to Experience Fragments. - In summary, Experience Fragments offer the combination of reusability, variation management, scheduling capabilities, and versioning, making them the most suitable choice for this requirement. Answer 20 --------- The correct answer for the [[question]](#question-20) is B Explanation When using AEM as a headless CMS without the SPA Editor SDK framework, the front-end developers have full control over the application. They are responsible for the entire front-end architecture, including the SPA\'s structure, layout, and interactivity, independent of AEM\'s authoring capabilities. Answer 21 --------- The correct answer to the [[question]](#question-21) is A. **Explanation** The Teaser component in AEM\'s Core Components can handle text, images, and links, aligning well with the requirement. Extending this component and using the Style System allows for creating multiple design variations without needing to modify the component\'s code. Answer 22 --------- The correct answer to the [[question]](#section) is A. **Detailed Explanation:** - **AEM Assets HTTP API Overview:** - Adobe Experience Manager (AEM) offers a comprehensive HTTP API that allows for programmatic access to AEM assets, including content fragments. - This API is designed for headless content delivery, where AEM serves as a content repository that can be accessed by external applications and services. - **Content Fragments and JSON Export:** - Content fragments in AEM are pieces of reusable content that can be authored independently of their use on pages or in applications. - The AEM Assets HTTP API enables the retrieval of these content fragments in JSON format. This feature is particularly useful for headless CMS implementations, where content managed in AEM needs to be delivered to various channels in a structured format like JSON. - **Headless Implementation:** - In a headless CMS approach, the content management and content delivery layers are decoupled. AEM acts as a backend content repository, and the content is consumed via APIs by various front-end applications (like SPAs or mobile apps). - Using the AEM Assets HTTP API for content fragment export fits well into this architecture, as it allows external applications to fetch content from AEM in a format that\'s easy to consume (JSON). - **No Customization Needed:** - The question specifies that the export of content fragments should happen without any customization. The AEM Assets HTTP API supports this requirement out of the box, allowing for the straightforward retrieval of content in JSON format without the need for additional development or customization. - **Why It\'s Recommended:** - The use of AEM Assets HTTP API is a recommended approach in this scenario due to its simplicity, effectiveness, and alignment with headless CMS principles. It provides a ready-to-use, standard way of accessing AEM content fragments, ensuring compatibility and ease of integration with various front-end technologies. In summary, for exporting AEM content fragments in JSON format, especially in a headless CMS context, the AEM Assets HTTP API is the most straightforward and effective solution, aligning well with the requirements of modern digital experiences that rely on decoupled content management and delivery architectures.

It can include properties that control how these assets are loaded and combined. - **Embed Property:** - The **embed** property within a client library folder (**cq:ClientLibraryFolder** node) is used to include the assets of another client library within the current one. - By using the **embed** property, you can combine multiple JavaScript files from various client libraries into a single aggregated file. This effectively reduces the number of HTTP requests made to load these scripts. - **Why This Approach?** - This approach is particularly useful in AEM for managing client-side resources efficiently. - It enhances page performance by reducing the number of individual file requests and therefore the load time of a page. - It maintains the modularity of client libraries while optimizing their delivery to the client. **Why Not the Other Options?** - **A. Using allowProxy:** While **allowProxy** is used to enable client libraries to be proxied through the dispatcher, it does not inherently combine multiple libraries into a single file. - **B. Using categories:** Simply adding the categories property to a client library folder does not combine the files into one; it just categorizes the libraries for easier inclusion. - **C. Using dependencies:** The **dependencies** property ensures that one library is loaded after its dependencies, but like the **categories** property, it doesn\'t combine the files into one. **Conclusion:** For reducing the number of **\** tag requests on an AEM website, embedding required libraries into a single app-specific client library using the **embed** property is the most effective approach. This method optimizes the loading of JavaScript files, improving the overall performance of the website. Reference [[https://experienceleague.adobe.com/docs/experience-manager-65/developing/introduction/clientlibs.html?lang=en]](https://experienceleague.adobe.com/docs/experience-manager-65/developing/introduction/clientlibs.html?lang=en) Answer 24 --------- The correct answer to the [[question]](#question-24) is C. **Explanation:** The use of the Adobe Client Data Layer (CDL) integrated with Core components in AEM is recommended for managing an event-driven data layer, particularly for analytics solutions. CDL provides a structured, standardized way to represent the content and state of AEM components and pages, making it efficient for data management and ensuring consistency across the application. This approach simplifies the implementation and management of analytics tracking and other event-based functionalities, aligning with Adobe\'s best practices. Answer 25 --------- The correct answer to the [[question]](#question-25) is C. - **Use a Mock Framework to Inject the EmployeeService:** - **Isolation of the Service Under Test:** By using a mock framework (like Mockito) in unit tests, you can create mock instances of dependencies, in this case, the **EmployeeService**. This allows you to isolate the **CalculationService** and test it independently of its dependencies. - **Control Over Test Scenarios:** Mocking **EmployeeService** enables you to specify the behavior of this dependency during tests. You can define how the mocked **EmployeeService** should respond to certain method calls, which is crucial for testing different scenarios and edge cases in **CalculationService**. - **Increased Test Coverage and Reliability:** Because you\'re isolating the service and controlling the behavior of its dependencies, you can cover more code paths and scenarios in **CalculationService**. This leads to more thorough testing and higher code coverage. - **No Real Service Interaction:** Mocking eliminates the need for actual service interaction, which can be time-consuming and error-prone, especially if the real service has its own dependencies, external calls, or side effects. **Why Not the Other Options?** - **A. Inject the CalculationService:** This doesn\'t address the dependency on **EmployeeService**, which is crucial for testing **CalculationService**. - **B. Instantiate EmployeeService in the Test:** Direct instantiation might not be feasible or desirable, especially if **EmployeeService** has its complexities or external dependencies. - **D. Use Feature Flag to Disable Calls:** This approach might not be viable or effective for unit testing, as it doesn\'t provide the necessary control over the behavior of **EmployeeService**. **Conclusion:** For unit testing **CalculationService** effectively, mocking its dependency (**EmployeeService**) provides the control, isolation, and flexibility needed to achieve high test coverage and ensure the reliability of the tests. Top of Form Bottom of Form Answer 26 --------- The correct answer to the [[question]](#question-26) is C. To meet the requirement for Sling Models to export data in a human-readable YAML format, the appropriate method would be: C. **Option C** 1. Create Sling models to export as yaml 2. Configure mime type in Apache Sling MIME Type Service Explanation: - **Create Sling Models**: Sling Models are Java POJOs that are annotated with **\@Model** annotations, making them adaptable from Sling HTTP requests and resources. They are used to map resource properties to Java objects. - **Export as YAML**: The Jackson dataformat YAML dependency that you have in your Maven project allows you to serialize and deserialize objects to and from YAML. It\'s necessary to implement the **ModelExporter** interface in your Sling Model in such a way that it can produce YAML output. - **Configure MIME Type**: Apache Sling MIME Type Service is responsible for determining the correct MIME type for a given request. Since YAML is not a commonly used format in web applications out of the box, you would need to add **text/yaml** or **application/x-yaml** (depending on the specific MIME type you want to use for YAML) to the MIME Type Service configuration to properly serve the YAML formatted data. The other options are less suitable: - **A & B**: While these options correctly suggest creating models to export as YAML, they mention configuring the MIME type in services that are not directly responsible for determining the MIME type based on file extensions or content types. - **D**: The Apache Sling Referrer Filter is not related to MIME types or Model Exporters; it is used for CSRF protection by filtering HTTP requests based on the HTTP Referrer header. In summary, Option C is the correct approach, which involves creating Sling Models capable of exporting data in YAML format and configuring the MIME Type Service to serve the correct content type for YAML. Answer 27 --------- The correct answer to the [[question]](#question-27) is C. **Explanation** For creating a custom workflow process step in Adobe Experience Manager (AEM), the developer needs to implement the WorkflowProcess interface. The method that should be implemented in an OSGi component for this purpose is: 'execute' - **WorkflowProcess Interface:** In AEM, the **WorkflowProcess** interface is used to define custom process steps in workflows. This interface requires the implementation of a specific method to handle the workflow execution logic. - **execute Method:** The **execute** method is the key method in the **WorkflowProcess** interface. It contains the business logic that is executed when the workflow step runs. The method signature is as follows: - **workItem**: Represents the current work item in the workflow. - **workflowSession**: Provides access to the workfl
