To start an AEM instance in debug mode automatically, without manually providing JVM parameters each time, a developer can add the required JVM parameters to the AEM instance's start script. This script is executed every time the AEM instance is started, and by including the debug parameters there, the instance will automatically start in debug mode each time. The start script is typically namedstart.bat(for Windows) orstart.sh(for Unix-based systems) and is located in the AEM installation directory.

• Adding JVM parameters to a properties file under a run mode-specific directory (Option A) or setting an OSGi configuration (Option B) are not standard methods for configuring JVM debug parameters for AEM startup.

In Maven, themaven-clean-pluginis used to clean the project by removing files generated at build-time in thetargetdirectory. Before a new build, cleaning the project is a common practice to ensure that no stale artifacts affect the new build. The plugin's goalcleanis bound to the clean phase of the build lifecycle and can be executed with the commandmvn clean.

• Option A,mvn-clean-plugin, is incorrectly named; the correct name ismaven-clean-plugin.
• Option B,maven-scr-plugin, is related to Service Component Runtime and not to cleaning build artifacts.

In HTL, theformatoption in the data-sly-use or data-sly-test attribute can be used to format values according to a pattern. The pattern'-#.##%'indicates that the number should be formatted as a percentage with up to two decimal places. ThepiValuevariable would be the number to format, and in this example, it would convert -3.14 to -314%. The@symbol is used to denote the use of an option with the variable in HTL.

• Options B and C are incorrect because they do not use the correct syntax for the format option in HTL. The use of@is to specify options and not part of the variable or pattern itself.

Sling Models is an AEM feature that allows developers to map JCR data to Java objects. It is a part of the Sling framework, which AEM is built on top of. Sling Models facilitate the decoupling of content from the rendering layer, making it easier to work with data in AEM components. By defining simple POJOs (Plain Old Java Objects) with annotations, developers can map properties from the JCR (Java Content Repository) to fields in a Java class, enabling a straightforward and type-safe way to handle the content. This is especially useful when creating components such as 'Hello World', where dynamic data needs to be fetched from the JCR and rendered on the page.

• HTL and Dialogs (Option A) are used for rendering components and creating editable fields in the component dialogs, respectively, but do not facilitate data mapping to Java variables.
• Client-Side Libraries (Option B) are used to manage client-side resources like JavaScript and CSS but are not involved in JCR to Java variable mapping.

AEM as a Cloud Service includes the latest AEM features out-of-the-box, including AEM Core Components, which are production-ready without the need for additional downloads or installations of sample content. This version of AEM has a continuousdelivery model, ensuring that the most up-to-date features and components are readily available.

• Option A, Version 6.3, is incorrect because this version would require the manual download and installation of core components.
• Option B, Adobe Managed Services, is not a version of AEM, but rather a hosting option that could include various versions of AEM.

To create new content fragments programmatically in AEM, a developer would typically use an API provided by AEM for content fragment operations. Among the options given,FragmentTemplate.createFragment()seems to be the most fitting API method call, as it implies the use of a template to create a fragment. In practice, the Content Fragment Java API provides methods to create and manage content fragments in AEM by interacting with the underlying JCR (Java Content Repository). However, without specific API documentation, I'm relying on provided patterns that align with typical AEM Java API usage.

When customizing a core component in AEM, setting thesling:resourceSuperTypeproperty in the new component's definition allows it to inherit features from an existing core component. This property points to the resource type of the core component that is being extended or customized. By doing so, the new component inherits the core component's logic and rendering scripts but can be customized further according to project-specific requirements.

• Option A,sling:resourceType, is used to define the primary resource type for a component and does not indicate inheritance.
• Option B,jcr:title, is used to give a human-readable title to a node in the JCR and is unrelated to component inheritance.

In AEM, when you need to extend a dialog from a core component but want to hide or exclude one tab or part of the dialog, you can use thesling:hideResourceproperty. This property allows you to selectively hide resources (like a tab in a dialog) inherited from a super type (the core component) in your overlay or custom component.

When defining a blueprint configuration in AEM, the content author must adhere to certain structure rules to ensure the proper functioning of the live copy mechanism. The rules include:

B. The immediate child pages of the root are language branches of the website - This structure is commonly used in AEM to organize content according to language and regional variations, allowing for more manageable and scalable content management across different locales.

D. The website should have a single page as the root - Having a single root page for a website is a standard practice in AEM as it simplifies the content hierarchy and providesa clear entry point for the site structure. This root page then serves as the source for live copies.

Options A and C are not strict requirements for a blueprint configuration. AEM does not mandate that the root of each language branch has at least two child pages or that each language page must have a country child page. These decisions are usually based on the specific content structure and organizational needs of the website.

When accessing the Automated Maintenance Tasks in AEM via the specified URL, the default timing card available is the "Daily Maintenance Window". AEM provides a set of pre-configured maintenance tasks that can be run on a daily, weekly, or monthly basis, but the daily window is the standard default card that is presented in the maintenance console for configuring these tasks.

• Monthly Maintenance Window (Option B) and Quarterly Maintenance Window (Option C) are not the default options that are presented in the AEM maintenance console.

Given the dispatcher configuration snippet provided in the image, we can understand the URL patterns that will be ignored (not cached) by the dispatcher. The configuration under/ignoreUrlParamsshows patterns to match query parameters in the URLs:

• /0001 { /glob "*" /type "deny" } means that by default, all query parameters are ignored (not cached).
• /0002 { /glob "search" /type "allow" } specifically allows caching for URLs with the 'search' parameter.
• /0003 { /glob "order" /type "allow" } specifically allows caching for URLs with the 'order' parameter.

Based on this, let's evaluate the options:

A. /myproduct/myrecipe.html?search=searchparam — This URL will not be cached because the 'search' parameter is allowed, but the actual value 'searchparam' does not match any allow pattern. B. /myproduct/myrecipe.html?search=s&order=asc&brand=ad — This URL will not be cached because although 'search' and 'order' parameters are allowed, the 'brand' parameter is not allowed according to the configuration. C./myproduct/myrecipe.html?brand=mybrand — This URL will be cached because there are no allowed parameters, so the default deny does not apply, and the page can be cached without considering the 'brand' parameter.

Therefore, the page that will be cached on the dispatcher is the one in option C, as it does not contain any of the explicitly allowed query parameters ('search' or 'order'), and all other parameters are ignored by default.

In Sling Models, the@DefaultInjectionStrategyannotation is used to specify the strategy for injecting fields into the model. When setting it toDefaultInjectionStrategy.OPTIONAL, it indicates that all injected fields in the Sling Model are optional and the model will not fail to instantiate if a field cannot be injected. This is a class-level annotation that affects the default injection behavior of all fields within the Sling Model.

• Option B is incorrect becauserequiredInjectionStrategyis not a valid annotation property in Sling Models.
• Option C is incorrect becauseinjectionStrategyis not specified at the class level; it is used on the field level with the@Injectannotation.
