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 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.

When an AEM instance starts with specified run modes, it selects configurations from the repository that match those run modes. Run modes allow for flexible management of settings and configurations across different environments. For the instance started with 'author', 'dev', and 'emea' run modes, it would apply configurations from paths that match these run modes.

Option B,/config/author.dev.emea.noldap, is correct. This path matches all three run modes specified and would, therefore, be included.

Option D,/apps/mysite/config.author.emea.dev, is also correct. This path matches the run modes and would be applied to the instance as well.

Options A and C do not match all three run modes and therefore would not be applied.

In Sling Models, annotations are used to map request parameters, attributes, and properties to fields in Java classes. When an HTL script passes parameters to a Sling Model, the Sling Model can use annotations to access these parameters.

• Option B uses the@RequestAttributeannotation which allows the Sling Model to retrieve an attribute that has been set on the Sling HTTP request object. This is a valid approach to read the 'testParam' if it has been set as a request attribute.
• Option C uses the@Injectannotation with thenameattribute specifying the name of the parameter to inject. This is another valid approach to read the 'testParam' from the request.
• Option A is incorrect because@Namedis not the correct annotation for retrieving request attributes or parameters.
• Option D is incorrect because there is no@Propannotation in Sling Models; it's likely confused with the@Propertyannotation which is not the correct one for this context either.

In AEM, OSGi configurations are typically managed within theui.appsMaven module. This module is responsible for the application code that comprises the components, templates, and OSGi configurations among other things. By placing OSGi configurations within theui.appsmodule, a developer can ensure that these configurations are deployed to the JCR repository and become part of the application package.

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.

In an AEM Single Page Application (SPA) project, the.model.jsonendpoint is used to expose the properties of a Sling Model as JSON. This is useful for SPAs that need to access component properties dynamically. The front-end developer should check the URL[homepage-path]/model.jsonto see the JSON output of the Sling Model for the new component. This endpoint provides a tree of the page content as JSON, which includes the Sling Model's exported properties for components included on the page.
