NO.39 A developer creates a custom component. The component dialog includes the following two fields:

he component should display the first ‘X’ characters of the text entered in the ‘text’ input where ‘X’ is the number entered in the ‘charLimit’ input. If zero, or no value, is entered in the ‘charLimit’ input then the text should be unaltered. The developer creates the following Sling Model to perform the trancation:

A Null Pointer Exception occurs if NO charLimit values is set in the component dialog.
What should the developer do to resolve this issue?

Replace the defaultValue=”0″ attribute of the ‘charLimit’ field in the dialog with min=”0″.

Add the @Default annotation to the ‘chatLimit’ variable in the Sling Model.

Replace the defaultValue=”0″ attribute of the charLimit field in the dialog with defaultValue=”{Long}0″.

Change the defaultInjectionStrategy of the Truncation Sling Model to DefaultInjectionStrategy.REQUIRED.

NO.40 How should a developer configure the replication agent to flush the dispatcher cache for a newly activated page?

NO.41 A developer is working with the following HTL expression in a component rendering script:
${‘path/page.infinity.json’ @extension = ‘html’,
removeSelectors = [‘foo’],
selectors = [‘foo’, ‘bar’],
prependSuffix = ‘hello’,
suffix = ‘world’ }
What is the expected output of this expression?

NO.42 A developer created an editable template with a Layout Container. The developer needs to restrict the Layout Container to just one column layout.
What should the developer do to the editable template to enforce this restriction?

Add responsive column control component to the template and set column type to 1

Overlay wcm.foundation.components.page.responsive Client Library and set @max_col to 1

Using Template Editor, lock the Structure Component for the template

Using Template Editor, set the responsive settings to 1 column for Layout Container Policy

NO.43 Too many pages are invalidated in the dispatcher cache when a page is published.
What is most likely causing this issue in the dispatcher configuration?

Sticky session are NOT configured properly, resulting in requests being delivered to the wrong server.

The level of cache invalidation is NOT appropriate for the published content model.

File globbing in the dispatcher configuration is NOT correct.

The OS file system permissions are NOT properly configured.

NO.44 A custom AEM application contains a service component that needs to access the JCR repository within the activate method. The activate method uses ResourceResolverFactory.getServiceResourceResolver(…) without specifying a sub service name.
What should a developer do to make sure the user service mapping for the service component is available?

Create a field of type ServiceUserMapper and annotate it with @Reference using ReferencePolicy.STATIC

Wait for the service ServiceUserMapper via BundleContext.getServiceReference(…)

Create a field of type ServiceUserMapped and annotate it with @Reference using ReferencePolicy.DYNAMIC

Create a field of type ServiceUserMapped and annotate it with @Reference

NO.45 The structure section of an editable template has a locked component.
What happens to the content of that component when a developer unlocks it?

The content stays in the same place but it ignored on pages using the template.

The content is deleted after confirmation from the template author.

The content is moved to the initial section of the editable template.

The content is copied to the initial section of the editable template.

NO.46 A developer needs to create a banner component. This component shows an image across the full width of the page. A title is shown on top of the image. This text can be aligned to the left, middle, or right. The core components feature a teaser component which matches almost all requirements, but not all.
What is the most maintainable way for the developer to implement these requirements?

Use and configure the teaser core component.

Create a new custom component from scratch.

Overlay the teaser core component.

Inherit from the teaser core component.

NO.47 A developer creates a template-type for building editable templates.
The resulting editable templates and pages must always contain a specific layout container that can NOT be deleted by the author.
How should the developer meet this requirement?

Add the layout container component to the structure section of the template-type

Add the layout container component by including it on the actual page component

Add a content policy to the template-type to disable the removal of the layout container

Add the layout container component to the initial section of the template-type

NO.48 A developer creates a Sling Servlet. The Sling Servlet is bound to a path (/service/sling/sample). Refer to the resulting code below.

@SlingServletPaths(value = {“/service/sling/sample”})
What should the developer do to make the servlet access controlled using the default ACLs?

Add @SlingServletPrefix (value = “/apps”) annotation

Use @SlingServletResourceTypes instead of @SlingServletPaths

Modify @SlingServletPaths(value = {“/bin/sling/sample”})

Add @SlingServletName(servletName = “AccessControlServlet”) annotation

NO.49 A developer identifies that some requests for the page /content/sampleproject/page.html take longer than other requests for the same page.

NO.52 A developer developed a workflow that makes a copy of every node created or modified under a certain path to a different one. The workflow launches but the nodes are not copied over.
Which two methods should the developer use to resolve this issue? (Choose two.)

Go to Workflow Failures screen and check if any instances of the workflow are present.

Go to Workflow instances screen and verify that the instance of the workflow is present and check its status.

Go to Package Manager screen and reinstall the bundle that contains the workflow so it restarts.

Go to Workflow Models screen, then delete and recreate the workflow.

Go to Workflow Launchers and create a new launcher for the workflow even if one already exists.

NO.53 A developer needs to change the label “Sites” in the navigation of AEM author to “Websites”.

NO.54 An application runs specific license checks against certain DAM assets every day. It should send an email to a configured list if it finds warnings, and mark the asset accordingly. A service component that uses the Apache Sling Scheduler Service is created. DAM assets that must NOT be used anymore are hidden using ACLs and the license check must re-check them.
How should a developer obtain a resource resolver that can read and update the DAM assets?

Set up a cron job with curl calls with the admin user and use request.getResourse().getResourceResolver().

Create a configuration line in PID com.day.cq.security.ACLSetup for the user that you obtain a session for via ResourceResolverFactory.getResourceResolver(…).

Configure the user admin in PID org.apache.sling.serviceusermapping.impl.ServiceUserMapperImpl as user.default and make sure the service user exists and has jcr:read and jcr:write permissions.

Create a configuration for PID org.apache.sling.serviceusermapping.impl.ServiceUserMapperImpl.amended-damaccess that references a pre-created service user with r/w permissions and use ResourceResolverFactory.getServiceResourceResolver(…).

NO.55 A developer needs to implement a service component that should be manually configured by operations to react on operational circumstances. The service component should NOT be active by default. The service has the properties myservice.name (one string value) and myservice.stringValues (a list of the string values) to be configured.
The developer needs to use OSGi Metatype annotations to make those properties configurable in the Apache Felix Web Console.
Which set of steps should the developer take to meet these requirements?

1. For the class fields myserviceName and myserviceStringValues, add a @AttributeDefinition annotation each with names set to myservice.name and myservice.stringValues respectively.2. Use the @Component annotation with configurationFactory = true on the service component class.3. Use the @Service service component class.4. Use the activate method of the service component class to get the configuration annotation interface class injected.

1. Create an annotation interface as inner class of the service component and annotate it with @ObjectClassDefinition.2. Apply @AttributeDefinition for the methods myservice.name and myservice.stringValues.3. Use the @Component annotation with configurationPolicy = ConfigurationPolicy.REQUIRE on the service component.4. Use the @Designate annotation to link the service component to the created configuration annotation interface.5. Use the activate method of the service component class to get the configuration annotation interface class injected.

com.custom.package.a is already installed and active in the system and has the following package definition:

The system console shows the following package availability:

Bundle com.custom.package.b to be installed has the following package definition:

What will happen when the developer uploads the bundle com.custom.package.b into the system?

The bundle will install but fail the activation due to unsatisfied dependencies com.sample.package.b and com.sample.package.c.

The bundle will install but fail the activation due to unsatisfied dependency com.sample.package.c.

The bundle will install and activate successfully.

The bundle will install but fail the activation due to unsatisfied dependency com.sample.package.b.

A developer uses the following:

What is the resulting HTML?

Option A

Option B

Option C

Option D

NO.58 A developer needs to implement a header component for a website. The component has the following requirements:
– The component should be configured once on the page highest in the hierarchy.
– The header component on pages lower in the hierarchy should look the same and show the same data.
– If necessary, the configuration can be overwritten on a child page.
– The component should show a list of links that are configured in the header component.
Which code snippet for returning the list of pages should the developer use?

“public String[] getHeaderLinks(Page page) {
final Resource pageContent = page.getContentResource();
final ComponentInheritanceValueMap properties = ComponentInheritanceValueMap(pageContent); return properties.get(HEADER_PAGE_LIST, String[].class);
}”

“public String[] getHeaderLinks(Resource componentResource) {
final ComponentInheritanceValueMap properties = componentResource.adaptTo(ComponentInheritanceValueMap.class); return properties.getInherited(HEADER_PAGE_LIST, String[].class);
}”

“public String[] getHeaderLinks(Resource componentResource) {
final HierarchyNodeInheritanceValueMap properties = new HierarchyNodeInheritanceValueMap (componentResource); return properties.getInherited(HEADER_PAGE_LIST, String[].class);
}”

“public String[] getHeaderLinks(Resource componentResource) {
final HierarchyNodeInheritanceVauleMap properties = componentResource.adaptTo(HierarchyNodeInheritanceVauleMap.class); return properties.getInherited(HEADER_PAGE_LIST, String[].class);
}”

NO.59 A developer is working on a complex project with multiple bundles. One bundle provides an OSGi service for other bundles.
Which two options are necessary to ensure that the other bundles can reference that OSGi service? (Choose two.)

The bundles consuming the service need to import the fully qualified name of the service interface.

The bundle providing the service needs to contain an adequate SCR descriptor file.

The bundle providing the service needs to export the java package of the service interface.

The bundle providing the service needs to contain a whitelist of allowed consumer bundles.

The service needs to correctly declare metatype information.

NO.60 The following stack trace is written in the error.log file after installing a custom application package.
Could not start bundle com.adobe.cq.sample-bundle [526]. Reason: {}. Will retry.
org.osgi.framework.BundleException: Unable to resolve com.adobe.cq.sample-bundle [526](R 526.0): missing requirement [com.adobe.cq.sample-bundle] osgi.wiring.package What are two different ways that the developer could resolve the OSGi bundle dependency error? (Choose two)

Go to the Dependency Finder in the System Console to find if another bundle is exporting a similar version of the classes and change the project pom.xml to match the same version

Install the jar in AEM via the curl command ‘curl -u username:password -F file=@”./com.example.customlib-3.8.jar” -F name=”Dependency” -F force=true -F install=true http://localhost:4502/crx/packmgr/service.jsp –progress-bar -o upload.txt’

Create a folder named “deploy” under $AEM_HOME/crx-quickstart/ and copy com.example.customlib-3.8.jar in there so AEM uploads it automatically

Go to the project parent pom.xml file and add the dependency with the scope “compile” and instruct the bundle plugin to include the dependency in runtime

Upload the file com.example.customlib-3.8.jar into /apps/<project>/libs folder in CRX DE to make it available for the OSGi bundle

NO.61 A developer has a component located under the path /apps. This component has a Client Library which is directly loaded onto a page. The publish instance loads the page correctly. The dispatcher also loads the page but the Client Library is missing.
How should the developer resolve this issue, while taking security into consideration?

Change the ACLs for the Client Library.

Move the Client Library under /apps/<project>library.

Add the property allowProxy with a boolean value true.

Allow the path to the clientlibs on the dispatcher.
