1. 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 shouldbe 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 thedefaultValue=”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.REQUIRE

2. What is not available in globel.jsp?

currentPage

currentNode

currentDesign

currentResource

3. A developer is creating templates and/or components using CRXDE Lite. The developer needs to check the files into source control.

Which tool should the developer use to achieve this goal?

vlt command

Content Explorer

http://localhost:4502/crx/checkout

mvn command

4. Adeveloper 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 controlcomponent 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

5. A developer is working on a project locally and needs to install packages manually. The deployments to the localhost must be automated to speed up development. This functionality must be toggled on and off, depending on the needs of the developer.

Which step should the developer take to achieve this?

Configure the maven install plugin by defining the target URL, username and password as maven properties.

Add a maven profile and configure the content package maven plugin within this profile

response.log

request.log

history.log

audit.log

7. After a recent code deployment, an AEM site is experiencing longer than usual query execution time. The deployment package contained some new Lucene index definitions. A developer needs to identify the long running queries and confirm that the new index definitions are getting applied correctly.

Which action should the developer take to investigate this problem?

Goto Tools > Operations > Diagnosis > Log Messages. Configure DEBUG log level on com.day.cq.search tomonitor search queries.

Goto Tools > Operations > Diagnosis > Query Performance > Slow Queries. Select a Query and Click on Explain

Goto Tools > Operations > Diagnosis > Index Manager. Select the new Indexes and run a consistency check.

Goto Tools > Operations > Diagnosis > Download Thread Dumps. Analyze the Thread Dumps to identify long running requests.

8. A developer is creating a custom component on the page /latestBlogs.html that needs to list all the titles of the blogs pages under /content/blogs.

How does this component get the list of child pages?

Instantiate a node object with session.getNode(/content/blogs) and then iterate through the child nodes and print the title for each.

Use the QueryDebugger to look for all children of /content/blogs and then iterate through the result set and print the title for each.

Adapt the resourceResolver to the PageManger service, then use the getPage(/content/blogs) to instantiate a Page object andthen iterate through the child pages and print the title for each.

Use PageManager.getPage("/content/blogs") of the static PageManager class to instantiate a Page object and then iterate through the child pages and print the title for each.

9. The developer is presented with acomponent "Component A" which inherits from a component "Component B".

The dialog of Component A on path ../cq:dialog/../../items looks like:

+ align

- jcr:primaryType="nt:unstructured"

- sling:resourceType="granite/ui/components/coral/foundation/form/select"

- fieldLabel="Align Text"

- name="./align"

The dialog of Component B on path ../cq:dialog/../../items looks like:

+ title

- jcr:primaryType="nt:unstructured"

- sling:resourceType="granite/ui/components/coral/foundation/form/textarea"

- fieldLabel="Title"

- name="./title"

+ description

- jcr:primaryType="nt:unstructured"

- sling:resourceType="granite/ui/components/coral/foundation/form/textarea"

- fieldLabel="Description"

- name="./description"

Therequirement for the dialog is that the *Align Text* field is shown after the *Title* field.

What should the developer do without changing Component B?

Move the align node from Component A to Component B and order them according the requirements.

Move allthe nodes under the item node from Component B to Component A and order them according the requirements.

Extend Component B with the functionality of Component A

Add the property sling:orderBefore="description" to the align node.

11. A custom AEM application contains Bundle A and Bundle B. Bundle A has a dependency to Bundle B via Import-Package.

How can both bundles be deployed most efficiently across all environments?

Use the Felix Web Console to upload the bundles in the correct order.

Create one content package per bundle and use a package dependency to ensure installation order.

Embed both bundles in one content package and use property ‘installationOrder’ in package properties for correct bundle installation order.

Embed both bundles in one content package: the dependency via Import-Package is enough to ensure correct installation.

12. The following stack trace is written in the error.log file after installing a custom application package.

Could not startbundle 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

/statfileslevel "2"

/rules

{

/0000 { /glob "*" /type "allow" }

}

/invalidate

{

/0000 { /glob "*" /type "deny" }

}

}

drwxr-xr-x. 3 apache apache 4096 Nov 29 16:07 ..

drw-r--r--. 4 root root 4096 Feb 7 03:21 content

-rw-r--r--. 1 apache apache 0 Feb 7 03:19 .stat

Change the value of the entry /statfileslevel to "3"

Delete the contents of the DOCROOT directory
