AEM Development
11 questions in this domain
- Question 1Single Choice
What is the purpose of the sling:resourceSuperType property in a proxy component?
- ADefines the resource type for rendering
- BPoints to a parent component to inherit behaviorCorrect answer
- CSets the default category for client libraries
- DStores the component's dialog definition
Why this is the answer
The sling:resourceSuperType sets the parent component for inheritance, enabling the proxy pattern without copying resource types.
- Question 2Multiple Select
Which annotations are valid for creating a Sling Model? (Select two)
- A@ModelCorrect answer
- B@SlingServlet
- C@InjectCorrect answer
- D@Component
Why this is the answer
@Model marks the class as a Sling Model; @Inject is used for dependency injection into the model.
- Question 3Interactive

- AIncludes a client-side JavaScript library
- BLoads a Java Use-API object and makes it available in the templateCorrect answer
- CApplies a CSS class to the element
- DDefines a reusable template fragment
Why this is the answer
data-sly-use instantiates a server-side Java or JavaScript object, exposing its methods and properties to the HTL template.
- Question 4Single Choice
Where are editable template policies stored in the AEM repository?
- A/apps/
- B/content/
- C/conf/Correct answer
- D/etc/designs/
Why this is the answer
Editable template policies are stored under /conf/<project>/settings/wcm/policies/.
- Question 5Multiple Select
Which properties must be set for a client library folder under /apps to be served via the proxy path? (Select two)
- AallowProxy = trueCorrect answer
- BcategoriesCorrect answer
- Cjcr:primaryType = cq:ClientLibraryFolder
- Ddependencies
Why this is the answer
allowProxy=true enables the proxy path; categories is needed for the clientlib to be included by components.
- Question 6Interactive
Refer to the overlay path: /apps/project/components/text. What does the Sling Resource Merger do when a component requests a resource from /libs?
- AIt only looks in /libs, ignoring the overlay.
- BIt merges properties from both, with /apps taking precedence.Correct answer
- CIt replaces /libs entirely with the overlay.
- DIt throws an error if both paths exist.
Why this is the answer
The Sling Resource Merger checks /apps first; if nodes exist, they override /libs. Non-overridden parts fall back to /libs.
- Question 7Single Choice
Which interface must a custom workflow step implement?
- AWorkflowProcessCorrect answer
- BJobConsumer
- CEventHandler
- DSlingSafeMethodsServlet
Why this is the answer
Custom workflow steps must implement the com.adobe.granite.workflow.exec.WorkflowProcess interface.
- Question 8Multiple Select
Which two statements are true about AEM tags? (Select two)
- ATags are stored as cq:Tag nodes under /content/cq:tags.Correct answer
- BTags must be created using the TagManager API.Correct answer
- CTags are automatically inherited by child pages.
- DThe cq:tags property stores a single string value.
Why this is the answer
Tags reside under /content/cq:tags (or legacy /etc/tags) and are created via TagManager. They are not inherited and cq:tags is a string array.
- Question 9Interactive
Given this client-side custom event creation: new CustomEvent('aem:filterupdate', { detail: { key: 'color', value: 'red' } }). What is the correct way to listen for this event?
- Adocument.addEventListener('aem:filterupdate', handler)Correct answer
- BaddEventListener('CustomEvent', handler)
- CEventAdmin.onEvent('aem:filterupdate', handler)
- Dwindow.on('customEvent', handler)
Why this is the answer
CustomEvent creates a named event; to listen, use standard DOM addEventListener on the document or element with the same event name.
- Question 10Single Choice
What is the primary advantage of using a Job over an Event for long-running tasks?
- AJobs provide reliable, persistent execution with retries.Correct answer
- BEvents are more secure and require less configuration.
- CJobs can only run on publish instances.
- DEvents support parallel execution by default.
Why this is the answer
Jobs are persisted in the repository and can be retried, making them suitable for long-running or unreliable operations.
- Question 11Multiple Select
Which two patterns enable cross-component communication on the client side? (Select two)
- AUsing CustomEvent with addEventListenerCorrect answer
- BSetting window.globalState variable
- CUsing a shared event bus like EventEmitterCorrect answer
- DDirectly calling methods on other components
Why this is the answer
CustomEvent and a dedicated event bus decouple components; global variables and direct method calls create tight coupling.

- AUse resource bundles placed under /apps/.../i18nCorrect answer
- BUse the Translation Integration Framework (TIF)

- Question 18Single Choice
What node type is used to store OSGi configurations in the AEM JCR repository?
- Asling:OsgiConfigCorrect answer

Given the following Query Builder predicate map, what does the query return? The snippet uses the 'property' predicate with 'operation=like'.
- AAll pages under /content that have a title starting with 'About'Correct answer
- BAll pages under /content with a title exactly equal to 'About'
- CAll resources under /content with a description containing 'About'
- DAll resources under /content that do not have a title
Why this is the answer
The predicate 'property.operation=like' performs a prefix match, so it retrieves nodes where the property starts with the given value.

- A/apps/myprojectCorrect answer
- B/apps/myproject/components
- C/apps
- D/apps/myproject/config
Why this is the answer
The filter's root path is '/apps/myproject', and no sub-path excludes it, so the entire subtree under that path is included.

In Multi-Site Manager (MSM), what is the direction of content inheritance?
- AFrom live copy to blueprint
- BFrom blueprint to live copyCorrect answer
- CBidirectional between blueprint and live copy
