NEW QUESTION # 27
A content author will be using live copies on AEM.
Which two factors must the content author now consider? (Choose two.)
- A. When the inheritance Is re-enabled, the page is automatically synchronized with the source.
- B. When (everting a canceled inheritance on a paragraph system, the order of components will be automatically restored from the blueprint.
- C. Changes made locally to a component marked as a container will not be overwritten by the content of the blueprint on a rollout.
- D. If the component is marked as a container, the cancellation and suspend actions do not apply to Its child components.
Answer: A,C
Explanation:
In Adobe Experience Manager (AEM), when dealing with live copies, a content author must be aware of various factors related to the synchronization of content between the source (blueprint) and the live copies.
Option A is correct because when inheritance is re-enabled on a live copy page, synchronization with the blueprint page occurs, which may include automatic updates to the live copy page's content. Option D is also correct because local changes made to a component marked as a container are protected during rollouts, meaning that these local changes will not be overwritten by content from the blueprint. The container concept in AEM allows for more granular control over which parts of the page are updated during synchronization.
For Option B, the term 'paragraph system' seems incorrect. It should likely refer to 'paragraph systems' as in the ParSys (Paragraph System), a component that allows authors to add components to a page. There is no automatic restoration of the order of components from the blueprint upon re-enabling canceled inheritance; instead, components are managed according to the rules set in the rollout configurations.
Option C is incorrect because the cancel and suspend actions can be applied to individual child components within a container. When inheritance is canceled for acontainer, the inheritance status of child components within that container can be controlled individually.
NEW QUESTION # 28
A developer has to allow third-party applications to access the content of the Experience Fragment directly, using only the URL. It should be available through the browser.
Which selector would be used for this purpose?
- A. noCss
- B. plain
- C. text
Answer: C
Explanation:
When it comes to rendering the content of an Experience Fragment for third-party applications to access directly via a URL, and in a browser-friendly format, thetextselector is used. This selector causes AEM to render the Experience Fragment as plain text, which is typically what a third-party application would require if it needs to consume the content directly without any associated styling or scripts.
Option B,noCss, is not a standard selector for this purpose.
Option C,plain, is not the correct selector for rendering Experience Fragment content in AEM. Theplain selector might suggest a text/plain MIME type, but in AEM, the correct selector for retrieving the text content of an Experience Fragment istext.
NEW QUESTION # 29
Multiple Experience fragments have been created as a part of the ongoing AEM Project. These Experience fragments can be exported to Adobe Target using the "Export to Adobe Target" configuration and by providing Cloud Configuration for Adobe Target.
What is the default format used to complete this export?
- A. HTML
- B. JSON
- C. XML
Answer: A
Explanation:
Experience Fragments in AEM can be exported to Adobe Target, and the default format for this export is HTML. When Experience Fragments are exported to Adobe Target, they are typically used for personalization and A/B testing. HTML is the format that is readily usable within Adobe Target to create variations of a page or a component for these testing purposes.
XML (Option B) and JSON (Option C) are not the default formats for exporting Experience Fragments to Adobe Target. While they can represent structured data, for the purposes of visual personalization in Adobe Target, the HTML format is used because it can directly represent the markup required for the content to be rendered in a browser.
NEW QUESTION # 30
A developer wants to write a Java service that will serve some data to the custom component.
Which one of the Maven modules is the place to create this service?
- A. core
- B. ui.apps
- C. uicontent
Answer: A
Explanation:
A Java service, which is a backend Java class that encapsulates some business logic or functionality, should be placed in thecoreMaven module of an AEM project. This module is intended for the Java code that contains OSGi services, servlets, and other Java backend code. By creating the service in thecoremodule, it can be properly compiled, packaged, and deployed as an OSGi bundle within AEM.
NEW QUESTION # 31
In an AEM as a Cloud Service environment, a client needs a feature to be able to explicitly clear a dispatcher cache of required resources.
Which approach is preferred to create this feature?
- A. Use Replication API along with replication flush agent.
- B. Create a servlet, which will make an HTTP request to the dispatcher.
- C. Enable the explicit cache invalidation feature in cloud manager.
Answer: A
Explanation:
In an AEM as a Cloud Service environment, the preferred approach to clear dispatcher cache of required resources is to use the Replication API along with a replication flush agent. This method allows for programmatic clearing of the cache and is the standard way of invalidating cached content so that the dispatcher can retrieve fresh content from the publish instance.
Option A, "Enable the explicit cache invalidation feature in cloud manager," is not a standard feature available in Cloud Manager.
Option C, "Create a servlet, which will make an HTTP request to the dispatcher," is not advisable as it bypasses the recommended AEM replication and flushing mechanisms and could lead to inconsistencies.
NEW QUESTION # 32
A developer wants to be able to execute the following query:
SELECT
* FROM [ntbase] AS s
WHERE
s.status ='STARTED'
Which two options are mandatory additions to the Index? (Choose two.)
- A. status property with propertylndex = true
- B. ntbase aggregate
- C. status properly with property Index = false
- D. ntbase index rule
Answer: A,D
Explanation:
When creating a custom query in AEM's JCR (Java Content Repository), the query's performance is highly dependent on the indexing configuration. For the given query that selects all nodes with a 'status' property equal to 'STARTED' from the 'nt:base' node type, the index must be set up correctly:
Option A, "nt:base index rule", is correct. The index rule for 'nt:base' must be added to define which properties of nodes of this type are indexed.
Option D, "status property with propertyIndex = true", is also correct. This index ensures that queries filtering on the 'status' property are executed efficiently. The property index should be set to true, which means that this property is indexed and the query will use this index to filter the results.
Option B is incorrect because setting the property index to false would mean that the property is not indexed, making the query less efficient since the repository would need to scan each node to find matches.
Option C, "nt:base aggregate", is not mandatory. Aggregates are used to include properties of related nodes in the index, but they are not required for a simple property match like the one in the given query.
NEW QUESTION # 33
Which service is used in AEM to control how AEM instances interact with a topology, while running on instances?
- A. Web Console Service
- B. Offloading Service
- C. Apache Sling Resource-Based Service
Answer: C
Explanation:
The service used in AEM to control how AEM instances interact with a topology while running on instances is the Apache Sling Resource-Based service. This service helps in managing the resources and how they're resolved and accessed within the AEM topology. It's part of the Apache Sling framework, which is an integral part of AEM's architecture.
Option A, "Web Console Service," is more for administration and management of OSGi components, not specifically for topology interaction.
Option C, "Offloading Service," is generally related to processing tasks outside of the AEM instances and does not directly control instance interactions within a topology.
NEW QUESTION # 34
While configuring a Content Fragment Component, the author has selected 'Display Mode' as 'Single Text Element'. This enables the selection of one multiline text element and enables paragraph control options.
Which two properties will now determine the resulting action? (Choose two.)
- A. Paragraph Range
- B. Paragraph Description
- C. Paragraph Scope
- D. Paragraph Heading
Answer: A,C
Explanation:
When the 'Display Mode' is set to 'Single Text Element' in the configuration of a Content Fragment Component in AEM, the properties that will determine the resulting action are related to how the text is displayed and managed in terms of paragraphs.
C: Paragraph Range - This property would determine the range of paragraphs to display from the multiline text element.
D: Paragraph Scope - This property would define the scope of the paragraph, such as whether all paragraphs are included or just a specific subset.
Options A (Paragraph Description) and B (Paragraph Heading) are not directly related to the action of displaying a single text element with paragraph control.
NEW QUESTION # 35
Given this configuration property:
Which page will be cached on the dispatcher?
- A. /myproduct/myrecipe. html?brand=mybrand
- B. /myproduct/myrecipe. htmI'search=searchparam
- C. /myproduct/myrecipe. html?search- s&ordet=asc&brand=ad
Answer: A
Explanation:
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.
NEW QUESTION # 36
A developer is starting an AEM instance every time in the debug mode by providing JVM parameters in the console. The developer needs to automate this process to avoid adding JVM parameters at every start of an AEM instance.
How would the developer accomplish this goal?
- A. By adding JVM parameters to the start script
- B. By setting the OSGi configuration "AEM-start' to true
- C. By adding JVM parameters to the [runmode]/crx-quickstart/conf/quickstart.properties
Answer: A
Explanation:
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) or start.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.
NEW QUESTION # 37
Which default timing card is available when the Automated Maintenance Tasks are being accessed at serveraddress:port/libs/granite/operations/content/maintenance.html?
- A. Monthly Maintenance Window
- B. Quarterly Maintenance Window
- C. Daily Maintenance Window
Answer: C
Explanation:
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.
NEW QUESTION # 38
A developer wants to overwrite an OSGi configuration via the codebase.
Which one of the Maven modules is the place to create this configuration on the codebase?
- A. core
- B. ui.apps
- C. ui.content
Answer: B
Explanation:
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.
NEW QUESTION # 39
Which two methods are used to update the cache? (Choose two.)
- A. Restart on AEM Publish Instance
- B. Content Updates
- C. Restart on AEM Author Instance
- D. Auto-invalidation on the Dispatcher
Answer: B,D
Explanation:
Updating the cache in AEM is critical to ensure that users receive the most current content without unnecessary delays. Two common methods used to update the cache include:
A: Content Updates - Content updates can trigger an invalidation or flush of the cache. When content is published or updated on the AEM author instance and replicated to the publish instance, the dispatcher cache can be set to automatically invalidate the affected pages. This ensures that the next request to these pages serves the latest content.
D: Auto-invalidation on the Dispatcher - The dispatcher can be configured to automatically invalidate cached content under certain conditions, such as when a TTL (Time To Live) expires or when specific actions occur, such as a page activation ordeactivation. This is often preferred to manual cache clearing as it can be more efficient and targeted to the specific content that has changed.
Options B and C are incorrect because restarting the AEM Author or Publish instances does not directly relate to cache update methods. These actions are more associated with system maintenance or updates and would not be standard practice for updating cached content.
NEW QUESTION # 40
Which offloading-related service is used by each AEM instance to connect to AEM Topology Connector?
- A. Discovery Service
- B. Cluster Service
- C. Topology Connector Service
Answer: A
Explanation:
The Discovery Service is an offloading-related service used by each AEM instance to connect to AEM Topology Connector. The Discovery Service is part of the Sling Discovery framework, which is responsible for detecting and managing the topology of AEM instances. It enables instances to discover each other and establish a clustered topology, which is essential for load-balancing, failover, and other distributed operations.
Option A, "Cluster Service," is not a standard term used in AEM for connecting to the Topology Connector.
Option C, "Topology Connector Service," is a slightly misleading term; the correct term is Discovery Service, which performs the role described.
NEW QUESTION # 41
An AEM sites developer is working on the development of a 'Hello World' component and wants to facilitate the mapping of data from the JCR to Java variables.
Which feature should the developer use to provide this facilitation?
- A. Sling Models
- B. HTL and Dialogs
- C. Client-Side Libraries
Answer: A
Explanation:
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.
