Comprehensive Explanation

Adobe Experience Manager provides the wcmmode object within HTL to identify the current Web Content Management rendering mode.

The wcmmode.edit property evaluates to true when a page is rendered in AEM's Edit mode. This enables developers to conditionally display authoring-specific markup without including that markup in normal published-page output.

The data-sly-test block statement evaluates a Boolean expression and renders its host element only when the expression is true.

The correct implementation is:

< p data-sly-test="${wcmmode.edit}" >

Hello World

< /p >

When an author opens the page in Edit mode, the paragraph is rendered. In other modes where wcmmode.edit evaluates to false, the paragraph is omitted.

Option A is incorrect because wcm.edit is not the documented HTL property for detecting the current authoring mode.

Option B is incorrect because wcmmode.editor is not the recognized mode property.

Adobe also documents wcmmode.preview for conditions that must apply specifically to Preview mode.

A common practical application involves displaying component placeholders when a component has no configured content. Such placeholders help authors identify and select components that would otherwise appear empty.

The wcmmode.edit condition is therefore the correct mechanism for rendering content exclusively in Edit mode.

Comprehensive Explanation

The exhibit contains a JCR-SQL2 query that selects repository nodes of type nt:base where the status property equals STARTED .

To support this query efficiently through a Lucene index, the index definition must include an applicable node-type rule and a property definition capable of evaluating the equality restriction.

Option D provides the required nt:base index rule. Because the query operates against nt:base , the index must support the relevant node types rather than restricting its definition to an incompatible resource type.

Option C enables property indexing for status by setting propertyIndex=true . This tells the Lucene index to maintain property values suitable for query constraints such as equality comparisons.

Option A is incorrect because propertyIndex=false does not enable the required property-based lookup.

Option B is incorrect because aggregation is used principally to incorporate child-node content into a parent node's index representation, especially for full-text scenarios. It is not required for this direct property comparison.

An appropriately defined Lucene index can therefore support the query using the nt:base index rule and the indexed status property.

Implementation note: These are the necessary additions among the supplied choices, assuming a suitable Lucene index already exists. The complete index also needs appropriate index-definition properties, and production indexing should avoid unnecessarily broad repository scans.

Comprehensive Explanation

The Adobe AEM Project Archetype supports the package parameter for defining the Java source package used when generating the project structure.

According to the official archetype properties, the package parameter defaults to the value of groupId .

For example:

-DgroupId=com.example

-Dpackage=com.example.aem.core

In this configuration, groupId controls the Maven project group identifier, while package explicitly specifies the Java package namespace.

This distinction is important when an organization wants its generated Java classes to use a package structure different from its Maven artifact coordinates.

Option B is incorrect because packageManager is not the relevant archetype generation property.

Option C is incorrect because basePackage is not the property documented in the official Adobe AEM Project Archetype parameter table.

Option D is a plausible distractor because groupId establishes the default Java package name when the package parameter is omitted. However, it is not the specific property used to override that package name.

The correct answer is therefore package .

Adobe's archetype documentation identifies the default value of package as ${groupId} , confirming that these properties are related but have distinct purposes.

Comprehensive Explanation

Adobe Experience Manager provides client-library debugging functionality to help developers inspect JavaScript and CSS resources included through the AEM client library system.

Client libraries frequently combine and minify multiple JavaScript and CSS files to improve production performance. This optimization can make it difficult to determine which source file contains a defective event handler.

Adobe documents the debugClientLibs=true query parameter as a mechanism for examining the underlying files embedded within client libraries.

The developer can append this parameter to the page URL:

/content/mysite/en/home.html?debugClientLibs=true

After reloading the page, the developer can inspect the generated client-library references to identify the original source files and troubleshoot the relevant JavaScript.

Option B is incorrect because examining repository configuration folders is not the most direct approach for diagnosing client-side event behavior.

Option C primarily supports debugging Adobe Experience Cloud and Experience Platform integrations rather than general component event handlers.

Option D can assist with investigating failed network requests, but it does not specifically activate AEM client-library debugging.

Qualification: Enabling debugClientLibs does not itself identify a faulty button event handler. The developer should subsequently use browser developer tools, JavaScript breakpoints, and event-listener inspection to isolate the problem.

Comprehensive Explanation

Adobe Experience Manager Multi Site Manager (MSM) enables organizations to maintain a centrally managed content source while distributing localized variations across multiple regional websites.

For this scenario, the appropriate implementation is to establish a primary French-language site and create Live Copies for Chad, Ivory Coast, and Senegal.

The primary French site serves as the content source, while individual country sites inherit common information through MSM Live Copy relationships. Rollout configurations determine when and how changes are synchronized between the source and regional destinations.

Each country can maintain localized information, including currency, shipping conditions, payment methods, promotional offers, and country-specific regulatory disclosures. Inheritance can be suspended where localized content must differ from the central version.

Option A is less appropriate because MSM does not perform language translation itself. Adobe recommends using translated language masters as sources for regional sites that share the same language.

Option C incorrectly emphasizes copying templates rather than managing Live Copies of content pages. Option D creates unnecessary duplication and weakens centralized content governance.

Using a French language master therefore provides consistent content management while preserving the flexibility required for country-specific localization.
