NEW QUESTION # 15
A developer needs to enable asynchronous indexing of multiple properties.
Which type of index should the developer use?
Answer: A
Explanation:
Comprehensive Explanation
A Lucene index is the appropriate choice for asynchronously indexing multiple properties in Adobe Experience Manager.
AEM uses Apache Jackrabbit Oak as its repository implementation. Oak supports several index types, but Lucene indexes are particularly suitable for complex queries involving multiple properties, full-text searches, and structured content filtering.
A Lucene index is defined under /oak:index with an index definition specifying its indexed properties, applicable node types, and operational settings. Asynchronous indexing can be enabled through the async property, allowing repository changes to be processed independently of the original content-writing transaction.
This architecture reduces the overhead associated with maintaining complex indexes during content modifications. However, asynchronous indexes are eventually consistent, meaning that recently committed changes may not immediately appear in query results.
Option A is unsuitable because the historical Ordered index is not the recommended mechanism for modern AEM indexing requirements. Option C refers to a Property index, which is generally appropriate for simpler property-based equality queries rather than complex asynchronous indexing.
Adobe recommends Lucene-based indexes for custom indexing requirements, with carefully defined index rules and property definitions to maintain query efficiency.

NEW QUESTION # 16
A developer reviews an AEM start script on the server and finds that the CQ_JVM_OPTS parameter is set to:
"-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n"
How does this value affect startup of the AEM instance?
Answer: C
Explanation:
Comprehensive Explanation
The -agentlib:jdwp Java Virtual Machine parameter activates the Java Debug Wire Protocol (JDWP), enabling a debugger to connect to a running Java process.
In Adobe Experience Manager, this configuration is commonly used when debugging Java code through an IDE such as Eclipse or IntelliJ IDEA.
The parameter transport=dt_socket specifies socket-based communication between the JVM and debugging client.
The address=8000 setting identifies the port used for debugger connections, while server=y instructs the JVM to listen for incoming debugger connections.
The suspend=n setting is particularly important because it allows the AEM instance to continue starting without waiting for a debugger to attach.
Option A is incorrect because suspending startup would require suspend=y . Even then, startup would wait for a debugger rather than necessarily fail.
Option C is incorrect because the debug-agent settings do not determine the AEM instance's Author or Publish run mode.
Option B correctly identifies that the instance starts with remote debugging enabled.
Technical distinction: Remote JVM debugging is different from setting the AEM application log level to DEBUG . The JDWP parameter enables debugger attachment, breakpoints, and Java execution inspection.
Adobe recommends avoiding unnecessary remote debugging in production because it can introduce performance and security risks.

NEW QUESTION # 17
A developer finds that Dispatcher is not permitting query parameters.
Which Dispatcher configuration section should the developer review to resolve the issue?
Answer: C
Explanation:
Comprehensive Explanation
Adobe Experience Manager Dispatcher controls external HTTP request access through the /filter section of its farm configuration. This section can permit or reject requests according to their HTTP method, URL, selectors, extensions, and query strings.
When Dispatcher rejects a request containing query parameters, the developer should inspect its access-filter rules to determine whether an appropriate /query condition has been configured.
For example:
/filter {
/0001 {
/type "allow"
/method "GET"
/url "/content/site/*"
/query "q=*"
}
}
This rule permits matching GET requests containing the designated query parameter.
Option A controls the AEM rendering instances and does not determine whether query strings are permitted.
Option B generally refers to cache rules, which govern cache eligibility. Option C controls caching behavior, including /ignoreUrlParams , rather than request authorization.
Technical qualification: The actual Dispatcher configuration directive is /filter , not /filters . Therefore, option D contains a naming error.
Additionally, if the problem concerns pages with query parameters bypassing the cache rather than being rejected, option C would be relevant because /cache/ignoreUrlParams controls query-parameter caching behavior.
For requests being denied, D identifies the intended configuration area.

NEW QUESTION # 18
A developer is working with a Live Copy page that is based on a blueprint and is not configured with a rollout configuration.
What happens when it is used?
Answer: C
Explanation:
Comprehensive Explanation
Adobe Experience Manager Multi Site Manager applies a defined configuration-resolution hierarchy when determining the rollout configuration for a Live Copy.
When a Live Copy page does not explicitly define a rollout configuration, AEM checks whether its associated blueprint source page specifies one. If a configuration exists on the blueprint source, AEM applies that configuration to the Live Copy.
This behavior ensures that synchronization policies defined at the source can govern associated Live Copies without requiring every individual page to maintain a duplicate configuration.
Adobe documents the resolution order as follows: an explicit Live Copy configuration takes precedence; otherwise, the blueprint source configuration is considered. If neither specifies a configuration, AEM checks the Live Copy parent page. Finally, the system default applies when no configuration is available through the preceding levels.
Option A is incorrect because the system default is a fallback, not the immediate choice. Option C is incorrect because the absence of an explicit configuration does not automatically cause a publication error. Option D describes a later fallback condition.
Therefore, option B correctly identifies the configuration that takes precedence in the scenario.

NEW QUESTION # 19
An Adobe Experience Manager developer needs to identify issues involving client-side events associated with a UI button. The developer intends to use the client library for debugging.
What should the developer do first?
Answer: B
Explanation:
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.
