質問 # 40
A developer wants to view response times for page transactions.
Which log file should they use?
正解：C
解説：
Comprehensive Explanation
Adobe Experience Manager maintains an HTTP request log that records incoming requests and their corresponding responses, including response times.
The request.log file is particularly useful for identifying slow page requests, diagnosing performance problems, and evaluating application responsiveness.
Each request receives an identifier that associates the incoming HTTP request with its corresponding response. The response record includes the HTTP status code, content type, and processing time.
For example:
09:43:41 [66] - > GET /content/site/en.html HTTP/1.1
09:43:41 [66] < - 200 text/html 797ms
In this example, AEM required 797 milliseconds to process the request.
Option A is incorrect because audit.log primarily records auditing information, such as content-related administrative and moderation activities.
Option B is incorrect because stdout.log captures standard-output messages, including startup-related information, rather than providing the dedicated request timing records.
Option C is correct because request.log provides a direct mechanism for analyzing HTTP response times.
Adobe recommends using request-log analysis to identify slow pages, evaluate request concurrency, and diagnose application performance bottlenecks.
For extensive performance investigations, developers can aggregate response times by URL and correlate slow requests with thread dumps, repository query performance, and application logs.

質問 # 41
A developer needs to render 'Hello World' only when in edit mode.
Which approach should be used?
正解：C
解説：
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.

質問 # 42
How does a developer configure replication between the Author and Publish instances in an AEM Author- Publish topology?
正解：C
解説：
Comprehensive Explanation
In the traditional Adobe Experience Manager Author-Publish topology, replication agents manage the publication of content from the Author environment to one or more Publish environments.
A replication agent is configured on the Author instance with the appropriate transport URI, authentication credentials, and replication settings.
When an author activates content, AEM sends a publication request to the configured replication agent. The agent packages the relevant repository content, places the request in its replication queue, and transmits the content to the designated Publish instance.
A receiving servlet on the Publish instance processes the incoming request and installs the replicated content.
Option A is incorrect because workflows may initiate publication operations but are not themselves the underlying transport mechanism responsible for replication.
Option B is incorrect because although OSGi services participate in replication functionality, creating an arbitrary custom OSGi configuration is not the standard procedure for establishing Author-to-Publish replication.
Option D is incorrect because Dispatcher provides caching, request filtering, and load-balancing functionality rather than acting as the primary content-replication mechanism.
Version distinction: AEM as a Cloud Service uses a managed content-distribution architecture. Traditional replication-agent configuration remains relevant for AEM 6.5 and Adobe Managed Services environments.

質問 # 43
A developer needs to determine whether a publication is pending or blocked.
Where can this information be located?
正解：B
解説：
Comprehensive Explanation
Adobe Experience Manager provides Replication Agent Status information for monitoring publication requests and identifying replication-queue problems.
In AEM 6.5, developers and administrators can inspect replication agents through the Replication console, available from the Author environment.
Each replication agent exposes configuration details, operational status, queue information, and relevant diagnostic information.
Adobe documents several replication-queue states, including Active, Idle, and Blocked.
An Active queue is processing replication requests. An Idle queue contains no outstanding requests. A Blocked queue contains requests that cannot currently be processed, potentially because the receiving Publish instance is unavailable, network connectivity has failed, or transport authentication is unsuccessful.
The replication queue also identifies pending requests, enabling administrators to determine which content has not yet completed publication.
Option B is incorrect because publish.log is not the standard AEM location for determining replication-agent queue status.
Option C is plausible because replication logging can provide useful diagnostic information. However, the agent's queue-status interface is the more direct location for determining whether publication requests are pending or blocked.
Option D is incorrect because Dispatcher-related status information concerns caching and request delivery rather than the Author-to-Publish publication queue.
Adobe recommends inspecting replication-agent queues when diagnosing failed or delayed publication operations.

質問 # 44
A developer must remove all selectors from linkValue.
Assuming linkValue = 'path/page.woo.foo.html', which two HTL approaches would be used to accomplish this task?
Choose two
正解：C
解説：
Comprehensive Explanation
Content Fragments provide a centralized, reusable mechanism for managing structured, presentation- independent content across multiple delivery channels in Adobe Experience Manager.
In the described scenario, a product description must be maintained consistently across a website, mobile application, and email campaign. A Content Fragment allows the marketing team to manage this information independently of the design and layout requirements of each destination.
Content Fragments are based on Content Fragment Models, which define structured fields such as product names, descriptions, specifications, and associated references.
Each consuming channel controls how the content is presented. A website might render the description through an AEM component, while a mobile application retrieves it through an appropriate headless delivery API.
Option A does not identify the standard AEM feature for reusable structured content. Option B is similarly not the appropriate content-management construct.
Option D refers to Experience Fragments, which are intended for reusable experiences that include presentation and layout. They are particularly suitable for reusable banners, promotional sections, and visually structured campaign content.
For centrally maintained product descriptions that must be reused across multiple channels, the presentation- agnostic architecture of Content Fragments is more appropriate.
