That's why TrainingDump offers actual Adobe AD0-E128 exam questions to help candidates pass the exam and save their resources.
NEW QUESTION # 24
In Adobe Experience Manager (AEM), while using editable templates, a developer wants to use custom components in a template with Sightly (HTL).
How can the developer do this?
Answer: B,D
Explanation:
Comprehensive Explanation
Adobe Experience Manager's HTML Template Language supports URI manipulation through expression options, including selectors , addSelectors , and removeSelectors .
The selectors option can replace the selector portion of a URI. When invoked without an assigned value, or with an explicitly empty string, it removes all selectors while preserving the resource path and extension.
For the original value path/page.woo.foo.html , the two valid HTL expressions are:
${linkValue @ selectors}
${linkValue @ selectors=''}
Both produce:
path/page.html
Option C is valid as written and removes all selectors.
Option B is clearly intended to represent the empty-string approach, but the uploaded document contains malformed syntax. It requires correction before it can be executed.
Option A removes the foo selector but leaves woo , producing path/page.woo.html .
Option D uses a comma-separated string rather than the documented selector string format, which uses periods, or an array of selector values. It therefore cannot be relied upon to remove the individual selectors.
Verification finding: B and C are the intended examination answers. Strictly evaluated without correcting the original source, only C is demonstrably valid. This question requires a source correction before inclusion in a technically accurate practice test.

NEW QUESTION # 25
A developer has enabled log-file rotation.
Why is this process important for managing log files?
Choose three
Answer: A,B,C
Explanation:
Comprehensive Explanation
Log-file rotation is an operational mechanism used in Adobe Experience Manager to prevent continuously growing log files from consuming excessive filesystem capacity.
AEM uses the Apache Sling logging infrastructure, which supports configurable rotation policies based on maximum file size or elapsed time.
Option B represents a principal benefit of size-based rotation. When the active log file reaches its configured threshold, the logging system rotates it and creates a new active log file.
Option C describes the storage-management benefit when rotation is combined with a suitable retention policy. By limiting the number of historical log files retained, administrators can prevent uncontrolled accumulation of diagnostic data.
Option A requires qualification. Rotation does not necessarily delete all previous log files. Instead, older files may be retained as rotated versions, with files beyond the configured retention limit subsequently removed.
Adobe documents configurable settings for the number of log-file versions retained, rotation intervals, and maximum file sizes.
These controls are especially important when DEBUG-level logging is enabled, because verbose diagnostic output can rapidly consume storage.
For production environments, rotation thresholds and retention limits should be selected according to storage capacity, troubleshooting requirements, and applicable log-retention policies.
Verification finding: All three selections match the intended question, but option A is imprecise. Log deletion depends on retention settings, and size limitation depends on the configured rotation strategy.

NEW QUESTION # 26
A customer has a topology where the cache flush agent is not configured.
Which two methods would the developer use to update the cache?
Choose two
Answer: A,B
Explanation:
Comprehensive Explanation
Adobe Experience Manager Dispatcher documentation identifies two principal mechanisms for updating cached content: Content Updates and Auto-Invalidation.
Content Updates remove specific cached documents and related resources when content changes. This enables Dispatcher to retrieve fresh representations from the rendering instance when subsequent requests arrive.
Auto-Invalidation uses timestamp-based validation through statfiles. When an appropriate invalidation event occurs, Dispatcher updates the relevant statfile. Cached documents subject to automatic invalidation are subsequently checked against the statfile timestamp to determine whether they are stale.
Option A therefore identifies one documented cache-update mechanism, while option D identifies the other.
Options B and C are incorrect because restarting an AEM Author or Publish instance does not inherently remove or invalidate files held in the Dispatcher web server's cache directory.
Operational qualification: The absence of a Dispatcher Flush Agent matters. Content Updates and Auto- Invalidation are mechanisms, not independent triggers that necessarily detect AEM publications without configuration. In a traditional topology, the Dispatcher must still receive a suitable invalidation request or use another correctly configured mechanism, such as time-based expiration.
Therefore, A and D match Adobe's documented cache-update methods, but the question should not imply that both automatically respond to content changes when no cache-invalidation mechanism is configured.

NEW QUESTION # 27
Under AEM Sites Capabilities in AEM as a Cloud Service, which feature is recommended as the replacement when the JavaScript Use API has been deprecated?
Answer: B
Explanation:
Comprehensive Explanation
Adobe has deprecated the JavaScript Use API for AEM as a Cloud Service and explicitly identifies the Java Use API as its recommended replacement.
The JavaScript Use API historically allowed developers to implement server-side component logic using JavaScript files referenced through HTL's data-sly-use mechanism.
The Java Use API provides an alternative architecture that separates presentation markup from application logic through Java classes and Sling Models.
Java-based implementations can provide stronger compile-time type checking, dependency injection, reusable service integrations, and more structured unit-testing capabilities.
The HTL layer remains responsible for rendering presentation markup, while Java classes handle data processing and application-specific functionality.
Option A, the JCR API, provides repository access and content-manipulation capabilities. It does not replace the component-level HTL Use API.
Option C, the Jackrabbit Oak API, relates to the underlying content repository implementation and is not the recommended replacement.
Option D, the Assets HTTP API, provides asset-related operations and is unrelated to the JavaScript Use API's primary purpose.
Adobe's AEM as a Cloud Service documentation explicitly lists JavaScript Use API under deprecated Sites functionality and identifies Java Use API as its replacement.
For new development, developers should implement business logic using Java-backed components and appropriate Sling Models rather than creating new dependencies on deprecated server-side JavaScript implementations.
Official Adobe Reference: Deprecated and Removed Features - Sites, JavaScript Use API; Getting Started with HTL - Java Use API.
NEW QUESTION # 28
A developer needs to use AEM Core Components in production mode, without sample content. The developer wants to do so without having to download and install the Core Components before using them.
Which AEM product should the developer use?
Answer: C
Explanation:
Comprehensive Explanation
Adobe Experience Manager as a Cloud Service includes AEM Core Components as part of the managed platform, eliminating the requirement for developers to install the Core Components package manually.
Core Components provide standardized, extensible implementations of common website functionality, including text, images, titles, navigation, containers, and other presentation components.
Adobe maintains the Core Components within AEM as a Cloud Service and provides compatible component versions as part of platform updates.
In contrast, traditional AEM 6.5 deployments and Adobe Managed Services environments may require Core Components to be included as application dependencies or installed as part of the deployment process.
Option B is therefore not the most appropriate choice because Adobe Managed Services environments do not provide the same automatic Core Components availability model as AEM as a Cloud Service.
Option C is incorrect because AEM 6.3 predates the modern Core Components architecture supported by current AEM implementations.
The requirement to avoid sample content is also compatible with AEM as a Cloud Service. Developers can configure their AEM project without deploying optional demonstration content.
One important distinction remains: although Core Components are installed automatically, project developers must still configure their availability through appropriate proxy components, editable templates, and content policies.
