Question No. 1

A developer wants to replace the element name of the host element with titleLevel property of the model in HTL.

Which action would be taken to complete this task?


Show Answer Hide Answer
Correct Answer: C

In HTL (HTML Template Language), data-sly-element is used to dynamically set the name of a DOM element. The provided option C correctly demonstrates the use of data-sly-element to replace the element name with the value of the titleLevel property of the model. The context 'unsafe' is specified because changing the element name can be a security risk if the value is not properly sanitized since it could lead to script injection vulnerabilities if used with user-provided data.

Options A and B are incorrect because they don't use the data-sly-element attribute, which is necessary to dynamically change the tag name of the element in HTL.


Question No. 2

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?

Show Answer Hide Answer
Correct Answer: C

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 named start.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.


Question No. 3

An author wants to define a blueprint configuration to identify an existing website that will be used as the source for one or more live copy pages.

Which two structure rules must the content author follow? (Choose two.)

Show Answer Hide Answer
Correct Answer: B, D

When defining a blueprint configuration in AEM, the content author must adhere to certain structure rules to ensure the proper functioning of the live copy mechanism. The rules include:

B) The immediate child pages of the root are language branches of the website - This structure is commonly used in AEM to organize content according to language and regional variations, allowing for more manageable and scalable content management across different locales.

D) The website should have a single page as the root - Having a single root page for a website is a standard practice in AEM as it simplifies the content hierarchy and provides a clear entry point for the site structure. This root page then serves as the source for live copies.

Options A and C are not strict requirements for a blueprint configuration. AEM does not mandate that the root of each language branch has at least two child pages or that each language page must have a country child page. These decisions are usually based on the specific content structure and organizational needs of the website.


Question No. 4

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?

Show Answer Hide Answer
Correct Answer: A

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, the text selector 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. The plain selector might suggest a text/plain MIME type, but in AEM, the correct selector for retrieving the text content of an Experience Fragment is text.


Question No. 5

A developer has modified an existing workflow model in AEM, which defines series of steps to be executed. When a user starts this workflow, recent changes/workflow steps are not available in the workflow instance.

What could be the reason for this behavior of the Workflow Model?

Show Answer Hide Answer
Correct Answer: A

When modifications are made to a workflow model in AEM, they must be saved and synchronized with the running instance of AEM. If a user starts a workflow and does not see the recent changes or workflow steps, it could be because the workflow model was not synced in runtime. This means the running instance of AEM is not yet aware of the changes, and as a result, the workflow instance uses the old version of the workflow model.

Option B is incorrect because permissions would not cause the recent changes to be unavailable; they would more likely prevent the user from starting the workflow at all.

Option C is also incorrect because while errors in subsequent steps could potentially stop the workflow from proceeding, they would not prevent new steps from appearing in the workflow instance if they were properly saved and synced.
