Which Adobe-recommended best practice should the developer select?

QuestionQ4

Given a scenario, identify how to implement Sling Models and HTL

Refer to the exhibit.

Question Image

The current page contains three children. What is the final rendered HTML output of the code snippet?

Explanation

In Adobe HTL, data-sly-list repeats an annotated element’s content, leaving one surrounding <ul> with three <li> items. data-sly-repeat repeats the annotated element itself, so an annotated <ul> is rendered three times, each containing its original single <li>.

A developer must create a runmode-specific OSGi configuration for an AEM as a Cloud Service implementation.

Where should the OSGi configuration be created?

Explanation

Runmode-specific OSGi configurations for AEM as a Cloud Service are created in the ui.apps project beneath /apps/.../config.<runmode>. The configuration is typically a <PID>.cfg.json file in that folder.
