• Question 12:

  An AEM Developer needs to create a new component to help support a new product launch.

  The client is on AEM 6.5 on-premise with the latest version of WCM Core Components The component must include text, image, and a link The component must support multiple designs

  Which process should the AEM Developer use to support the launch?

  A. 1. Extend the Teaser Component from Core Components

  2. Create style variations to be used in the Style System

  B. 1. Create a new component by extending the Text Component from Core Components

  2. Add dialog properties and modify HTL to support images

  C. 1. Extend the Text Component from Core Components

  2. Enable image manipulations for the Text Component via policy

  D. 1. Create a new Image with Text component that exposes the Core Components authoring dialogs for those components

  2. Add a policy to define which designs are used

  Correct Answer: A

  Extend the Teaser Component from Core Components Create style variations to be used in the Style System** Comprehensive of Correct Answer Only: The Teaser Component from Core Components is a component that allows authors to display a title, description, image and link for a teaser item. The component supports multiple designs and can be extended to add custom features or logic. The Style System allows authors to define style variations for components without requiring code changes or new templates.

• Question 13:

  What is the recommended path to override /libs standard functionality?

  A. /conf

  B. /apps

  C. /content

  D. /Iibs

  Correct Answer: B

  The recommended path to override /libs standard functionality is /apps. The /apps folder contains application-specific code and configuration that can extend or override the default functionality provided by /libs. The /apps folder has

  precedence over the /libs folder, meaning that if there are two resources with the same path under both folders, the one under /apps will be used.

• Question 14:

  A developer needs to create sling models for two fields name and occupations. The dialog has two fields, name - a single value field, and occupations - a multi value field. The following code is included in sling models inherited from interface com.adobe.aem.guides.wknd.core.models.Byline

  

  A. Option A

  B. Option B

  C. Option C

  D. Option D

  Correct Answer: C

  Explanation: Option C is the correct implementation for the Sling Model. Option C uses the @Model annotation with the adaptables parameter set to Resource.class. This allows the Sling Model to adapt from a resource object and access its properties using the ValueMap interface. Option C also uses the @Inject annotation with the name parameter set to "./name" and "./occupations" to inject the values of the name and occupations properties into the name and occupations fields. Option C also uses the @Named annotation with the value parameter set to "byline" to specify the name of the Sling Model that can be used in HTL scripts.

• Question 15:

  A developer has to create a Logger and Writer pair for the company's application logging. Which OSGi configurations should the developer use?

  A. Apache Sling Logging Logger Configuration and Apache Sling Logging Configuration

  B. Apache Sling Request Logger and Apache Sling Logging Writer Configuration

  C. Apache Sling Logging Logger Configuration and Apache Sling Logging Writer Configuration

  Correct Answer: C

  Explanation: The Apache Sling Logging Logger Configuration and Apache Sling Logging Writer Configuration are the OSGi configurations that the developer should use to create a Logger and Writer pair for the company's application logging. The Logger Configuration defines the log level and the log file name for a given logger name or category. The Writer Configuration defines the file size, number of files, and file location for a given log file name.

• Question 16:

  An AEM development team is working on a new multi-country application using AEM as a Cloud Service. A developer has been assigned the task for building the integration with a third-party web service. A secret key is needed to connect

  with this web service. The website creators will provide this key. The key is different for each type of environment (dev, stage and production)

  What is the recommended way to make the secret key available in the AEM application?

  A. Use a context aware configuration

  B. Read the key value from a property file stored in the code base

  C. Use an environment variable which is then consumed by an OSGi configuration

  D. Read the key value from OSGi configuration stored in run nNdes

  Correct Answer: C

  Explanation: The recommended way to make the secret key available in the AEM application is to use an environment variable which is then consumed by an OSGi configuration. This way, the secret key is not stored in the code base or in the repository, but rather in a secure and encrypted way in the Cloud Manager environment variables. The OSGi configuration can use a placeholder to reference the environment variable and inject its value at runtime.

• Question 17:

  An application development team needs to create a multi-channel application that uses AEM as a headless CMS. Which feature should be used to maintain structured data for this application?

  A. Static template

  B. Content fragment

  C. Experience fragment

  D. Custom component

  Correct Answer: B

  Explanation: A content fragment is a reusable piece of content that can be authored and managed independently from a page. Content fragments are based on structured data models that define the elements and data types of the content.

  Content fragments can be delivered as JSON using various APIs, such as Assets HTTP API, Content Fragments REST API, or Content Fragments GraphQL API. Content fragments are suitable for creating multi-channel applications that use

  AEM as a headless CMS. References:

  lang=en

• Question 18:

  An AEM application is expected to export a content fragment in JSON format without any customization for a headless implementation.

  What is the recommended approach?

  A. Use AEM Assets HTTP API

  B. Use Core components to export JSON

  C. Use Sling Exporter framework

  Correct Answer: A

  Explanation: AEM Assets HTTP API is a RESTful API that allows access to content fragments in JSON format without any customization. The API supports CRUD operations on content fragments and their variations, as well as querying and searching for content fragments based on metadata or full-text search.

• Question 19:

  Which configuration must be applied to enable re-fetching of cached items based on Cache Headers sent by AEM?

  A. /autolnvalidate true

  B. /autolnvalidate "1"

  C. /enableTTLtrue

  D. /enableTTL "1"

  Correct Answer: D

  Explanation: The /enableTTL "1" configuration must be applied to enable re-fetching of cached items based on Cache Headers sent by AEM. This configuration enables the Time To Live (TTL) feature of dispatcher, which allows dispatcher to check the Cache-Control and Expires headers of the cached files and re-fetch them from AEM if they are expired.

• Question 20:

  What two types of testing are available OOB in AEM Cloud Manager Pipeline? (Select Two.)

  A. Code Quality testing

  B. Performance testing

  C. Ul testing

  D. Penetration testing

  E. Integration testing

  Correct Answer: AC

  Explanation: Code Quality testing and UI testing are two types of testing that are available OOB in AEM Cloud Manager Pipeline. Code Quality testing checks the code quality of the project using SonarQubeand reports any issues or

  vulnerabilities. UI testing checks the functionality and usability of the project using Selenium WebDriver and reports any errors or failures.
