AD0-E123 Adobe Experience Manager Sites Developer Professional Question and Answers

In Adobe Experience Manager, the correct resource type for an OSGi configuration node issling:OsgiConfig. This resource type is used to define nodes in the repository that represent OSGi configurations. These configurations can then be read by OSGi components within AEM to configure their behavior according to the defined properties.

• Option A,cq:Configuration, is not used for OSGi configuration nodes. It might be used within the context of Context-Aware Configuration but not for defining OSGi configurations.
• Option C,cq:OsgiConfig, is not a valid resource type for OSGi configurations in AEM. The correct namespace for OSGi configurations in AEM issling, hencesling:OsgiConfig.

A Java service, which is a backend Java class that encapsulates some business logic or functionality, should be placed in thecoreMaven module of an AEM project. This module is intended for the Java code that contains OSGi services, servlets, and other Java backend code. By creating the service in thecoremodule, it can be properly compiled, packaged, and deployed as an OSGi bundle within AEM.

In AEM, the Sightly/HTL scripting language is used to develop robust and secure components. To render content conditionally based on the WCM (Web Content Management) mode, thewcmmodeobject is used. The correct property to check if the current mode is edit iswcmmode.edit. The HTL syntax for testing a condition isdata-sly-testfollowed by the condition in${}. The option B correctly uses this syntax to test if the WCM mode is edit, and if so, renders "Hello World".

• Option A useswcm.editwhich is not the correct object property.
• Option C useswcmmode editorwhich is not the correct property and the syntax has a typo (should bedata-sly-test).

When an AEM instance starts with specified run modes, it selects configurations from the repository that match those run modes. Run modes allow for flexible management of settings and configurations across different environments. For the instance started with 'author', 'dev', and 'emea' run modes, it would apply configurations from paths that match these run modes.

Option B,/config/author.dev.emea.noldap, is correct. This path matches all three run modes specified and would, therefore, be included.

Option D,/apps/mysite/config.author.emea.dev, is also correct. This path matches the run modes and would be applied to the instance as well.

Options A and C do not match all three run modes and therefore would not be applied.

In Adobe Experience Manager (AEM), a transient workflow is designed for short-lived workflows that do not persist their state information in the repository, which means they are faster and do not leave a footprint in the repository. However, if a Process Step in a transient workflow creates a sling job, it defeats the purpose of the transient workflow because sling jobs are persisted in the repository and could generate error messages in the log files if they are not executed immediately or if there are issues with the job queue. Therefore, to maintain the transient nature of the workflow, Process Steps that create sling jobs should be avoided.

• The Container Step (Option A) is used to group other workflow steps and does not inherently create sling jobs.
• The Goto Step (Option B) is used for branching logic and also does not create sling jobs.

In the context of AEM as a Cloud Service, a "Golden Master" typically refers to the production-ready, main branch within the Cloud Manager Git Repository. This repository is used to manage and deploy code to AEM Cloud Service environments. It is considered the source of truth for the codebase that is used to build, test, and deploy AEM applications in the cloud.

Given the dispatcher configuration snippet provided in the image, we can understand the URL patterns that will be ignored (not cached) by the dispatcher. The configuration under/ignoreUrlParamsshows patterns to match query parameters in the URLs:

• /0001 { /glob "*" /type "deny" } means that by default, all query parameters are ignored (not cached).
• /0002 { /glob "search" /type "allow" } specifically allows caching for URLs with the 'search' parameter.
• /0003 { /glob "order" /type "allow" } specifically allows caching for URLs with the 'order' parameter.

Based on this, let's evaluate the options:

A. /myproduct/myrecipe.html?search=searchparam — This URL will not be cached because the 'search' parameter is allowed, but the actual value 'searchparam' does not match any allow pattern. B. /myproduct/myrecipe.html?search=s&order=asc&brand=ad — This URL will not be cached because although 'search' and 'order' parameters are allowed, the 'brand' parameter is not allowed according to the configuration. C./myproduct/myrecipe.html?brand=mybrand — This URL will be cached because there are no allowed parameters, so the default deny does not apply, and the page can be cached without considering the 'brand' parameter.

Therefore, the page that will be cached on the dispatcher is the one in option C, as it does not contain any of the explicitly allowed query parameters ('search' or 'order'), and all other parameters are ignored by default.

To enable the SAML (Security Assertion Markup Language) Authentication Handler in Adobe Experience Manager (AEM), certain critical properties need to be configured to establish the necessary trust and communication between the Identity Provider (IdP) and the Service Provider (SP, which in this case is AEM).

A.IDPURL(Identity Provider URL) - This property is essential for configuring the SAML Authentication Handler as it specifies the URL of the Identity Provider. This URL is used by AEM to redirect authentication requests to the IdP. It is crucial for initiating the SAML SSO (Single Sign-On) process.

D.Service Provider Entity ID- This is a unique identifier for the Service Provider (AEM in this context). It is used by the Identity Provider to recognize the Service Provider. The Entity ID is a key component of the SAML assertions and is used to ensure that the SAML responses are directed to the correct entity.

B.Password of Key Storeis important for securing the communication between IdP and SP by encrypting the SAML assertions, but it is not mandatory for the basic enablement of the SAML Authentication Handler.

C.Identity Provider POST URLis used in scenarios where the SAML response from the IdP is sent via HTTP POST. While it's important for the SAML configuration, the initial enablement and basic functionality of the SAML Authentication Handler primarily depend on the IdP URL and the SP Entity ID.

In HTL, theformatoption in the data-sly-use or data-sly-test attribute can be used to format values according to a pattern. The pattern'-#.##%'indicates that the number should be formatted as a percentage with up to two decimal places. ThepiValuevariable would be the number to format, and in this example, it would convert -3.14 to -314%. The@symbol is used to denote the use of an option with the variable in HTL.

• Options B and C are incorrect because they do not use the correct syntax for the format option in HTL. The use of@is to specify options and not part of the variable or pattern itself.

AEM as a Cloud Service includes the latest AEM features out-of-the-box, including AEM Core Components, which are production-ready without the need for additional downloads or installations of sample content. This version of AEM has a continuousdelivery model, ensuring that the most up-to-date features and components are readily available.

• Option A, Version 6.3, is incorrect because this version would require the manual download and installation of core components.
• Option B, Adobe Managed Services, is not a version of AEM, but rather a hosting option that could include various versions of AEM.

In HTL (HTML Template Language), the syntax to manipulate the URI path does not provide direct methods for removing selectors. However, within Sling and HTL, the Link Handler can be extended to support such operations. For out-of-the-box HTL, the proper approach to manipulate the link would be done in the Java layer (e.g., a Sling Model or a Use-Class in HTL), and then passed to the template for rendering. Nevertheless, if such a functionality were to be implemented within HTL, it would require custom code and not use the indicated syntax options. It is important to note that options A and B with 'removeSelectors' are not standard HTL syntax.

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.
