Adobe Experience Manager Sites Developer AD0-E134 Exam Practice Test

Answer : A

To debug a CQ HTML client library in the AEM author instance, you need to add the query parameter debugClientLibs set to true. This parameter instructs AEM to include additional debugging information for client libraries, making it easier to troubleshoot issues with JavaScript, CSS, and other assets.

Steps to enable client library debugging:

Open the AEM Page: Navigate to the AEM page where you want to debug the client libraries.

Append the Query Parameter: Add ?debugClientLibs=true to the URL. For example:

http://localhost:4502/content/we-retail/us/en.html?debugClientLibs=true

Reload the Page: Refresh the browser page. AEM will now include debugging information for client libraries.

This parameter helps in identifying issues with client library loading, dependencies, and other client-side resources.

To ensure that text pasted inside the Text component in AEM is stripped of all styling and formatting, you need to override the RTE (Rich Text Editor) plugin implementation and change the default paste behavior. The correct option to achieve this is defaultPasteMode=plaintext.

Steps to configure the RTE plugin for plain text pasting:

Locate the RTE Configuration: Find the existing configuration for the RTE or create a new one in the /apps directory of your AEM project.

Modify the Plugin Configuration: Add or update the configuration to include the defaultPasteMode parameter. The configuration might look something like this:

{

'jcr:primaryType': 'nt:unstructured',

'features': '[text]',

'defaultPasteMode': 'plaintext'

}

Apply the Configuration: Ensure that this configuration is applied to the Text component. This typically involves updating the component dialog or design dialog to reference the updated RTE configuration.

Test the Configuration: In the AEM author instance, open the page with the Text component and paste text using CTRL+V. The pasted text should now be stripped of all styling and formatting, adhering to the plaintext mode.

By setting defaultPasteMode to plaintext, you ensure that the RTE only accepts plain text input, removing any formatting that might come from external sources.

Answer : C

This syntax allows the developer to reference a secret variable that is stored in the Cloud Manager UI under Environment Details > Variables. The secret variable name must start with a lowercase letter and can contain alphanumeric characters and underscores.

Answer : B

When multiple configurations for the same PID are applicable, the configuration with the highest number of matching runmodes is applied. This is because the runmodes act as a filter to select the most specific configuration for a given environment. If there is a tie between two or more configurations with the same number of matching runmodes, the one that occurs first in the repository is applied.

Answer : A

The JAAS Control flag SUFFICIENT is used when you have multiple LDAP authentication providers and you want the following behavior:

Immediate Return on Success:

If authentication succeeds with the current provider, control is returned to the caller immediately, and no subsequent providers in the list are executed.

This is efficient and reduces unnecessary processing if a user's credentials are successfully authenticated by one of the initial providers.

Continue on Failure:

If authentication fails with the current provider, the authentication process continues down the list of providers until a successful authentication occurs or all providers are exhausted.

This ensures that all available providers are tried before authentication is ultimately denied.

The SUFFICIENT control flag is thus well-suited for configurations where multiple authentication providers are used, and only one successful authentication is needed to grant access.

Sling Content Distribution is a feature that allows synchronizing user data across publish servers in a publish farm. Sling Content Distribution uses agents to distribute content from one instance to another using a publish-publish topology. Sling Content Distribution can be configured to synchronize user data under /home/users and /home/groups paths, as well as their ACLs.

In AEM as a Cloud Service, the OSGi configuration values that can be used include Inline, secret, and environment-specific. These configurations provide flexibility and security for managing environment-specific settings and sensitive information.

Inline Configurations: Inline configurations are directly embedded within the code and are typically used for straightforward configurations.

Secret Configurations: Secret configurations are used to securely store sensitive information, such as passwords and API keys. These configurations are managed separately to ensure security.

Environment-Specific Configurations: Environment-specific configurations allow you to tailor settings for different environments (e.g., development, staging, production) without changing the underlying codebase.

Example of using these configurations:

Inline Configuration:

{

'service.url': 'https://api.example.com'

}

Secret Configuration: Managed through Adobe IMS and not directly embedded in the code.

Environment-Specific Configuration:

{

'runmode': 'dev',

'service.timeout': '30'

}
