NEW QUESTION # 16
Which property under /cache on dispatcher.any file identifies the directory where cached files are stored?

• A. /cacheroot
• B. /docroot
• C. /invalidate
• D. /statfile

Answer: A

Explanation:
The /cacheroot property under /cache in the dispatcher.any file identifies the directory where cached files are stored. It is a relative or absolute path to the cache root directory. The dispatcher creates a subdirectory for each virtual host under this directory and stores thecached files there.

NEW QUESTION # 17
A snippet throws an exception at runtime:
@Model(adaptables = {Resource.class}) public class MyCustomModel {
(SSIingObject
private Resource resource;

What should the developer add to fix it?

• A. throws Exception at the end of the init method declaration
• B. (Optional annotation to page field
• C. defaultlnjectionStrategy = DefaultlnjectionStrategy property to @Model Class annotation
• D. SlingHttpServletRequest.class to adaptables property of Model Class annotation

Answer: C

Explanation:
Explanation
The developer should add the defaultInjectionStrategy = DefaultInjectionStrategy property to the @Model Class annotation to fix the snippet. The defaultInjectionStrategy property defines how the Sling Model handles missing or null values for the injected fields. By default, the Sling Model uses the REQUIRED injection strategy, which means that all fields must have a non-null value or else an exception is thrown. By setting the defaultInjectionStrategy property to OPTIONAL, the Sling Model allows null values for the injected fields and does not throw an exception. This way, if the page field is null because the resource is not a page, the Sling Model can still work without errors. References:

NEW QUESTION # 18
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. Read the key value from a property file stored in the code base
• B. Use an environment variable which is then consumed by an OSGi configuration
• C. Use a context aware configuration
• D. Read the key value from OSGi configuration stored in run nNdes

Answer: B

Explanation:
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. References:

NEW QUESTION # 19
Which OSGi configuration values can be used in an AEM as a Cloud Service Implementation?

• A. Inline, secret environment-specific
• B. Inline.restricted,runmode-specific
• C. Inline, secret, runmode-specific
• D. Inline, restricted. environment-specific

Answer: A

Explanation:
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"
}

• A. $[secret:ENV_VAR_NAME]
• B. $[env:SECRET_VAR_NAME]
• C. $[env:ENV_VAR_NAME]
• D. $[secret:SECRET_VAR_NAME]

Answer: D

Explanation:
Explanation
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. References:

NEW QUESTION # 22
Which AEM as a Cloud Service role can configure or run pipelines?

• A. Developer
• B. DevOps
• C. Program Manager
• D. Deployment Manager

Answer: D

Explanation:
The Deployment Manager is a role that can configure or run pipelines in Cloud Manager. The Deployment Manager can create and edit programs and environments, configure pipelines, start and cancel pipeline executions, and approve or reject deployments to production. The Deployment Manager role requires an IMS ID that is associated with the Adobe ExperienceCloud product profile. References:

NEW QUESTION # 23
Which query parameter needs to be added and set to true to debug a CQ HTML client library in the AEM author instance?

• A. debugClienlLib
• B. debugClientLibs
• C. debuggerClienlLib
• D. debuggerClientLibs

Answer: B

Explanation:
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.
References:
* Debugging Client Libraries in AEM

NEW QUESTION # 24
In a non-optimized website, the final HTML generated for a typical page by publish instance includes a relatively large number of <script> elements that refer to other script files loaded from AEM environment. The developer wants to minimize these network calls by combining all required client library code into a single file to reduce the number of back-and-forth requests on page load.
Which step should a developer take to solve this issue?

• A. Embed the required libraries into an app-specific client library using the dependencies property of the cq:Clientl_ibraryFolder node
• B. Add the categories property of the cq:Clientl_ibraryFolder node into an app-specific client library folder
• C. Embed the required libraries into an app-specific client library using the allowProxy property of the cq:Clientl_ibraryFolder node
• D. Embed the required libraries into an app-specific client library using the embed property of the cq:ClientLibraryFolder node

Answer: A

Explanation:
The embed property of the cq:ClientLibraryFolder node allows embedding code from a client library into another client library. At runtime, the generated JS and CSS files of the embedding library include the code of the embedded library. This reduces the number of network calls and improves performance. Embedding code is useful for providing access to libraries that are stored in secured areas of the repository. References:

NEW QUESTION # 25
If multiple configurations for the same PID are applicable, which configuration is applied?

• A. The one that occurs first in the repository is applied.
• B. The last modified configuration is applied.
• C. A configuration factory is created and all configurations are applied.
• D. The configuration with the highest number of matching run modes is applied.

Answer: D

Explanation:
Explanation
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.

NEW QUESTION # 26
Which attribute must be present in all filter rules in AEM dispatcher configuration?

• A. /url
• B. /selectors
• C. /type
• D. /glob

Answer: D

Explanation:
The /glob attribute is mandatory for all filter rules in the dispatcher configuration. It specifies a pattern that is matched against the incoming request URL. If the pattern matches, the rule is applied. The /glob attribute can use wildcards (*) and placeholders ($1, $2, etc.) to match parts of the URL.

NEW QUESTION # 27
What is the correct order of resolution of OSGi configuration at Runtime?

• A. 1. Modifying a configuration in the Web console will take immediate effect as it takes precedence at runtime.
  2. Modifying a configuration in /apps will take immediate effect
  3. Modifying a configuration in /libs will take immediate effect, unless it is masked by a configuration in
  /apps.
• B. 1. Modifying a configuration in /apps will take immediate effect
  2. Modifying a configuration in the Web console will take immediate effect as it takes precedence at runtime.
  3. Modifying a configuration in /libs will take immediate effect, unless it is masked by a configuration in
  /apps.
• C. 1. Modifying a configuration in /libs will lake immediate effect, unless it is masked by a configuration in
  /apps O 2. Modifying a configuration in /apps will take immediate effect
  3. Modifying a configuration in the Web console will take immediate effect as it takes precedence at runtime.
• D. 1. Modifying a configuration in the Web console will take immediate effect as it takes precedence at runtime.
  2. Modifying a configuration in /libs will take immediate effect, unless it is masked by a configuration in
  /apps.
  3. Modifying a configuration in /apps will lake immediate effect.

Answer: A

Explanation:
The order of resolution for OSGi configurations at runtime in AEM is as follows:
* Web Console Configuration:
* Changes made through the OSGi Web Console take immediate effect and have the highest precedence. This is because these configurations are considered the most direct way to adjust OSGi settings at runtime.
* References:OSGi Configuration in AEM
* /apps Configuration:
* Configurations in the /apps directory take precedence over those in the /libs directory. This allows custom configurations to override the default configurations provided by AEM.
* References:AEM Project Structure
* /libs Configuration:
* Configurations in the /libs directory are the default configurations provided by AEM. They are overridden by any configurations in the /apps directory.
* References:AEM Configuration
By understanding this order, developers can effectively manage and prioritize their OSGi configurations to ensure the desired behavior of their AEM instances.

NEW QUESTION # 28
How should a developer create a custom log configuration?

• A.
• B.
• C.

Answer: C

Explanation:
To create a custom log configuration in AEM, the developer should create an OSGi configuration file for the org.apache.sling.commons.log.LogManager.factory.writer component. This configuration file should be placed under the appropriate runmode-specific folder within the config directory.
Here is the detailed process:
* Create Configuration File:
* Create a new XML file named
org.apache.sling.commons.log.LogManager.factory.writer-<identifier>.xml in the config.<runmode> folder.
* The <identifier> can be any unique identifier for your custom log configuration.
* Specify Configuration:
* Add the necessary configuration properties within this XML file. For example:
<?xml version="1.0" encoding="UTF-8"?>
<jcr:root
xmlns:sling="http://sling.apache.org/jcr/sling/1.0"
xmlns:jcr="http://www.jcp.org/jcr/1.0"
jcr:primaryType="sling:OsgiConfig"
org.apache.sling.commons.log.file="/var/log/custom.log"
org.apache.sling.commons.log.level="debug"
org.apache.sling.commons.log.pattern="\{0\}"
org.apache.sling.commons.log.names="[com.myproject.custom]" />
* Deploy Configuration:
* Save the configuration file and deploy it to the appropriate environment. The logging system in AEM will pick up this configuration and create a custom log file with the specified settings.

* Apache Sling Logging

NEW QUESTION # 29
Which practice should be used to push a code fix to make it into the current release candidate?

• A. Cherry-pick the fix commit into the release candidate.
• B. Make the fix locally and upload the package to where the release candidate is deployed.
• C. Create a new release candidate from the master branch.
• D. Make the fix in CRX where the current release candidate is currently deployed.

Answer: A

Explanation:
To push a code fix into the current release candidate, the best practice is to cherry-pick the fix commit into the release candidate branch. Cherry-picking allows you to apply specific changes from one branch to another, ensuring that only the necessary fixes are included without introducing unrelated changes.
Here's how to cherry-pick a commit:
* Identify the Commit: Locate the commit hash of the fix you need to apply. This can be found in your
* version control system (e.g., Git).
* Checkout the Release Candidate Branch:
git checkout release-candidate-branch
Cherry-pick the Commit:
git cherry-pick <commit-hash>
Resolve Conflicts(if any): If there are conflicts, resolve them manually and then continue the cherry-pick process:
git add <resolved-files>
git cherry-pick --continue
Test the Changes: Ensure that the changes are tested thoroughly in the release candidate environment to confirm the fix works as expected.
Push the Changes:
git push origin release-candidate-branch
Cherry-picking ensures that only the required changes are applied to the release candidate, maintaining the stability and integrity of the codebase.
