A developer creates two custom classes. ClassA has the following code:
package com.aem.abc;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class ClassA {
private static final Logger logger = LoggerFactory.getLogger(this.getClass()); public void classAMethod() { logger.debug("Message from Class A method");
}
}
The developer creates a custom log custom.log with debug level in OSGi sling log support for the Java package com.aem.abc. The developer adds another class ClassB with the following code:
package com.aem.xyz;
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
public class ClassB {
private static final Logger logger = LoggerFactory.getLogger(this.getClass()); public void classBMethod() { logger.debug("Message from Class B method");
}
}
Which action must the developer take to see the log messages in the same file from both classes?

• A. Configure custom.log in OSGi web console -> Sling -> Log Support and replace com.aem.abc with com.aem
• B. Configure custom.log in OSGi web console -> Sling -> Log Support and replace com.aem.xyz with com.aem.abc
• C. Configure custom.log in OSGi web console -> Sling -> Log Support and replace com.aem.abc with com.aem.xyz
• D. Create separate a log file in the OSGi web console -> Sling -> Log Support for logger com.aem.xyz

A developer is working on a complex project with multiple bundles. One bundle provides an OSGi service for other bundles.
Which two options are necessary to ensure that the other bundles can reference that OSGi service? (Choose two.)

• A. The bundles consuming the service need to import the fully qualified name of the service interface.
• B. The service needs to correctly declare metatype information.
• C. The bundle providing the service needs to contain a whitelist of allowed consumer bundles.
• D. The bundle providing the service needs to contain an adequate SCR descriptor file.
• E. The bundle providing the service needs to export the java package of the service interface.

A developer wants to extend AEM Core Components to create a custom Carousel Component.
How should the developer extend the Core Components?

• A. Use the sling:resourceType property to point to the core component.
• B. Copy the Core Carousel component to /apps/<project> folder.
• C. Make changes to the original component and assign a component group.
• D. Use the sling:resourceSuperType property to point to the core component.

A developer creates a custom Client Library named foobar.
This Client Library embeds 5 other Client Libraries and contains 10 JavaScript source files. One of these files, called foo.js, has a bug on line 8 which causes an exception. The Client Library is throwing this exception on line 1350 when it is included on a webpage.
How should a developer find the exact line in foo.js where the exception has been thrown?

• A. 1. Enable JS/CSS minification in OSGi configuration console for HTML Library Manager.2. Check the JavaScript exception log in the OSGi web console.
• B. 1. Temporarily remove the embedded Client Libraries of the foobar Client Library.2. Use the browser JavaScript debugging tools.
• C. 1. Add the query parameter debugClientLibs=true to the request.2. Use the browser JavaScript debugging tools.
• D. 1. Add the selector debugClientLibs to the page request.2. Check the JavaScript exception log in the OSGi web console.
