2. B. Use upload/install from OSGi console of publish instance

4. D. Use upload/install from OSGi console of author instance

Correct Answer: C

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 createsa 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;
importorg.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 mustthe developer take to see the log messages in the same file from both classes?

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

Correct Answer: D

Adeveloper created an editable template with a Layout Container. The developer needs to restrict the Layout Container to just one column layout.
What should the developer do to the editable template to enforce this restriction?

2. B. Overlay wcm.foundation.components.page.responsive Client Library and set @max_col to 1
3. C. Using Template Editor, lock the Structure Component for the template
4. D. Using Template Editor, set the responsive settings to 1 column for Layout Container Policy

Correct Answer: D

A developer needs to create a banner component. This component shows an image across the full width of the page. A title is shown on top of the image. This text can be aligned to the left, middle,or right. The core components feature a teaser component which matches almost all requirements, but not all.
What is the most maintainable way for the developer to implement these requirements?

1. A. Use and configure the teaser core component.
2. B. Create a new custom component from scratch.
3. C. Overlay the teaser core component.
4. D. Inherit from the teaser core component.

Correct Answer: D

A developer needs to implement a service component that should be manuallyconfigured by operations to react on operational circumstances. The service component should NOT be active by default. The service has the properties myservice.name (one string value) and myservice.stringValues (a list of the string values) to be configured.
The developer needs to use OSGi Metatype annotations to make those properties configurable in the Apache Felix Web Console.
Which set of steps should the developer take to meet these requirements?

1. A. 1. For the class fields myserviceName and myserviceStringValues, add a @AttributeDefinition annotation each with names set to myservice.name and myservice.stringValues respectively.2. Use the@Component annotation with configurationFactory = true on the service component class.3. Use the@Service service component class.4. Use the activate method of the service component class to get the configuration annotation interface class injected.
2. B. 1. Create an annotation interface as inner class of the service component and annotate it with@ObjectClassDefinition.2. Apply @AttributeDefinition for the methods myservice.name and myservice.stringValues.3. Use the @Component annotation with configurationPolicy = ConfigurationPolicy.REQUIRE on the service component.4. Use the @Designate annotation to link the service component to the created configuration annotation interface.5. Use the activate method of the service component class to get the configuration annotation interface class injected.
3. C. 1. Create an annotation interface as inner class of the service component and annotate it with@ObjectClassDefinition.2. Apply @AttributeDefinition for the methods myservice_name and myservice_stringValues.3. Use the @Component annotation with configurationPolicy = ConfigurationPolicy.REQUIRE on the service component.4. Use the @Designate annotation to link the service component to the created configuration annotation interface.5. Use the activate method of the service component class to get the configuration annotation interface class injected.
4. D. 1. For the class fields myserviceName and myserviceStringValues, add a @Property annotation each with names set to myservice.name and myservice.stringValues respectively.2. Use the @Component annotation with configurationFactory = true on the service component class.3. Use the @Service service component class.4. The configuration is automatically injected into the field by the service component runtime.
