How should the developer extend the Core Components?

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



Question 3
A developer wants to change the log level for a custom API. 
Which OSGi configuration should the developer modify?

  • A: Apache Sling Logging Configuration
  • B: Apache Sling Log Tracker Service
  • C: Apache Sling Logging Writer Configuration
  • D: Adobe Granite Log Analysis Service



Question 4

A developer uses the following:

  

What is the resulting HTML?

  • A:
      
  • B:
      
  • C:
      
  • D:
      



Question 5
A developer needs to implement a service component that should be manually configured 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?

  • 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.
  • 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.
  • 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.
  • 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.



Question 6
A developer creates a custom component. The component dialog includes the following two fields:

  

The component should display the first ‘X’ characters of the text entered in the ‘text’ input where ‘X’ is the number entered in the ‘charLimit’ input. If zero, or no value, is entered in the ‘charLimit’ input then the text should be unaltered. The developer creates the following Sling Model to perform the trancation:

  

A Null Pointer Exception occurs if NO charLimit values is set in the component dialog. 
What should the developer do to resolve this issue?

  • A: Replace the defaultValue=”0” attribute of the ‘charLimit’ field in the dialog with min=”0”.
  • B: Add the @Default annotation to the ‘chatLimit’ variable in the Sling Model.
  • C: Replace the defaultValue=”0” attribute of the charLimit field in the dialog with defaultValue=”0”.
  • D: Change the defaultInjectionStrategy of the Truncation Sling Model to DefaultInjectionStrategy.REQUIRED.



Question 7
A custom AEM application contains Bundle A and Bundle B. Bundle A has a dependency to Bundle B via Import-Package. 
How can both bundles be deployed most efficiently across all environments?

  • A: Use the Felix Web Console to upload the bundles in the correct order.
  • B: Create one content package per bundle and use a package dependency to ensure installation order.
  • C: Embed both bundles in one content package and use property ‘installationOrder’ in package properties for correct bundle installation order.
  • D: Embed both bundles in one content package: the dependency via Import-Package is enough to ensure correct installation.



Question 8
After adding new features, a developer’s environment is experiencing slowness before ultimately running out of memory. The initial log analysis points towards a large number of open sessions. 
Which action should the developer take to further monitor the overall session count on this AEM instance?

  • A: Run the following command to generate thread dumps jstack -l <pid> >> threaddumps.log, analyze thread dumps to find long running sessions.
  • B: Go to Web Console > Status > Threads, verify the overall thread count.
  • C: Go to Tools > Operations > Monitoring. Create a new report based on Number of Active Sessions as metric.
  • D: Go to <aem-install>/crx-qiuckstart/logs/strderr/log, use the following command grep -o ‘CRXSessionImpl’ strderr.log| wc -l.



Question 9
An OSGi bundle Activator.java is registered through a service DevelopInfo.java 
DeveloperInfo.java 

  

Activator.java 

  

Maven install generates an error during deployment. Refer to the error information below:

  

Which action should the developer take to resolve the build error?

  • A: @Service annotation is missing in DeveloperInfo.java.
  • B: Interface DeveloperInfo does NOT have any method.
  • C: Activator class is NOT implementing DeveloperInfo interface.
  • D: The required Maven repository for OSGi is missing.



Question 10
A developer needs to analyze log messages for custom Java application. The developer writes the following Java class:

  

The developer creates a custom log named custom.log with a debug level in OSGi web console for Java package com.abc.xyz. 
Where should the developer look in the OSGi web console to view the above message?

  • A: OSGi -> Log Service and click logs/custom.log
  • B: Sling-> Log Support and click logs/custom.log
  • C: Sling -> Metrics and click logs/custom.log
  • D: AEM -> Log Support and click logs/custom.log
