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 accross all environments? Embed both bundles in one content package and use property 'installationOrder' in package properties for correct bundle installation order Create one content package per bundle and use a package dependency to ensure installation order Use the Felix Web Console to upload the bundles in the correct order Embed both bundles in one content package; the dependency via Import-Package is enough to ensure correct installation.
A developer needs guiadance to create mock for unit testing code.
Which of the following code snipper would result in a successful test? @Test

request = new SlingHttpServletRequest();
response = new SlingHttpServletResponse();
}
@Test

An AEM appication must process a high volumen of content ingestion on the author server.
What is a key factor to optimize a design for overall performance gain for implementing workflows? Use Transient workflows Allocate more RAM for the content ingestión up front. Run garbage collection every time content ingestión occurs. Use schedulers to run the workflows only on weeked.
A Null Pointer Exception occurs if NO charLimit values is set in the component dialog.
What should the developer do to resolve this issue? Replace the defaultValue="0" attribute of the "˜charLimit' field in the dialog with min="0". Add the @Default annotation to the "˜chatLimit' variable in the Sling Model. Replace the defaultValue="0" attribute of the charLimit field in the dialog with defaultValue="{Long}0". Change the defaultInjectionStrategy of the Truncation Sling Model to DefaultInjectionStrategy.REQUIRED.
An AEM Developer sets an argument variable “myVariable” to be consumed by workflow process in the same workflow model definition.
Which approach should be used? //Get myVariable directly from MetaDataMap
String myVariable = workItem.getMetaDataMap().get(“myVariable”); //Get myVariable from HistoryItem object
List<HistoryItem> history = workflowSession.getHistory(workItem.getWorkflow()); //Get myVariable from WorkflowData
String myVariable = workItem.getWorkflowData().getPayload().toString(); //Get myVariable from args
String args = metadataMap.get(“PROCESS_ARGS”,String.class);.

Make the changes in CRXDE create a content package, download it, and expand it into the working directory after each change. Install FileVault bundle in the AEM instance and register the local working directory for synchronization. Build a Content Package using maven and deploy it after each change.

The service user doesnt have appropiate WRITE permissions Assets API doesnt support UPDATE operation Asset API doesnt support WRITE operations for content fragment variations The developer needs must use PUT method instead of POST.
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 online 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? 1. Enable JS/CSS minification in OSGi configuration console for HTML Library Manager
2. Check the JavaScript exception log in the OSGi web console 1. Temporarily remove the embedded Client Libraries of the foobar Client Library.
2. Use the browser JavaScript debugging tools. 1. Add the selector debugClientLibs to the page request.
2. Check the JavaScript exception log in the OSGi web console 1. Add the query parameter debugClientLibs=true to the request.
2. Use the browser JavaScript debugging tools.

Which method would be a more modular approach to the solution? 1. Extrapolate out the states node to a more generic location.
2. Set that new location as the resourceSuperType 1. Extrapolate out the states node to a more generic location.
