A developer is installing a content package with the package manager. The developer needs to restrict the approximate number of nodes in a batch that is saved to persistent storage in one transaction.
How should the developer modify the number of transient nodes to be triggered until automatic saving?

• A. Change the value of Save Threshold in the Install Package dialog-box.
• B. Modify the export package manifest header and copy the content package to AEM installation folder.
• C. Select the option MergePreserve for the Access Control Handling drop-down in the Install Package dialog-box.
• D. AEM instances automatically modify the number of transient nodes based on the load balancing.

A custom AEM application contains a service component that needs to access the JCR repository within the activate method. The activate method uses ResourceResolverFactory.getServiceResourceResolver(...) without specifying a sub service name.
What should a developer do to make sure the user service mapping for the service component is available?

• A. Create a field of type ServiceUserMapped and annotate it with @Reference using ReferencePolicy.DYNAMIC
• B. Create a field of type ServiceUserMapper and annotate it with @Reference using ReferencePolicy.STATIC
• C. Wait for the service ServiceUserMapper via BundleContext.getServiceReference(...)
• D. Create a field of type ServiceUserMapped and annotate it with @Reference

A developer is working on a dialog for a contact list component. The dialog has the following requirements:
1. The list of contacts must include one or more entries.
2. Contact details must include a full name.
3. Contact details must include an email address
4. Contact details can optionally include a short bio
5. Authors need to be able to rearrange the contacts in the list
Which dialog configuration should the developer use to meet all of these requirements?

• A. Option C
• B. Option D
• C. Option A
• D. Option B

The developer is presented with a component "Component A" which inherits from a component "Component B".
The dialog of Component A on path ../cq:dialog/../../items looks like:
+ align
- jcr:primaryType="nt:unstructured"
- sling:resourceType="granite/ui/components/coral/foundation/form/select"
- fieldLabel="Align Text"
- name="./align"
The dialog of Component B on path ../cq:dialog/../../items looks like:
+ title
- jcr:primaryType="nt:unstructured"
- sling:resourceType="granite/ui/components/coral/foundation/form/textarea"
- fieldLabel="Title"
- name="./title"
+ description
- jcr:primaryType="nt:unstructured"
- sling:resourceType="granite/ui/components/coral/foundation/form/textarea"
- fieldLabel="Description"
- name="./description"
The requirement for the dialog is that the *Align Text* field is shown after the *Title* field.
What should the developer do without changing Component B?

• A. Add the property sling:orderBefore="description" to the align node.
• B. Move the align node from Component A to Component B and order them according the requirements.
• C. Extend Component B with the functionality of Component A
• D. Move all the nodes under the item node from Component B to Component A and order them according the requirements.
