In AEM, fine-grained access control is managed using JCR Access Control Entries (ACEs). To grant access only to a specific node but exclude all child nodes, the correct approach is to set the rep:glob = "" property. This ensures that permissions apply strictly to the node itself and not recursively. Option B, rep:globs = "**", would apply access recursively to all descendants. Option C, rep:glob = "child", is invalid and does not represent a valid configuration. Adobe recommends precise use of rep:glob patterns to restrict user access according to security requirements, ensuring least-privilege principles.

To optimize queries against DAM assets with custom properties, developers must extend the existing damAssetLucene index. The correct method is to add the custom property under:

oak:index/damAssetLucene/indexRules/dam:Asset/properties. This ensures that the property is indexed for all assets and avoids traversal queries. Option B refers to a non-existent lucene index path, and Option C incorrectly suggests adding a property value (Hello) instead of the property name. Adobe’s indexing guidelines specify that extending existing Lucene indexes such as damAssetLucene is the standard approach for asset-related queries. This ensures queries remain efficient, scalable, and compatible across environments.

Explanation (Adobe Docs Reference):

The correct OSGi Declarative Services (DS) implementation in AEM:

Must use implements (not extends).

Must register the service interface (SimpleService.class).

Should return an implementation for getMessage().

Option D is the correct implementation.

Options A, B, C are wrong because:

A incorrectly uses extends.

B and C register the wrong service type (MySimpleService).

Adobe Documentation:

“An OSGi service implementation must implement its interface and be annotated with @Component(service=Interface.class) to register the service.”

Explanation (Adobe Docs Reference):

When querying with QueryBuilder API:

type=cq:Page ensures only AEM pages are selected.

property=jcr:content/cq:template filters by the template path.

property.value=/conf/geometrixx/templates/homepage ensures only pages created with the homepage template are returned.

p.hits=selective restricts returned properties.

p.properties=jcr:title ensures only the jcr:title is returned.

Options B, C, and D are invalid due to wrong property paths (jcr:title/cq:template, cq:template, or jcr:content/template) or typos (jrc:title).

Adobe Documentation:

“The property parameter can be used to restrict results based on template usage. Use jcr:content/cq:template to filter by template and p.properties with p.hits=selective to return specific fields.”
