Comprehensive Explanation

Adobe Experience Manager supports determining the initial instance run mode and listening port through the naming convention of its Quickstart JAR file.

For traditional AEM installations, the filename can include the instance type and port number.

The filename cq5-author-p4502.jar identifies an Author instance configured to start on port 4502.

The author component determines the instance role, while -p4502 identifies the configured HTTP port.

Option A is incorrect because it includes two port-related numeric values, making the naming structure unnecessarily ambiguous.

Option C does not follow Adobe's documented convention for specifying the instance type and port.

Option D also fails to follow the recommended convention and includes additional port-related information that is not required.

Adobe's standalone installation documentation explicitly provides examples using names such as cq5-publish-p4503.jar and cq5-author-p6754.jar .

The default ports for a traditional AEM installation are typically 4502 for Author and 4503 for Publish.

Version distinction: AEM as a Cloud Service development environments commonly use the newer aem-author-p4502.jar naming pattern. The cq5 prefix in this question reflects the traditional Quickstart naming convention and is appropriate among the supplied choices.
