A customer has a business requirement to trigger a specific workflow in author whenever there is a change to a particular type of node in AEM. Which functionality should the Business Practitioner recommend?

Workflow Launchers are the designated AEM functionality for automatically starting a workflow in response to repository events. A launcher can be configured to monitor a specific path in the content repository for changes (creation, modification, or deletion) to nodes of a particular type (nodetype). When the defined event occurs on a matching node, the launcher automatically triggers a specified workflow model. This directly fulfills the business requirement to initiate a workflow upon a change to a specific node type on the author instance.

A. Launches: This feature is used to create and manage future versions of web pages for subsequent review and publication, not for triggering workflows based on general node changes.
C. DAM update asset workflow: This is a specific, pre-configured workflow that runs on asset updates. It is an example of an automated workflow, not the underlying functionality used to create such triggers.
D. Activation model workflow: This is not a standard AEM term. While workflows are used for content activation, "Activation model workflow" does not describe the mechanism for triggering them.

Adobe Experience Manager as a Cloud Service Documentation, "Starting Workflows when a Node is Changed": "A workflow launcher monitors a content repository for changes to nodes at a specific location. When a node is changed, the workflow launcher starts a workflow for that node... The launcher configuration identifies the node to monitor by its path and node type."
