In AEM, Lucene is often used for indexing due to its powerful full-text search capabilities, and it also supports asynchronous indexing. Asynchronous indexing allows the system to handle other tasks while indexing is being processed in the background, which can improve performance and scalability. This is especially useful when multiple properties need to be indexed without impacting the immediate response times of the system. Therefore, when a developer needs to enable the indexing of multiple properties asynchronously, a Lucene index is the most suitable choice.

In the context of AEM as a Cloud Service, a "Golden Master" typically refers to the production-ready, main branch within the Cloud Manager Git Repository. This repository is used to manage and deploy code to AEM Cloud Service environments. It is considered the source of truth for the codebase that is used to build, test, and deploy AEM applications in the cloud.

Experience Fragments in AEM can be exported to Adobe Target, and the default format for this export is HTML. When Experience Fragments are exported to Adobe Target, they are typically used for personalization and A/B testing. HTML is the format that is readily usable within Adobe Target to create variations of a page or a component for these testing purposes.

• XML (Option B) and JSON (Option C) are not the default formats for exporting Experience Fragments to Adobe Target. While they can represent structured data, for the purposes of visual personalization in Adobe Target, the HTML format is used because it can directly represent the markup required for the content to be rendered in a browser.

The Discovery Service is an offloading-related service used by each AEM instance to connect to AEM Topology Connector. The Discovery Service is part of the Sling Discovery framework, which is responsible for detecting and managing the topology of AEM instances. It enables instances to discover each other and establish a clustered topology, which is essential for load-balancing, failover, and other distributed operations.

• Option A, "Cluster Service," is not a standard term used in AEM for connecting to the Topology Connector.
• Option C, "Topology Connector Service," is a slightly misleading term; the correct term is Discovery Service, which performs the role described.
