What does a deployment app consist of within Splunk?

A deployment app in Splunk is designed to manage and distribute configurations and content across multiple Splunk instances, making option B — a collection of deployment content — the correct choice. This is because a deployment app typically includes various files such as configuration files, scripts, and other elements that define how your Splunk environment should behave and what data it should handle.

Deployment apps allow for the effective management of configurations and the synchronization of settings across different instances, ensuring consistency and ease of updates. Since they are designed to deploy content to forwarders or search heads, they not only include configuration files but also any necessary supporting files, thus encapsulating a broader range of content than just configurations alone.

While application settings and user interface enhancements can definitely be part of a deployment app's functionality, they do not fully encompass what deployment apps represent within Splunk. A focused collection that includes both essential configuration files and additional content captures the comprehensive nature of a deployment app better than any singular aspect.
