Which of the following requirements is necessary for the Dynatrace OneAgent?

The requirement that the Dynatrace OneAgent needs to be installed on the host that runs the application is essential because the OneAgent is designed to monitor applications and their environments effectively. By being installed directly on the host, the OneAgent gains access to the full context of the applications it is monitoring, including system metrics, application performance, resource usage, and other crucial data. This local installation ensures that the agent can gather comprehensive telemetry and analyze the performance at a granular level.

Installing OneAgent on the host enables it to effectively communicate with the Dynatrace platform for real-time analysis and monitoring, as it needs to interact closely with the application and its underlying infrastructure. This approach allows Dynatrace to provide deep insights into application performance and user experience, which would not be possible if the agent were installed elsewhere or not at all.

The other choices do not align with the operational requirements of Dynatrace OneAgent. For example, while it can support various environments, installation on a host is a fundamental requirement for functionality.
