How can you check if Infrastructure Monitoring mode is enabled in Dynatrace OneAgent?

The correct choice involves using the command ./oneagentctl --get-infra-only, which is explicitly designed to retrieve the current configuration of the OneAgent with respect to Infrastructure Monitoring mode. This command allows users to verify whether the Infrastructure Monitoring feature is enabled or disabled by returning the relevant status information.

In the context of Dynatrace, understanding the operational mode of OneAgent is crucial as it determines how the agent collects and reports data regarding your infrastructure. By using the retrieval command, users can confirm the agent's current state and ensure it is configured correctly for their monitoring needs.

The other options provided focus on setting configurations or removing tags, which do not provide information about the status of Infrastructure Monitoring mode directly. They serve different functionalities and won’t yield the necessary information needed to check the monitoring mode.
