Which check best confirms that a newly installed agent is working?
Select an answer to reveal the explanation.
Short Explanation
The only proof that matters is data arriving. Seeing the host appear in the Instana interface and report current telemetry confirms the agent is actually working. Everything else only confirms a step along the way.
Full Explanation
The best confirmation is seeing the host appear in the Instana interface and report current telemetry. That demonstrates the whole path end to end: the agent runs, its sensors collect, and the connection to the backend works. The installation command exiting without an error is not enough because it covers only the local installation and not the connection. The presence of the agent's configuration file on the host is not enough because a configuration file on disk says nothing about whether the agent is running or reporting. SSH reachability from the monitoring team's workstation is not enough because it is a different network path with different rules from the agent's outbound connection. For the exam, verify agents by observing data in the backend rather than by local indicators.
