An agent installation completed without errors, but the host does not appear in Instana. What does this most likely indicate?
Select an answer to reveal the explanation.
Short Explanation
Installed and connected are two different states. When a host installs cleanly but doesn't show up, you've got a connectivity or credential problem. Check outbound network, the backend endpoint, and the agent key.
Full Explanation
The correct answer is the option stating that the agent cannot reach the backend because of network restrictions, an incorrect endpoint, or an invalid agent key. A host that installs cleanly but never appears has completed the local step and failed the remote one. Blocked outbound traffic, a mistyped backend endpoint, and a wrong or revoked agent key are the usual causes. The option claiming that the installation actually failed and the installer reported success incorrectly is wrong because the installer reports on local file and service operations accurately; it simply does not test the connection. The option saying that host agents do not appear in the interface until a dashboard is created for them is wrong because discovered hosts appear automatically without any dashboard being created. The option requiring a host restart before any agent can register is wrong because a restart is not generally required for registration. For the exam, treat a missing host after a clean install as a connectivity or credential problem.
