- Model answer
- It is not good news; it is the shape of a telemetry problem. Run a depth probe: on a Windows host, spawn a chain that writes a distinctively named file, then confirm in the console that you can see the writing process, its parent, and both command lines. A bad result is the host being present and the activity absent, or present with the process name but no command line or parent — a fleet reporting heartbeats and nothing behavioural looks identical to a healthy one on any dashboard.
- Why, and what the wrong answers get wrong
- The distribution is the clue: 150 Windows hosts producing zero alerts while eight Linux servers produce four is not a plausible threat distribution, it is a plausible telemetry distribution. A candidate who answers 'good news, quiet estate' has made the single most consequential mistake available in this domain. A candidate who answers 'check agent health' has not understood that agent health is exactly what is misleading them. The depth probe is the habit the course installs and the reason this item exists.
- The judgement being assessed
- Whether the candidate distrusts a green dashboard when the data distribution contradicts it, and whether they know a concrete, repeatable check rather than a category of check.
