Why can Grafana panel visibility not be treated as an access-control policy?
Select an answer to reveal the explanation.
Short Explanation
Hiding a panel only changes what you see, not who can read the data. You still need the source system's permissions to access the underlying data.
Full Explanation
Panel visibility is presentation, not access control. Hiding a panel changes what is displayed, not who is authorised to read the underlying data, which remains governed by the source system's permissions. Anyone able to query the data source can retrieve the data whatever the dashboard renders. The Instana-only claim is wrong because this holds for every data source. The refresh-reset claim is wrong because visibility settings persist; the objection is conceptual. The administrator-rights claim is wrong because required rights are not the point. For the exam, enforce access at the data source, not in the visualisation layer.
