Which characteristic makes a service name operationally useful?
Select an answer to reveal the explanation.
Short Explanation
Stable and recognisable. If a name changes when you redeploy or reschedule, it fails the test.
Full Explanation
The correct option is the one saying the name is stable across deployments and uses terms the responding team already uses. Stability preserves history across deployments, and recognisability removes the lookup step during an incident. The option encoding the current deployment version is wrong because embedding the version makes the name change on every release, splitting history. The option about fitting any dashboard column without wrapping is wrong because display width is a formatting concern. The option matching the current hostname is wrong because a service may move between hosts or run on many at once. For the exam, judge names by stability and recognisability.
