What is wrong with giving many services identical names?
Select an answer to reveal the explanation.
Short Explanation
If several services share the same name, an alert or trace can't tell you which one to fix. You need distinct names so you can identify the actual service that produced the signal.
Full Explanation
Naming exists to distinguish. Collapsing several services into one label removes the information needed to route an alert or interpret a trace. Distinct components can no longer be told apart, so an alert or trace cannot be attributed to the service that actually produced it. The option saying Instana rejects duplicate service names during discovery is wrong because the platform does not enforce uniqueness. The option saying identical names prevent services from being included in dashboards is wrong because they still appear, just indistinguishably. The option saying duplicate names cause telemetry to be discarded is wrong because telemetry is still collected. For the exam, require names that are both meaningful and distinct.
