Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
To replace Prometheus for metric collection
Why it's wrong here
The collector complements Prometheus but does not replace it; Prometheus can still be used for metrics.
- ✓
To receive, process, and export telemetry data
Why this is correct
The collector acts as a pipeline to handle telemetry data from multiple sources and send to one or more backends.
- ✗
To store traces and metrics long-term
Why it's wrong here
The collector is an intermediary; it forwards data to storage backends like Jaeger or Prometheus.
- ✗
To generate traces for applications
Why it's wrong here
The collector does not generate data; it processes and exports data from instrumented applications.
