KCNA Cloud Native Observability Practice Question
Which THREE are responsibilities of the OpenTelemetry project? (Select three.)
⚠ Common exam trap
KCNA often tests the misconception that OpenTelemetry stores or visualizes data, when it is strictly a collection, standardization, and transport layer.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Provide instrumentation libraries
Option C is correct because OpenTelemetry provides language-specific instrumentation libraries (for Java, Python, Go, JavaScript, .NET, etc.) and APIs/SDKs that generate traces, metrics, and logs. Option D is correct because OpenTelemetry defines vendor-neutral specifications and semantic conventions for telemetry data, including the OTLP wire protocol, so signals are portable across tools. Option E is correct because the OpenTelemetry Collector is a vendor-agnostic component that receives, processes, and exports telemetry via receivers, processors, and exporters. Option A is not a responsibility of OpenTelemetry itself; visualization is handled by backends such as Jaeger, Prometheus, Grafana, or commercial APM UIs. Option B is also not a responsibility of OpenTelemetry; long-term storage is provided by backend observability platforms, not by the OpenTelemetry project.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Visualize telemetry data
Why it's wrong here
OpenTelemetry produces and exports telemetry; visualisation belongs to backends such as Jaeger, Prometheus or Grafana, which consume OTLP data. Visualisation would be an OpenTelemetry responsibility only if it shipped its own analysis UI, which it does not.
- ✗
Store long-term telemetry data
Why it's wrong here
OpenTelemetry generates, collects and exports telemetry; it defines APIs, SDKs and the OTLP wire protocol, but deliberately provides no storage backend. Persistence is delegated to observability platforms such as Prometheus, Jaeger or commercial vendors. It is tempting because the Collector's exporter pipeline appears to terminate somewhere, yet that endpoint is a separate system, not part of the project's remit.
- ✓
Provide instrumentation libraries
Why this is correct
OpenTelemetry ships language-specific instrumentation libraries that generate telemetry for common frameworks without manual coding, satisfying the stem's requirement for project responsibilities. These libraries emit spans, metrics and logs via the OpenTelemetry API, complementing the specification and collector rather than replacing them.
- ✓
Define a standard for telemetry data
Why this is correct
OpenTelemetry's core remit includes specifying a vendor-neutral data model and protocol for traces, metrics and logs, so telemetry from any source is comparable. Defining that standard satisfies the stem's requirement, distinct from providing SDKs or running a backend.
- ✓
Provide a vendor-agnostic Collector
Why this is correct
The Collector is a vendor-neutral binary that receives, processes and exports telemetry via the OpenTelemetry Protocol, satisfying the stem's vendor-agnostic constraint. It decouples instrumentation from backends, so applications emit OTLP and operators reconfigure exporters without code changes. This is a core project deliverable, not a third-party integration.
