1Z0-997-26 Cloud Native Architecture Practice Question
You are implementing distributed tracing across multiple microservices running on OKE. You need to capture trace data from incoming API Gateway requests, through service mesh sidecars, down to the application pods, and export it to an open-standards tracing backend. Which architectural components should you configure?
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
✓
W3C Trace Context header propagation across API Gateway, OCI Service Mesh Envoy proxies, and OpenTelemetry SDKs in applications.
OCI API Gateway, OCI Service Mesh (Envoy proxies), and application OpenTelemetry (OTel) SDKs can be configured to propagate W3C trace context headers and export traces to an OTel-compatible collector.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Kubernetes Liveness probes configured with HTTP GET request headers.
Why it's wrong here
Incorrect. Liveness probes check container health, not distributed tracing.
- ✗
OCI Audit log queries combined with Object Storage bucket lifecycle rules.
Why it's wrong here
Incorrect. Audit logs track control plane actions, not application-level distributed tracing.
- ✗
OCI Notifications service broadcast topics configured with JSON log forwarding.
Why it's wrong here
Incorrect. Notifications handles alerts, not distributed tracing propagation.
- ✓
W3C Trace Context header propagation across API Gateway, OCI Service Mesh Envoy proxies, and OpenTelemetry SDKs in applications.
Why this is correct
Correct. W3C Trace Context headers ensure trace continuity across API Gateway, Service Mesh, and application code.
