1Z0-997-26 Cloud Native Architecture Practice Question
You are configuring an OCI API Gateway deployment to secure a backend microservice running on OKE. You need to implement token-based authentication where the API Gateway validates a JSON Web Token (JWT) issued by an external identity provider before routing the request. Where should you configure this validation?
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
✓
Within an OCI Functions-based custom authorizer or native JWT validation block in the API Gateway deployment specification.
OCI API Gateway supports custom authenticators and native JWT validation policies directly on the deployment routes to validate authorization headers before forwarding requests to backends.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Inside an OCI Events rule matching the incoming HTTP request payload.
Why it's wrong here
OCI Events reacts to resource state changes, it does not sit inline to intercept and validate HTTP request tokens.
- ✓
Within an OCI Functions-based custom authorizer or native JWT validation block in the API Gateway deployment specification.
Why this is correct
OCI API Gateway supports native JWT validation policies that check issuer, audience, and signature, as well as custom authorizer functions.
- ✗
By attaching an OCI IAM policy to the target VCN subnet route table.
Why it's wrong here
OCI IAM policies control access to OCI control-plane and resource APIs, not HTTP header JWT validation for application traffic.
- ✗
Inside the Ingress Controller configuration manifest deployed on the OKE cluster.
Why it's wrong here
While Ingress controllers can handle authentication, validating at the API Gateway layer prevents unauthorized traffic from hitting the VCN backend entirely.
