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 Persistent Volume Claims with Block Storage
Why it's wrong here
Incorrect. PVCs handle storage provisioning, not authentication.

Why it's wrong here
Incorrect. Vault is for managing encryption keys and secrets, not for authenticating pods to IAM.

OCI IAM Workload Identity for OKE
Why this is correct
