You need to create a private GKE cluster with Workload Identity enabled to allow pods to access Google Cloud APIs without static service account keys. What must you configure for the cluster?
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
✓
Enable Workload Identity on the cluster and set the --workload-pool flag at cluster creation
Workload Identity requires a GKE cluster with Workload Identity enabled and a Google-managed service account for the node pool or individual pods.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Enable Binary Authorization on the cluster
Why it's wrong here
Binary Authorization enforces image signing, not identity for pods.
- ✓
Enable Workload Identity on the cluster and set the --workload-pool flag at cluster creation
Why this is correct
Correct. Workload Identity is enabled via the --workload-pool flag on the cluster.
- ✗
Create a node pool with a service account that has the necessary IAM roles and assign that SA to pods
Why it's wrong here
This is the old way without Workload Identity; it requires managing keys.
- ✗
Use Cloud NAT to allow pods to communicate with Google APIs
Why it's wrong here
Cloud NAT provides outbound connectivity, not identity-based access.
