Key Exam Topics

•GKE Standard vs Autopilot: Standard (manage nodes) vs Autopilot (pay per pod, Google manages nodes)

•Workload Identity: bind K8s ServiceAccount to GCP service account (no static keys)

•GKE networking: VPC-native clusters (alias IP), private clusters, shared VPC

•Node pools: system (K8s components) + user (app workloads); Spot nodes for cost savings

•GKE Autopilot: enforces security constraints, optimizes bin packing, no node management

•Cloud Armor: WAF + DDoS protection integrated with GKE Ingress/Load Balancer

•Anthos: hybrid/multi-cloud management (GKE on-premises, AWS, Azure)

Must-Know CLI Commands

bash

gcloud container clusters create prod --region us-central1 --enable-ip-alias --workload-pool=PROJECT.svc.id.goog
gcloud container clusters get-credentials prod --region us-central1
gcloud container node-pools create spot-pool --cluster prod --spot --enable-autoscaling --min-nodes 0 --max-nodes 20
gcloud iam service-accounts add-iam-policy-binding gsa@PROJECT.iam.gserviceaccount.com --role roles/iam.workloadIdentityUser --member "serviceAccount:PROJECT.svc.id.goog[NAMESPACE/KSA]"
gcloud container clusters upgrade prod --master

Exam Tips

•Autopilot: best for most teams — no node sizing decisions, enforced best practices

•Spot nodes: substantially cheaper than on-demand (exact discount range needs verification — it floats with real-time capacity, not a fixed percentage); evicted after 24hr or when Spot market needs capacity

•Node auto-provisioning: Standard mode only; creates new node pool sized to pending pod

•Private clusters: no external node IPs; requires Cloud NAT for outbound internet
