What they're testing: Stateful allow/deny by priority, direction, and tags/service accounts

Compare Cloud Run, Cloud Functions, and GKE.Medium

What they're testing: Container serverless vs event functions vs full Kubernetes orchestration

What are the GCS storage classes?Easy

What they're testing: Standard, Nearline, Coldline, Archive chosen by access frequency

How does GKE Autopilot differ from Standard?Medium

What they're testing: Google-managed nodes and ops vs self-managed node pools

What is a Shared VPC and why use it?Hard

What they're testing: Central network project shared to service projects for centralized governance

How do you partition and cluster BigQuery tables?Medium

What they're testing: Partition by date and cluster by columns to cut scanned bytes and cost

Explain IAM roles: primitive, predefined, and custom.Medium

What they're testing: Broad legacy roles vs granular Google-defined vs tailored roles

How would you make a Compute Engine deployment highly available?Medium

What they're testing: Regional MIG across zones + load balancer + health checks + autoscaling
