✍️ Sample Google Cloud Certified - Professional Cloud Architect Questions & Answers
1. A Kubernetes deployment on GKE needs to ensure pods are spread across multiple zones for high availability. Which feature achieves this?
Topology Spread Constraints control how pods are distributed across topology domains like zones, ensuring high availability.
2. Which Google Cloud resource hierarchy level is the recommended attachment point for Organization Policy constraints that must apply universally with no exceptions?
Policies attached at the organization node apply to all folders, projects, and resources within the organization and cannot be overridden lower in the hierarchy.
3. What is the recommended practice for managing service account keys in Google Cloud?
Google recommends avoiding user-managed service account keys entirely by using Workload Identity Federation or attaching service accounts to resources.
4. A team needs to run a GPU-accelerated ML training job that takes 8 hours and can tolerate restarts. How should they minimize cost?
Spot/preemptible GPU VMs cost up to 60-91% less than on-demand; checkpointing ensures restarts don't lose progress, making them viable for long fault-tolerant training jobs.
5. An architect must design a system where a batch ML training job reads from BigQuery and writes model artifacts to Cloud Storage, running nightly. What is the best orchestration tool?
Cloud Composer (managed Airflow) provides robust DAG-based orchestration with built-in BigQuery and GCS operators, retry logic, and dependency management for complex batch workflows.
6. The focus of the least privilege principle is:
Explanation: Making sure that your users have access to only what is necessary to perform their job obligations is the aim of the least privilege.
