GCP Professional Cloud Architect Practice Question

An international retailer is rebuilding its e-commerce platform on Google Cloud. The site must 1) absorb sudden seasonal traffic surges up to 20× baseline with minimal operations, 2) serve pages with 95th-percentile latency under 500 ms for customers worldwide, 3) keep each shopper's cart immediately consistent across regions, and 4) avoid paying for idle capacity. Which architecture best satisfies these business requirements?

  • Run the services on regional GKE clusters fronted by a TCP load balancer, use Cloud SQL with cross-region read replicas for carts, and enable Cloud CDN for static assets.

  • Use Compute Engine managed instance groups with autoscaling per region, replicate MySQL on VMs asynchronously across regions, and cache content with Cloud CDN.

  • Deploy stateless microservices in Cloud Run behind a global external HTTP(S) Load Balancer with Cloud CDN, and store transactional data in a multi-region Cloud Spanner instance.

  • Host the application in a single-region App Engine standard environment, store data in Firestore (Datastore mode), and improve performance with Cloud CDN and autoscaling.
