Professional Cloud Architect

A new relational system starts regional but is contractually required to scale to global, strongly-consistent OLTP within a year. Which database avoids a disruptive re-platform later?

A critical database requires an RPO of a few minutes and an RTO under one hour at reasonable cost. Which DR design BEST fits?

A stateless web tier must scale horizontally and tolerate instance loss behind a load balancer. Where should session state be kept?

An application must survive a full zone outage within a region using identical, autoscaling VMs. What should be designed?

Telemetry arrives at millions of writes per second and needs low-latency reads at petabyte scale. Which database should be selected?

Two services must communicate asynchronously so a consumer spike or failure never blocks the producer. Which service connects them?

A gaming backend has unpredictable global spikes, must scale instantly, keep latency low worldwide, and minimize idle cost, with state externalized. Which architecture is BEST?

For a regional OLTP app needing managed PostgreSQL with automated backups and zone-redundant HA at moderate scale, which service is the best default?

Which compute-selection heuristic aligns with Google Cloud best practice for a new workload with no special constraints?

A very large dataset must move to Cloud Storage, but available bandwidth would take months to transfer it online. Which option is appropriate?
