A global pharmaceutical enterprise is migrating its core clinical trial telemetry platform to Google Cloud. The architecture must establish private hybrid connectivity between on-premises data centers and GCP with sustained bandwidth exceeding under a high-availability SLA. Additionally, the core transactional data store requires multi-region deployment with synchronous replication to ensure zero Recovery Point Objective (RPO) and high availability during regional outages. Which TWO architectural decisions should the Cloud Architect implement to satisfy these technical and availability requirements?
- Provision Dedicated Interconnect with redundant 10 Gbps circuits between the on-premises data center and the Google Cloud VPC.Answer
- Deploy Cloud Spanner with a multi-region instance configuration for the transactional database layer.Answer
- CConfigure an HA Cloud VPN gateway with multiple active-active IPsec tunnels to route the hybrid workload.
- DDeploy Cloud SQL for PostgreSQL with a cross-region read replica and configure automated failover.
- EProvision a multi-zonal Google Kubernetes Engine (GKE) cluster with Anthos Service Mesh to host stateless REST API endpoints.
Answer
The Cloud Architect must provision Dedicated Interconnect with redundant 10 Gbps circuits and deploy Cloud Spanner with a multi-region instance configuration.
Dedicated Interconnect provides private, high-bandwidth (>15 Gbps) physical connectivity under strict SLAs, while Cloud Spanner's multi-region synchronous consensus algorithm satisfies zero RPO and high availability requirements across regions.
