A global fintech enterprise is designing its cloud architecture on Google Cloud for a mission-critical order execution platform. The solution requires a relational database capable of handling high-frequency transactional writes with multi-region strong consistency and 99.999% availability SLA. Additionally, the architecture must connect the on-premises trading engine to Google Cloud via a low-latency, dedicated private connection requiring 20 Gbps of bandwidth with high availability. Which TWO architectural decisions should the cloud architect make to satisfy these technical requirements? (Select TWO.)
- Deploy multi-region Cloud Spanner database instances to support globally consistent, highly available transactional workloads.Cevap
- Provision redundant Dedicated Interconnect connections at two distinct edge facilities to establish high-throughput, low-latency hybrid connectivity.Cevap
- CProvision an HA Cloud VPN gateway with multiple active-active IPsec tunnels to aggregate throughput for the 20 Gbps on-premises connection.
- DDeploy a Cloud SQL for PostgreSQL primary instance with cross-region read replicas to handle multi-region synchronous transactional writes.
- EDeploy Google Kubernetes Engine (GKE) clusters with single-zone nodepools and manual failover scripts to minimize control plane cost and operational complexity.
Cevap
The platform requires deploying multi-region Cloud Spanner instances for globally consistent relational transactions and provisioning redundant Dedicated Interconnect links to meet the 20 Gbps hybrid throughput requirement.
Cloud Spanner satisfies the multi-region relational database requirement with strong consistency and 99.999% SLA. Dedicated Interconnect provides the required 20 Gbps high-bandwidth, low-latency connection between on-premises datacenters and Google Cloud.
