An enterprise fintech startup is launching a stateless REST API microservice to process payment authorization requests. The service experiences unpredictable HTTP traffic spikes during stock market trading hours but receives virtually zero traffic overnight and on weekends. The architecture team must minimize overall infrastructure costs by allowing compute resources to scale down to zero when idle, while also minimizing operational maintenance overhead. Which architectural design best satisfies these business and technical requirements?

A renewable energy utility enterprise is migrating its smart grid telemetry platform to Google Cloud. The design requires connecting two primary on-premises data centers to a centralized Shared VPC host network in GCP to handle a sustained ingress throughput of 15 Gbps with a strict 99.99% uptime Service Level Agreement (SLA). Furthermore, analytics applications located in separate spoke VPCs peered to the Shared VPC host network must exchange data directly with on-premises databases. Which hybrid network architecture correctly satisfies both the SLA, bandwidth capacity, and VPC peering routing constraints?

A fashion retail enterprise operates an order fulfillment pipeline that renders personalized PDF invoices upon user checkout. The workload is completely stateless and experiences highly unpredictable traffic, ranging from zero requests during off-peak hours to sudden bursts of 300 requests per minute during promotional flash sales. The lead architect needs to select a compute architecture that minimizes overall infrastructure costs by scaling to zero during idle periods while eliminating container orchestration cluster management overhead. Which solution should the architect choose?

A global healthcare organization is designing a cloud architecture to process batch genomic dataset archives uploaded by partner laboratories. The dataset uploads occur unpredictably throughout the day, with volume fluctuating between zero and several hundred uploads per hour. Each processing task runs a containerized data-transformation binary that takes between 10 and 40 minutes to complete. The business goal is to minimize operational overhead and compute costs by avoiding charges for idle infrastructure while ensuring processing starts within minutes of upload. Additionally, raw uploaded archives must be preserved for compliance for five years, but are rarely accessed after the initial 30 days. Which TWO architectural recommendations should you make to meet these business and cost requirements? (Select TWO.)

A financial analytics company executes scheduled daily risk-assessment batch computations for corporate clients. The batch job runs for approximately two hours every night, requiring dynamic scaling based on client volume. The application stores financial ledger transaction records in a standard relational database with regional availability requirements. Currently, the infrastructure relies on continuously running Virtual Machines and over-provisioned database instances, incurring high idle costs. You need to redesign the solution architecture to minimize compute and database costs while meeting technical requirements. Which two architectural decisions should you recommend? (Select TWO.)

A financial services organization needs to establish private, SLA-backed hybrid connectivity between its on-premises data center and a Google Cloud Virtual Private Cloud (VPC). The solution must support a throughput requirement of 1 Gbps without traversing the public internet. The organization does not have a presence in a Google colocation facility. Which Google Cloud connectivity solution should the cloud architect choose?

An e-commerce company operates a real-time recommendation engine microservice on Google Cloud Run. The Site Reliability Engineering (SRE) team defines a Service Level Objective (SLO) requiring 99.9% of valid requests to return successful HTTP responses over a rolling 30-day window. During flash sales, transient traffic spikes occasionally consume substantial portions of the monthly error budget within a few hours before static alerts trigger, leading to exhaustion of the budget without timely intervention. Which monitoring and alerting configuration should the team implement in Cloud Monitoring to detect fast budget consumption before the error budget is fully depleted?

An aerospace satellite operations company hosts its ground telemetry monitoring system on Google Cloud. The primary workload runs in region `europe-west1`, utilizing Compute Engine Managed Instance Groups (MIGs) for application servers and Cloud SQL for PostgreSQL for critical mission metadata. To comply with regulatory requirements, the system requires a Disaster Recovery (DR) warm standby in `europe-west4` capable of achieving a Recovery Point Objective (RPO) of near-zero and a Recovery Time Objective (RTO) under 15 minutes. A regional catastrophe causes a complete failure of `europe-west1`. Which set of disaster recovery execution steps should the cloud architect specify in the failover runbook?

A financial services organization is automating its multi-region environment deployment pipeline using Terraform executed by Cloud Build. To adhere to Google Cloud operational reliability and security best practices, the pipeline must prevent state file corruption during concurrent automated runs and enforce least privilege during resource provisioning. The deployment worker currently needs to provision compute and network resources across multiple target projects. How should the Site Reliability Engineering (SRE) team configure the Terraform state storage and execution permissions?

An automotive telematics enterprise needs to establish hybrid connectivity between its on-premises data center and a Google Cloud VPC. The business requirement dictates a continuous, private Layer 3 connection with a bandwidth requirement of 8 Gbps for real-time telemetry streaming, without routing traffic over the public internet. The architecture must minimize ongoing connectivity and data transfer costs while fulfilling these bandwidth and security requirements. Which hybrid networking strategy should the cloud architect recommend?

A global logistics platform is migrating its backend operational workloads to Google Cloud. The system consists of stateless HTTP REST microservices with highly variable, bursty traffic patterns, alongside a $300\text{ GB}$ relational database supporting standard regional ACID transactions. The company's primary business objective is to minimize baseline infrastructure costs and operational management overhead. Which TWO architecture decisions should you recommend to achieve these cost optimization goals? (Select TWO.)

An enterprise organization is deploying a major application update to a microservice hosted on Google Cloud Run that interacts with a Cloud SQL for PostgreSQL database. During a blue-green deployment, the team executes a database migration script that removes deprecated table columns required by the existing (blue) version as soon as the new (green) version is deployed. As a result, users routed to the blue deployment experience high error rates during the rollout. Which release management strategy should the cloud architect implement to prevent service disruptions during future database migrations?

An international retail company is migrating its regional order processing application to Google Cloud. The application relies on a standard relational database with strict ACID transaction requirements, storing 2 TB of data and handling a predictable peak load of 4,000 IOPS. The business requires high availability across zones within a single GCP region, but explicit business constraints require minimizing monthly operational overhead and infrastructure costs. Multi-region redundancy is explicitly out of scope. Which database architecture should you recommend?

An international financial institution is designing a core transaction platform on Google Cloud. The application requires a relational database capable of global multi-region active-active processing, strong transactional consistency, zero Recovery Point Objective (RPO), and an RTO of under 5 seconds during a full regional outage. Additionally, audit operations require dedicated, SLA-backed private network connectivity from an on-premises data center to Google Cloud capable of sustaining 10 Gbps dedicated bandwidth without traversing the public internet. Which architecture fulfills these high availability and connectivity requirements while adhering to Google Cloud best practices?
