Cevap: Deploy Cloud Spanner with a multi-region instance configuration, configure Private Google Access for Compute Engine subnets, and implement a VPC Service Controls perimeter around the project resources.

Cevap

Deploying Cloud Spanner with a multi-region configuration alongside Private Google Access and VPC Service Controls fulfills all technical, high availability, and anti-exfiltration constraints.

The combination of Cloud Spanner in a multi-region deployment, Private Google Access, and VPC Service Controls addresses all stated architecture needs. Cloud Spanner delivers multi-region ACID consistency with zero data loss (

RPO = 0

), Private Google Access keeps database communication on private Google infrastructure, and VPC Service Controls prevents authorized identities from exporting data outside designated perimeter boundaries.

Adım Adım Çözüm

Evaluate database requirements for multi-region ACID transactions and RPO=0.

Cloud Spanner multi-region instance deployment is selected because it provides synchronous cross-region replication, RPO=0, and high availability (99.999% SLA).

Cloud SQL provides regional HA but uses asynchronous replication for cross-region read replicas, failing the zero RPO requirement.

Determine private routing requirements for internal Compute Engine microservices.

Private Google Access is enabled on the subnets housing Compute Engine instances.

Allows instances without public IP addresses to reach Google APIs and Cloud Spanner endpoints over internal Google network paths.

Address data exfiltration security requirements.

VPC Service Controls perimeters are configured around the project.

IAM roles grant permission to access data but cannot restrict where authorized data is written. VPC Service Controls blocks data movement to non-designated external projects or storage locations.

Cevap

1. Global multi-region relational ACID with 99.999% SLA maps to Cloud Spanner.
2. Low-latency time-series key-value IoT telemetry maps to Cloud Bigtable.
3. Mobile app real-time JSON document sync maps to Firestore.
4. Unstructured media and audit log lifecycle management maps to Cloud Storage.

Each GCP database and storage service addresses specific architectural trade-offs: Cloud Spanner for globally distributed relational ACID workloads; Cloud Bigtable for high-throughput, low-latency key-value/time-series data; Firestore for real-time mobile serverless document synchronization; and Cloud Storage for unstructured object data with lifecycle management.

Adım Adım Çözüm

Analyze global multi-region relational ACID requirements.

Cloud Spanner is the only relational GCP database service providing multi-region external consistency, ANSI SQL compatibility, and five-nines (99.999%) availability.

Traditional relational databases like Cloud SQL do not provide global multi-region horizontal scaling or 99.999% SLAs.

Analyze high-throughput IoT time-series telemetry data requirements.

Cloud Bigtable provides low-latency key-value write throughput suitable for massive IoT streaming datasets and integrates directly with BigQuery.

Relational databases cannot handle massive, continuous single-digit millisecond write loads efficiently without complex sharding.

Analyze mobile JSON document synchronization requirements.

Firestore provides serverless document storage with native client SDKs supporting offline persistence and automatic real-time listener updates.

Relational and object storage engines lack native client state synchronization and offline caching primitives.

A healthcare company provisions isolated staging environments using Terraform running in a dedicated management Virtual Private Cloud (VPC). During an automated deployment pipeline, Terraform provisions a private Google Kubernetes Engine (GKE) cluster in a target workload VPC. The cluster creation succeeds, but subsequent Terraform steps fail when attempting to deploy cluster workloads because the Terraform runner cannot communicate with the GKE control plane. Which architectural modification should the team implement to resolve this provisioning issue while adhering to Google Cloud security and reliability best practices?

Configure GKE Control Plane Authorized Networks to include the IP range of the management VPC runner subnet and ensure VPC peering or Authorized Network connectivity allows internal access to the private control plane endpoint.

Disable the private control plane endpoint and grant the Primitive Owner role to the pipeline service account so it can bypass cluster endpoint restrictions.

Peer the management VPC to an intermediate transit VPC that is already peered with the cluster VPC, relying on network transitivity for control plane reachability.

Grant the Service Account Admin role to the pipeline service account to allow dynamic generation and injection of service account keys during provisioning.

Cevap: Configure GKE Control Plane Authorized Networks to include the IP range of the management VPC runner subnet and ensure VPC peering or Authorized Network connectivity allows internal access to the private control plane endpoint.

Cevap

Configure GKE Control Plane Authorized Networks to explicitly allow the management subnet CIDR containing the Infrastructure as Code runner, ensuring secure internal network access to the private master endpoint.

The correct answer addresses private GKE cluster accessibility during automated environment provisioning. Private cluster control planes drop traffic unless the source network is explicitly authorized. Adding the management VPC runner subnet CIDR to Control Plane Authorized Networks establishes secure internal connectivity needed for automated Terraform apply steps.

Adım Adım Çözüm

Identify the cause of cluster provisioning failure

The Terraform runner cannot communicate with the private GKE control plane because the master endpoint blocks unauthorized source IP ranges by default.

Private GKE cluster control planes restrict access to authorized network ranges and internal endpoints.

Evaluate network routing and access controls

VPC Network Peering is non-transitive, meaning intermediate VPC hops will not route traffic to the control plane, while public endpoint exposure violates security posture.

GCP networking rules strictly prevent transitive peering and mandate least-privilege network access.

Authorize the runner subnet CIDR range

The IaC pipeline successfully reaches the cluster API server over internal routing to complete workload deployment steps.

Adding the runner's subnet CIDR to Control Plane Authorized Networks grants legitimate, secure deployment access.

Cevap: Configure the Terraform backend using the standard Google Cloud Storage (gcs) backend type and enable Object Versioning on the Cloud Storage bucket.

Cevap

Configure the Terraform backend using the standard Google Cloud Storage (gcs) backend type and enable Object Versioning on the Cloud Storage bucket.

The standard Google Cloud Storage (gcs) backend for Terraform natively supports state locking by utilizing GCS object generation and metageneration preconditions. When combined with GCS Object Versioning, state files are protected against concurrent modifications and accidental corruption during automated CI/CD environment deployments.

Adım Adım Çözüm

Identify the root cause of concurrent environment provisioning failures in IaC pipelines.

Concurrent pipeline runs collide when writing to the remote state file without proper state locking mechanisms.

Terraform state integrity requires exclusive lock acquisition during modifications to prevent race conditions and partial state updates.

Select the native Google Cloud API mechanism for state management in GCP.

The standard gcs backend type leverages Cloud Storage strong consistency and built-in object lock capabilities automatically.

Google Cloud Storage natively handles atomic operations and generation-based locking for Terraform state operations.

Implement state safety and recovery best practices.

Enabling Cloud Storage Object Versioning ensures previous versions of the state file are retained.

Object Versioning protects against unintended state file corruption or manual execution drift, allowing rapid rollback if needed.

Cevap

Deploy an HA VPN gateway with dual active-active IPSec tunnels and Cloud Router dynamic BGP routing in the central Hub VPC, and establish dedicated HA VPN connections from the on-premises data center to each Spoke VPC individually.

To satisfy a 2 Gbps encrypted connectivity requirement with high availability, establishing an HA VPN gateway with active-active IPSec tunnels and Cloud Router dynamic BGP routing in the Hub VPC is essential. Furthermore, because GCP VPC Network Peering is non-transitive, on-premises networks cannot reach peered Spoke VPCs through the Hub VPC; establishing direct HA VPN connections to each Spoke VPC ensures full connectivity.

Adım Adım Çözüm

Evaluate throughput and encryption requirements for hybrid connectivity.

The requirement calls for 2 Gbps encrypted throughput. A single HA VPN tunnel supports up to 3 Gbps, and active-active configuration provides topology redundancy with a 99.99% SLA.

HA VPN with Cloud Router handles dynamic BGP routing and satisfies both security and SLA targets.

Analyze transitive routing boundaries across VPC Network Peering.

VPC Network Peering does not support transitive routing. Traffic arriving from an on-premises VPN tunnel into the Hub VPC cannot be routed over the peering link into Spoke VPCs.

Direct hybrid connectivity (or gateway proxies/Network Connectivity Center) must be deployed to reach the Spoke VPCs directly from on-premises.

Cevap: Deploy a Cloud SQL for PostgreSQL instance with High Availability (HA) enabled across primary and standby zones within the region.

Cevap

The recommended solution is deploying a Cloud SQL for PostgreSQL instance configured for High Availability (HA) within the single target region.

Deploying Cloud SQL for PostgreSQL with High Availability (HA) is the optimal choice. Cloud SQL provides native relational database capabilities with ACID compliance, and its HA option automatically replicates data synchronously to a standby instance in a secondary zone within the same region (europe-west3), ensuring quick failover while keeping costs and operational overhead aligned with single-region requirements.

Adım Adım Çözüm

Analyze the functional database requirements

The application requires ACID compliance for player profiles and inventory, single-region deployment in europe-west3, and high availability across zones.

Relational data modeling with transactional guarantees is required for monetary or inventory operations.

Evaluate GCP database services based on scale and region constraints

Cloud SQL satisfies single-region relational database requirements cost-effectively. Cloud Spanner is intended for globally distributed workloads requiring cross-region consistency.

Choosing Spanner for a single-region deployment incurs unnecessary cost and architectural complexity.

Verify high availability configuration

Enabling High Availability (HA) on Cloud SQL provisions a synchronous standby instance in a second zone within the same region, providing automatic failover.

This satisfies the multi-zone availability requirement without requiring cross-region infrastructure.

Cevap: Deploy the API on Cloud Run across multiple regions behind a Global External HTTP(S) Load Balancer, and store reservation data in a multi-region Cloud Spanner instance.

Cevap

Deploying the microservice API on Cloud Run across multiple regions behind a Global External HTTP(S) Load Balancer, paired with a multi-region Cloud Spanner instance for database storage.

Cloud Run is a fully managed serverless platform for containerized stateless applications that scales automatically and eliminates container cluster administration. Fronted by a Global External HTTP(S) Load Balancer, incoming requests are efficiently distributed to regional Cloud Run instances. Cloud Spanner with a multi-region deployment configuration delivers external consistency and multi-region synchronous replication with zero RPO, satisfying strict transactional reservation requirements.

Adım Adım Çözüm

Evaluate compute requirement for zero cluster management overhead and serverless scaling

Cloud Run allows deploying stateless containerized APIs without managing GKE clusters or Compute Engine virtual machines.

The requirement explicitly states that operational overhead from container cluster management must be eliminated.

Evaluate database requirement for multi-region zero-RPO synchronous consistency

Cloud Spanner configured across multiple regions uses Paxos consensus to provide strong consistency and synchronous multi-region replication.

Cloud SQL is limited to single-region regional HA, whereas Cloud Spanner natively supports multi-region zero-RPO transactional consistency.

Combine compute and database components with global traffic routing

Global External HTTP(S) Load Balancer routes client requests to the nearest healthy Cloud Run region, which queries the multi-region Cloud Spanner backend.

This combination ensures high availability (99.99% stem target) and low latency worldwide.

Cevap: Cloud SQL for PostgreSQL deployed with regional High Availability (HA) enabled

Cevap

Cloud SQL for PostgreSQL deployed with regional High Availability (HA) enabled

Cloud SQL for PostgreSQL with regional High Availability (HA) provides a fully managed ACID-compliant relational database with automatic cross-zone failover within a single region. It easily handles moderate throughput requirements while optimizing costs and architectural simplicity.

Adım Adım Çözüm

Analyze technical and operational constraints

The target workload requires a single-region relational database with full ACID compliance, standard SQL interface, high availability across zones, and modest throughput (1,200 TPS).

Identifying the scope (single region) and data model (relational SQL) narrows down GCP database options.

Compare database services for single-region relational workloads

Cloud SQL is optimized for single-region relational databases. Cloud Spanner is engineered for multi-region global distribution and massive horizontal scaling, making it cost-prohibitive for standard single-region needs.

Matching workload scale to resource capabilities ensures cost-effective architecture.

Verify high availability configuration

Enabling regional HA on Cloud SQL provisions a primary and standby database instance across distinct zones with automatic synchronous replication and failover.

This directly fulfills the high availability requirement without requiring complex multi-master replication.
