Zorluk: OrtaCreating Conceptual, Logical, and Physical Architectures

An enterprise energy grid operator is designing a smart meter telemetry and analytics platform on Google Cloud. The conceptual architecture defines three main tiers: a real-time ingestion tier for 10 million smart meters, a streaming processing tier for time-series anomaly detection, and a secure storage tier for time-series analytics that prevents data exfiltration. Which TWO physical Google Cloud service and security configuration choices correctly translate these logical requirements into an optimal physical architecture? (Select TWO)

  1. Provision Cloud Pub/Sub for high-throughput event ingestion, Cloud Dataflow for stream processing, and Cloud Bigtable for scalable time-series data storage.Cevap
  2. Configure VPC Service Controls perimeter encompassing the project resources to isolate managed storage and compute services from unauthorized data exfiltration.Cevap
  3. C
    Deploy Cloud Spanner as the primary raw telemetry database to handle high write volume and relational joins across multiple geographic regions.
  4. D
    Rely strictly on fine-grained IAM service account roles without network perimeter security to enforce data exfiltration boundaries.
  5. E
    Deploy a dedicated GKE cluster running custom Apache Flink pods for micro-batch telemetry processing to reduce operational complexity.

Cevap

The optimal physical architecture pairs Cloud Pub/Sub, Cloud Dataflow, and Cloud Bigtable for high-scale time-series telemetry ingestion, processing, and storage, while leveraging VPC Service Controls to prevent data exfiltration beyond the security perimeter.
Combining Cloud Pub/Sub, Cloud Dataflow, and Cloud Bigtable maps the logical streaming architecture directly to GCP native services optimized for heavy time-series workloads. Adding VPC Service Controls establishes an effective physical boundary against data exfiltration across managed services.

Adım Adım Çözüm

1
Analyze high-throughput time-series requirements
Identify Pub/Sub, Dataflow, and Bigtable as the native GCP physical stack for streaming IoT and telemetry workloads.
10 million smart meters generate continuous high-frequency metrics requiring low-latency writes and time-series key design.
2
Evaluate perimeter security constraints
Select VPC Service Controls to enclose managed services.
Conceptual exfiltration prevention requirements cannot be satisfied by IAM alone; network-level service perimeters are required.
