GCP Professional Cloud Architect Practice Question

Your architecture team must select a managed relational database service on Google Cloud for a new globally distributed e-commerce platform. Requirements include multi-region availability at 99.999 %, external consistency for financial transactions, automatic petabyte-scale growth, and cost limits. Finance, operations, and developer stakeholders all need to understand why the final choice is made before funding a proof-of-concept. Which decision-making technique best provides a transparent, repeatable way to quantify how each option meets the agreed KPIs?

  • Conduct a white-board architecture review with senior engineers and choose the option that receives consensus support.

  • Build a small proof-of-concept for each database and select the one that shows the highest throughput in benchmarks.

  • Create a weighted decision matrix that scores Cloud SQL, Spanner, and AlloyDB against stakeholder-approved KPIs, then choose the highest-scoring service.

  • Randomly route a portion of production traffic to each database (A/B test) and select the option with the best real-time customer satisfaction metrics.
