    GCP ACE · Question 16 · Domain 2.3: Planning and configuring data storage options

    You are designing the database backend for a global inventory management system. The system requires relational database semantics (ACID transactions, SQL queries) but must scale horizontally to handle tens of thousands of reads and writes per second globally, with strong consistency across multiple continents.

    Which GCP database service should you choose?

    Answer options:

    A.

    Cloud SQL

    B.

    Cloud Spanner

    C.

    Cloud Bigtable

    D.

    Firestore

    How to approach this question

    Identify the service that combines relational features (SQL, ACID) with global horizontal scalability.

    Full Answer

    B.Cloud Spanner✓ Correct
    Cloud Spanner is the only enterprise-grade, globally-distributed, and strongly consistent relational database service built for the cloud specifically to combine the benefits of relational database structure with non-relational horizontal scale.

    Common mistakes

    Choosing Cloud SQL for global write scalability, or Bigtable when SQL/ACID is required.
