Google Cloud Professional Cloud Database Engineer — Question 94

Your company is developing a new global transactional application that must be ACID-compliant and have 99.999% availability. You are responsible for selecting the appropriate Google Cloud database to serve as a datastore for this new application. What should you do?

Answer options

• A. Use Firestore.
• B. Use Cloud Spanner.
• C. Use Cloud SQL.
• D. Use Bigtable.

Correct answer: B

Explanation

Cloud Spanner is designed for high availability and is ACID-compliant, making it the ideal choice for applications requiring both characteristics. Firestore and Cloud SQL do not guarantee the same level of availability and scalability needed for global transactional applications, while Bigtable is not designed for ACID transactions.
