Which TWO services should you include in the architecture? (Select TWO)
Answer options:
A.
Cloud Run
B.
Cloud SQL
C.
Cloud Spanner
D.
Firestore
E.
App Engine Standard
How to approach this question
Select the compute service mentioned in the prompt, and the only GCP database that is both relational and horizontally scalable.
Full Answer
Cloud Run
Cloud Spanner
The architecture requires Cloud Run for the frontend microservices. For the backend, the requirement for ACID transactions, relational schemas, and horizontal scalability points exclusively to Cloud Spanner. Cloud SQL cannot scale horizontally for writes, and Firestore/Bigtable are NoSQL.
Common mistakes
Selecting Cloud SQL (B) - it fails the horizontal scalability requirement.
