Google Cloud Professional Cloud Architect PCA — Topic 1 Question 218

Question

You are deploying a critical application with a stateless, containerized frontend on Cloud Run and a Cloud SQL for PostgreSQL backend. The application experiences unpredictable traffic spikes, and the business requires the ability to immediately roll back a failed deployment to the last known good state. You need to apply a deployment strategy that aligns with Site Reliability Engineering (SRE) principles for both the application code and the database schema updates, while meeting the business's requirements. What should you do?

Accepted Answer

Correct answer: C. The correct answer is C. Option C: Separate CI/CD pipelines for database schema migrations from application deployments. When deploying a new Cloud Run revision, use gradual traffic split. Cloud Run runs stateless containers serverlessly and scales to zero, minimizing operational overhead. This option decouples the components so they scale independently and absorb load spikes.
