Google Cloud Professional Cloud Developer — Question 341

You have a Cloud Run service that connects to a Cloud SQL Enterprise edition database instance using the default Cloud SQL connection. You need to enable more than 100 connections per Cloud Run instance. What should you do?

Answer options

• A. Increase the queries per minute quota limit of the Cloud SQL Admin API.
• B. Increase the max_connection flag in Cloud SQL for PostgresSQL.
• C. Upgrade to Cloud SQL Enterprise Plus edition.
• D. Use Cloud SQL Auth Proxy in a sidecar.

Correct answer: D

Explanation

Using the Cloud SQL Auth Proxy in a sidecar enables more than 100 connections by handling the connection limit effectively. The other options do not provide a feasible solution for increasing the connection limit for Cloud Run instances; simply raising quotas or flags does not address the inherent restrictions of the Cloud Run architecture.
