Topic 1 Question 44
You are designing a highly available (HA) Cloud SQL for PostgreSQL instance that will be used by 100 databases. Each database contains 80 tables that were migrated from your on-premises environment to Google Cloud. The applications that use these databases are located in multiple regions in the US, and you need to ensure that read and write operations have low latency. What should you do?
Deploy 2 Cloud SQL instances in the us-central1 region with HA enabled, and create read replicas in us-east1 and us-west1.

Deploy 4 Cloud SQL instances in the us-central1 region with HA enabled, and create read replicas in us-central1, us-east1, and us-west1.

We only need options with HA enabled and 4 databases with 3 read replicas (each?) seems overkill to me.

👍 4pk3492022/12/25A is correct. We only have 8000 tables. More than 1 HA env is only required beyond 50000 tables If you have 50,000 or more database tables on a single instance, it could result in the instance becoming unresponsive or unable to perform maintenance operations, and the instance is not covered by the SLA.
