Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
A company has a Cloud SQL for PostgreSQL instance in a single zone. To achieve high availability, they want to ensure automatic failover with zero data loss and minimal downtime. Which configuration should they use?
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Configure a Cloud SQL regional instance with a failover replica in a different zone
Cloud SQL HA requires a regional instance with a failover replica in a different zone within the same region. This provides automatic failover and synchronous replication to ensure zero data loss. Read replicas are for read scaling, not automatic failover. Cross-region replication does not provide automatic failover.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Deploy a read replica in the same zone and enable automatic failover
Why it's wrong here
Read replicas do not support automatic failover; they are for offloading reads.
- ✗
Enable automatic backups and point-in-time recovery
Why it's wrong here
Backups and PITR provide data recovery but not high availability with automatic failover.
- ✗
Add a cross-region read replica and configure failover manually
Why it's wrong here
Cross-region replicas are for disaster recovery, not automatic failover. Manual failover requires intervention.
- ✓
Configure a Cloud SQL regional instance with a failover replica in a different zone
Why this is correct
This is the correct HA configuration for Cloud SQL, providing automatic failover and synchronous replication.
