Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
Your organization runs a production Cloud SQL for PostgreSQL instance. You need to ensure that if the primary zone fails, the database automatically fails over to a standby with no data loss. Which configuration should you 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
✓
Deploy a regional Cloud SQL instance with high availability
Cloud SQL HA with regional instances uses synchronous replication to a standby in a different zone, ensuring zero data loss on automatic failover. Cross-region replication is for disaster recovery, not automatic failover. Point-in-time recovery is for restoration to a specific time, not failover. Read replicas are for read scaling, not 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.
- ✗
Enable point-in-time recovery (PITR)
Why it's wrong here
PITR enables recovery to a specific time, not automatic failover.
- ✗
Configure a cross-region replica
Why it's wrong here
Cross-region replicas are for disaster recovery, not automatic failover within the same region.
- ✓
Deploy a regional Cloud SQL instance with high availability
Why this is correct
Regional HA instances automatically fail over to a standby in another zone with synchronous replication, ensuring no data loss.
- ✗
Create a read replica and promote it on failure
Why it's wrong here
Read replicas are asynchronous and promoting may cause data loss; not automatic.
