PCDE Practice Question: Deploy scalable and highly available databases in Google Cloud
A company uses AlloyDB for PostgreSQL for their operational database. They want to ensure automatic failover with the shortest possible RTO. 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
✓
Deploy a multi-zone AlloyDB cluster with automatic failover enabled
AlloyDB provides automatic failover with RTO under 60 seconds. Cross-zone failover in a multi-zone cluster provides the best availability within a region. Cross-region replication is not automatic and requires manual promotion. Basic instances offer no HA. Read pool failover is not automatic.
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 single-zone AlloyDB cluster with a read pool
Why it's wrong here
Single-zone clusters do not provide automatic failover; a zone failure would cause downtime.
- ✗
Configure a cross-region read replica and set up automated promotion scripts
Why it's wrong here
Cross-region replicas require manual promotion; they do not provide automatic failover.
- ✗
Use an AlloyDB basic (single-node) instance
Why it's wrong here
Basic instances have no HA; failover is not automatic.
- ✓
Deploy a multi-zone AlloyDB cluster with automatic failover enabled
Why this is correct
AlloyDB's multi-zone cluster provides automatic failover to a standby in another zone, with RTO typically under 30 seconds.
