PCDE Practice Question: Manage a solution that can span multiple database technologies
A company wants to use Cloud SQL for MySQL to serve a read-heavy application. They need to ensure high availability and offload read traffic. Which TWO steps should they take? (Choose two.)
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
✓
Create a same-region read replica
To ensure high availability, create a Cloud SQL HA configuration (regional instance with standby). To offload read traffic, create read replicas. Cross-region replicas are for disaster recovery but add latency. On-demand backups are for data protection, not availability. Auto-storage increase is for storage management.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
Schedule on-demand backups daily
Why it's wrong here
Backups ensure data durability, not availability or read offloading.
- ✗
Create a cross-region read replica
Why it's wrong here
Cross-region replicas add latency and are typically for disaster recovery, not for offloading reads in the same region.
- ✓
Create a same-region read replica
Why this is correct
Same-region read replicas offload read traffic and are low-latency.
- ✗
Enable auto-storage increase
Why it's wrong here
Auto-storage increase handles storage growth, not high availability or read offloading.
- ✓
Enable high availability (HA) configuration on the primary instance
Why this is correct
HA provides a synchronous standby in the same region for failover.
