Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
Your organization wants to use Cloud SQL for a MySQL database with automatic failover in the event of a zone outage. Which configuration should you choose?
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 regional Cloud SQL instance (high availability) with a primary and standby zone
Cloud SQL provides high availability by creating a primary instance in one zone and a standby instance (failover replica) in another zone within the same region. Automatic failover is enabled when you create a regional Cloud SQL instance. A read replica 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.
- ✗
Set up Cloud SQL with external replication to a VM in another zone
Why it's wrong here
External replication is manual and does not provide automatic failover.
- ✗
Create a Cloud SQL instance with a cross-region read replica
Why it's wrong here
Cross-region read replicas are for read scaling, not automatic failover.
- ✗
Create a single-zone Cloud SQL instance with automatic backups enabled
Why it's wrong here
Single-zone instances do not fail over automatically.
- ✓
Create a regional Cloud SQL instance (high availability) with a primary and standby zone
Why this is correct
Regional instances provide automatic failover.
