Google PCA Practice Question: Managing Implementation and Ensuring Solution and Operations Reliability
You need to enable high availability for a new Cloud SQL for MySQL instance. Which TWO configurations must you set? (Choose 2)
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
✓
Enable automatic backups
To enable HA for Cloud SQL, you must create a regional instance (which automatically provisions a standby in a different zone) and ensure automatic backups are enabled (required for failover and PITR). Read replicas are for read scaling, not HA. Binary logging is for replication and PITR, but it is enabled by default for HA instances. Database flags are not required for HA.
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 the 'cloudsql.mysql' database flag for HA
Why it's wrong here
No such flag exists.
- ✗
Create a read replica in a different region
Why it's wrong here
Read replicas do not provide automatic failover.
- ✓
Enable automatic backups
Why this is correct
Automatic backups are required for HA failover and point-in-time recovery.
- ✓
Select the 'High availability (regional)' option when creating the instance
Why this is correct
This creates a primary and standby in different zones.
- ✗
Enable binary logging
Why it's wrong here
Binary logging is enabled by default for HA instances; not a separate configuration.
