- A
Configure automated backups with 7-day retention.
Why wrong: Backups provide point-in-time recovery, not HA/DR failover.
- B
Enable High Availability (HA) configuration on the primary instance.
HA provides zonal failover with synchronous replication to another zone.
- C
Create a cross-region read replica for failover.
Cross-region replica can be promoted in case of regional outage.
- D
Use Cloud SQL Proxy for secure connections.
Why wrong: Proxy is for connectivity, not HA/DR.
- E
Enable binary logging for point-in-time recovery.
Why wrong: PITR helps with data recovery, not HA/DR.

PCDOE Manage Database Solutions Practice Question
This PCDOE practice question tests your understanding of manage database solutions. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company is migrating on-premises MySQL databases to Cloud SQL. They need to ensure high availability and disaster recovery with minimal data loss. Which TWO configurations should they implement?
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 High Availability (HA) configuration on the primary instance.
Option B is correct because enabling High Availability (HA) configuration on a Cloud SQL primary instance creates a synchronous standby in a different zone within the same region, providing automatic failover with minimal data loss (typically under one second). This directly addresses the need for high availability with minimal data loss during a zonal outage.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
Cisco often tests the distinction between synchronous replication (HA within region) and asynchronous replication (cross-region read replicas), where candidates mistakenly think a cross-region read replica alone provides automatic failover with minimal data loss, but it actually requires manual promotion and has higher RPO.
Detailed technical explanation
How to think about this question
Cloud SQL HA uses synchronous replication to a standby instance in a different zone, ensuring that transactions are committed on both instances before acknowledging the client; this guarantees near-zero data loss (RPO < 1 second) during a zonal failover. Cross-region read replicas use asynchronous replication, which can introduce seconds to minutes of data loss (RPO > 1 second) but provide DR across regions; they can be promoted to standalone instances for failover, but the promotion is manual and not automatic.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
An e-commerce site experiences heavy traffic on Black Friday and near-zero traffic during off-peak weeks. Rather than provisioning permanent large VMs, the team uses auto-scaling groups that add capacity automatically under load and reduce it overnight. Questions like this test whether you understand elasticity, availability zones, and cloud compute scaling patterns.
