- A
Enable 'auto-storage increase' in the instance settings.
Correct. This setting automatically increases storage.
- B
Use Active Assist recommendations to manually resize.
Why wrong: Active Assist provides recommendations, but does not automatically increase storage.
- C
Set up a Cloud Monitoring alert to manually increase storage when usage exceeds 80%.
Why wrong: Manual intervention is not automatic.
- D
Configure a Cloud Function to resize the disk via API when threshold is reached.
Why wrong: Possible but not the standard built-in feature; the auto-storage increase is simpler.

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 using Cloud SQL and wants to automatically increase storage when disk usage reaches a threshold. What should they configure?
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 'auto-storage increase' in the instance settings.
Cloud SQL provides a built-in 'auto-storage increase' setting that, when enabled, automatically increases the instance's storage capacity when disk usage reaches a predefined threshold (typically 90% or when free space drops below a certain amount). This eliminates the need for manual intervention or custom automation, ensuring high availability and preventing out-of-disk errors.
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
The trap here is that candidates may over-engineer a solution (e.g., Cloud Functions or Monitoring alerts) when a simple, built-in configuration option exists, or they may confuse Active Assist recommendations with automated actions.
Detailed technical explanation
How to think about this question
When 'auto-storage increase' is enabled, Cloud SQL monitors the disk usage and automatically increases the storage by a predefined increment (e.g., 10 GB or 20% of current size) when free space drops below the threshold, with a maximum storage limit set by the user. This process is transparent and does not cause downtime, but note that storage increases are irreversible—you cannot decrease storage after it has been increased. In a real-world scenario, if you have a database with unpredictable write spikes (e.g., during Black Friday sales), enabling this feature prevents the instance from going read-only due to full disk, which would otherwise require manual intervention.
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
A media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
