- A
Export the database daily using Dataflow to Cloud Storage.
Why wrong: Dataflow export is not necessary; Spanner has built-in backup and PITR.
- B
Use gcloud spanner databases import to restore from previous exports.
Why wrong: Import is for restoring from exports, but not required if you have backups and PITR.
- C
Create full database backups using gcloud spanner backups create and set retention to 7 days.
Full backups complement PITR and provide a restore baseline.
- D
Enable point-in-time recovery (PITR) with a 7-day retention period.
Spanner PITR allows restoring to any point in the last 7 days without additional cost.
- E
Use Cloud Scheduler to trigger regular full backups via gcloud commands.
Automated backups ensure you have restore points.

PCDOE Manage Database Solutions Practice Question
This PCDOE practice question tests your understanding of manage database solutions. Read the scenario carefully and evaluate each option against the stated constraints before committing to an answer. 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.
Your organisation uses Cloud Spanner for a globally distributed application. You need to set up a backup strategy that allows restoring the database to a specific point in time within the last 7 days, with minimal impact on performance. Which THREE actions should you take? (Choose THREE.)
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 full database backups using gcloud spanner backups create and set retention to 7 days.
Spanner supports database-level backups (full backup to GCS), point-in-time recovery (PITR) via the built-in feature (which uses the versioning of Spanner), and export/import for long-term retention. For point-in-time restore within 7 days, PITR is ideal. Also, taking full backups regularly ensures you have a restore point. Option A (use Cloud Scheduler to trigger backups) automates backups. Option C (enable PITR) is built-in. Option D (perform full backups using gcloud spanner backups create) creates backups. Option B is not needed if PITR is enabled. Option E is for import/export but is slower.
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
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Detailed technical explanation
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.
