This PCDE practice question tests your understanding of plan and manage database infrastructure. 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.
A company wants to ensure point-in-time recovery for their PostgreSQL database on Cloud SQL. What must they enable?
Query insights
Why wrong: Query insights is a performance monitoring feature, not related to backup or recovery.
Automatic backups
Automatic backups enable PITR for Cloud SQL PostgreSQL instances.
Write-ahead logging (WAL) archiving
Why wrong: Cloud SQL for PostgreSQL automatically manages WAL; no separate archiving setting is needed.
Binary logging
Why wrong: Binary logging is used for MySQL PITR, not PostgreSQL.
Answer choices
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
Automatic backups
Automatic backups in Cloud SQL enable point-in-time recovery (PITR) by maintaining transaction logs that allow you to restore the database to any specific time within the backup retention period. Without automatic backups enabled, Cloud SQL only supports restoring from a full backup snapshot, which does not provide the granularity needed for PITR.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
For each option: why learners choose it and why it is or isn't the right answer here.
Query insights
Why it's wrong here
Query insights is a performance monitoring feature, not related to backup or recovery.
Automatic backups
Why this is correct
Automatic backups enable PITR for Cloud SQL PostgreSQL instances.
Related concept
Read the scenario before looking for a memorised answer.
Write-ahead logging (WAL) archiving
Why it's wrong here
Cloud SQL for PostgreSQL automatically manages WAL; no separate archiving setting is needed.
Binary logging
Why it's wrong here
Binary logging is used for MySQL PITR, not PostgreSQL.
Common exam traps
Google Cloud often tests the misconception that enabling WAL archiving directly in PostgreSQL is required for PITR, but in Cloud SQL, this is abstracted away and controlled by the automatic backups setting.
Detailed technical explanation
Point-in-time recovery in Cloud SQL for PostgreSQL works by combining a full backup with continuous transaction log archiving. When automatic backups are enabled, Cloud SQL automatically manages the WAL segments and retains them for the configured retention period (default 7 days), allowing restoration to any second within that window. A common real-world scenario is recovering from an accidental data deletion: you can restore to a timestamp just before the deletion occurred, minimizing data loss.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
A cloud solutions architect for a retail company is evaluating services for a new workload. The correct answer here reflects best practice for the specific scenario described — not a general cloud recommendation. Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option. Cloud exam questions reward reading the constraint carefully: the same technology can be right or wrong depending on the use case.
