DBS-C01 Workload-Specific Database Design Practice Question

A company runs a critical PostgreSQL database on Amazon RDS and needs to implement point-in-time recovery (PITR) with a recovery window of the last 35 days. Currently, automated backups are set to retain for 35 days. The database size is 500 GB. What additional configuration is required?

⚠ Common exam trap

Many exam-takers think PITR requires additional components like manual snapshots or replication slots, but RDS automated backups already include the necessary transaction logs for PITR when the retention period is set appropriately.

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

No additional configuration is required; automated backups enable PITR

Amazon RDS for PostgreSQL automated backups include transaction logs, which are required for point-in-time recovery. With automated backups retained for 35 days, RDS can restore the database to any second within that retention period by replaying transaction logs against a full backup. No additional configuration is needed because PITR is an inherent feature of automated backups when the retention period is set to 35 days.

Answer analysis

Option-by-option breakdown

For each option: why learners choose it and why it is or isn't the right answer here.

  • No additional configuration is required; automated backups enable PITR

    Why this is correct

    RDS automatically supports PITR with automated backups.

  • Enable manual snapshots every hour

    Why it's wrong here

    Manual snapshots are not needed for PITR.

  • Set up a replication slot and stream transaction logs to S3

    Why it's wrong here

    Not needed; RDS handles transaction logs internally.

  • Enable Multi-AZ deployment

    Why it's wrong here

    Multi-AZ does not affect PITR.
