DBS-C01 Recovery Point Objective (RPO) Practice Question

This DBS-C01 practice question tests your understanding of management and operations. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. A key principle to apply: recovery Point Objective (RPO). 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 designing a disaster recovery plan for an Amazon RDS for MySQL database. The database must have a Recovery Point Objective (RPO) of less than 5 minutes and a Recovery Time Objective (RTO) of less than 1 hour. Which TWO actions should be taken? (Choose two.)

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

Deploy the database in a Multi-AZ configuration.

Option B (Multi-AZ configuration) provides automatic synchronous replication to a standby instance in a different Availability Zone. In the event of a failure, automatic failover occurs within minutes, achieving an RTO of less than 1 hour and an RPO of effectively zero. Option C (cross-region read replica with automated backups enabled) replicates data asynchronously to another AWS region, allowing promotion to a standalone database for disaster recovery. With continuous replication, the RPO can be less than 5 minutes, and promotion time is typically under 1 hour, meeting both objectives. Option A is incorrect because a single-AZ instance with automated backups requires restoring from a backup, which takes longer than 1 hour, failing the RTO requirement. Option D is incorrect because daily manual snapshots have an RPO of up to 24 hours, exceeding the 5-minute requirement. Option E is incorrect because AWS DMS is primarily a migration service and is not optimized for continuous replication for DR; it adds complexity and does not provide the same RTO/RPO guarantees as native RDS replication features.

Key principle: Recovery Point Objective (RPO)

Answer analysis

Option-by-option breakdown

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

  • Use a single-AZ instance with automated backups to S3.

    Why it's wrong here

    A single-AZ instance with automated backups to S3 requires restoring a backup, which takes longer than 1 hour, failing the RTO requirement. Also, automated backups are typically taken once per day, so RPO would exceed 5 minutes.

  • Deploy the database in a Multi-AZ configuration.

    Why this is correct

    Multi-AZ configuration provides automatic synchronous replication to a standby instance in a different Availability Zone. Automatic failover occurs within minutes, achieving RTO < 1 hour and RPO near zero.

    Related concept

    Recovery Point Objective (RPO)

  • Create a cross-region read replica with automated backups enabled.

    Why this is correct

    A cross-region read replica with automated backups enabled replicates data asynchronously to another region. Continuous replication allows RPO < 5 minutes, and promoting the replica can be done in under 1 hour, meeting both objectives.

    Related concept

    Recovery Point Objective (RPO)

  • Take daily manual snapshots and copy them to another region.

    Why it's wrong here

    Daily manual snapshots taken and copied to another region result in an RPO of up to 24 hours, which is far greater than 5 minutes. Restoring from a snapshot also takes significant time, failing RTO.

  • Use AWS DMS for continuous replication to a standby instance.

    Why it's wrong here

    AWS DMS is designed for migration and ongoing replication but is not the native DR mechanism for RDS. It adds complexity and does not guarantee the same RTO/RPO as Multi-AZ or read replicas.

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

Treat this as a scenario question. Identify the problem, the constraint, and the best action. Then compare each option against those facts.

KKey Concepts to Remember

  • Recovery Point Objective (RPO)
  • Recovery Time Objective (RTO)
  • Multi-AZ Deployment
  • Cross-Region Read Replica

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

Recovery Point Objective (RPO)

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.
