The correct first step is to enable automated backups on the source RDS for PostgreSQL DB instance, as this is the prerequisite for any cross-region snapshot copy. Without automated backups enabled, the RDS service cannot generate the automated snapshots that serve as the source for the copy operation; the cross-region copy feature specifically relies on these automated snapshots, not manual ones, to trigger replication. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this question tests your understanding of the RDS backup lifecycle and the dependency chain for disaster recovery automation—a common trap is assuming you can copy a manual snapshot directly without first enabling automated backups. The correct order of steps is: enable automated backups on the source instance, configure the cross-region snapshot copy in the RDS console or via the AWS CLI, verify that snapshots are being copied to the target region, and finally test the restoration process. A useful memory tip is "Backups first, copy second, verify third"—automated backups are the fuel for the cross-region copy engine.
SOA-C02 Reliability and Business Continuity Practice Question
This SOA-C02 practice question tests your understanding of reliability and business continuity. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 SysOps administrator needs to set up automated backups for a production Amazon RDS for PostgreSQL DB instance and copy the snapshots to another AWS Region for disaster recovery. Order the steps the administrator should take to implement this cross-region snapshot copy. (Drag each step to the correct order from first to last.) (Choose 4.)

Correct answer & explanation
✓
Enable automated backups on the source DB instance.
Option A is correct because automated backups must be enabled on the source RDS for PostgreSQL DB instance to generate the necessary snapshots for cross-region copying. Without automated backups, there are no snapshots to copy, and the cross-region copy feature relies on these automated snapshots as the source.
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 might think cross-region copy can be configured without first enabling automated backups, but automated backups are a prerequisite because the copy operation uses the automated snapshot as the source.
Detailed technical explanation
How to think about this question
Cross-region snapshot copy for RDS uses the underlying AWS Backup service or the RDS console to replicate automated snapshots to a destination region. The retention policy for cross-region snapshots is independent of the source region's retention, allowing you to keep copies for different durations. Verification involves checking the target region's RDS console or using the AWS CLI with commands like `aws rds describe-db-snapshots --region target-region` to confirm snapshots appear.

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 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.
