Full question →easymultiple choiceObjective-mapped
A production Amazon RDS database has automated backups enabled. At 10:45 UTC, an issue is discovered. The team needs to restore the database to its state as of 10:30 UTC. Which capability should they use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Point-in-time restore (PITR) using automated backups to a specific timestamp.
PITR restores an RDS DB instance to a chosen moment within the retention period for automated backups, allowing the team to roll back to 10:30 UTC.
B
Distractor review
Perform a Multi-AZ manual failover of the standby to recover to the earlier timestamp.
Failover affects database availability by promoting a standby; it does not revert the database contents to an earlier point in time. The data state continues from the latest replicated state.
C
Distractor review
Promote a cross-region replication target to replace the current database with the last-known good copy.
Cross-region replication supports disaster recovery. Unless the replicated copy is guaranteed to represent exactly 10:30 UTC (which is not the default PITR requirement), it does not provide a precise point-in-time rollback.
D
Distractor review
Switch to a read replica to access an older view of data without restoring.
Read replicas are primarily for scaling reads and offloading query load. They do not perform a point-in-time restore or rollback of the primary to a specific timestamp.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Point-in-time restore (PITR) using automated backups to a specific timestamp. — Use point-in-time restore (PITR). With automated backups enabled, AWS retains enough recovery information to restore an RDS DB instance to a specified timestamp within the automated backup retention window. That enables rolling the database back to 10:30 UTC after discovering the issue at 10:45 UTC. Multi-AZ failover, replication promotion, and read replicas do not provide the fine-grained restore-to-timestamp behavior that PITR provides. Multi-AZ failover is for availability, not data rollback. Cross-region replication promotion is for geographic resilience and may not align to the exact requested timestamp. Read replicas do not replace the need for a restore to a chosen moment; they provide alternate endpoints for reads rather than restoring state.
