A web application uses Amazon RDS for MySQL in a Multi-AZ deployment. During a planned maintenance event, the team wants to understand which two statements about failover are accurate so they can design connection handling correctly. Which two statements are accurate? Select two.
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
RDS automatically promotes the synchronous standby in the same Region if the primary instance becomes unavailable.
This is the core Multi-AZ availability behavior. AWS manages the standby and promotes it automatically during failure or maintenance events, keeping the database available within the Region with minimal administrative effort.
B
Distractor review
The standby instance can serve production read traffic to improve read scaling in standard RDS Multi-AZ.
In standard RDS Multi-AZ, the standby exists for high availability and failover, not for serving application reads. Read scaling requires a different pattern, such as read replicas or Aurora reader endpoints.
C
Distractor review
The application must permanently change its connection string to a new host after failover completes.
RDS uses the same database endpoint for the Multi-AZ deployment, so applications do not need to hardcode a new host after failover. The endpoint name stays stable, which reduces recovery complexity.
D
Best answer
Existing database connections are interrupted and the application should retry by reconnecting to the same database endpoint.
During failover, active sessions are dropped because the database role changes. A resilient application must handle transient errors and reconnect to the same endpoint so DNS can resolve to the new primary.
E
Distractor review
Multi-AZ provides protection against a full Region outage without any additional design changes.
Multi-AZ improves availability within a single Region, but it is not a regional disaster recovery solution. A full Region outage requires a multi-Region strategy such as pilot light, warm standby, or active-active.
Common exam trap
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.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

FAQ
Questions learners often ask
What does this SAA-C03 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: RDS automatically promotes the synchronous standby in the same Region if the primary instance becomes unavailable. — Multi-AZ RDS is a high-availability feature within one Region. AWS automatically promotes the standby when the primary fails or is replaced during maintenance, and the application should reconnect after a brief interruption. The important design point is that the endpoint remains stable, so clients retry the same DNS name rather than switching to a different hostname manually. Why others are wrong: The standby in standard RDS Multi-AZ is not used for normal reads, so it does not increase read throughput. Applications also do not need a permanent connection string change because the endpoint stays the same. Finally, Multi-AZ is not a full regional disaster recovery solution; it protects against instance or AZ problems, not a Region-wide outage.
