A company hosts an internal API in two AWS Regions. Traffic must automatically switch to the secondary Region when the primary Region's endpoint is unhealthy. Which two Route 53 settings are required? 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
Use a failover routing policy for the DNS record.
Failover routing is specifically designed for primary and secondary endpoints. Route 53 returns the secondary record when the primary record is considered unhealthy.
B
Best answer
Configure a health check for the primary endpoint.
Route 53 must have health information to determine whether the primary endpoint is available. The health check is what tells Route 53 to stop returning the primary record and serve the secondary one instead.
C
Distractor review
Use geolocation routing so users are always sent to the closest Region.
Geolocation routing chooses answers by the user's location, not by endpoint health. It does not provide automatic primary-to-secondary failover based on an outage.
D
Distractor review
Use a private hosted zone to expose the API to the internet.
Private hosted zones are only resolvable from associated VPCs and are not the right mechanism for public DNS failover between Regions.
E
Distractor review
Set the TTL to zero and skip health checks to make failover faster.
A lower TTL can reduce client-side caching time, but it does not detect failures or direct traffic to a backup Region by itself. Without health checks, Route 53 has no signal that the primary is unhealthy.
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: Use a failover routing policy for the DNS record. — DNS-based regional failover in Route 53 requires two parts: a failover routing policy and a health check on the primary endpoint. The routing policy defines the primary and secondary records, and the health check determines when the primary should be withdrawn so Route 53 can answer with the secondary endpoint. Geolocation routing selects answers by location, not by health status. Private hosted zones are for internal DNS resolution inside VPCs, not public failover. A low TTL can help clients refresh DNS sooner, but it does not replace health checks or failover routing.
