The answer is the failover routing policy, which is the correct choice because it enables active-passive DNS failover by allowing you to designate a primary resource, such as an Application Load Balancer, and a secondary resource, like a static error page hosted on an S3 bucket, so that traffic automatically shifts to the secondary when health checks detect the primary has failed. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this question tests your understanding of Route 53 routing policies in high-availability architectures, often appearing in scenarios where you must distinguish failover from weighted, latency, or geolocation routing—a common trap is confusing failover with weighted routing, but remember that failover is strictly for primary-secondary redundancy, not traffic distribution. A useful memory tip is to think of failover as a "standby switch": if the main path breaks, the backup takes over without manual intervention.
SOA-C02 Networking and Content Delivery Practice Question
This SOA-C02 practice question tests your understanding of networking and content delivery. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. 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 company is using Amazon Route 53 as its DNS service. The company has a web application running on an Auto Scaling group of EC2 instances behind an Application Load Balancer (ALB). The company wants to ensure that if the ALB fails, traffic is automatically redirected to a static error page hosted on an Amazon S3 bucket. Which Route 53 routing policy should be used to achieve this?
Why wrong: Geolocation routing policy routes traffic based on the geographic location of the user, not for failover.
B
Failover routing policy
Failover routing policy enables active-passive failover, where the primary resource is used and traffic is redirected to a secondary resource (S3 bucket) if the primary fails.
C
Latency routing policy
Why wrong: Latency routing policy routes traffic to the region with the lowest latency, not for failover to a static site.
D
Weighted routing policy
Why wrong: Weighted routing distributes traffic among multiple resources based on assigned weights, not for active-passive failover.
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
Failover routing policy
Option B is correct because a failover routing policy allows you to configure active-passive failover with primary and secondary records. Option A is wrong because weighted routing distributes traffic based on weights. Option C is wrong because latency routing routes to the region with the lowest latency. Option D is wrong because geolocation routing routes based on the user's geographic location.
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
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.

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.
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 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.
