The correct answer is the failover routing policy. This policy is designed for an active-passive setup, where all traffic is routed to a primary resource—such as an Elastic Load Balancer in your primary AWS region—until a Route 53 health check marks it as unhealthy, at which point traffic is automatically diverted to a secondary disaster recovery resource in another region. On the AWS Certified SysOps Administrator Associate SOA-C02 exam, this question tests your understanding of how to implement disaster recovery routing with Route 53 failover policy, often appearing in scenarios that require multi-region resilience. A common trap is confusing failover with weighted routing; remember that failover is strictly binary (primary or secondary), not a distribution of load. For a quick memory tip, think of it as a "flip-the-switch" mechanism: healthy primary gets 100% traffic, unhealthy primary flips all traffic to the secondary.
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 SysOps administrator needs to route traffic to multiple AWS regions for disaster recovery using Amazon Route 53. The primary region should receive all traffic unless it becomes unhealthy. Which routing policy should be used?

Correct answer & explanation
✓
Failover routing policy
Failover routing policy is correct because it allows you to configure an active-passive setup where all traffic is directed to a primary resource (e.g., an Elastic Load Balancer in the primary region) unless Route 53 health checks determine that the primary is unhealthy. When the primary fails, Route 53 automatically routes traffic to the secondary (disaster recovery) resource in another region. This directly meets the requirement of sending all traffic to the primary region unless it becomes unhealthy.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
✓
Failover routing policy
Why this is correct
Failover routing sends traffic to a primary resource and fails over to a secondary when the primary is unhealthy.

Related concept
Read the scenario before looking for a memorised answer.
✗
Geolocation routing policy
Why it's wrong here
Geolocation routing routes based on geographic location of the user, not for failover.
✗
Latency routing policy
Why it's wrong here
Latency routing directs traffic to the region with the lowest latency, not failover.
✗
Weighted routing policy
Why it's wrong here
Weighted routing is used for distributing traffic across multiple resources by weight, not for failover.
Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates often confuse failover routing with weighted or latency routing, thinking they can achieve disaster recovery by distributing traffic, but only failover routing provides the required active-passive health-based failover behavior.
Detailed technical explanation
How to think about this question
Route 53 failover routing relies on health checks that can monitor endpoints via HTTP, HTTPS, TCP, or even CloudWatch alarms. When a health check fails, Route 53 automatically updates DNS responses to return the secondary record's IP, with a TTL that controls failover speed. In a real-world scenario, you must ensure the secondary region is scaled and ready to handle traffic, as DNS failover is not instantaneous and depends on client DNS caching.

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.
