- A
Failover routing
Why wrong: Failover routing directs all traffic to the primary endpoint and only routes to the secondary when the primary is unhealthy. It does not split traffic proportionally.
- B
Geolocation routing
Why wrong: Geolocation routing directs traffic to specific endpoints based on the user's geographic location. It does not split traffic by percentage between two versions.
- C
Weighted routing
Weighted routing assigns relative weights to route records. A weight of 10 for the new version and 90 for the existing version routes approximately 10% of requests to the new version — ideal for gradual canary deployments.
- D
Latency routing
Why wrong: Latency routing directs users to the AWS region with the lowest latency. It does not split traffic proportionally between two versions of an application.
Quick Answer
The answer is the weighted routing policy. This is correct because it allows you to assign a relative weight to each resource, enabling precise traffic distribution—such as sending 10% of user traffic to a new application version and 90% to the existing version—and then gradually adjust those weights as confidence grows, making it ideal for controlled canary deployments. On the AWS Certified Cloud Practitioner CLF-C02 exam, this question tests your understanding of how Route 53 routing policies map to real-world scenarios, often appearing alongside simple routing, failover, or latency-based policies as a distractor. A common trap is confusing weighted routing with simple routing, which only sends traffic to a single endpoint, or with failover routing, which is for disaster recovery. To remember it, think of a scale: you assign “weights” like percentages on a balance, and you can tip the scale slowly as you gain confidence in the new version.
CLF-C02 Cloud Technology and Services Practice Question
This CLF-C02 practice question tests your understanding of cloud technology and services. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. 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 wants to test a new version of their application by sending 10% of user traffic to the new version and 90% to the existing version, gradually increasing traffic to the new version as confidence grows. Which Amazon Route 53 routing policy supports this?

Correct answer & explanation
Weighted routing
Weighted routing (C) is correct because it allows you to assign a percentage of traffic to each resource, such as 10% to the new version and 90% to the existing version. As confidence grows, you can adjust the weights to gradually shift more traffic to the new version. This policy is specifically designed for load balancing between multiple endpoints in a controlled, proportional manner.
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
The trap here is that candidates often confuse weighted routing with latency routing, thinking that latency-based routing can also distribute traffic proportionally, but latency routing only optimizes for response time and cannot enforce a fixed percentage split.
Detailed technical explanation
How to think about this question
Weighted routing in Route 53 uses a weight value (0–255) assigned to each record; the proportion of traffic to each endpoint is calculated as (weight of that record) / (sum of all weights). For example, weights of 10 and 90 yield a 10% and 90% split. A subtle behavior is that if you set a weight to 0, traffic stops going to that endpoint, which is useful for temporarily disabling a version without deleting the record. In real-world scenarios, this is commonly used for canary deployments or A/B testing where traffic is gradually shifted based on monitoring metrics.
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.
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.
