SAA-C03 Question 173
Single answerA company has deployed a web application across multiple AWS Regions to serve users with low latency. They need to configure a DNS routing policy that directs users to the nearest AWS Region based on their geographic location. Which Amazon Route 53 routing policy should they choose?
- A
Simple routing policy
- B
Geolocation routing policy
- C
Latency routing policy
- D
Weighted routing policy
Show answer and explanation
Correct answer: B
Explanation
The Geolocation routing policy in Amazon Route 53 is specifically designed to route traffic based on the geographic location of the user. In this scenario, the company needs to direct users to the nearest AWS Region based on their location, making the Geolocation routing policy the correct answer. Other routing policies like Simple, Latency, and Weighted do not fulfill this requirement.
- A. Incorrect.
The Simple routing policy is used when you want to route traffic to a single resource without any specific logic. It does not consider the user's geographic location.
- B. Correct.
The Geolocation routing policy allows Route 53 to direct traffic based on the user's geographic location, which is exactly what the requirement specifies.
- C. Incorrect.
The Latency routing policy is used to route traffic to the endpoint with the lowest network latency for the user. While this is related to performance, it does not specifically focus on geographic location.
- D. Incorrect.
The Weighted routing policy is used when you want to distribute traffic across multiple resources based on pre-defined weights. It does not take the user's geographic location into account.
