ANS-C01 Question 288
Select 2Your organization deploys a global application using multiple AWS Regions, and you want to manage traffic routing to your application based on user latency and geographical location. Which AWS service and configuration options can help you achieve this?
- A
Amazon Route 53 with a latency-based routing policy
- B
Amazon Route 53 with a geolocation routing policy
- C
Elastic Load Balancing with cross-zone load balancing enabled
- D
AWS Global Accelerator with geoproximity routing
- E
Amazon CloudFront with geo-restriction (geoblocking) enabled
- F
Amazon Route 53 with a failover routing policy
Show answer and explanation
Correct answers: A, B
Explanation
Amazon Route 53 supports both latency-based and geolocation routing policies, making it an ideal choice for managing traffic globally based on latency and user geography. Latency-based routing improves user experience by directing users to the region with the lowest latency, while geolocation routing ensures compliance or serves location-specific content. Other services like Elastic Load Balancing, AWS Global Accelerator, and Amazon CloudFront do not offer both latency and geographical traffic management capabilities.
- A. Correct.
Correct: Amazon Route 53 with a latency-based routing policy directs users to the AWS Region providing the lowest latency, which is ideal for optimizing user experience.
- B. Correct.
Correct: Amazon Route 53 with a geolocation routing policy allows traffic to be routed based on the geographical location of the user, which can help meet compliance or localization requirements.
- C. Incorrect.
Incorrect: Elastic Load Balancing with cross-zone load balancing ensures that traffic is distributed evenly among backend instances across availability zones within the same region, but it does not manage global traffic or consider latency/geography.
- D. Incorrect.
Incorrect: AWS Global Accelerator improves application performance by routing traffic to the optimal endpoint, but it does not support geolocation routing. Geoproximity routing is not a feature of AWS Global Accelerator.
- E. Incorrect.
Incorrect: Amazon CloudFront with geo-restriction (geoblocking) enables or restricts access to content based on user location but does not manage traffic routing.
- F. Incorrect.
Incorrect: Amazon Route 53 with a failover routing policy is used for high availability and disaster recovery to switch traffic between primary and secondary resources but does not manage traffic based on latency or geography.
