ANS-C01 Question 287
Select 2An organization wants to serve users globally from multiple AWS Regions using Amazon Route 53. They need to direct traffic based on the lowest latency for users but also want to ensure that certain regions serve a larger proportion of traffic for testing purposes. Which combination of Route 53 routing policies should they use to meet this requirement?
- A
Latency-based routing
- B
Geolocation routing
- C
Weighted routing
- D
Failover routing
- E
Multivalue answer routing
Show answer and explanation
Correct answers: A, C
Explanation
To meet the requirements, the organization should combine Latency-based routing and Weighted routing. Latency-based routing ensures that users are directed to the region with the lowest latency, improving performance. Weighted routing allows the organization to control the proportion of traffic directed to specific regions for testing purposes. Geolocation, failover, and multivalue answer routing do not address these specific requirements effectively.
- A. Correct.
Latency-based routing allows Route 53 to route traffic to the region with the lowest latency from the user's location, fulfilling the requirement to optimize performance.
- B. Incorrect.
Geolocation routing is used to route traffic based on the physical location of the users, which does not align with the requirement to optimize based on latency or proportionally distribute traffic for testing purposes.
- C. Correct.
Weighted routing enables Route 53 to distribute traffic across multiple resources with specific proportions, which meets the requirement to send a larger proportion of traffic to certain regions for testing.
- D. Incorrect.
Failover routing is used to route traffic to a secondary resource when the primary resource is unhealthy. This does not align with the requirement to optimize traffic based on latency or specific proportions.
- E. Incorrect.
Multivalue answer routing is used to return multiple IP addresses for DNS queries, helping with simple load balancing and health checking, but it does not meet the requirement to optimize based on latency or distribute traffic proportionally.
