ANS-C01 Question 290
Select 2You manage a global application hosted in multiple AWS Regions. To provide an optimal user experience, you must ensure traffic is routed to the region closest to the user, while also having the ability to shift traffic dynamically between regions during maintenance or outages. Which combination of traffic management methods in Amazon Route 53 would best meet these requirements?
- 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 of routing users to the nearest region and dynamically shifting traffic during maintenance or outages, a combination of latency-based routing and weighted routing is ideal. Latency-based routing ensures optimal performance for users by routing them to the region with the lowest latency. Weighted routing enables you to control traffic distribution between regions dynamically, which is useful during maintenance or outages. Other routing methods, like geolocation or failover, do not fully address both aspects of the requirement.
- A. Correct.
Latency-based routing ensures that users are routed to the region with the lowest latency, which helps provide the best user experience.
- B. Incorrect.
Geolocation routing routes traffic based on the geographic location of users, but it does not dynamically shift traffic between regions, making it less suitable for the requirement.
- C. Correct.
Weighted routing allows you to distribute traffic dynamically by assigning weights to different regions, enabling you to shift traffic during maintenance or outages.
- D. Incorrect.
Failover routing is used for disaster recovery scenarios, where traffic is routed to a secondary resource only when the primary fails. It does not dynamically shift traffic as described in the requirement.
- E. Incorrect.
Multivalue answer routing provides basic DNS-based load balancing by returning multiple IP addresses, but it lacks the advanced traffic management features required in this scenario.
