ANS-C01 Question 40
Select 3Your company has a multi-region application deployed in AWS, with a requirement to direct traffic to the closest region based on the end user's geographic location. The application must also failover to a backup region if the primary region becomes unhealthy. Which combination of Amazon Route 53 features should you use to meet these requirements?
- A
Geolocation routing
- B
Latency-based routing
- C
Failover routing
- D
Weighted routing
- E
Route 53 health checks
Show answer and explanation
Correct answers: A, C, E
Explanation
To meet the requirements, you need Geolocation routing to direct users to the closest region based on their geographic location, Failover routing to switch traffic to a backup region in case of failure, and Route 53 health checks to monitor the health of resources and trigger failover when needed. Latency-based routing and Weighted routing do not fulfill the specific requirements of this scenario.
- A. Correct.
Correct: Geolocation routing ensures that traffic is directed to the closest region based on the geographic location of the user.
- B. Incorrect.
Incorrect: Latency-based routing directs users to the endpoint with the lowest latency, but it does not use geographic location as the primary factor.
- C. Correct.
Correct: Failover routing allows traffic to be redirected to a backup region if the primary region becomes unhealthy, meeting the failover requirement.
- D. Incorrect.
Incorrect: Weighted routing is used to distribute traffic across multiple endpoints based on assigned weights, but it does not fulfill the geographic or failover requirements.
- E. Correct.
Correct: Route 53 health checks are necessary to monitor the health of the primary region and trigger failover routing when the primary region becomes unhealthy.
