SAP-C02 Question 197
Single answerA company is hosting a multi-region application that serves users globally. They want to ensure users are routed to the nearest application endpoint to minimize latency. Additionally, in the event of an endpoint failure, traffic should automatically failover to the next closest endpoint. Which Route 53 routing policy should be used to achieve this?
- A
Simple Routing Policy
- B
Geolocation Routing Policy
- C
Latency Routing Policy with Health Checks
- D
Failover Routing Policy
Show answer and explanation
Correct answer: C
Explanation
To minimize latency and ensure high availability, the Latency Routing Policy with Health Checks is the ideal choice. This policy directs users to the endpoint with the lowest latency and automatically fails over if an endpoint is deemed unhealthy. Other policies like Simple, Geolocation, and Failover do not meet both requirements of minimizing latency and supporting failover.
- A. Incorrect.
Simple Routing Policy does not provide any mechanism for routing users to the nearest endpoint or failover. It simply routes traffic based on a single record.
- B. Incorrect.
Geolocation Routing Policy routes users based on their geographic location but does not automatically failover to other endpoints in case of failure.
- C. Correct.
Latency Routing Policy with Health Checks is the correct option as it routes users to the nearest endpoint based on latency and supports failover to other healthy endpoints if the primary one becomes unavailable.
- D. Incorrect.
Failover Routing Policy supports primary and secondary failover but does not consider latency for routing users to the nearest endpoint.
