AWS Certified SysOps Administrator – Associate — Question 332
A company's social media application has strict data residency requirements. The company wants to use Amazon Route 53 to provide the application with DNS services.
A SysOps administrator must implement a solution that routes requests to a defined list of AWS Regions. The routing must be based on the user's location.
Which solution will meet these requirements?
Answer options
- A. Configure a Route 53 latency routing policy.
- B. Configure a Route 53 multivalue answer routing policy.
- C. Configure a Route 53 geolocation routing policy.
- D. Configure a Route 53 IP-based routing policy.
Correct answer: C
Explanation
A Route 53 geolocation routing policy allows traffic to be directed to specific resources based on the geographic location of the users, which directly addresses the data residency and location-based routing requirements. Latency routing directs traffic based on the lowest network latency rather than strict geographic boundaries, while multivalue answer routing is used for distributing DNS responses across multiple IP addresses for basic load balancing. IP-based routing maps user IP addresses to specific endpoints but does not natively handle geographic location mapping as precisely or easily for data residency compliance as geolocation routing.
