Routing Policies for Global Performance

Correct Answer - B.

Route 53 latency routing policy can be used to provide the least latency when resources are deployed in multiple regions.

This policy routes users' requests to the nearest resource based upon latency.

Option A is incorrect as Route 53 weighted routing policy is used to distribute requests between multiple resources based upon weight of each.

Option C is incorrect as Route 53 Geoproximity routing policy can be used to route traffic based upon the location of the resource.

Option D is incorrect as Route 53 Geolocation routing policy can be used to route traffic based upon user location.

To provide the best performance to global users accessing a static website deployed on Amazon S3 buckets at multiple regions, the ideal routing policy to use would be Route 53 latency routing policy.

The Route 53 latency routing policy directs traffic to the AWS region that provides the lowest network latency for the end user. This means that when a user requests a website, Route 53 checks the latency between the user and each of the available AWS regions that host the website and then directs the user to the region with the lowest latency.

This policy is particularly useful for static websites that are hosted on Amazon S3 buckets at multiple regions because it ensures that users can access the website with the lowest possible latency. This helps to reduce the loading time of the website and provides a better user experience.

The other routing policies listed are not as ideal for this use case:

• The Route 53 weighted routing policy is used when traffic needs to be distributed across multiple resources in proportions that you specify. This is not optimal for a static website hosted on Amazon S3 buckets at multiple regions.
• The Route 53 Geoproximity routing policy is used when you want to route traffic based on the geographic location of the user making the request. This policy is useful when you have resources that are closer to specific geographic locations, but it may not be the best choice for a static website hosted on Amazon S3 buckets at multiple regions.
• The Route 53 Geolocation routing policy is used to route traffic based on the geographic location of the user making the request. This policy is similar to the geoproximity routing policy, but it provides more granularity in terms of the geographic locations that can be used to route traffic. However, it may not be the best choice for a static website hosted on Amazon S3 buckets at multiple regions.
