A company stores customer data in a multitenant Amazon S3 bucket. Each customer's data is stored in a prefix that is unique to the customer. The company needs to migrate data for specific customers to a new. dedicated S3 bucket that is in the same AWS Region as the source bucket.

Explanation:

The solution that meets the requirements of high availability, performance, security, and static IP addresses is to use Amazon CloudFront, Application Load Balancers (ALBs), Amazon Route 53, and AWS WAF. This solution allows the company to distribute its HTTP-based application globally using CloudFront, which is a content delivery network (CDN) service that caches content at edge locations and provides static IP addresses for each edge location. The company can also use Route 53 latency-based routing to route requests to the closest ALB in each Region, which balances the load across the EC2 instances. The company can also deploy AWS WAF on the CloudFront distribution to protect the application against common web exploits by creating rules that allow, block, or count web requests based on conditions that are defined. The other solutions do not meet all the requirements because they either use Network Load Balancers (NLBs), which do not support HTTP-based applications, or they do not use CloudFront, which provides better performance and security than AWS Global Accelerator.Reference:=
