Amazon Route 53 uses geolocation routing to route traffic based on the geographic location of the users, meaning the location from which DNS queries originate1. When a user located in London visits Thomas’s domain, Amazon Route 53 will likely route the user request to the location that provides the best latency or is geographically closest among the available options.

Geolocation Routing: Route 53 will identify the geographic location of the user in London and route the request to the nearest or most appropriate endpoint.

Routing Decision: Given the locations mentioned (Florida, Paris, and Singapore), Paris is geographically closest to London compared to Florida and Singapore.

Latency Consideration: If latency-based routing is also configured, Route 53 will route the request to the region that provides the best latency, which is likely to be Paris for a user in London2.

Final Routing: Therefore, the user request from London will be routed to the machines in Paris, ensuring a faster and more efficient response.

References:Amazon Route 53’s routing policies are designed to optimize the user experience by directing traffic based on various factors such as geographic location, latency, and health checks12. The geolocation routing policy, in particular, helps in serving traffic from the nearest regional endpoint, which in this case would be Paris for a user located in London1.

Amazon CloudTrail: AWS CloudTrail is a service that enables governance, compliance, operational auditing, and risk auditing of your AWS account1.

API Call History: It provides an event history of your AWS account activity, including actions taken through the AWS Management Console, AWS SDKs, command line tools, and other AWS services1.

Security Analysis: The AWS API call history produced by CloudTrail enables security analysis, resource change tracking, and compliance auditing1.

Operational Auditing: CloudTrail continuously monitors and logs account activity across all AWS services, including actions taken by a user, role, or AWS service1.

Compliance Auditing: CloudTrail logs provide detailed records of all API calls, which can be used to audit compliance with regulatory standards like HIPAA and PCI2.

Bucket Naming Guidelines: Google Cloud Storage requires that bucket names must be unique, contain only lowercase letters, numbers, dashes (-), underscores (_), and dots (.), and start and end with a number or letter1.

Valid Bucket Name: Based on these guidelines, the valid bucket name from the options provided is ‘company-storage-data’ because it only contains lowercase letters, numbers, and dashes1.

Invalid Bucket Names: The other options are invalid because:

Option B and C contain uppercase letters, which are not allowed1.

Option D contains spaces, which are also not allowed1.
