2. B. Create an AWS Lambda function that will evaluate Spend by service and nobly each team by using Amazon Simple Notification Service (Amazon SNS) notification
3. C. Invoke the Lambda function when a report is placed in the S3 bucket
4. D. Configure AWS Cost and Usage Reports to send a dairy report to an Amazon S3 bucke
5. E. Create a rule In Amazon EventBridge (Amazon CloudWatch Events) to evaluate the spend by service and notify each team by using Amazon Simple Queue Service (Amazon SOS) when the cost threshold i6 exceeded.
6. F. Use AWS Budgets :o create one cost budget and select each of the services in use Specify the budget amount defined by the finance department along with the forecasted cost threshold Enter the appropriate email recipients for the budget.

A company hosts its website in the us-east-1 Region. The company is preparing to deploy its website into the eu-central-1 Region. Website visitors who are located in Europe should access the website that is hosted in eu-central-1. All other visitors access the website that is hosted in us-east-1. The company uses Amazon Route 53 to manage the website's DNS records.
Which routing policy should a SysOps administrator apply to the Route 53 record set to meet these requirements?

1. A. Geolocation routing policy
2. B. Geoproximity routing policy
3. C. Latency routing policy
4. D. Multivalue answer routing policy

Correct Answer: A
geolocation "Geolocation routing lets you choose the resources that serve your traffic based on the geographic location of your users, meaning the location that DNS queries originate from. For example, you might want all queries from Europe to be routed to an ELB load balancer in the Frankfurt region."
Could be confused with geoproximity - "Geoproximity routing lets Amazon Route 53 route traffic to your resources based on the geographic location of your users and your resources. You can also optionally choose to route more traffic or less to a given resource by specifying a value, known as a bias. A bias expands or shrinks the size of the geographic region from which traffic is routed to a resource" the use case is not needed as per question.
