Topic 1 Question 529
2 つ選択An events company runs a ticketing platform on AWS. The company’s customers configure and schedule their events on the platform. The events result in large increases of traffic to the platform. The company knows the date and time of each customer’s events.
The company runs the platform on an Amazon Elastic Container Service (Amazon ECS) cluster. The ECS cluster consists of Amazon EC2 On-Demand Instances that are in an Auto Scaling group. The Auto Scaling group uses a predictive scaling policy.
The ECS cluster makes frequent requests to an Amazon S3 bucket to download ticket assets. The ECS cluster and the S3 bucket are in the same AWS Region and the same AWS account. Traffic between the ECS cluster and the S3 bucket flows across a NAT gateway.
The company needs to optimize the cost of the platform without decreasing the platform's availability.
Which combination of steps will meet these requirements?
Create a gateway VPC endpoint for the S3 bucket.
Add another ECS capacity provider that uses an Auto Scaling group of Spot Instances. Configure the new capacity provider strategy to have the same weight as the existing capacity provider strategy.
Create On-Demand Capacity Reservations for the applicable instance type for the time period of the scheduled scaling policies.
Enable S3 Transfer Acceleration on the S3 bucket.
Replace the predictive scaling policy with scheduled scaling policies for the scheduled events.

- 正解だと思う選択肢: AE
Options A and E will meet the requirements most cost-effectively by leveraging the predictability of the workload of known customer events to optimize scaling operations and reducing data transfer costs
👍 5wbedair2024/06/30 If you made it this far you will pass.. Good luck everyone! This is a great service.
👍 40b432912024/11/24A For S3 communication in the same region, the communication fee is waived by using the gateway VPC endpoint. B Availability is reduced when spot instances are used. C Using on-demand capacity reservation increases costs. D Using S3 Transfer Acceleration increases costs. E Scheduled scaling policies allow resources to be used according to events.
The answers are A and E.
