Exam AWS Certified Solutions Architect - Professional SAP-C02 topic 1 question 529 discussion

Exam question from Amazon's AWS Certified Solutions Architect - Professional SAP-C02
Question #: 529
Topic #: 1
[All AWS Certified Solutions Architect - Professional SAP-C02 Questions]

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? (Choose two.)

  • A. Create a gateway VPC endpoint for the S3 bucket.
  • B. 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.
  • C. Create On-Demand Capacity Reservations for the applicable instance type for the time period of the scheduled scaling policies.
  • D. Enable S3 Transfer Acceleration on the S3 bucket.
  • E. Replace the predictive scaling policy with scheduled scaling policies for the scheduled events.

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

A,E By creating a gateway VPC endpoint for the S3 bucket (option A), you can reduce latency and improve performance by routing traffic directly through Amazon's network, rather than relying on the NAT gateway. And by replacing the predictive scaling policy with scheduled scaling policies for the scheduled events (option E), you can avoid scaling instances during low-traffic periods, which would reduce costs and prevent unnecessary charges.

Selected Answer: AB
A. Create a gateway VPC endpoint for the S3 bucket: This will allow the ECS cluster to access the S3 bucket directly without the need for traffic to flow through the NAT gateway, reducing costs associated with NAT data transfer. B. Add another ECS capacity provider that uses an Auto Scaling group of Spot Instances: By introducing Spot Instances with the same weight as On-Demand Instances, the company can take advantage of the cost savings from Spot Instances while maintaining the ability to scale with On-Demand Instances when needed. These steps will reduce network traffic costs and take advantage of lower-cost compute options without compromising platform availability.

A 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.
