SAP-C02 Exam - Question 528

Question

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.)

Examice · Accepted Answer

Creating a gateway VPC endpoint for the S3 bucket will reduce data transfer costs by eliminating the need for traffic to go through the NAT gateway, which incurs charges. Replacing the predictive scaling policy with scheduled scaling policies will ensure that scaling operations are based on the known dates and times of customer events, optimizing resource utilization and reducing costs associated with over-provisioning. Together, these steps will optimize costs without compromising 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.
