Cost effective way to save infrastructure

[Samli]

A company is updating an application that customers use to make online orders. The number

of attacks on the application by bad actors has increased recently.

The company will host the updated application on an Amazon Elastic Container Service (Amazon ECS)

cluster. The company will use Amazon DynamoDB to store application dat a. A public Application

Load Balancer (ALB) will provide end users with access to the application. The company must prevent

prevent attacks and ensure business continuity with minimal service interruptions during an ongoing

attack.

Which combination of steps will meet these requirements MOST cost-effectively? (Select TWO.)

A. Create an Amazon CloudFront distribution with the ALB as the origin. Add a custom header and

random value on the CloudFront domain. Configure the ALB to conditionally forward traffic if the

header and value match.

B. Deploy the application in two AWS Regions. Configure Amazon Route 53 to route to both Regions

with equal weight.

C. Configure auto scaling for Amazon ECS tasks. Create a DynamoDB Accelerator (DAX) cluster.

D. Configure Amazon ElastiCache to reduce overhead on DynamoDB.

E. Deploy an AWS WAF web ACL that includes an appropriate rule group. Associate the web ACL with the Amazon CloudFront distribution.

Since this is asking for cost efecting way, which one is answer?
AE or AC
