A company recently launched a new product that is highly available in one AWS Region The product consists of an application that runs on Amazon Elastic Container Service (Amazon ECS), a public Application Load Balancer (ALB), and an Amazon DynamoDB table. The company wants a solution that will make the application highly available across Regions.

Which combination of steps will meet these requirements? (Select THREE.)

A.

In a different Region, deploy the application to a new ECS cluster that is accessible through a new ALB.

Answers
A.

In a different Region, deploy the application to a new ECS cluster that is accessible through a new ALB.

B.

Create an Amazon Route 53 failover record.

Answers
B.

Create an Amazon Route 53 failover record.

C.

Modify the DynamoDB table to create a DynamoDB global table.

Answers
C.

Modify the DynamoDB table to create a DynamoDB global table.

D.

In the same Region, deploy the application to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster that is accessible through a new ALB.

Answers
D.

In the same Region, deploy the application to an Amazon Elastic Kubernetes Service (Amazon EKS) cluster that is accessible through a new ALB.

E.

Modify the DynamoDB table to create global secondary indexes (GSIs).

Answers
E.

Modify the DynamoDB table to create global secondary indexes (GSIs).

F.

Create an AWS PrivateLink endpoint for the application.

Answers
F.

Create an AWS PrivateLink endpoint for the application.

Suggested answer: A, B, C

Explanation:

To make the application highly available across regions:

Deploy the application in a different region using a new ECS cluster and ALB to ensure regional redundancy.

Use Route 53 failover routing to automatically direct traffic to the healthy region in case of failure.

Use DynamoDB Global Tables to ensure the database is replicated and available across multiple regions, supporting read and write operations in each region.

Option D (EKS cluster in the same region): This does not provide regional redundancy.

Option E (Global Secondary Indexes): GSIs improve query performance but do not provide multi-region availability.

Option F (PrivateLink): PrivateLink is for secure communication, not for cross-region high availability.
