A Retail Company Processes Point-Of-Sale Data on Application Servers in Its

question 703

Multiple Choice

A retail company processes point-of-sale data on application servers in its data center and writes outputs to an Amazon DynamoDB table. The data center is connected to the company's VPC with an AWS Direct Connect (DX) connection, and the application servers require a consistent network connection at speeds greater than 2 Gbps. The company decides that the DynamoDB table needs to be highly available and fault tolerant. The company policy states that the data should be available across two regions. What changes should the company make to meet these requirements?

• A) Establish a second DX connection for redundancy. Use DynamoDB global tables to replicate data to a second Region. Modify the application to fail over to the second Region.
• B) Use an AWS managed VPN as a backup to DX. Create an identical DynamoDB table in a second Region. Modify the application to replicate data to both Regions.
• C) Establish a second DX connection for redundancy. Create an identical DynamoDB table in a second Region. Enable DynamoDB auto scaling to manage throughput capacity. Modify the application to write to the second Region.
• D) Use AWS managed VPN as a backup to DX. Create an identical DynamoDB table in a second Region. Enable DynamoDB streams to capture changes to the table. Use AWS Lambda to replicate changes to the second Region.
