    Could you check this question please?


    A tech startup is planning to launch a new global mobile marketplace using AWS Amplify and AWS Mobile Hub. To lower the latency, the backend APIs will be launched to multiple AWS regions to process the sales and financial transactions on the region closest to the users. You are instructed to design the system architecture to ensure that the transactions made in one region are automatically replicated to other regions. In the coming months ahead, it is expected that the marketplace will have millions of users across North America, South America, Europe, and Asia.

    Which of the following is the most scalable, cost-effective and highly available architecture that you should implement?


    Correct answer is a little bit confusing.

    “Create a Global DynamoDB table in your preferred region which will automatically create new replica tables on all AWS regions….”

    But looks like DynamoDB doesn’t automatically create replica tables. It is manual process.

    Hello illerax,

    Thanks for the feedback.

    I’ve reviewed the question and the answer. Based on the AWS documentation, indeed you need to select the regions that you want to replicate your Global Table.

    We will update the question or the answer to reflect this.

    Thanks and regards,
