    In the question

    Category: CSAA – Design High-Performing Architectures

    You currently have an Augment Reality (AR) mobile game which has a serverless backend. It is using a DynamoDB table which was launched using the AWS CLI to store all the user data and information gathered from the players and a Lambda function to pull the data from DynamoDB. The game is being used by millions of users each day to read and store data.

    How would you design the application to improve its overall performance and make it more scalable while keeping the costs low? (Select TWO.)

    One of the correct answers is

    Use API Gateway in conjunction with Lambda and turn on the caching on frequently accessed data and enable DynamoDB global replication.

    In here does cache refers to DAX and DynamoDB global replication refer to Global Tables? Or they are separate as well?
