Your company is planning to develop an application where the front end is in .Net and the backend is in DynamoDB. There is an expectation of a high load on the application. How could you ensure the scalability of the application to reduce the load on the DynamoDB database? Choose an answer from the options below.

Answer options:

A.Add more DynamoDB databases to handle the load. 
B.Increase write capacity of Dynamo DB to meet the peak loads.
C.Use SQS to assist and let the application pull messages and then perform the relevant operation in DynamoDB.D.Launch DynamoDB in Multi-AZ configuration with a global index to balance writes.

Answer – C
When the idea comes for scalability and decoupling, then SQS is the best option. 
Amazon Simple Queue Service (SQS) is a fully-managed message queuing service for reliably communicating among distributed software components and microservices - at any scale. Building applications from individual components that perform a discrete function improves scalability and reliability and is the best practice design for modern applications. SQS makes it simple to decouple and coordinate the components of a cloud application. Using SQS, you can send, store, and receive messages between software components at any volume without losing messages or requiring other services to be always available.
