Your company is running a microservice-based application. They are using DynamoDB to store the data and AWS API Gateway for managing the Rest APIs. They are also using Lambda non-proxy integration. The development team recently made a change to one Rest API method. After that, the API does not seem to work as expected. You have been asked to troubleshoot the issue. Which is the correct statement?

Answer options:

A.You can’t change the Rest APIs in AWS API Gateway.
B.As the development team has recently done the change in the method of the Rest API. They should Redeploy the API.
C.As the development team has recently done the change in the stage of the Rest API. They should Redeploy the API.
D.You should change the Cache time-to-live (TTL) value and update the Lambda Code.

Answer: B
Option A is incorrect because we can make changes in the Rest APIs in AWS API Gateway.
Option B is Correct because updates to the method require Redeployment of the API.
Option C is Incorrect because an update to the stage doesn’t require the Redeployment of the API.
Option D is incorrect because it’s not mentioned in the question that they are using the caching.
