You are a solutions architect working for a data analytics company that delivers analytics data to politicians that need the data to manage their campaigns. Political campaigns use your company’s analytics data to decide on where to spend their campaign money to get the best results for the efforts. Your political campaign users access your analytics data through an Angular SPA via API Gateway REST endpoints. You need to manage the access and use of your analytics platform to ensure that the individual campaign data is separate. Specifically, you need to produce logs of all user requests and responses to those requests, including request payloads, response payloads, and error traces. Which type of AWS logging service should you use to achieve your goals?

Answer options:

A.Use CloudWatch access logging
B.Use CloudWatch execution logging
C.Use CloudTrail logging
D.Use CloudTrail execution logging

Correct Answer: B
Option A is incorrect. CloudWatch access logging captures which resource accessed an API and the method used to access the API. It is not used for execution traces, such as capturing request and response payloads.
Option B is correct. CloudWatch execution logging allows you to capture user request and response payloads as well as error traces.
Option C is incorrect. CloudTrail captures actions by users, roles, and AWS services. CloudTrail records all AWS account activity. CloudTrail does not capture error traces.
Option D is incorrect. CloudTrail does not have a feature called execution logging.
