A) Eliminated - The X-Ray SDK is used to instrument your application code to create and send trace data to the X-Ray daemon. However, this option alone is insufficient because the SDK only captures traces—it still needs the X-Ray daemon to relay data to the X-Ray service.

Keyword: LEAST amount of configuration; accessed using Amazon API Gateway. AWS X-Ray tracing has been enabled ==> Discard C, D: must write logic in lamba funct extra ==> Discard A: must change code to add annotaion, ... . If not have keyword: 'accessed using Amazon API Gateway. AWS X-Ray tracing has been enabled', it will be correct, because it easier than B B: despite you must know deeply X-Ray to using it (config JSON format, ...), but with conditon in keyword, you just run only cmd './xray --region us-east-1' for working

From doc: The AWS X-Ray daemon is a software application that listens for traffic on UDP port 2000, gathers raw segment data, and relays it to the AWS X-Ray API. The daemon works in conjunction with the AWS X-Ray SDKs and must be running so that data sent by the SDKs can reach the X-Ray service. Running just the daemon won't achieve anything.

Selected Answer: B

. Install and run the X-Ray daemon on the on-premises servers to capture and relay the data to the X-Ray service is the correct option. The X-Ray daemon can be installed and configured on the on-premises servers to capture data and send it to the X-Ray service. This requires minimal configuration and setup. Option A is incorrect because while the X-Ray SDK can be used to capture data on the on-premises servers, it requires more configuration and development effort than the X-Ray daemon. Option C and D are also incorrect because they involve setting up an AWS Lambda function, which is not necessary for enabling X-Ray tracing on the on-premises servers.
