  • A. Install and run the X-Ray SDK on the on-premises servers to capture and relay the data to the X-Ray service.
  • B. Install and run the X-Ray daemon on the on-premises servers to capture and relay the data to the X-Ray service.
  • C. Capture incoming requests on-premises and configure an AWS Lambda function to pull, process, and relay relevant data to X-Ray using the PutTraceSegments API call.

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.

If not have keyword: 'accessed using Amazon API Gateway.

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.
