  • C. X-Ray trace data is not available for querying for 30 minutes after it is captured.

Selected Answer: AB
Given: "SDK" Reason for "A": 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." https://docs.aws.amazon.com/xray/latest/devguide/xray-daemon.html Reason for "B": Q: How far back can I query the trace data? How long does X-Ray store trace data for? X-Ray stores trace data for the last 30 days. This enables you to query trace data going back 30 days. https://aws.amazon.com/xray/faqs/ Why "C" is "not correct": Q: How long does it take for trace data to be available in X-Ray? Trace data sent to X-Ray is generally available for retrieval and filtering within "30 seconds" of it being received by the service.
