Correct answer - "Lambda X-Ray active tracing must be enabled" : To enable tracing on your Lambda
function using the Lambda CLI, you must first add tracing permissions to your function's
execution role If your Lambda function runs on a schedule, or is invoked by a service that is
not instrumented, you can configure Lambda to sample and record invocations with active tracing
Incorrect:
"The IAM permissions" - Incorrect as we already know that permissions were set
"Authorize Lambda source in the X-Ray console" - Not required to set the source
"The X-Ray agent must be loaded with the code" - The X-ray agent is not needed with Lambda
instead AWS X-Ray daemon automatically listens for traffic on UDP port 2000, gathers raw segment
data, and relays it to the AWS X-Ray API.
