Correct answer - "X-Ray sampling": X-Ray SDK applies a sampling algorithm to determine which
requests get traced however because our application is failing to send data to X-Ray it does not
help in determining the cause of failure.
Incorrect:
"EC2 X-Ray Daemon" - The daemon logs could help with figuring out the problem.
"EC2 Instance Role" - Eliminates API permission issues (in case the role doesn't have IAM
permissions to write data to the X-Ray serivce)
"CloudTrail" - We could check CloudTrail to see if any API call is being denied on X-Ray
