Selected Answer: BD
A) Eliminated - there is no mention of caching being involved in the problem, this metric is irrelevant for troubleshooting a timeout issue. B) Correct - A high value for IntegrationLatency can indicate that the API Gateway is experiencing delays in receiving responses from Lambda C) Eliminated - this metric is related to caching, which is not mentioned as part of the problem D) Correct - high value for Latency can indicate where delays are occurring overall, including the Lambda function's processing time and any overhead in API Gateway. E) Eliminated - While this metric provides information about the volume of requests, it does not help identify the cause of a timeout or latency issues.
