A developer is building a web application that uses Amazon API Gateway to expose an AWS Lambda function to process requests from clients.During testing, the developer notices that the API Gateway times out even though the Lambda function finishes under the set time limit.

Which of the following API Gateway metrics in Amazon CloudWatch can help the developer troubleshoot the issue?

(Choose two.)

CacheHitCount

IntegrationLatency

CacheMissCount

Latency

Count

Explanations:

CacheHitCount measures how often API Gateway retrieves a response from the cache, which isn’t relevant to Lambda timeouts.

IntegrationLatency shows the time taken for API Gateway to interact with the Lambda function, helpful for troubleshooting API Gateway timeouts.

CacheMissCount tracks missed cache hits, which isn’t relevant to the Lambda execution time or API Gateway timeouts.

Latency measures the total time from when the request is received by API Gateway until a response is sent back, encompassing Lambda execution and other factors.

Count simply tracks the number of requests made to API Gateway, which does not provide insight into the time-related issue or Lambda processing.
