The developer needs to resolve the error without modifying the Lambda function code.

Which solution will meet these requirements?

Question 38

A company ' s application has an AWS Lambda function that processes messages from loT devices. The company wants to monitor the Lambda function to ensure that the Lambda function is meeting its required service level agreement (SLA).

A developer must implement a solution to determine the application ' s throughput in near real time. The throughput must be based on the number of messages that the Lambda function receives and processes in a given time period. The Lambda function performs initialization and post-processing steps that must not factor into the throughput measurement.

What should the developer do to meet these requirements?

Options:

A.

Use the Lambda function ' s ConcurrentExecutions metric in Amazon CloudWatch to measure the throughput.

B.

Modify the application to log the calculated throughput to Amazon CloudWatch Logs. Use Amazon EventBridge to invoke a separate Lambda function to process the logs on a schedule.

C.

Modify the application to publish custom Amazon CloudWatch metrics when the Lambda function receives and processes each message. Use the metrics to calculate the throughput.

D.

Use the Lambda function ' s Invocations metric and Duration metric to calculate the throughput in Amazon CloudWatch.
