Question 1

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.

Linear deployment

Question 3

A company has a website that displays a daily newsletter. When a user visits the website, an AWS Lambda function processes the browser ' s request and queries the company ' s on-premises database to obtain the current newsletter. The newsletters are stored in English. The Lambda function uses the Amazon Translate TranslateText API operation to translate the newsletters, and the translation is displayed to the user.

Due to an increase in popularity, the website ' s response time has slowed. The database is overloaded. The company cannot change the database and needs a solution that improves the response time of the Lambda function.

Which solution meets these requirements?

Options:

A.

Change to asynchronous Lambda function invocation.

B.

Cache the translated newsletters in the Lambda /tmp directory.

C.

Enable TranslateText API caching.
