Question 59 of 65 | ← Chapter 5

Q359. A company hosts an internal serverless application on AWS by using Amazon API Gateway and AWS Lambda. The company's employees report issues with high latency when they begin using the application each day. The company wants to reduce latency.Which solution will meet these requirements?

• A. Increase the API Gateway throttling limit
• B. Set up a scheduled scaling to increase Lambda provisioned concurrency before employees begin to use the application each day. ✓
• C. Create an Amazon CloudWatch alarm to initiate a Lambda function as a target for the alarm at the beginning of each day,
• D. Increase the Lambda function memory

Correct Answer: B. Set up a scheduled scaling to increase Lambda provisioned concurrency before employees begin to use the application each day.

Explanation

B. Set up a scheduled scaling to increase Lambda provisioned concurrency before employees begin to use the application each day:By setting up scheduled scaling, the company can ensure that there is sufficient provisioned concurrency for the Lambda functions to handle the initial surge in traffic at the beginning of each day. This can help reduce latency and improve the overall performance of the application. Increasing the API Gateway throttling limit or increasing the Lambda function memory may not address the issue of high latency specifically caused by the initial surge in traffic. Creating a CloudWatch alarm to initiate a Lambda function as a target for the alarm at the beginning of each day may not scale well and may introduce additional complexity to the solution.
