Question
A company provides an application to customers. The application has an Amazon API Gateway REST API that invokes an AWS Lambda function. On initialization, the Lambda function loads a large amount of data from an Amazon DynamoDB table. The data load process results in long cold-start times of 8-10 seconds. The DynamoDB table has DynamoDB Accelerator (DAX) configured. Customers report that the application intermittently takes a long time to respond to requests. The application receives thousands of requests throughout the day. In the middle of the day, the application experiences 10 times more requests than at any other time of the day. Near the end of the day, the application's request volume decreases to 10% of its normal total. A DevOps engineer needs to reduce the latency of the Lambda function at all times of the day. Which solution will meet these requirements?
Options
- AConfigure provisioned concurrency on the Lambda function with a concurrency value of 1. Delete
- BConfigure reserved concurrency on the Lambda function with a concurrency value of 0.
- CConfigure provisioned concurrency on the Lambda function. Configure AWS Application Auto
- DConfigure reserved concurrency on the Lambda function. Configure AWS Application Auto
