Question
A developer is building an application that uses an AWS Lambda function to process data. The application requires minimum latency. The Lambda function must have predictable function start times. All setup activities for the execution environment must happen before invocation of the Lambda function. Which solution will meet these requirements?
Options
- AIncrease the memory of the Lambda function to the maximum amount. Configure an Amazon
- BOptimize the static initialization code that runs when a new execution environment is prepared for
- CIncrease the reserved concurrency of the Lambda function to the maximum value for unreserved
- DPublish a new version of the Lambda function. Configure provisioned concurrency for the Lambda

Explanation
Provisioned Concurrency ensures that your AWS Lambda function has pre-initialized execution environments ready to handle invocations with minimal latency, which is critical for applications that require predictable function start times and low latency. This removes the cold start problem by ensuring that all the setup activities (such as loading libraries or initializing execution environments) are completed before the function is invoked.
